Title: Improvements in the manufacture of slush moulded hollow articles
IPC: B29D22/00
Filed: 1954-05-31
Abstract: 747,319. Moulding hot water bottles &c. from resinous material. UNITED STATES RUBBER CO. May 31, 1954 [Aug. 3, 1953], No. 16047/54. Class 87(2) A plug fitting is moulded integrally in a hollow slush moulded article, e.g. a hot water bottle. by allowing resinous material in liquid form to drain from the mould into a channel defined by the inner wall of the mould a member which projects into it and a sheet of plastic material, and causing the resinous material to solidify. A mould 19, on the inside of which a skin has been formed by a slush moulding a vinyl resin plastisol as described in Specification 725,100 is inverted so that its neck 22, which widens as shown in Fig. 1, encloses the outer part of a sheet 17 of fused vinyl resin, Fig. 1 showing a section on the major axis of an elliptical sheet. The sheet has a horizontal portion which rests on a supporting dam 14 carried by struts 18. The mould carries arms 21 which, when the mould is inverted rest on support stops 13, on posts 12. The support dam 14 has a sleeve 16 which projects into the mould and forms a channel between it and the neck 22, closed at the bottom by the sheet 17. Extra plastisol resin remaining in the mould when it is inverted fills this channel and overflows the edge of the sleeve 16, excess draining through the sleeve and through an opening 11 in the support base. Heat is then applied to fuse the plastic material 20 on the wall of the mould and the plastic material 24 trapped in the channel, so forming a plug wall integral with the wall of the hollow article and the sheet. The invention is primarily for application to the moulding of hot water bottles. A screw threaded ferrule 25 may be supported on the dam 14 to be moulded into the material of the bottle for the usual screw threaded plug. The time for fusing the resin 24 may be reduced by placing an elliptical ring 26, Fig. 3, on the sheet 17 so that it partly fills the channel and leaves less space to be filled by the excess material requiring fusing.

Title: Improvements relating to oil-heated hot water radiators
IPC: F24H3/00
Filed: 1950-06-27
Abstract: 680,493. Towel rails. MORRIS HEATING APPLIANCES, Ltd., and TOLCHER, J. H. June 27, 1951 [June 27, 1950], No. 16048/50. Class 52(v) [Also in Groups XI and XIII] A long oil reservoir 24 extends beneath the horizontal water pipes 6 of an oilheated hot-water radiator or towel rail and rests on feet 20, 22 which support the rail. Moreover, the reservoir carries at one end a burner 26 with a sleeve 36 which can be raised and lowered to engage and disengage the bottom 40 of a chimney 30, 32 encasing part 28 of the Water system; at its other end the reservoir is engaged on one of the feet 20 so that it is held in position as a whole when the sleeve is engaged with the chimney but when the sleeve is disengaged it can be swung clear of the chimney, see Fig. 3, and removed e.g. for re-filling. The sleeve 36 has a mica window 50 and also pins, one extending as a handle 46, co-acting with inclined slots 44 in the burner 26 so that rotation by the handle raises the sleeve to engage the half-lip 40 of an inner coaxial shell 30 of the chimney. The rail is filled with water poured into pipes 4, 6, through an opening normally closed by a cap 12, until it overflows through a hole in an upright 4 before the hole is closed by a screw 14. The bottom pipe has tubular legs 16 terminating in the flat feet 20, 22 screwed to the floor. A clip 34, pivoted at its centre 38, Fig. 3, to the foot 20 for easy removal of the reservoir 24 and burner 26, holds the reservoir at the one end or the clip may-be dispensed with and the foot 20 upturned at its outer end, Fig. 5 (not shown). At the top of the reservoir a filling opening 52 and a level indicator 54 are provided. The Provisional Specification refers also to each supporting foot and leg as being made from a single metal strip and to the outer shell of the chimney as being perforated.

Title: Improvements relating to coin discriminating devices
IPC: G07D5/08
Filed: 1966-04-12
Abstract: 1,140,232. Testing coins. INTERNATIONAL NICKEL Ltd. 12 April, 1966 [21 May, 1965], No. 16070/66. Heading G4X. In a coin discriminator for distinguishing coins containing a certain amount of a ferromagnetic material from all other coins, the coin under investigation is inserted, through slot 21, Fig. 2, into a pocket 22A in a coil 11 forming part of an oscillator (13), Fig. 1 (not shown), the output of which is fed to a frequency selector (15), e.g. a filter or reed relay, Fig. 11 (not shown). For a particular oscillator frequency arranged to be less than 50 kc/s, obtained when a coin having the required magnetic characteristics is inserted in the coil, the selector (15) operates a relay (16) which causes the coil to be directed into an "accept" passage 25, all other coins being directed to "reject" passage 26. The coil is wound on a plastics rotor 22, weighted by a counter-balance 27 so that in the absence of a coin it remains in -the position of Fig. 2. When a coin is dropped into the slot, the rotor unbalances and rotates clockwise, until it is brought to rest against either stop 30, moved into position by the operation of relay 16, whereupon the coin falls out of the coil into the "accept" passage, or fixed stop 31 with the pocket 22A above the "reject" passage 26. If a coin of strongly ferromagnetic material e.g. a washer or slug, is inserted into the device, it is held by magnet 29, positioned just below the slot 21, above the pocket 22A. Operation of a coin reject plunger 32 then causes the rotor to rotate clockwise until a coin reject pocket 44 is positioned beneath the slot. Simultaneously the coin is knocked off the magnet by a pivotable arm 38 into the pocket. Release of the plunger allows the rotor to rotate back to its original position thereby depositing the coin in the "reject" passage. If a light weight coin is inserted into the device such that the rotor is not overbalanced, operation of the reject plunger causes rotation of the rotor as above so that the coin is deposited in the "reject" passage. The relay 16 may be connected to indicating or signalling devices, e.g. switches, lights, audible alarm, cameras &c. which signal and/or record the presence of a spurious coin. For example, in a highway toll-collecting device, the relay could be so connected that a light remains red upon deposit of a spurious coin but turns green upon deposit of an acceptable coin.

