Title: An improved differential braking device, particularly suitable for wheels of aeroplanes and other vehicles
IPC: B64C25/48
Filed: 1933-04-19
Abstract: 412,734. Steering vehicles by differential braking. MESSIER, Y. L., 179, Boulevard Brune, Paris. April 19, 1933, No. 11435. Convention date, April 19, 1932. [Class 79 (ii).] In a fluid-pressure braking system, particularly applicable to aeroplanes and other vehicles, in which fluid from a pump P first applies the brakes and in which means are provided to facilitate subsequent differential application of the brakes, two distinct circuits are provided; between the pump and the brakes the first d<1>, d<2> leads directly to and is open during " taking-up " slack in the brakes, whilst the second d<3> is closed whilst the first circuit is opened, but is opened automatically after a predetermined pressure has been reached. In one form, movement of a lever causes fluid to pass from a cylinder P into brake cylinders F<1>, F2, to take up clearance of the shoes, through valves s<1>, s<2>, held open against springs by a lever v controlled by a spring-pressed piston p situated in a valve chamber E. Rise of pressure in the valve chamber E depresses piston p allowing valves s<1> and s<2> to close and valve s<3> to open to prevent further flow of fluid through the circuit d<1>, d<2> and to supply fluid to a cylinder Q to operate piston N, the piston rod l of which is under the pilot's control to bear adjustably on a pivoted link B, the ends of which are connected to pistons P<1>, P<2> which thus differentially supply the brake cylinders F<1>, F<2> to apply the brakes. The piston rod b may be operated directly or indirectly. Specification 341,007 is referred to.

Title: Improvements relating to attachments for telephone instruments
IPC: H04M1/04
Filed: 1926-05-01
Abstract: 272,014. Schein, H. May 1, 1926. No Patent granted (Sealing fee not paid). Supporting.-In a telephone instrument having a holder f for the receiver c, the switch hook d is held in its depressed position, when the instrument is not in use, by means of a lever l pivoted at n to a band-clip m adjustable on the pillar b. The lower end of the lever is formed as a hook q by means of which the lever can be operated to cause its clip portion p to be engaged with or disengaged from the hook d. Stops r, s, Fig. 6, are formed on the lever l and boss t of the pivot n respectively. The holder f and arm e are formed from a single piece of wire connected at its inner end by a ball and socket joint i, j, Fig. 5, to a band clip g adjustable on the pillar b.

Title: Improvements in or relating to ammunition and projectiles for bomb-throwers
IPC: F42B5/18
Filed: 1941-09-10
Abstract: 575,860. Cartridges and projectiles ; ordnance. LENDER, M. Sept. 10, 1941, No. 11622. [Classes 9 (i), 9 (ii) and 92 (ii)] The propellant charge for projectiles fired from open-end recoilless guns has such quick - burning characteristics as to be wholly consumed before the projectile leaves the muzzle of a short discharge tube or gun, and is contained in a container of cup or part-spherical shape. The propellant may be of cordite type augmented by black powder dust, aluminium powder and baryta, the ingredients being arranged in layers. A hemispherical charge A applied directly to the base of a projectile B is shown in Fig. 5. Fig. 2 shows a projectile having a charge cavity A<2> of spherical formation with a flared outlet A<3>, and also inclined passages'D, whereby rdtation is set up by the issuing gases. In a modified form, the cavity A<2> may be filled with ordinary propellant and a quick-burning charge, such as that of Fig. 5, is attached to the projectile base, the internal propellant being ignited after the projectile has left the discharge tube A<1> and acting as a rocket charge in flight. 'A glass bottle or a tin F, Fig. 4, may be fired from the gun by interposing between the hemispherical charge A and the bottle or the like a disc E of wood, pasteboard or metal, and a rubber wad H or a layer of adhesive, the whole being enclosed in a paper or like combustible sack. The disc E may have oblique holes G filled with the propellant powder to impart spin to the projectile through the friction of the wad H or the adhesive. A firing mechanism (not claimed), actuated by a trigger L, is shown in Fig. 5, the striker J being pivoted in a recess O in the wall of the tube, and re-cocked on discharge by the blast of the propellant gases. A bundle of the discharge tubes, for use on aircraft, may be assembled in a frame which is lowered on a parallel linkage from a housed position in the fuselage or wing to a discharge position therebelow. This also is not claimed. Specification 12732/08, [Class 9], is referred to.

