Title: Improvements relating to pneumatically actuated mechanism for feeding bars through the fixed headstocks of lathes
IPC: B23B13/02
Filed: 1949-12-09
Abstract: 668,353. Lathe details. HUGHES, Ltd., G. H., and CRAWSHAW, A. L. Dec. 11, 1950 [Dec. 9, 1949], No. 31623/49. Class 83 (iii). A pneumatic mechanism for feeding bar stock in lathes and of the type in which a piston within a cylinder engages one end of the bar to move it towards the lathe headstock, is characterized in that the cylinder coacts with a valve in the pneumatic supply line so that the valve is opened when the cylinder is in the feeding position and is automatically closed when the cylinder is displaced therefrom. The cylinder 6 having a piston 5 engaging the stock 1 through an anti-friction bearing 4 and block 3, has a flexible fluid line 11 and may be swung from the position shown to the opposite end of an arcuate slot 7. The position in the drawing is that for loading bar-stock into the cylinder; when the cylinder is brought to the opposite end of the slot it is in line with the lathe spindle and is thus in position to feed the stock. In the latter position a normally closed valve 17 in the air pressure line is opened by the cylinder pushing against a projection 15a. The latter also forms part of a valve 15 normally open to the atmosphere at 16 but closed when the cylinder operates the projection 15a. Opening of valve 17 also allows air pressure to pass through a channel 14 to a piston 22 which operates a latch 23 adapted' to engage a hole 24 in the cylinder to retain it securely in the operative position. A reduction valve 12 is included in the circuit to the piston 5 and the inlet air is controlled by a hand cock 19.

Abstract: 750,227. Television pick-up tubes. BRITISH BROADCASTING CORPORATION. March 15, 1954 [Dec. 13, 1952], No. 31651/52. Class 39 (1). [Also in Group XL (c)] In a television camera image-orthicon with a secondary electron collecting screen 16 on the photo-cathode side of the storage target 15, the potential of the target screen is varied automatically in dependence upon and in the same sense as variations in the intensity of the brighter part or parts of the scene being televised. The screen 16 is biased to a potential at which it collects all secondary electrons up to a given optimum operating level of intensity of illumination, but if this level is exceeded the potential is automatically varied for the screen to continue to collect all secondary electrons. A control circuit between the tube output and the screen 16 comprises amplifier 26, direct current restorer 28, 29, 30, rectifier 31, and storage circuit 32, 33. The tube output is derived from the electron multiplier 231. Specification 750,225 is referred to.

Abstract: 1,109,136. Hydraulic presses. L. REXROTH. 26 July, 1965 [24 July, 1964], No. 31693/65. Heading B5F. Pressure fluid supplied at 12 passes via channels 11, 13, 18, 19 to a recess 8 in a piston 2 and forces the piston 2 to the left, thereby drawing fluid into a cylinder 1 through passages 28, 29, 30 from a reservoir (not shown). When pressure in 8 exceeds the pressure of a spring 28<SP>1</SP> a control piston 17 is forced to the right thereby closing passage 29 and allowing pressure fluid from 8 to flow through a bore 24 and channel 30 to the annular face of piston 2. Pressure fluid now acts over the whole of the area of the piston 2. Return movement of piston 2 may be effected by a spring (not shown). In a modification (Fig. 2, not shown) an auxiliary piston (36) co-operates with the spring (28<SP>1</SP>) urging the control piston 17 to the left, whereby the pressure needed to move the piston 17 to the right can be adjusted.

