IPC: E21B1/34
Filed: 1970-07-06
Abstract: 1295142 Drilling machines G A BERGMAN 6 July 1970 [7 July 1969] 32544/70 Heading B3C [Also in Division B4] A percussive tool comprises an impact piston 48, the head of which is slidable within a hollow drive piston 42, and a crank drive for reciprocating the drive piston 42 within cylinder 50. The drive piston 42 during its reciprocation causes, via air cushions formed between the impact piston head and the end walls of the drive piston, reciprocations of the impact piston. The drive piston 42 upon its upward stroke sucks air via one-way valves (not shown) and ports 62 into the space below the drive piston, and upon its downward stroke compresses and then expels air from that space via one-way valve 66 into the interior of casing 56 and then via a bore (not shown) in the tool bit 60 to the bore hole. As illustrated, the crank drive, which comprises a shaft 22, eccentric 34 and connecting rod 34, is driven by an I.C. engine. Alternatively, an electric motor may be used to drive the shaft 22. The tool bit 60 may be rotated by means not shown.

Abstract: 1295631 Projectile fuzes BOLKOW GmbH 14 May 1968 [6 July 1967] 22944/68 Heading F3A An electrical detonator 4 is connected to contacts 1a, 1b situated on the exterior of a projectile casing and connectible temporarily to an external electrical supply 10. When the supply 10 is connected it charges a condenser 2 through a switching spark gap 3, e.g. a glow switch. The supply voltage 22 is chosen to be only slightly greater than the strike voltage of the gap 3 to ensure that the condenser voltage 20 remains below the strike voltage and thus prevent discharge of the condenser should the contacts 1a, 1b become accidentally shortcircuited. A switch 5 closed by a clockwork mechanism 6 causes the condenser 2 to discharge through the detonator 4 after a time delay. In a modification (Fig. 4, not shown) the voltage of the supply 10 is slightly less than the strike voltage of the spark gap 3 but has a number of periodically occurring voltage peaks of a value greater than the strike voltage. However, only a single voltage peak is necessary since the gap 3 continues to conduct once it has been struck. In a further modification. Figs. 5, 6, the circuit of the supply 10 includes a resistance 12 and capacitor 11, the spark gap 3 becoming conducting each time the difference of the voltages 26 and 20 across the capacitor 11 and 2 becomes equal to the strike voltage 21. Thus the capacitor 2 is charged in steps and the charging may be stopped after a desired number of steps by a counting operation. To ensure that the voltage 20 does not exceed the strike voltage 21 the magnitude of the supply voltage 22 or the number of charging steps are limited accordingly. The mechanism 6 of Fig. 1 is omitted and instead the switch 5 is closed by impact of the projectile so that the capacitor 2 charges a capacitor 8 through a resistor 7. When the voltage across capacitor 8 equals the strike voltage of a further spark gap 9, the detonator 4 operates.

Claimed separately are methods of making such an assembly, either (a) by moulding it in a single piece of magnetic material, or (b) by placing the bridges on a common bar of an auxiliary matrix reproducing the lay-out of the matrix of address and bit conductors and backed by a magnetic sheet, attaching a strip bearing the inscription to the bridges, then removing the assembly of bridges from the auxiliary matrix. The auxiliary matrix of (b) has horizontal and vertical bars corresponding to the conductors of the memory matrix forming square depressions between them into which legs of the bridges fit. The strip may be part of a transparent plastics sheet which is then glued to the bridges, after which the sheet is removed and cut up into strips each holding the bridges for one character. The memory matrix itself may use a magnetic sheet on which the conductors are deposited or laid e.g. in grooves or positioned by notches at the edges of the matrix. Two memory matrices may be formed on opposite faces of a support, or a plurality of such pairs of matrices may be joined like the pages of a book with the bit conductors running continuously from page to page.

Title: Encoders
IPC: H03M1/00
Filed: 1970-08-24
Abstract: 1318775 Analogue/digital converters PLESSEY TELECOMMUNICATIONS RESEARCH Ltd 24 Nov 1971 [24 Aug 1970] 40661/70 Heading G4H In an analogue-n bit digital converter in which a first coding operation derives from the analogue input the r most significant bits of the digital signal and the second coding operation derives the s least significant bits (r + s > n), the least significant bit(s) of the r bits and the most significant bit(s) of the s bits are combined to derive the n bit output signal. In the embodiment of Fig. 2, in which an 11 bit output is obtained from two coding operations each deriving 6 bits, with switches 23, 30 in the position shown, a bias signal of 5 units is subtracted from the sampled input signal before it is fed to a coder 24 to derive the six most significant bits. Switches 23, 40 are then changed over and the contents of the coder 24 are read into a store 26 connected to output logic 33 and a decoder 29 (for example a ladder network). The resulting analogue signals from the decoder is subtracted from the input signal, the difference signal being amplified by 2<SP>5</SP> before being fed to decoder 24 to derive the six least significant bits. Subsequently the output logic 33 adds the least significant bit of the first coding operation and the most significant bit of the second coding operation to obtain the required output. In a second embodiment (Fig. 3) a bias voltage of 2<SP>5</SP> is subtracted from the input signal after it has been sampled in a sampling circuit 42, the resulting signal being fed to a first coder 44 to derive the most significant bits which are then fed to a store 47 connected to a decoder 49 and output logic 48. The output of the decoder is subtracted from the output of a second sampling circuit 45 receiving the sampled input from the first circuit 42, the difference signal being amplified by 2<SP>5</SP> before being fed to a second coder 51 to derive the least significant bits. As in the embodiment of Fig. 2 the output logic 48 combines the 12 bits to produce an 11 bit signal. A delay 53 is included to enable sampling circuit 45 to read in the contents of the sampling circuit 42 before a new sample is taken. This results in fine decoding of one sample occurring simultaneously with the coarse encoding of the succeeding sample. Diodes 40 (Fig. 2), 43 (Fig. 3) are included to prevent one of the two coding operations having an effect on the other. The apparatus described reduces errors due to inaccuracy in the coders. Modifications: (1) The apparatus may be extended to more than two coding operations; (2) the bias of 2<SP>5</SP> may alternatively be applied in the opposite sense to the amplified difference in the second coding operation; (3) the number of bits derived in the two coding operations may be different; (4) the fine and coarse coding operations may overlap by more than one bit and (5) if the signals are slowly varying the sample and hold circuits may be dispensed with.
