Title: Improvements in the wireless control of selective switches or the like
IPC: F41G7/00
Filed: 1918-04-02
Abstract: 195,410. Low, A. M. April 2, 1918. Controlling and actuating torpedoes @c-In a system cf control of torpedoes, aeroplanes, &c., the emitted waves are broken up into timed impulses by a rotary make-and-break switch, and at the receiver a selective switch is operated only when the received impulses are of the cortect frequency. Fig. 1 shows the transmitting circuits, Fig. 2 the receiving circuits, Fig. 3 the receiving selector, aM1 Fig. 6 the impulse sender. The sending-apparatus, Fig. 1, is provided with a number of push switches p<1> - - p<4>, each in circuit with a relay o<1> - - o<4>, and each adapted to control a separate function at the receiver. An arm q rotated by clockwork puts the wireless transmitting apparatus in circuit consecutively with the armatures of the relays o<1>- - -0<4>. The pushes p<1> - - p<4> when depressed n,T.e held down by latches until the arm q has passed the corresponding contact n<1> - - n<4> and are then released. The transmitting circuit also includes a rotary make-and-bpeak switch @ by which the emitted waves are broken up. This may be of the form shown in Fig. 6, in which a disc 9, rotated by a motor through worm gear 10 and a friction clutch, carries loosely on its spindle an arm 13 and a spring blade. The arm 13 is connected by a spring, to a pin on the disc 9, and its outer end strikes a number of pins 14 and makes and breaks contact between the blades and a contact 15 carried on the disc 9. Connections are made to brushes engaging concentric rings 16 on the disc 9 wired respectively to the contact 15 and to the blade. The disc is normally held by a spring pin engaging a recess 17. The received impulses energize a magnet 1, Figs. 2 and 3, and cause a pawl connected to its armature to engage rapidly and repeatedly with teeth on the rim of a wheel w which is spring-controlled or otherwise loaded so as to be actuated only by impulses of correct frequency. The wheel w may actuate a rotary switch of usual form, or it may operate an arm 2 the outer end of which wipes over the nearer insulated face of an inclined plate 3. On reaching the top of this plate, the arm 2 falls on the farther side of the plate 3 and makes contact with its rear conducting surface. A circuit is thus made through one or other of the magnets 5 - - 8, according to the position at the moment of the arm q<1>, which is driven synchronously with the arm q at the transmitter. The clockwork driving the arms q, q<1> may be replaced by synchronous motors, or by balance-wheel devices which complete a circuit at the end of each swing, and so energize a coil to reverse, the swing. Several wheels such as w may be used, only cne a being correctly adjusted to respond to the timed impulses. The teeth on the wheel w may be irregular so as to respond to a sequence of impulses of different frequency; or two wheels may be arranged side by side, the contact member being operated onLy when both rotate at the same speed.

Abstract: 514,480. Coating-compositions. OXVAR, Ltd. (Oxford Varnish Corporation). April 8, 1938, No. 10744. [Class 95] [Also in Group IV] In the production of coating-compositions a paste of light reflecting metallic particles is mixed with a carrier substance containing a volatile solvent, and after thorough mixing, the heavier metal particles' are allowed to settle and the supernatant liquid containing the finer particles is decanted or otherwise removed from the sediment. The carrier may be a lacquer gum in a volatile solvent, or an oil varnish, or there may be used a mixture of mineral spirits and a high-flash naphtha. After the heavier particles have, been separated, the suspension may be mixed with other vehicles, pigments, dyes, or other materials to form the final coating composition. The metal pigments may be aluminium flakes or bronze powder. The particles may have an average flake' particle area of not more than 5 x 10<-7> sq. cm. In an example, aluminium flake is mixed with mineral, spirits and high flash naphtha, and the heavier particles are then allowed to settle. The suspension is then mixed with a xylene solution of a lacquer gum or a phenol-modified alkyd resin.' For use the solution may be diluted to a spraygun consistency by adding mineral spirits and high-flash naphtha. After the composition has been applied to a surface, there may be applied a clear lacquer so as to give the surface a subdued iridescent appearance. The metallic coating may be used as a ground. coating for overlying wood grain designs, marble and other effects. Specification 514,479, [Group IV], is referred to.

