Title: Fuse for projectiles
IPC: F42C1/02
Filed: 1921-12-02
Abstract: 172,326. RÚmondy, L. E. Dec. 4, 1920, [Convention date]. Projectile fuzes.-An impact fuze is made with a forwardly projecting member 5, Fig. 1, which is arrested suddenly by the target, and a momentum pellet or percussion cap 7, which is carried by the member 5 but is free to continue its forward motion after the member 5 is arrested. This relative motion causes the cap 7 to strike a pin 6 secured to the member 5. The relative position of the cap and firing-pin may be reversed, the cap being secured to the member 5 and the firing- pin constituting the movable pellet. Before impact, the member 5 is held in place by a shear wire 10, or otherwise and the momentum pellet by a spring 9 or otherwise. The member 5 may be further locked by a split collar disposed underneath its head 5<a> and removed (1) before the projectile is discharged, or (2) at the moment of discharge by means, for example, of a rope connecting the collar to an aircraft from which the projectile is dropped, or (3) after discharge from a gun, by centrifugal force when the grip of the head 5<a> on the collar due to inertia during the period of acceleration ceases. The percussion cap may be mounted in a thimble 8 and may be covered by a disc of paper or metal, according to the degree of sensitiveness desired. A delay patch 24 and an intermediate detonating charge cr relay 25 may be provided behind the percussion cap, the delay patch and relay being combined as in Fig. 8, or separate from each other. The forward end of the projecting member 5 may be detachable and may be made of light material such as wcod or aluminium. A felt or other resilient washer may be inserted at 11 behind a shoulder on the member 5. The joint 27 between the member 5 and the body of the fuze may be sealed with wax or tin. Old fuzes may be converted by replacing their working parts according to this invention, the body of the fuze being alterel where necessary.

Title: Improvements in or relating to electrical musical instruments
Inventor: SCHREIBER ERNST
IPC: G10H1/18
Filed: 1955-11-15
Abstract: 803,292. Electrophonic musical instruments. VEB WERK FUR FERNMELDEWESEN. Nov. 15, 1955, No. 32611/55. Class 88 (2). In a keyboard instrument, each key is associated with a control valve such as 36 common to all the generators such as 8-14 of the harmonics of the corresponding note, the generator outputs being ineffective when the valve is conductive and effective when the valve is cut off. The circuit for one key in relation to bus-bars for the 1<SP>1</SP>-16<SP>1</SP> registers is shown, and the operation will be described with respect to the 16<SP>1</SP> register, the other registers functioning in a similar manner at the same time. The keycontact 37 is normally closed so that valve 36 and rectifier 29 connected to the bus-bar are conductive. Rectifier 29 is in parallel with resistance 16 and so makes this part of voltage divider 15, 16 of low resistance so that the output of tone generator 8 does not appear effectively on the bus-bar. When the key is depressed, contact 37 opens and valve 36 is biased beyond cut-off, so that rectifier 29 becomes of high resistance and the output of generator 8 becomes effective on the 16<SP>1</SP> bus-bar. Resistors 38, 39 and condenser 40 determine the overall attack and decay, and further resistors 42-46 and condensers 54-58 individual to the busbars ensure a slower response from the lower harmonics.

Title: A turning and stopping indicator for vehicles
IPC: B60Q1/34
Filed: 1921-12-06
Abstract: 194,367. Goold, L. W., (American Auto Signal Co., Inc.). Dec. 6,1921. Road-traffic signals on vehicles; monogrammic signals.-A stopping and turning signal for road vehicles comprises a number of lamps arranged in compartments behind a translucent screen, the compartments being formed as sections which, when selectively illuminated, combine to form the words " LEFT," " RITE," or " STOP." Construction of indicator. The translucent screen 3, Fig. 7, has cross-hatched cuts or mouldings on its inner surface, and preferably is painted red on its outer surface which may be sand-blasted to complete the diffusion of the light. The lamps 19 are inserted in sockets in a false bottom 17, and are adapted to make contact with resilient plungers 13 carried by an insulating plate 5. Each plunger 13 is hollow and contains a spring 12, Fig. 8, extending into a hollow bolt 7 in which the plunger slides, the bolt being clamped in position by nuts 8, 8, and attached to an electric conductor 9. Reflecting partitions 22, Fig. 6, are so arranged as to divide the face of the indicator into sections containing lamps, and these sections can be classified into seven groups such that the sections in one of the groups are required for each of the words " LEFT," " RITE," and " STOP," while those in a different group are required for " LEFT " and " RITE " only, and so on. Four groups have to be illuminated simultaneously to produce any one of the three words. Construction of controlling switch, Figs. 11 and 12. The illumination is controlled by a switch having a wiper pivoted on the bolt 28 which is connected to a source of current. The wiper consists of two conducting strips 30, 31, the lower of which is extended to form a handle 32, and carries four spring plunger contacts 33 cooperating with four at a time of the studs 35. Twelve such studs are mounted, six above and six below the wiper, in insulating plates 26, 27, and are each connected to one or other of the seven groups of lamps described above. Hence there are three operative positions for the wiper, in each of which it causes the illumination of four groups of lamps to set up one of the three words. For the two intermediate angular positions of the wiper, which are inoperative, plates 40 are provided and these, as well as certain of the studs 35, are recessed to receive a plunger 33 and lock the switch in position. A tell tale lamp 42 indicates whether the apparatus is effective.

