Abstract: 428,626. Speed indicators. MITCHELL, F., 8, St. Aubyns, Hove, Sussex. Nov. 22,1933, No. 32543. [Class 106 (iii)] Apparatus for indicating the number of times one or more predetermined speeds of a motor vehicle have been reached, and also for indicating, when a car comes to a quick stop, at what speed it was travelling just before, comprises a sealed box X mounted for rotation with the road-wheel and containing a sliding weight W or a pivoted weight A which when thrown outwards by centrifugal force against regulated spring pressure operates by its pro. jection W<2> successive trip mechanisms or pawl devices A<11>, A<12>, A<13> for moving, one tooth at a time, indicator wheels E displaying the number of times the respective speed limits have been exceeded. The resistance offered successively by the springs S<1>, S<2> and G, G<6> during the movement of the weights W, A is regulated by cams S<5>, G<9>. Sudden movements of the weights are damped by the use of oil dashpot and other devices. The driving spring of the clockwork for the indicator wheels may be kept wound by a centrifugally-operated weight, and this clock mechanism may indicate at a window 0 the number of hours the car has been running. By retarding the return movement of the weight, and providing a brake which presses on the balance wheel of the clock when the car stops, the weight will be retained in its speedindicating position, should the car be stopped after an accident, this position being indicated by a red spot A<3> moved by the weight. The device may be used in conjunction with a speed indicator of the type referred to in Specification 26429/08, [Class 106].

Title: Improvements in or relating to shift registers
IPC: G11C19/00
Filed: 1964-08-11
Abstract: 1,010,587. Shift registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1964 [Aug. 29, 1963], No. 32654/64. Heading G4C. A shift register includes a plurality of cells each including a plurality of logic blocks connected in a loop in which an information bit is circulated, each logic block being supplied with one of a plurality of cyclic energization signals, logic blocks in each cell being connected directly to logic blocks in other cells, both of two blocks between which a bit is being transferred being energized by the cyclic energization signals during the transfer, and there being gating means adapted to determine the blocks between which the bit is transferred. Fig. 2 shows one cell (the Rth) of the register. Control signals READ IN, SHIFT 1, SHIFT 2, SHIFT 4 are applied to all cells from a common set of control triggers (Fig. 1, not shown) to cause each cell to accept a bit on a corresponding IN line 21 from outside the register or on lines R-1, R-2, R-4 from the cells one, two or four cells lower in the register, respectively. Each cell comprises majority logic blocks 61 to 64, 71 to 74 each with a threshold of two, blocks 61 to 64 serving for circulating a bit in the cell and blocks 71 to 74 serving in connection with transfer between cells. Each logic block may only produce an output when gated by a pulse of a respective clock pulse train PHASE 1, 2, 3 or 4 (common to all cells). The trains overlap as shown in Fig. 3. One cycle of the clock pulse trains (one pulse from each train) is required to read bits into the cells from outside, or to shift all bits along by from one to seven cells depending on the combination of shift control signals applied. Shifts along by one, two and four cells are done on direct lines between cells but other length shifts are via one or more intermediate cells. By provision of extra phases, logic blocks etc. shifts by greater numbers of cells can be accomplished.

Title: Improvements in or relating to voltage controlling means in systems for supplying electric consuming devices
IPC: G05F1/52
Filed: 1927-12-05
Abstract: 309,209. Graham Amplion, Ltd., and Turner, P. K. Dec. 5, 1927. Supplying consuming devices.-In systems in which thermionic valves or other discharge devices 1 - - 3 are supplied in parallel through a voltage-reducing, fixed; series resistance R, a neon lamp N or other discharge device of similar characteristics is connected in shunt to the valves 1 - - 3 and in series with the resistance Rand is arranged so that the critical voltage at which it commences to conduct is slightly above the voltage normally across it, the lamp normally not taking current. When the voltage across the valves 1 - - 3 rises due to the failure, say, of the valve 3 and to the consequent reduction in current in the resistance R, the lamp N lights and conducts the surplus current and thereafter steadily maintains a safe voltage across the valves. The resistance R does not produce appreciable smoothing and may normally carry only the total current to the valves 1 - - 3 as shown, or may form part of a potential-dividing high resistance across the source S, the connection Z to the valves being then connected to one tapping and the positive pole of the lamp N to a second tapping near to, and above or below, the first. In an amplifier, a final valve 4 may be connected across the source S. The lighting of the lamp may form a warning particularly when the amplifier is remote from the lamp. The Provisional Specification describes also an arrangement with a casing having a window for observation of the lamp. Specification 254,422 is referred' to.

Filed: 1955-11-18
Abstract: 816,507. Lubricating. AIR PRODUCTS Inc. Nov. 18, 1955, No. 33010/55. Class 12 (3). Apparatus for extracting energy from an elastic fluid such as a gas comprises a turbine 1, or other elastic fluid expansion engine, operable to remove energy from the fluid upon expansion of the latter, and a pump 6 coupled thereto and having an inlet 10 and an outlet 8 for an hydraulic fluid, e.g. a lubricant, which is circulated in a closed system including a cooler &c. 9. In the construction shown, a gas turbine having a gas inlet 2 and a gas outlet 3 has its rotor 25 carried on a vertical shaft 27 which passes through a radial bearing 4 and rests upon a thrust bearing 5. The lower end of the shaft is connected to a pump rotor carrying impeller blades 53. The pump is adapted to discharge lubricant under pressure through the outlet 8 and the cooler 9 and back through the pump inlet 10. Part of the lubricant from the outlet 8 is supplied to a connection 11 leading to the bearing 4 and part is supplied to a connection 12 leading to the thrust bearing 5. Lubricant supplied to these bearings is drawn off through a connection 13 into a reservoir 14 which is provided at the top with a receptacle 16 provided with a small leak 17. The outlet 8 of the pump is connected to the receptacle through a valve 18 whereby, during the operation of the apparatus, the receptacle 16 may be supplied with lubricant in quantity greater than that which can leak through the opening 17. The gas turbine is enclosed by a cover-plate 19 and a seal is provided between the housing and the rotor 25, comprising a carbon ring 28 carried on a flexible metallic bellows 29. The shaft 27 below the rotor passes through a sleeve 31 which fits close to, but not in tight frictional engagement with, the shaft 27, and is carried on a plate 32 closing an opening in the turbine housing 1. Below the plate 32 is a block 34 of thermal insulating material surrounded by a sleeve 36. Thermal insulating material 40 surrounds the entire turbine housing. Leakage of gas down the outside of the shaft 27 is prevented by the lubricant passed to the bearings 4 and 5. In order that the inlet pressure required by the pump may be high enough, lubricant is supplied to the pump through a connection 58 with a tip 59 located within the entrance to a restriction 57 from the pipe 10. When the apparatus is in use lubricant entering the top of the reservoir 14 will gradually fill the receptacle 16, the level in the lower part of the reservoir falling to the line 62, so that the space 44 below the radial bearing 4 will be kept drained of lubricant which would otherwise be beaten into froth.