Title: Improvements in or relating to means for the control of the quantity of scavenging air supplied in two-stroke cycle internal combustion motors provided with a scavenging fan
IPC: F02D9/00
Filed: 1941-12-12
Abstract: 550,407. Regulating. TRIGGS, W. W. (Aktiebolaget Atlas Diesel.). Dec. 12, 1941, No. 16081. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 15, 1942.] [Class 7 (vi)] [Also in Group XXIX] In two-stroke engines supplied with scavenging-air by a fan 23, the inlet 24, or the outlet 25, of the fan, or both, are controlled by a throttle valve 2 adjusted automatically by the governor of the fuel pump, connected at 18, either directly or through a servomotor 6, to which fluid pressure such as scavenging-air pressure, is admitted by a pipe 8 controlled by a slide valve 11 connected by a lever 15 to the fuel-pump governor 16. The valve 11 has a recess 13 which tapers axially, and the servomotor cylinder 6 is fitted with an adjustable escape 17. When the load on the engine decreases, the throttle is moved towards the closed position, and vice versa. The engine may be controlled from a distance by electric or pneumatic means which may actuate the control of the fuel pump, the throttle being adjustable automatically; or it may directly actuate the throttle.

Title: Improvements in or relating to radio receiving systems
IPC: H04B1/12
Filed: 1924-07-08
Abstract: 219,305. Electric Apparatus Co., (Assignes of McCaa, D. G.). July 18, 1923, [Convention date]. Atmospherics and undesired signals, eliminating or limiting; thermionic heterodyne receivers.-A high frequency receiving system for distinguishing between desired and interfering signals or atmospherics comprises a signal translating circuit for producing desired signals coupled to a detuned aerial circuit in which local oscillations, representing at least in part local energy, are caused to change the natural period of the aerial circuit so that it approaches or equals the period of the desired signals. In a modification the aerial circuit is detuned and coupled to a similarlytuned circuit both electrically and magnetically and a receiving circuit tuned to the desired signal is connected to a point of the circuit of substantially zero potential for oscillations of the aerial at its natural period. Fig. 1<a> shows one arrangement, the circuit L<3>, C<2>, C<6>, being tuned to the desired signals and the aerial circuit detuned, preferably by closing switch S<1>, shunting coil L by a smaller coil F, thus reducing the wave length. Circuit S, L<1>, C<1>, C<6> is tuned to the aerial circuit, and an anti-node X in the aerial circuit is coupled to a point Y, common to the two closed circuits, by a. condenser C<5>, and this coupling and the coupling between the coils S, P are so adjusted that they neutralize one another and cause no electromotive force to exist across the condenser C<6>. Part of the desired signals, however, pass by way of the coupling X, C<5>, Y and condenser C<6> to earth at a and are thus applied to valve V. The latter is back-coupled through the coil D to the detuning coil F, thus excluding signal energy from this coil so that the coupling through X, C<5>, Y is enhanced and signals strengthened. Various modifications are described, showing the use of a loop-aerial, substituting electromagnetic for electrostatic coupling between the two closed circuits, and employing resistance coupling instead of capacity coupling between the points X, Y. Fig. 5 shows a further modification in which a high frequency valve V<1> supplies the back-coupling to the coil F, and a heterodyne source H is coupled through transformer t for the reception of undamped waves. This arrangement may be utilized for receiving undamped waves by arranging the switches so that the valve V<1> and all connections below switch X<1>, are omitted and a heterodyne source I is connected to the coil F.
Patent GB-957362-A (GB)
Title: Improvements in or relating to processes for the production of melamine
IPC: B01J19/00
Filed: 1962-04-30
Abstract: Melamine is produced by heating urea under pressure in a vessel lined with non-metallic materials, using an electrical heating element of a conductive, non-metallic and corrosion resistant material (other than urea itself) in the interior of the reaction vessel. A pile or uniform structure of conductive material may be used, which can be permeated with non-conductive or less conductive material to provide a rising or falling conductivity characteristic in the direction of flow of the urea. The reaction is performed so that liquid urea flows countercurrent to the gas phase produced. This gaseous phase, consisting of ammonia and carbon dioxide may be cooled without pressure change and converted into urea and then recycled. An A.C. current is preferably used and the heating element may be made of carbon, silicon carbide, or graphite. The reactor lining may be of carbon or graphite, if it is to be used as an electrode, or it may be of e.g. kaolin, corundum, or magnasite. A catalyst may be used for the reaction which may be a metal, or metal oxide or salt (see Specification 754,720).