Title: Bearing cap
IPC: F16C9/02
Filed: 1960-03-28
Abstract: 910,046. Bearings. NATIONAL LEAD CO. March 28, 1960 [May 21, 1959], No. 10840/60. Class 12 (1). [Also in Group XXII] A bearing cap comprises a body 10 of light metal and a compensating member 30 fixed thereto having a lower coefficient of expansion. The cap has finished locating surfaces 12, 13, 14, 15 on a body formed by pressure-die-casting aluminium on to a roughened and undercut castiron base 30 as described in Specification 881,258. Alternatively, in the base, holes may be drilled, or slots milled, which are filled by the cast metal. The cooling of the cast metal causes the ends of the base to bow upwardly. Thus, when the body expands in use, the centre of the body moves upwardly and compensates for an increase in clearance at the shaft due to heating. The compensation is on the vertical diameter only, the clearance along the horizontal diameter increasing. In further modifications, the body and base are serrated and bolted together or strips of the base metal are let into the sides of the body.

Abstract: 856,219. Ventilating valves. BARBERCOLMAN CO. April 1, 1959 [April 14, 1958], No. 11084/59. Class 137 [Also in Group XXIX] Flow of air through a duct 10 of circular, square or other cross-section is controlled by an umbrella-like closure member 12 with its apex pointing downstream; the member 12 consists of a flexible rubber or plastic disc 14 secured to wire ribs 15. The ribs 15 may be embedded in the disc during moulding, inserted in eyes formed on the back outer edge of the disc or disposed between two discs the parts of which between the ribs are held together by heat sealing. The disc 14 is centrally apertured and the inner edge is bonded or clamped to an axially-slidable ring 18, movement of which controls the opening and closing of the member 12; the ring 18 embodies a nut 19 and is formed with sockets in each of which is disposed the ball-end of a rib whereby the latter may swing in a radial plane. The ball and socket joints may be replaced by an "L" or "T" shaped piece on the inner end of each rib housed in a plain-bearing surface in the ring 18, and each rib is fulcrummed at a bent part 31 near its inner end on a ring 27 secured to the duct 10 by a cross-bar 29, the ring 27 flaring outwardly and having spaced radial notches into which the parts 31 enter as the valve closes; part 31 may be formed by a thickening of the disc around the rib instead of bending the latter. The ribs 15 may be of resilient wire looped near the inner periphery of the disc 14 with the end opposite the rib secured to the nut 19. The valve is operated by manually rotating a shaft 35 a threaded 41 part of which is engaged by the nut 19 whereby the ring 18 is moved axially relative to the ring 27; as the valve is opened the disc 14 forms folds 44 between adjacent pairs of ribs. The ribs 15 terminate short of the outer periphery of the disc so that in the fully closed position the controlled fluid acts on the disc and so forces its periphery into sealing contact with the duct 10. Excessive pressure flexes the disc 14 sufficiently to cause the ribs to contact the duct.

Abstract: 1348474 Washing drainage bags &c MOTALA VERKSTAD AB and LANDSTINGENS INKOPSCENTRAL 9 March 1972 [10 March 1971 27 Aug 1971] 11098/72 Heading A4N [Also in Division B8] Apparatus for emptying, rinsing and disinfecting drainage bags 3 containing body fluids comprises a closable treatment chamber or basin 8 provided with a waste outlet, a collecting basket 1 adapted to carry a plurality of bags 3 supported within the chamber, puncturing-devices 12 arranged in the chamber, and means (not shown) for supplying rinsing liquid and disinfectant to the chamber. The collecting basket comprises a plurality of compartments 2, each of which accommodates a bag 3 secured to a holder 4 attached to a shaft (5), Fig.1 (not shown), according to the quantity of fluid in the bags, an arm 6 in conjunction with a spring 7 providing positional locking of the bags. The basket, which may be provided with a graduated scale, is situated in the chamber which is provided with a lid 9 and a plurality of knives 12 corresponding to the number of compartments in the basket. A knife holder 11, normally supporting a grid-like structure (not shown), is attached to a structure 13 for support thereof. Closure of the lid 9 causes pressure to be exerted on handles (14) of the basket, and the bottom portions of the drainage bags are punctured by the knives. The rinsing mechanism of the chamber then starts and a programmed cycle is then effected during which the bags are disinfected. Alternatively, the closing of the lid may cause subsequent operation of the knives during which rinsing and disinfecting occurs. Springs 15 are arranged to support the basket and to be compressed when the lid is closed thus preventing puncturing of the bags before the lid is closed. An alternative embodiment, Figs.5, 6 (not shown) features scissor-like devices (17), arranged in the basket and mounted in holders (18), and a stirrup (21) for clipping the bags. Closure of the lid 9 causes depression of the stirrup in guides (22) and subsequent actuation of link arms (16) to cause rotation of cutting members (19) around shafts (23). Springs (24) return the members (19) to their original position after clipping.

