Title: Synchronous signal isolating circuit
Inventor: FUJII EIJIYU
IPC: H04N5/08
Filed: 1980-01-07
Abstract: PURPOSE:To obtain a synchronous signal having a short lackig period, by discontinuing the peak clamping action for the drop-out period of a video signal and at the same time inhibiting the production of a synchronous signal for the drop-out period and for several H periods following the drop-out period. CONSTITUTION:For the video signal applied to the input terminal 1, the tip of the synchronous signal is fixed at a certain potential by the peak clamping circuit 2'. The drop-out pulse having the same duration as the duration of the drop-out is applied to the circuit 2' from the input terminal 4' of the drop-out pulse, and the clamping action is discontinued for the period of the drop-out. The output signal of the circuit 2' is applied to the voltage comparator 3, and the synchronous signal is isolated. This synchronous signal is applied to the gate circuit 4 for elimination of the noise, thus obtaining the noiseless sysnchronous signal through the output terminal 5. The pulse duration expanding circuit 12 expands the duration of the drop-out pulse for several horizontal periods H to apply it to the circuit 4, thus eliminating the noise produced in that period.

Title: Improvements in or relating to computer systems
IPC: G06F9/38
Filed: 1970-01-01
Abstract: 1,235,638. Computers. INTERNATIONAL BUSINESS MACHINES CORP. 1 Jan., 1970 [6 Jan., 1969], No. 130/70. Heading G4A. A computer system transfers work data between a work register and a data store location specified by address data as modified by index data, both address data and index data coming from the work register, and increments the index data. Local-storage work registers each contain a data field, an index field and an address field. An instruction for an execute operation specifies two of the registers to supply operands and one to receive the result, and contains a tag bit for each. If this tag bit for an operand is 1, then after gating the operand to the arithmetic logic unit, another operand is loaded into the register from the main store location specified by the sum of the address and index fields from the register and the index field is incremented and restored, these reload and increment operations being omitted if the tag bit is 0. If the tag bit for the result is 1, then after gating the result to the work register, the result is stored in the main memory with addressing and incrementing as above, these store and increment operations being omitted if the tag bit is 0. Thus an instruction can be executed repeatedly using different operands. Two-bit tags could be used to permit selection of a load or store operation. The address fields could select index registers providing the addresses.

Abstract: 546,691. Guided skip hoists. GROSSMITH, G. W., SARGENT, T., and STRACHAN & HENSHAW Ltd. Jan. 14, 1941, No. 520. [Class 78 (iii)] A skip hoist comprises a rail track 1 extending first in a vertical direction or at a steep incline and thereafter at a slight incline along a line of hoppers 2, a skip 4 mounted on a carriage 3 travelling on said track being first raised, then traversed along the line of hoppers, and finally discharged into any pre-selected hopper, the skip being caused to rotate relatively to its carriage 3 to operate a time control switch whereby the carriage is caused to stop, reverse, and return to its filling point. The carriage 3 is hauled along the track by a winch 23 and rope or ropes 14, guard rails 15 being provided to prevent the carriage leaving the track. The skip is pivoted on trunnions 5 on the carriage and is so balanced whether full or empty that a stop 7 on the skip normally abuts a stop 8 on the carriage. As the skip is hauled along the line of hoppers a horn 9 on the skip is adapted to engage a stop 10 over one of the hoppers, if this stop has been raised from an inoperative position to the position shown in Fig. 2, so that the skip is rotated about the trunnions 5 and discharges into the selected hopper. At the same time the forward movement of the carriage 3 is automatically stopped by means of a pulley 16 on the skip ; as the skip rotates this pulley engages a cord or chain 17 and pulls the arm 18 of a reversing limit or time switch 19 to stop the winch 23. After a time interval determined by the switch 19, the carriage 3 runs down the track 1 under the influence of gravity, the start being assisted by the self-righting torque of the skip, due to the horn 9 pressing against the stop 10. The switch 19 is reset by a weighted arm 22. The stops 10 are provided with weighted arms 12 which tend to maintain them in either of their two positions as determined by stops 13, and they may be operated manually or by remote electrical, hydraulic or pneumatic control means.

Abstract: 590,832. Feedwater supply systems &c. BRITISH ARCA REGULATORS, Ltd., and LINDSAY, T. Jan. 10, 1945, No. 880. [Class 123 (ii)] [Also in Group XXVI] The pressure of supply of fluid to several vessels in common, for example, feed water to a bank of boilers a<1>, a<2>...., is regulated so as to exceed slightly the highest pressure existing in the highest pressure boiler by a valve h in the steam supply pipe of the turbine d driving the feed pump c. The valve h is connected to a diaphragm 1 which is located within a chamber k and is subjected on one side to the action of a spring i, tending to open the valve, and on the other side to a variable fluid pressure in a pipe line j, m terminating in a leak port n, the said leak port being controlled by a checking member o mounted on a pivoted lever p. This lever p is acted upon by an adjustable spring q which normally rocks it in a direction to open the leak port n, with consequent opening of the valve h; movement of the lever is also influenced by the pressure in the common feed pipe b and the highest boiler pressure respectively acting through bellows s, u on opposite sides of the lever pivot, as shown. The highest boiler pressure is transmitted to the bellows u through a differential manometer, in the form of small bore pipes g which ascend from a partitioned tank f containing mercury e and are connected at their upper ends each to a boiler, and through a pipe t, containing water or oil, between said mercury tank and bellows.
