Title: Improvements in or relating to hydraulic fluid pumps or motors
IPC: F04C15/00
Filed: 1965-12-22
Abstract: 1,132,050. Rotary pumps and motors. TRW Inc. Dec.22, 1965[Aug.20, 1965], No.54388/65. Heading F1F. A fluid-pressure seal pack in a rotary pump or motor, particularly a gear pump, comprises a bimetal wear-plate 48, Fig. 1, a gasket 50 and a sealing web 52 with the gasket and sealing web received in a recess groove system 42 in the lower half 14 of the pump housing 10. The wear-plate 48 on its face 48d, Fig. 3, adjacent the gears 20 is formed with a shallow groove 48e and on its opposite face with a similar but somewhat shorter and wider groove 45h communicating with the groove 48e by a port 48L through the plate positioned on the minor axis of the plate opposite to a similarly positioned port 48k. The gasket 50, Fig.2, is divided into pressure zones A, B, C 1 , C 2  by suitable webs, so that the zone A is connected to the pump inlet port 38 through the port 48k and the zone B to the pump discharge port 38<SP>1</SP> through the port 48L. The zones C 1 , C 2  are also connected to the pump discharge port via the groove 45h to seal the wear plate 48 against the gears 20. With the zones A, B, C 1 , C 2  symmetrically disposed the removal of the plate 48 and the turning of it through 180 degrees will permit reverse flow through the pump. The zones B, C 1  and C 2  will then communicate with the port 38 which will now be the discharge port and the zone A with the port 38<SP>1</SP> which will now be the inlet port. The groove 48e permits the distribution of pressure-fluid at discharge pressure about the gears 20 and also to substantially balance the pressure on both sides of the wear-plate. The invention may be applied to pumps and motors including rotors having outwardly sliding vanes.

Title: Method and apparatus for generating a traveling display
IPC: G09G1/04
Filed: 1972-05-24
Abstract: 1395922 Control of displays BUNKER RAMO CORP 24 May 1972 [8 Sept 1971] 24515/72 Heading G4H [Also in Division H4] Apparatus for generating a travelling display on a cathode ray tube C.R.T. 10, Fig. 1, incorporates means for advancing information across the display at a rate which varies with the rate at which input data is received. Information displayed on the C.R.T. 10 is cyclically refreshed with a raster pattern made up of lines of characters formed by selectively intensifying seven index points on each of five strokes (Fig. 3): synchronizing pulses 12 control three ramp generators for stroke generation, line generation (horizontal retrace), and line spacing and frame retrace respectively, the horizontal retrace pulses being supplied to C.R.T. 10 via a variable delay 14. Data is fed via an input buffer register 32 to a random access memory 24, each line being stored in a separate segment (Fig. 4), in each of which positions 4-51 store data being displayed whereas positions 1-3, 52-56 store buffer characters for updating the display. A detector 51 assigns incoming data to the appropriate segment, and a detector 36 increments a counter 48 which indicates the address in 24 at which the next incoming character is to be stored (character 2, in Fig. 4). A character counter 50 stores the address in 24 of the first character being displayed (4, in Fig. 4); a stroke counter 50 counts modulo 7 to increment the character counter and to control delay 14. On the occurrence of the first frame sync. pulse FR1, the count (2) in 48 is fed to a counter 66 and a buffer counter 62 is set to the value 8; the counts (4, 2) in 50 and 66 are compared at 68, a "no match" signal 70 opening a gate 72 so that subsequent FR pulses can increment 66 and decrement 62. When 66 and 50 agree, the count in 62 indicates the number of new buffer characters (6, in Fig. 4), and is passed through a gate 80 by a "match" signal 78 to a detector circuit 82-85, where it sets a "shift 1" or a "shift 2" flip-flop. The output 98 or 126 from the particular set flip-flop is fed back to enable one of gates 100 or 128 so that pulses FR can increment the stroke counter by 1 or 2. The horizontal retrace pulse passing through 14 is delayed by a number of strokes equal to the stroke count 106 (2 strokes for data of Fig. 4): while the retrace pulse is being delayed, a clock 22 continues to read out from memory 24, so that memory 24 becomes out of phase with the delay: thus an effective stroke shift operation is performed, the display shifts to the left (here by 2 strokes) and the first two strokes (Fig. 4 data) of the first buffer character 2 are displayed. The above process continues until all the buffer characters have been displayed, the display lines shifting to the left all the while.

