Patent GB-195928-A (GB)
Abstract: 195,928. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Bellamy, J. I., and Wicks, J.). April 5, 1922, [Convention date]. Addition to 169,698. Automatic exchange systems.-In a system in which connections from group selector banks to trunks F are made through non-numerical switches E, when only one switch of a sub-group is standing on an idle trunk, all the idle switches standing on busy trunks are caused to hunt until an idle trunk is found, but means are provided to prevent hunting if no trunks are available. The trunks F and switches E are divided into subgroups according to the capacity of the switches, and the lines from the group selectors are divided between the sub-groups to render all the trunks accessible to each selector. The test contact 51 of each switch E is directly connected to the test wiper 63 to render an idle switch standing on a busy trunk non-selectable. A marginal relay 88 individual to the set of switches E accessible to the same group selector is connected up in series with a resistance 85 in each switch, which is short-circuited by the energization of a relay 56 over the test wiper 63 when the switch stands on a busy trunk. When only one resist. ance remains in circuit, that is, when only one switch stands on an idle trunk, the relay 88 operates, energizing a relay 89 which completes circuits for the rotary magnets 58 of the idle switches of the set, those of the magnets of the busy switches being broken by the energization of a relay 57 over the test circuit. Hunting takes place until an idle trunk is found, when the relay 88 releases and stops the movement. The relay 57 is designed to operate more quickly than the rotary magnet 58 to prevent rotation of a switch seized during the hunting movement. A chain relay 92 is controlled by the release relays 72 of the repeaters associated with the trunks of a subgroup, and operates if all the trunks are busy to open the rotary magnet circuits of the switches having access thereto.

Title: Improvements in or relating to feeder mechanisms for a pneumatic conveyor
IPC: B65G53/08
Filed: 1947-07-23
Abstract: 645,753. Pneumatic conveyers. COLBURN, R. R. July 23, 1947, No. 19738. Convention date, Feb. 2, 1942. [Class 78 (i)] [Also in Group X] A pneumatic feeder comprises a granular material supply hopper 13 having a discharge opening for the granular material; a carrier 10 having a series of upright pockets 9 revolvable about a vertical axis adjacent to said supply hopper to periodically expose the upper ends of successive pockets to said opening for the reception of granular material from the supply hopper; means 23 for injecting air under pressure into each of the successive pockets to eject granular material from the opposite ends thereof after said pockets have been sealed from said supply hopper; and means 45 for venting the successive pockets only after said ejection of the granular material has been effected and before said pockets are again brought into communication with said feed opening. Rotor carrier 10. Figs. 5, 6.-Material is fed from hopper 13 by agitator 42 and falls through aperture 34 onto a liner-fitted pocket 9 of rotor carrier 10. The pocket 9 rotates until it comes under air jets 44 from air inlet pipe 23 when it is discharged, and the material passing through outlet 29 to screw conveyer 17 which conveys it towards the outlet. As the pocket rotates further it comes underneath air vent 45 and residual air escapes from the pocket which then rotates to receive material from aperture 34. Hopper 13 is fixed to casing 12 and screws 38 journalled in hopper extension 32 bear against movable bottom plate 33 which has lugs 36 sliding in slots 37 of the casing so as to force the bottom plate 33 against the rotor 10 and prevent escape of air. Sealing discs 40 and 39 are secured respectively to bottom plate 33 and the casing 12 and further serve to prevent escape of air. Each pocket 9 is filled with removable liner 43. Screw. Figs. 2, 6.-Screw 17 conveys material received from the rotor 10 via passage 29 and conveys it to the rubber lined discharge pipe 20. The screw has shaft 18 which is journalled at its rear in a single bearing 46 and which, at its fore, carries revolving scraper 55 shaped to conform to nozzle 16. Nozzle 16 is formed in several parts 47, 48, 49, each of which is fed by air which passes via pipes 52 and annular channels 54 and radial openings 50 to the interior of the nozzle. Nozzle part 49 may be lined with rubber and be interchangeable. The materials used may be those for making cement and a stream of water may be introduced to the stream of material at the mouth end of discharge pipe 20.

