Abstract: 1285986 Shearing ETCO Inc 27 Oct 1969 52600/69 Heading B3W An explosively-operated cable cutter comprises a blade housing 14, which has a cablereceiving recess 46a, a fixed blade 48 and a movable blade 35 and is screwed to a piston housing 13, a firing mechanism 12 pivoted to the piston housing, a piston grip 11 and trigger 18. The blades are bevelled away from their cutting edges 35a, 48a at 35b, 48b and have thickened portions 35d, 48d. A buffer spring 39 between a freely-sliding collar 37 and a coupling 41 joining the piston housing to the blade housing returns the piston after a cutting stroke. To cock the blade 35, a handle 55 (Fig. 5) is pulled rearwards, a tongue 57 entering a slot 58 in the blade housing 14 and engaging a shoulder 35e on the blade 35 to move it to its rearmost position. The handle is returned by spring 60. The trigger 18 is biased by a spring 21 so that a sear 18a engages a shoulder 23 on a plunger 24 when the plunger is pulled rearwardly by means of a knob 29. When the trigger is pulled a spring urges the plunger forward, a firing pin 27 striking a cartridge (not shown) in chamber 50 and forcing the piston rod 34 and blade 35 forwardly. Gases from the explosion are exhausted through a chamber (43), Fig. 1 (not shown). A member 30 straddling the portion 17 of the handle prevents rotation of the knob 29 and a bar 66 prevents inadvertent release of the plunger 24. A shield 67 and guards 68 and 69 are provided. Pivoting of the firing mechanism 12 away from the piston housing (Figs. 3 and 4, not shown) causes partial ejection of the spent cartridge.

Filed: 1970-12-10
Abstract: 1292070 Digital data stores INTERNATIONAL BUSINESS MACHINES CORP 10 Dec 1970 [29 Dec 1969] 58651/70 Heading G4C In a system for linking a central processing unit (CPU) and a number of data stores (e.g. discs) there is provided a control unit which concurrently executes control commands in different ones of a number of command registers. The control commands, together with data transfer commands which require a shorter time for execution than do control commands, cause the stores to be accessed. Upon detection of a data transfer command in an accessed command register concurrent execution of any other command is prevented. The control unit is generally similar to that described in Specification 1,179,613. The control unit includes two address registers, each associated with respective programmes stored in the unit. In a first mode of operation the registers are operated alternately by respective clock pulse trains which are of the same frequency and out of phase. Communication between the CPU and the control unit memory takes place via a second of the address registers. Under the control of sets of instructions from the CPU the control unit develops control commands which are placed in the command registers and which select the discs, and the tracks on those discs, containing the locations into/ from which data is to be written/read. Each location is preceded by an identifier block comprising an address and a key (e.g. a Social Security number). When an identifier block is read the control unit switches to a second mode of operation in which the clock pulse trains are combined and feed only the first address register. As the second address register now receives no clock pulses communication with the CPU ceases. The programme associated with the first register now compares the key in the detected identifier block with a key defined by the control command currently and exclusively being executed. If the comparison shows that the location is not the required one the control unit reverts to the first mode until an identifier block is again detected. On the other hand if the location is that required the data included in the appropriate instruction set previously received from the CPU is read in to the store, or data read from the store in the instruction so dictates. At the completion of read in/out the control unit reverts to the first mode.
