Patent GB-230338-A (GB)
Abstract: 230,338. Green, W. July 10, 1924. Grounding aerials.-An aerial lead-in device is combined with a plug-and-socket connector for the receiving or transmitting set in such a way that the pressure, or pull applied when connecting or disconnecting the set moves the socket member and so operates switch mechanism to make or break the connections from the respective aerial and earth wires to the socket, and to break or make a direct connection between the aerial and earth wires. As shown in the Figure, the plug g connected to the set is inserted in the socket member e which is arranged for a limited sliding movement in a tube a. The sockets are connected by wires f, f<1> to contact members i, i<1> which co-operate with spring contacts d, d<1> connected to aerial and earth terminals c, c<1>. In the position shown, connection is made from the aerial and earth wires to the set. When the plug is removed, the member e slides to the right and brings a conducting disc h between the springs d, d<1> thus earthing the aerial directly. The tube a is screwed into a plate n which forms a cover for the switch casing b. The casing b is secured by screws to the outside of a window frame.

Abstract: 353,710. Indicating liquid-level. HOEHNE, B., 157, Falkenbergerstrasse, Weissensee, Berlin. July 31, 1930, No. 23094. Convention date, July 31, 1929. [Classes 106 (v) and 123 (i).] In a liquid-level indicator, particularly for the fuel tank of a motor vehicle, a column of the liquid depending on the level is transferred either by suction or pressure into a measuring vessel. A tube 2 extending to the bottom of the tank is provided with a disc valve 5 which seats upward, and is protected by a strainer 7. An inner tube 3 is provided with a lateral orifice 8, and the annular space is connected to the air at 10. The tube 3 is connected by a flexible pipe 11 to a measuring container 1 which may be connected either at its upper part by a passage 15, or at its lower part by an orifice 20 and passage 17, to a pipe 12 connected to a source of suction such as the motor of the vehicle. The alternative connection is made by a disc valve 13 operated by a turn-button 18. When the pipe 12 is connected to the passage 17, atmospheric pressure exists in the tubes 2, 3, since even when suction exists in the pipe 12 the suction exerted through the very small opening 20 is neutralized by air pressure through the openings 14, 15. If the pipe 12 is then connected to the upper part of the chamber 1 by turning the valve 13, the suction first closes the valve 5, trapping a column of fuel, and then draws the liquid through pipe 15 into the vessel 1 where its height can be read by means of a floating disc 21 or by means of dye 23 which colours the liquid as it enters. To remove the liquid fuel from the vessel 1, the pipe inlet 24 may be arranged at the bottom of the vessel and not as illustrated. If air is admitted by rotating the valve 13, the liquid returns to the tank 4 by gravity. Alternatively, the valve 13 may be set so that the pipe 12 is connected to the passage 17, whereby the liquid is drawn toward the induction pipe of the engine.

Filed: 1971-04-19
Abstract: 1321146 EHT supplies GTE SYLVANIA Inc 19 April 1971 [9 March 1970] 23543/71 Heading H2F [Also in Division H4] A voltage related to the high-voltage employed in a television receiver is derived from the horizontal output stage 25 (Fig. 1) via a network 33 and utilized, when it exceeds a threshold level set by diode 41, to shift the frequency of the horizontal oscillator 21 to outside the range of synchronization so that the resulting distortion of the displayed picture provides a warning to the viewer that the high-voltage has increased to a level at which X-ray radiation may emanate from the receiver. The network 33 includes a voltage dependent resistor VDR 35 the logarithmic characteristic of which results in emphasized voltage variations appearing at the junction of VDR 35 and resistor 33 and when such voltage variations exceed the threshold level of diode 41 the control effect on the horizontal oscillator 21 is arranged to be such that synchronism cannot be restored by the viewer by adjustment of the horizontal "hold" control 22. During normal operation synchronization is effected by AFC network 19 which compares the received synch. signals with signals derived from output stage 25.

A screw and nut mechanism such as for actuating windows &c. of automotive vehicles, comprises a motor-driven screw 12, Fig. 1, having a single or multiple thread rolled thereon, a non- rotatable axially-movable nut 14 having on its inner surface a number of spaced annular grooves, and a loose sheet metal cage 18 having therein a number of slots 26 each housing a ball which registers with the helical and annular grooves respectively of the screw and nut members. The slots 26 allow axial movement of the balls to compensate for inaccuracies of manufacture, which thus need not be to close tolerances. In a modification providing a " freewheel " the cage has at each end a pair of axially-projecting ears 38, Fig. 6, which co-operate with two pins 34 in the screw 12 so that after a desired amount of axial movement of nut and cage one of the ears contacts a pin 34 and the screw and cage rotate together without moving the nut. Each pair of ears comprises two axial faces 40, spaced 180 degrees apart, and two inclined faces of a pitch the same as or greater than that of the thread to avoid jamming. In further modifications the cage has at each end a single ear which may co-operate with a single pin, with two pins spaced 180 degrees apart, or with the two ends of a single' pin passing diametrically through the screw.

Title: Data processing systems

Abstract: 1343375 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 19 May 1972 [25 Aug 1971] 23558/72 Heading G4A Each of two processors accesses data from its own buffer store 15 and shares main storage with the other processor, and the two processors communicate with each other to ensure that each processor can only access the most up to date value of each data item. In the embodiment shown, each section 33 of buffer 15 stores a block (page) of data and the corresponding register 34 of a directory 27 stores the segment (book) address of that block together with control bits V, S, F which indicate that the associated block is valid or not valid, has been stored into by the corresponding processor since its transfer from main storage, and that the other processor has transferred the same block to its buffer from main storage. Buffer 15 and directory 27 are simultaneously accessed by the block address of the requested data via OR 36, the segment address obtained from directory 27 being compared at 39 with the segment address of the requested data and gate 41 determining the validity of the accessed block. Assuming the block to be valid, a fetch request opens gate 45 to transfer the block from buffer 15 to the associated (local) processor, whereas a store request initiates the following operations. If buffer 15 of the local processor contains the only copy of the requested block (F = O) gate 55 is opened to store into the accessed block and the corresponding S bit in directory 27 is set (gate 89). If the remote processor also has a copy of the requested block in its buffer (local F = 1) the requested address is broadcast on bus 29 to access the buffer and directory of the remote processor, reset the V bit in its directory if it is on and in either case (remote V = 0 or 1) reset the relevant F bit in the local directory 27, store into the accessed block and set the relevant S bit as above. Main storage transfer (local V = 0).-A replacement algorithm selects a block in the local buffer 15 to be replaced and its address is broadcast over bus 29. If the block being replaced is valid and has an S bit = 1 the block is transferred to main storage and the S bit is reset in directory 27. The broadcast address causes the other processor to determine the status of the requested block in its directory and perform the following operations. (1) If the block is not valid, the relevant F bit in the directory of the requesting processor is reset. (2) If the block is valid and S = 1, the block is written in main storage and S is reset, then, or otherwise, the F bits in both directories are set for a fetch operation or the valid bit for the block in the remote processor's directory is reset. Finally, for (1) or (2) the requested block is transferred from main storage to the buffer of the requesting processor and the fetch/store request executed from buffer. The Specification briefly discusses other types of store operation i.e. "store through" and "store wherever" and modifications using fewer control bits.