Title: Domestic hot water supply systems
IPC: F24H1/20
Filed: 1961-06-01
Abstract: 930,702. Hot water supply systems. JOHN WHITEHOUSE & SONS Ltd., and H. GOODMAN. May 2, 1962 [June 1, 1961], No. 19806/61. Class 64 (1). A domestic hot water storage cistern of the type in which the water is replenished from a floatcontrolled cold water tank fed from the mains has a partition 13 dividing the cistern into upper and lower chambers 12a, 12b and has an immersion heater 18 in the lower chamber. The partition 13 has two openings from one of which an insulated tube 20 extends downwardly to the base 11 of the tank enclosing the immersion heater but having an opening 21 near its lower end to allow for circulation of water into the tube, up past the heater and thus into the upper chamber 12a. Cold water is displaced through a short pipe 22 extending downwardly from the other opening into the lower chamber 12b. The opening 19 may alternatively take the form of a short upstanding pipe 28. Air is trapped between the surface of the water in the lower chamber and the partition 13 by reason of the presence of the pipe 22 and serves to insulate the upper chamber from the lower. Draw-off means 23 are connected to the upper chamber 12a so that a reasonable quantity of hot water is available quickly after switching on the heater. The cistern may be constructed, as shown, as an integral unit with the cold water feed tank 16, a layer of insulating material 17 being included between the hot and cold water sections.

Title: Improvements in and relating to fuel distributor systems for fuel injection type internal combustion engines
IPC: F02M41/06
Filed: 1958-06-20
Abstract: 870,341. Regulating; rotary valves. GREEN, G. W. A., and FOX, G. B. June 18, 1959 [June 20, 1958; July 17, 1958], Nos. 19817/58 and 22967/58. Class 7(6). [Also in Group XXVIII] In a rotary fuel distributer wherein an axially displaceable rotor with a tapered timing and metering gash in its periphery, co-operates with distribution ports in the stator, a spring-loaded fuel pressure relief valve is arranged so that the axial position of the rotor controls the spring- loading of the valve and thereby the fuel pressure at the metering gash. In Fig. 1 fuel under pressure is supplied from pump D through duct E and annulus F to the gash G in the rotor A. The gash G registers in turn with ports H in the stator B to feed the injectors via ports K. After injection a spill gash L, Fig. 2, registers with the port H to relieve excess fuel into the space M from where it flows through passage N and shaft C into space O to feed the suction passage P of the pump, fuel being admitted to the circuit through Q. Axial movement of the rotor A to the right is effected by means of a resiliently linked forked member U which is rotated by shaft T linked to the engine control member, this movement serving to increase the effective pressure of the spring S thus increasing the pressure in the annulus F on the pressure side of the relief valve R and at the same time increasing the duration of injection due to the increased peripheral width of the gash G. In another embodiment Fig. 1A fuel is admitted at Q, is pumped to the annulus F whence it has access to the underside of the relief valve R. Discharge from the valve R and the spill gash L passes through channels N and W to the right hand end of plunger Z which slides in the plug Y and is forced to the right by a spring 2. Fuel in the chamber at the right hand end of the plunger Z passes via a hole 3 and a tapered slot 4 escapes by the passage 5 and the port W1 to the space M. The arrangement ensures that the rod 6 protrudes from the rotor by an amount dependent on the speed of the engine and should the rotor be pushed by the control shaft T and lever V more to the right than the position giving full torque fuel at that speed then the rod 6 closes the orifice 10 to allow fuel pressure to build up in the space M thus causing the rotor to move to the left to reduce the fuel supply.

Title: Improved method of preparing formed collagen
IPC: B60R1/12
Filed: 1962-05-23
Abstract: A leather-like material is made by mixing collagen fibres with water to form a doughy pulp having a pH value between 5.0 and 8.0; heating the pulp at a temperature between 40 and 65 DEG C. to solubilize a portion of the collagen therein without appreciably shrinking the fibres; continuing the heating until at least 5% by weight of the collagen in the pulp has been solubilized while the major portion remains in fibrillar form; and forming the pulp.  In a preferred embodiment, the collagen fibres are prepared from the corium layer of unlimed cattle skins by beating in an aqueous slurry in a paper beater.  The fibres are subsequently dewatered. The fibres are formed into a doughy pulp containing 10 to 25%, preferably 12 to 18%, solids by weight and having a pH between 5.5 and 7.0.  The pulp is heated to between 54 and 62 DEG C so that there is little fibre shrinkage and little formation of gelatin.  The heating is continued until up to 30% by weight of the collagen has been solubilized.  The pulp may be extruded on to a moving conveyer to form sheets or filaments or may be moulded to produce solid or hollow bodies, the forming preferably being carried out between 35 and 55 DEG C.  Sheets may then be passed over chilled rollers at a temperature between 2 and 10 DEG C. and may be needled. The formed and set collagen may be subjected to the action of a protein precipitating agent or may be tanned using a chrome tanning agent.