Abstract: 894,964. Prestressed concrete. CUFFLIN HOLDINGS Ltd. Oct. 6, 1959 [Oct. 6, 1958], No. 31879/58. Class 20(4) A device for transmitting stress from the tensioning wires to the concrete of post-tensioned prestressed concrete structures, comprises a steel tubular element provided with means for applying compression in an axial direction to concrete immediately surrounding the tube, the tubular element being encircled by a helically wound steel wire element secured thereto and radially spaced therefrom. In one embodiment the tubular element comprises an intermediate cylindrical portion 15, Fig. 4, a frusto-conical outer end portion 12 against which abuts a bearing plate 27 having conical anchorage orifices 28 for the tensioning wires, and a frusto-conical inner portion 14 which engages a tube 24 which forms a duct 25 through the concrete 26, which tube may be withdrawn after the concrete has hardened. The helical steel wire element 16 has its end portions turned inwardly to engage the tubular element 11 and be welded thereto. A flange plate 13 is welded to the extreme outer end of the tubular element 11. In another embodiment intended for use with a single tensioning wire having a conical gripping element mounted thereon, the tubular element 11, Fig. 5, of the device is ragged or serrated at 30.

Title: Improvements in or relating to percussion fuses for projectiles
IPC: F42C15/24
Filed: 1932-11-11
Abstract: 398,052. Projectile fuzes. BRANDT, E. W., 101, Boulevard Murat, Paris. Nov. 11, 1932, No. 31925. Convention date, Nov. 30, 1931. [Class 9 (i).] A percussion fuze comprises a primer carrier which is so arranged that it can move forward in its housing, by inertia, on the projectile being retarded by air resistance, and can thus reach an enlarged annular space in the vicinity of the striker, into which space locking members normally screening the striker can pass so that the fuze is then armed ; when in engagement with the walls of the annular space, the locking members serve to prevent rearward movement of the primer carrier when impact occurs. In a bore 2 in the fuze casing 1, a very light striker 3 is provided at the front end, held forward by a spring 4. The spring also presses rearwardly a tube 6 in which a primer carrier 9 is located, the latter being normally held at the rear end of the tube 6 by balls 13, retained in holes in the tube by a spring-pressed inertia sleeve 16. The cylindrical bore 7<1> of the tube 6 opens into a wider portion 7 at the end adjacent to the firing pin 3. Balls 11 or the like are housed above the primer 10 in holes in the walls of the member 9, and are retained in the position shown in Fig. 1, in which they form a barrier between the primer and the firing pin 3, so long as the primer carrier 9 remains in the narrower portion 71 of the bore of the member 6. When the projectile is fired, the sleeve 16 sets back, and the balls 13 escape from their housings, releasing the primer carrier 9. This creeps forward during the flight of the projectile, and reaches the position shown in Fig. 4 by the time the projectile is at a safe distance from the gun. The balls 11 then pass out into the wide space 7, leaving the firing pin a clear passage to the primer 10. Ignition occurs either when the striker 3 is driven in by direct action, or by forward movement of the tube 6, due to its momentum, or by both these actions. Instantaneous or delayed firing on impact is effected at will by providing two passages 20, 21, leading to the detonator 23, the passage 20 containing a time-fuze composition 24, and the passage 21 a cock 25 which can be set to close the passage when delayed action is desired. Fig. 12 shows a modification in which the primer carrier 9 slides in the bore 2 of the fuze casing, the movable housing 6 being dispensed with. The device for locking the member 9 in the rearward position and the arrangement of the spring 4.are also modified as shown.

The brake pad 12 is so located relative to the centre of the piston that the latter point B is aft of the radial centre line of the pad by an amount x (assuming the direction of rotation of the disc to be as indicated in Fig. 1) and the centre of the piston is offset a radial distance b from the centre of area of the pad. The amount of set arcuately (X) is sub. stantially equal to the thickness of the brake pad (e) multiplied by the coefficient of friction between the pad and the disc (Á). Using polar co-ordinates the distance b may be determined.

The negative high tension terminal is connected to the cathode 12 through the secondary of the audio-frequency transformer 13. The primary of 13 is connected to the output of amplifier 16 which is fed from the audio-frequency oscillator 19. Coil 20 and condensers 21, 22 determine the audio-frequency. With key 23 open the frequency may be 3200 cycles and with the key closed, 1000. A filter is provided in the receiver so that only the 1000 cycles signal is audible. Telegraphic keying is carried out by opening and closing key 23 ; consequently a keyed 1000 cycle note is heard at the receiver. Specification 433,427 is referred to.