Patent GB-462181-A (GB)
Title: Improvements in the manufacture and production of unsaturated aliphatic carboxylic acid nitriles
Filed: 1935-09-03
Abstract: Unsaturated nitriles are obtained from saturated halogenated aliphatic nitriles containing up to six carbon atoms by treating the latter at a raised temperature with basic substances of a basicity not exceeding that of barium hydroxide and/or with catalysts which promote the elimination of hydrogen halide.  The process may be effected by converting a saturated aliphatic carboxylic acid containing up to six carbon atoms into its nitrile by reaction with ammonia in the presence of a dehydrating catalyst, halogenating the nitrile, and treating the halogenated nitrile as described above; alternatively, the acid may first be halogenated and the halogenated acid then treated with ammonia, in which event the halogenated nitrile is formed as an intermediate product and then undergoes further reaction, as described above. In the examples, (1) monochlorinated isobutyronitrile is led at 400--450 DEG  C. under reduced pressure over titanium dioxide, this yielding methacrylic nitrile; the same product is obtainable by heating monochlorisobutyronitrile with ammonia to 80--100 DEG  C. in a closed vessel, or by passing monochlorisobutyronitrile and ammonia at 200--250 DEG  C. over silica gel; (2) isobutyric acid is monochlorinated, and the product is led with ammonia at 380 DEG  C. over silica gel; methacrylic nitrile is again obtained; (3) isobutyric acid and ammonia are passed at 380 DEG  C. over silica gel, and the isobutyronitrile so obtained is monochlorinated; the chlorination product is then treated as in example 1.  Other specified starting materials are halogen derivatives of propionitrile, butyronitrile and valeronitrile.  Other specified basic reagents are calcium and magnesium oxides.  Other specified catalysts for eliminating hydrogen halide are aluminium oxide, p barium chloride and active carbon.  The Specification as open to inspection under Sect. 91 refers generally to the production of unsaturated aliphatic or cycloaliphatic nitriles by eliminating hydrogen halide from halogenated saturated aliphatic or cycloaliphatic nitriles. Halogen derivatives of capric, myristic, palmitic, montanic and naphthenic acid nitriles are additional specified starting materials, and alkali oxides are additional specified reagents for the elimination of hydrogen halide.  A further example is given in which isobutyronitrile is chlorinated and the product is fractionated to recover monochlorisobutyronitrile, which is led at 440 DEG  C. over calcium or magnesium oxide; methacrylic nitrile is obtained; by adding fresh oxide as required, the process may be effected continuously.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1420997 Data processing PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 May 1973 [27 May 1972] 24832/73 Heading G4A A processor PROC (Fig. 3), normally controlled by pulses from a clock distributed by AND 01-04, is clocked at a slower rate after an error signal FT is generated. As described the error signal sets a bi-stable F to its " 1 " state to disable an AND gate 10 and hence AND gates 01-04. After an interval determined by a delay DL, bi-stable R is also set to its one state so that at a clock pulse 4 from the clock AND gate 13 is enabled to reset bi-stable F. The reset signal is also applied to reset to their zero states bi-stable (T0-T2, Fig. 4, not shown) in a control unit CMT which is such that OR gates OR1-OR4 are then sequentially enabled by output signals 1SL-4SL from the control unit, one gate being enabled for every five clock pulses from the clock. Information which has been transferred from a slower main store to a fast store in the processor may be erased in response to the error signal, the information being re-fetched.

Filed: 1936-09-17
Abstract: 477,714. Prepayment mechanism for meters. LANDIS & GYR AKT.-GES. Sept. 17, 1936, No. 25282. Convention date, Sept. 21, 1935. [Class 27] The supply switch of a prepayment electricity meter comprises contacts 27 adapted to be bridged by a contact drum 25 on a shaft 1, a catch 23 coacting with an arm 3 on the shaft to hold the switch closed against the action of a spring 2. Secured to the shaft 20 of the catch 23 is an arm 15 loaded by a spring 21 to bias the catch to its locking position. A roller 30 on the arm 15 is adapted to be struck by a cam 16 on a shaft 8, subject to the torque of a weighted arm 14, and controlled by engagement of a finger 19 with a releasing element 17 connected with the quantity mechanism. In the closed circuit position shown, the weighted arm 14 has only a slight overbalance, and the finger 19 contacts lightly with the element 17. When prepayment is exhausted, the element 17 releases the finger 19 allowing the arm 14 to rotate the shaft 8 until the cam 16 strikes the arm 15, which disengages the catch 23, so that the arm 3 is moved by the spring 2 to break the circuit. The arm 14 is checked in its fall by engagement of a pin 11 with a bar 7 on the arm 3. When further prepayment is made, a finger 29, on a shaft 28 turned by the coin mechanism, moves back the arm 3 : the bar 7 releases the weighted arm 14 which turns the shaft 8 to bring the teeth of a mutilated pinion 9 thereon into mesh with a rack 4 on the arm 3, so that the shaft 8 is then rotated clockwise to re-engage the finger 19 with the element 17, the arm 3 being finally locked by the catch 23 with the drum 25 bridging the contacts 27.