Title: Improvements in or relating to electric relays
IPC: H01H47/12
Filed: 1925-08-07
Abstract: 238,540. Cardwell, A. D. Aug. 15, 1924, [Convention date]. Thermionic relays; controlling apparatus. - The energizing current of a relay is decreased by the receipt of a signal thereby causing the actuation of the armature which is then automatically restored to its original position. In the arrangement shown in Fig. 1, the relay 17 is energized bv a circuit including a battery B<1> and the anode 12<a> of a thermionic valve 1<a> so as to hold its armature 18 against a contact 21. A wireless signal. which is rectified and amplified in known manner, gives to the grid 2<a> a negative potential which decreases the current through the relay 17 and causes the release of the armature 18 which may, for example, cause another relay 23 to close a working circuit 49. The armature 18 when released strikes a contact 24 which then charges the grid 2a to a positive potential, increases the current through relay 17 and restores the armature to its normal position so that if the signal continues the armature is maintained in .vibration. with comparatively long periods in the attracted position while the negative grid potential is being built up if the signal is a weak one. The relay 23 may be adjusted so that the circuit 49 is closed during this vibration. According to a modification, the armature 18 may be restored by a spring pressed lever normally held back by an electromagnet, the circuit of which however is broken when the armature 18 is released from its attracted position; and according to another modification. the armature 18 is restored by an increase in the current through the relay 17 caused by the grid of a second thermionic valve being charged to a positive potential when the armature 18 is released. Fig. 5 shows in detail the relay 17, which comprises an adjustable horse-shoe magnet 17<a>, with coils 17 on its poles, and an armature 18 adjustable by means of a spring 26, one end of which is connected to a cord wound round a rotatable shaft 28. The Specification as open to inspection under Sect. 91 (3) (a), refers also to a relay the energizing current of which is increased instead of decreased by the receipt of a signal. This subjectmatter does not appear in the Specification as accepted.

Filed: 1924-08-23
Abstract: 220,961. British Thomson-Houston Co., Ltd., (Assignees of Benford, F. A.). Aug. 24, 1923, [Convention date]. Lenses more particularly for use as condenser lenses in optical projection apparatus, are constructed with more than two sections 18, 20, 22, 24, formed by removing portions from the uncut lens along planes 16, 17, passing through the axis of projection and bringing the sections into contact as shown in Fig. 3. Each part of the lens so formed produces a separate and distinct image of the arc 2 at the gate 4, resulting in a greater evenness of illumination of the film 4<a>. Alternatively, two lenses A, B may be formed of two sections each, the lines of the sections being placed at right-angles. In further modifications the sections may be made at angles of 60‹ with one another or three split lenses may be used having the sections at 60‹ with each other. When formed of four sections the axes of the sections may be arranged along a line by only removing a portion of the lens only along one axis and simply cutting the lens along the axis at rightangles to that along which a portion of the lens was removed. The focal points of all the sections lie in a common focal plane.

Title: Improvements in or relating to wireless direction finding systems
IPC: G01S1/02
Filed: 1927-07-28
Abstract: 299,507. Smith, R. T., and Smith, C. H. July 28, 1927. Directive signalling ; aerials.-Signals received on a rotatable frame aerial 1 are combined with those received on a non-directive aerial 2, a high resistance 13 in series with the latter serving to bring the two signal voltages into phase and also to equalize the relative signal strengths. When the swtch 9 is on the terminal 10, the aerial 2 serves to pick up and supply the transmitting station through a coil 8 coupled to a coil 6 and a coil 5 coupled to a coil 7. The same switch is then moved over to contact 12 so as to insert the resistance 13 into the aerial circuit. At the same time the frame 1 is rotated to the " minimum " position, which is identified by the fact that no change in signal strength occurs on either side of the reversing switch 15. The combination of the directive and non-directive aerial also serves to eliminate the usual direction ambiguity, by virtue of the definite change of signal strength which occurs as the frame 1 is moved to one side or other of the critical position. As applied to an aeroplane the frame 1 extends between the wings so that its plane is perpendicular to the fore-and-aft line of the machine, whilst the aerial 2 is a trailing wire which may be held in a position of symmetry by means of a ring supported by stay-ropes from the fuselage.