Abstract: 472,705. Weighing-apparatus. FITZPATRICK, H. J. (Maatschappij van Berkel's Patent N. V.) April 18, 1936, No. 11157. [Class 143] In a weighing-apparatus mounted on wheels disposed on spaced axes, one or more of the wheels may be positively moved up and down relatively to the apparatus to render it mobile or non-mobile. As shown in connection with a platform machine, the pair of wheels 4 at one end is mounted on the foot of a dashpot cylinder 6. The piston rod 8 of the dashpot is attached to a bracket 10, the undersurface of which co-operates with cam rollers 15 on a handle 14 pivoted on the cylinder. By rotating the handle from the full line position shown, the machine is rocked about the axis of the wheels 3, the holding projections 5 are raised from the ground and the machine becomes entirely supported on the wheels 3, 4 in readiness for moving. The reverse movement of the handle lowers the machine on to the projections 5, the dashpot cushioning the movement. The cylinder is loosely mounted so as to be capable of rotation on its vertical axis thus permitting a swivelling movement of the wheels 4 by manipulation of the handle 14.

Title: Improvements relating to aircraft alighting gear

Abstract: 696,548. Liquid - spring shock absorbers. DOWTY EQUIPMENT, Ltd. May 12, 1952 [May 11, 1951], No. 11200/51. Addition to 695,061. Class 108 (iii). The liquid spring claimed in the parent Specification is modified by the provision of a remotely-operated valve 44 (Fig. 1), which when closed prevents passage of liquid through the plunger head 8 and thus enables the head 8 to function as a jack piston. The head 8 comprises a sleeve 8a threaded to the plunger 6, and rigidly carries a piston 26 formed with damping orifices 28 and a port 29 for a one-way valve 31. An auxiliary piston 32 is slidably mounted on the head 8. The piston 32 has an internal step 35 which is engageable with an abutment 36 integral with the head 8, and a skirt 37 which is engageable with the annular piston 7. The valve 44 is carried by a rod 45 having a bevelled head 51, protruding from the outer end of the plunger and engageable by a conical-headed screw 52. The valve 44 may thus be urged, by rotation of the screw 52, to close a port 39 against the action of a spring 48. In operation, when the spring is to be extended, when the aircraft is airborne, liquid is injected through the connector 14 and acts on the area of the plunger 6 only, as in the parent Specification. In this case liquid passes through the valve 31, ports 40, ports 38, valve 39, ports 42, and slots 43 in the step 35, to the upper side of the head 8. When it is necessary to extend the spring against the static load of the aircraft on the ground, the valve 48 is closed by the screw 52 and pressure applied at the connector 14 thus acts both on the plunger 6 and on the piston 32. The latter picks up the plunger 6 by engagement of the step 35 and abutment 36. The pressure acting to extend the plunger is thus effective over the full cross-sectional area of the chamber 4 until the upper end of the skirt 37 is arrested by the piston 7 in engagement with the upper end of the chamber 4. This limitation of further movement of the piston 32 before full extension of the plunger 6 has occurred, is to ensure a correct degree of pressurization of the fully-extended spring. In a modified construction (Fig. 3) the valve 44 is carried by a piston 54 which is actuated by liquid pressure applied at will. Specifications 560,047 and 560,068, [Group XXXIV], also are referred to.
