Patent GB-757166-A (GB)
Abstract: 757,166. Turning-gear.BENDIX AVIATION CORPORATION. Aug. 31, 1954 [Sept. 2, 1953], No. 25274/54. Class 7(5) Construction. In an engine starter drive including a driving overrunning clutchmember 6 slidably journalled on a smooth .portion 4 of the power shaft 1, and a friction clutch having driving and driven plates 9 and 11 splined, respectively, to the shaft 1 and to a coupling sleeve 8 splined on the clutch member 6, the clutch is operatively connected to a pinion 19 adapted to move into and out of mesh with an engine gear 22. The power shaft 1 has a splined part 3 the junction of which with the smooth portion 4 is formed by a shoulder 5 whilst the friction clutch 9, 11, is loaded by springs 16, the compression of which is limited by a thrust washer 17 on the shoulder 5. Adjustment of the maximum torque to be transmitted by the friction clutch is effected by varying the thickness of the washer 17; the clutch plates are maintained under initial pressure by a lock ring 18. The pinion 19 is slidably journalled upon a further reduced portion of the power shaft and is attached to a barrel 23 that has slots accommodating the lugs 28 of a nut 27 threaded on a screwshaft 31 which is slidably journalled on the shaft portion 4 and formed with teeth 32 coacting with. the teeth 7 of the clutch member 6; a meshing spring 33 disposed between a thrust ring 34 on the pinion hub and a thimble 35 abutting the nut 27 keeps the pinion extended relative to the barrel. The meshed position of the drive is defined by a stop 36 on the power shaft, a thrust washer 38 being interposed between the nut 27 and stop which also serves to transmit to the screwshaft 31 the pressure of a spring 39 which loads the overrunning clutch 7, 32. A centrifugally-releasable spring-loaded detent 41 in the nut 27 co-operates with a shoulder 43 in the screwshaft when the pinion is meshed with the engine gear 22; the detent engages a shoulder 44 on the screwshaft to maintain the drive in the idle position. Operation. In operation the torque capacity of the friction clutch is increased when, after meshing of the pinion 19 with the gear 22, the screwshaft 31 and clutch member 6 are forced leftwardly by screwjack action until the clutch slips when member 6 abuts washer 17. Should tooth abutment occur the spring 33 is compressed and increases the loading of the friction clutch until sufficient torque is built up to effect indexing. When the engine starts the detent 41 prevents immediate demeshing of the pinion but the release of the cranking torque permits rightward movement of the screwshaft against the spring 39 to enable the clutch 7, 32 to overrun.

Title: Improvements in error correction devices
IPC: H03M13/15
Filed: 1979-01-15
Abstract: A codeword generated by a feedback shift register and received after transmission over a noisy channel is stored in a shift register 5 as a set of analogue voltages (or digitised versions thereof). With binary values initially represented as equal voltages of opposite polarity, the value Ii in each shift register stage represents, according to its sign, the likelihood of the corresponding codeword bit being 0 or 1 &cirf&  The likelihood values for a given bit bi and two further bits bi+s, bi+t, with which the bit bi has a known parity relationship, are used to compute (6) an enhanced likelihood value Ii' for re-insertion into the shift register 5 or insertion into another shift register for subsequent processing. All values Ii are thus treated in turn for N</=i</=o and the process repeated for a different pair of s and t, (though all pairs s,t could be run through for bi before passing on to the next bit). The entire process is repeated for as many times as is necessary for the values Ii' of at least the data bits to exceed a pre- set threshold. <IMAGE>

Abstract: A terminal display has a central processor unit (CPU) 21, a central memory 28, video display logic 35, video monitor 36, video display interface 34, and various bus drivers, transceivers, clock driver and clocks. The video display interface 34 includes means for making the CPU 21 think that an external I/O (input or output) device has made a data channel interrupt request (DCH. INT.), means for recognizing that the CPU 21 has acknowledged the DCH. INT., means for generating control signals to prevent the CPU 21 accessing memory 28, and means causing data to be fetched from memory 28 for display.

Filed: 1979-06-15
Abstract: A water resistant ground burst simulator for use in military training ejects a readily dispersable powder or liquid in the air to simulate explosion of ground burst munitions, such as mines or shells. The simulator comprises a cylindrical open-ended casing 1 in which a frangible water- proof bag 2 containing a chemical agent i.e. powder or liquid is placed.

Title: Energy-providing drink suitable for diabetics
IPC: A23L2/60
Filed: 1979-10-05
Abstract: The invention comprises an aqueous energy-rich soft drink preparation. The energy-providing components are glycerol and fructose in specific combinations; namely, 2.5% to 40% of the former and 1% to 15% of the latter (both by weight). Preferred amounts are 5% to 20% of glycerol and 2% to 10% of fructose. These substances, metabolized without the participation of insulin, make the compositions particularly suitable for diabetics, though also of value in any other energy-requiring situation. The energy boost supplied rapidly by the glycerol is prolonged by the more slowly-metabolized fructose. The remaining ingredients are preferably but not exclusively to be natural or nature-identical. Further components of nutritional or medicinal value such as vitamins, are advantageously included. Where natural fruit juices are incorporated their amounts should be limited to a maximum of 10% in diabetic preparations.