Abstract: 788,654. Thermal switches; protective cut-out systems; control of A.C. motors. ELLENBERGER & POENSGEN GES. April 22, 1954, No. 11625/54. Classes 38 (3) and 38 (5). [Also in Group XXXV] A switch comprises a bimetal strip 6 carrying a contact 5 and connected to a terminal 7, a heater 8 connected to a separate terminal 9 and to the contact 5, and a fixed contact 2 connected to a terminal 4. Preferably and as shown, the bimetal carries a back contact 5<SP>2</SP> which cooperates with a contact 9<SP>2</SP> connected to terminal 9 so as to short-circuit the heater 8 in order to prevent overheating of the bimetal. The switch may be used in a variety of circuits, e.g. in Fig. 2, a motor starting winding 37 may be cut out a certain time after closing a main switch 39, leaving the main winding 38 energized. In Fig. 4, shunt windings 44, 45 are respectively connected to terminals 9, 7 of the switch which cuts out the motor on overload. In Fig. 5 (not shown), shunt wound starting windings are controlled by one such switch and overload control of the shunt wound main windings is given by a second such switch. Alternatively, in Fig. 6 (not shown), series wound starting windings are controlled similarly, and the overload control of the series wound main windings is given by a known switch.

Abstract: 554,613. Crimping fibres. AMERICAN VISCOSE CORPORATION. Aug. 19, 1942, No. 11652. Convention date, Oct. 4, 1941. [Class 120 (iii)] Staple fibres are crimped by imparting a longitudinal velocity to a bundle thereof and causing the moving bundle to be thrown substantially endwise against an obstruction. As shown the fibres are cut by a knife 5 from filamentary material led through a radial channel 4 in a revolving disc 2 and the cut bundles are thrown onto the periphery 10 of a revolving drum with an end of the bundle impinging against a flange 19 on the drum; the crimped fibres pass down a duct 15 and an air jet 18 may be used to blow off any fibres sticking to the drum. In a modification the flanged drum is disposed closely adjacent the knife 5 and any fibres sticking to the drum are removed therefrom by a doctor blade.

Clutches, ratchet and friction.-A one-way clutch comprises a. pair of segmental friction shoes or pawls 11 adapted to be jammed between an internal annular friction surface 3 and a pair of cams or segmental ramps 9 upon a central shaft H. Compression springs 13 are arranged between the adjacent ends of the shoes 11 by which initial friction with the surface 3 is produced. The shoes 11 have recesses 10 on their outer peripheries at their middles so that the shoes may bend and a tighter grip be obtained. Escape of oil from between the gripping surfaces may be permitted by providing recesses 14, 15 in the shoes and in the annular surface respectively.

[Class 40 (iii).] Distorted signals are reshaped and repeated, independently of their relative strength, bymeans comprising transformers of the impulse coil type acting upon polarized unbiased electromagnetic relays. The signals received from cable 11 are passed through a shaping network 12 of the kind described in Specification 248,823, [Class 40 (iii), Telegraphs, Electric], and through a low-current valve and shaping networks 13, 16, 15, 18 to oppositely biased transformer coils 21, 22 whose cores have high permeability for small magnetizing fields and are readily saturated, as described in Specification 312,904, [Class 40 (iii). Telegraphs, Electric]. The impulses applied to the coils 21, 22 are shown at b, and the intensities at which the cores of 21, 22 respectively become saturated are shown at b21, b22 respectively. The biases are therefore such that positive and negative input impulses respectively affect coils 21 and 22, producing pairs of opposite output impulses as at c and at d respectively. These impulses are passed on by a two-stage large-current push-pull amplifier 24, 26 to the pair of polarized unbiased relays 32, 33 whose armatures are thereby set to give outputs e, f respectively. The combined output at terminals 34 is as shown at g.