Filed: 1971-07-12
Abstract: 1362223 Hinged closures SOC D'EXPLOITATION DES BREVETS NEIMAN 12 July 1971 [15 July 1970 2 March 1971] 32664/71 Heading B8T [Also in Division E2] A vacuum or electromagnetically operated fuel tank filler cap 7 is hinged at 8 to a plastics collar 2 on the filler pipe 1. An electromagnetic coil 4 is located in an annular groove in the collar 2 and a magnetic metal ring 6 rests on springs 5, the ring 6 being formed with an opening 32 engaged by stop pin 14 carried by lock-bolt 12 which slides within a bearing member of cap 7. A spring 16 urges stop pin 14 to its closed position adjacent the hole 32 formed in the ring 6. Lock bolt 12 is operated by eccentric member 13 rigidly connected to a control knob 10 so that, when the electromagnet 4 is actuated from a remote switch through lead 31, the magnet pulls down ring 6 freeing stop pin 14 and enabling knob 10 to be turned and thereby to withdraw lock-bolt 12. On completion of the filling operation, the switch is operated to de-energize the electromagnet, and springs 5 push up the ring 6 to receive the stop pin 14, the spring 16 returning the latch 12. In a modification, Fig. 7 (not shown), an electro-magnet moves a yoke armature, to which is secured a lever (120) with catch portion (121), against a spring (118) to free a strip (123) from the catch portion, thus releasing the cap (108). On discontinuing magnetic action, the cap (108) may be closed by moving it against spring (109) and camming the strip (123) past catch portion 121 against the action of spring 118. Again, Fig. 11 (not shown), passing an electric current through the electromagnet (139) causes plunger core (137) to be pulled against spring (138) and causes lock-bolt (136) to move backwards, disengaging bolt clasp (132) enabling the opening of cap (128) under action of spring (135). After switching off current to the magnet, the cap (128) is pressed down manually and lock bolt (136), due to its slantwise cut, retracts under the reaction of the upper edge of bolt clasp (132), projecting again under action of spring (138) to lock the cap. The closure may be unlocked, Fig. 13, by using a manually-operated valve (154), Fig. 14 (not shown), to connect a duct 153 to a source of vacuum, e.g. the engine induction manifold. When the cover is closed, a spring-loaded ball 145 is held under the lip of a member 148 and bears against bolt-clasp 157 formed in a ring 150. On applying a vacuum through the duct 153, the ring 150 is drawn downwards against the force of springs 149 thereby freeing the ball 145 which passes over the lip of member 148 when the cap is raised manually.

Title: Digital data recording systems
IPC: G06F11/10
Filed: 1973-07-12
Abstract: 1403672 Digital data recording systems INTERNATIONAL BUSINESS MACHINES CORP 12 July 1973 [21 Aug 1972] 33253/73 Heading G4C Digital data is recorded in groups of data in error-correcting code. The number and positions of the errors in a group is determined on reading. The recording is also monitored to determine where errors may occur in the group by checking certain recording criteria, e.g. read-out signal energy. If the positions of the predicted and actual errors do not match, or if there are more actual errors than can be corrected by the code, an error indication is given. The embodiment described uses multi-track magnetic tape 15 and each group includes a digit in each track. The data read by head 16 passes to monitor 19 and detector 18. For each group monitor 19 indicates which tracks may contain an error. Detector 18 also indicates tracks in error, e.g. by considering the energy or phase shift of the signal read. Detector 18 feeds decoder 21 via deskewing unit 20. Decoder 21 detects the presence of combinations or values of bits inadmissable in the code. The signals from monitor 19, detector 18, and decoder 21 pass to comparator 25 via OR gates 30 and represent predicted track errors. Decoder 21 feeds error detector 22 which outputs corrected data, where possible, and indicates whether there are k or fewer actual errors (k being the maximum number correctable by the code) and pointers indicating which tracks may be in error. Comparator 24 may comprise an assembly of gates (Fig. 2, not shown) which provides an error signal on line 37 if for each track the actual error is not matched by a predicted error. If the errors do match a signal is passed to gate 27 which is open if there are k or fewer actual errors. The error signal on line 37, or the absence of an output from AND gate 27, is detected by unit 11 which may, for example, initiate error recovery procedures (not described)