Filed: 1936-06-15
Abstract: 481,952. Conduits. UNITED STATES RUBBER PRODUCTS, Inc. June 15, 1936, No. 16629. Void. Convention date, June 14, 1935. [Class 36] Apparatus for inserting conductors C<1>, Fig. 8, in passages P in a vulcanized rubber or like flexible conduit S and for applying a fabric tape T<1> to the recessed upper face of the conduit comprises a capstan C, Fig. 1, adapted to draw the conduit from a drum R over a table T on which it is operated on successively by a buffing wheel B, rotary knives K, a conductor-inserting device G, a washing device D and a tape-applying device D<1>. The buffing wheel B, which is driven by a motor M, grinds off the skin of the recessed upper face of the conduit so that it will take the adhesive for securing the tape T<1> in the recess. The conduit is adjustable relatively to the buffing wheel and a blower 6 is provided for removing the buffed particles. The knives K, which are also driven by the motor M, cut slits S<1>, Fig. 8, in the walls of the conductor passages P, through which slits the conductors C<1> are led into the passages by fingers F of the conductorinserting device G. The conductor-inserting device comprises a hopper H containing a lubricant, such as talc, through which the conductors pass before being led to the fingers F which extend through the slits in the conduit and guide the conductors into the passages P. Any tale falling from the conductors on to the upper face of the conduit is removed by the washing device D which comprises an endless felt band 32 pressed into contact with the conduit by rolls 35 and passing through a tank 38 containing cleansing fluid, such as gasoline. The band 32 is driven under the rolls 35, in direction opposite to the direction of travel of the conduit, by a wheel 33 which is driven from an annular track 34 on the capstan C. The capstan is driven by the motor M. The tape-applying device D<1> comprises an endless belt 45 which contacts with the upper face of the conduit and conveys adhesive from a roll 48 dipping in adhesive in a tank 43 to the upper face of the conduit. The tank 43 also contains a roller 42 which applies adhesive to the tape T<1> as it passes from a reel 41 to the roller 44 which presses the tape into the recess in the upper face of the conduit. The buffing and slitting operations may be carried out by apparatus as shown in Fig. 1 and the conduit then transferred to another machine having pads soaked with liquid for cleaning the conduit, and including a drum around which the conduit passes, the conductors being inserted into the passages and the tape being applied to the recessed surface of the conduit whilst the latter passes around the drum. The conduit then passes to a drying chamber. The conductors are led upwardly into the passages to prevent the recessed face of the conduit from being fouled with the material used for lubricating the conductors.

IPC: B60G17/044
Filed: 1965-04-21
Abstract: 1,134,695. Hydropneumatic shock absorbers. GIRLING Ltd. 21 April, 1966 [21 April, 1965], No. 16727/65. Heading F2S. In a suspension system, including at least one strut in which a piston 2, preferably valved, works in a cylinder 1 preferably provided with a port 7 which communicates with an annular reservoir 5 having a captive gas-bubble 6, the cylinder 1 includes passages 8, 9 which lead preferably to one-way valves 10, 11, respectively, and which communicate with a single port 12 coupled, by a union 13, to an outlet (14) of an hydraulic pump, Fig. 2 (not shown), the passages 8, 9 being controlled by a valve 15 which, under the influence of the piston 2, controls the flow of fluid to and from the cylinder in such a manner that the length of the strut is maintained substantially constant despite variation of the vehicle loading of the strut. The valve 15 is pivoted to an end wall of the cylinder at 16 and is coupled by tension springs 17, 18 to the piston and cylinder respectively, the tension of the spring 18 being adjustable from outside the cylinder by a set-screw 19. The pump comprises an inlet pipe (21) which leads to a reservoir, not shown, a piston (22) which works in a cylinder (25) and is urged by a spring (24) into contact with an engine-driven eccentric (23), a one-way valve (27), and a pressure relief valve (28). At normal loading the springs (17), (18) hold the valve 15 in an intermediate position to throttle partially the passages 8, 9 to an equal extent so that, with the pump operational, no fluid enters the cylinder 1, the valve 28 spilling back any liquid due to excess pressure of the pump. Increase of load causes the valve 15 to lift off the passage 8 and close the passage 9 so that fluid enters the cylinder through the port 12 and the piston descends until the springs 17, 18 restore the valve 15 to its initial position. For loads below normal the piston descends so that the spring 17 predominates and allows the valve 15 to open the passage 9 and fluid to escape through the port 13. Unloading the vehicle allows fluid to flow through the passage 9 and bleed away through a bore (29) in the valve (27) of the pump until the valve 15 again closes the passage 9. The valve 15 may be replaced by a single bobbin valve movable in response to the position of the piston 2. As shown, the strut comprises a principal support for the vehicle; it may, however, be incorporated to trim the level of a main mechanical, rubber, or air spring.
