Abstract: 1,041,563. Valves. R. TRIST CONTROLS Ltd. Nov. 16, 1962 [Nov. 27, 1961], No. 42338/61. Addition to 877,445. Heading F2V. [Also in Divisions F4 and G1] In a modification to the plant of the parent Specification 877,445, the rotary valve is replaced by a reciprocating slide valve so connected to a one-way device that once the reciprocating movement of the valve is started the valve must pass through positions in which a chamber and a liquid leg are blown down before the valve can be returned to its starting position. In the position shown in Fig. 1, the blow-down port 4 is closed and the steam and liquid legs 3 and 2 are in communication with one another. On initial movement of the valve member 5 by hand wheel 11 the steam and liquid legs 3, 2 are connected to the port 4 through grooves 10. Continued movement of the valve member 5 shuts the steam leg 3 leaving the liquid leg 2 connected to the port 4 through the grooves 10. Further movement of the valve member 5 to the end of its travel shuts the liquid leg 2 and opens the steam leg 3 to the port 4. On the return movement of the valve member 5 the cycle is reversed. A spring- biased pivotally mounted pawl 13 co-operating with the interior walls 19, 20 21 and ratchet teeth 24 prevent the wheel 11 being returned to its starting position until the cycle of the wheel 11 in one direction or the other has been completed.

Title: Wide dynamic range amplifier system with slew rate control
IPC: H03M1/00
Filed: 1974-10-04
Abstract: 1458137 Automatic gain control TEXACO DEVELOPMENT CORP 4 Oct 1974 [12 Nov 1973] 43042/74 Heading H4R In an amplifier system having cascaded fixed gain amplifiers A, B 1 -B 4  whose outputs are successively sampled by gates 1-S 1  to 1-S 5  and compared at G, H, I with a reference V to hold as the system output that sample for which the output satisfies most closely a predetermined relationship with the reference (e.g. so that seismic signals may be digitally recorded at the optimum level), the overall gain setting thus determined is modified by a circuit 25, detailed in Fig. 2, when the rate of change of output level exceeds a predetermined maximum V 1 . This prevents the recorder being overloaded by signals which when sampled are passing through zero but with a large gradient. Sampling of each of n channels by scanner 5 is controlled by sync. pulses E 7 . When the output E 15  of comparator 33 in circuit 25 is high, indicating that V 1  has been exceeded, counter 38 is caused to decrement at clock rate 50 to establish a code E 2 -E 6  by which certain gates 15-19 are enabled to allow passage of sampling signals from scanner 5 to the sampling gates and thereby reduce the gain setting. Similarly, a low output from the comparator 33 is inverted 39 to increment the counter and increase gain setting but only when a further gate 40 is opened by comparator 45 when the system output V 0  is less than a reference V 2  representing the ratio of full scale output to unit amplifier gain. No count is performed when the output V 0  exceeds the ratio but the maximum rate of change of output is not reached. An indication of which amplifier is operative is also recorded to give a floating point code as in Specification 1,266,710 (Division G4).

Abstract: 1354581 Driving record carriers; indicators XEROX CORP 17 Sept 1971 [21 Sept 1970] 43466/71 Heading G5R  A tape transport system 10 indicates when a predetermined amount of tape 12 is left on a supply reel 20 by determining when the increasing angular velocity of the supply reel 20 attains a certain value, and comprises a light source 32, one or more apertures 28 or specular surfaces (60), Fig. 3 (not shown), on the spindle 16 which supports the supply reel 20, and a phototransistor 30, whereby pulses are generated whose frequency is proportional to the angular velocity of the spindle 16; a monostable 44 which generates a reference signal of predetermined duration; and a NAND gate 42 which provides an output signal when the time separation of the pulses is less than the duration of the reference signal. The output signal energizes a lamp 54 via a resettable latch 56. The pulses may also be generated by a Hall effect device. Pulses from the phototransistor 30 are first shaped to a square form, e.g. by a monostable 38. The shaped pulsesare passed through a bi-stable 46 to the monostable 44 which is thus triggered at the end of alternate shaped pulses. The duration of the reference pulses from the monostable 44 is adjustable. The NAND gate 42 compares the reference pulses with the shaped pulses for coincidence. By providing duplicate circuits beyond the wave shaper (68), Fig. 3 (not shown), in which the monostables (70), (72) have different operating times, two different points on the tape may be indicated.

Title: Process of making cyanoalkylsilanes
IPC: C08G77/26
Filed: 1960-12-19
Abstract: Cyanolkylsilanes in which the cyano group is connected to the silicon atom through at least 2 carbon atoms are prepared by reacting an alkene nitrile with a silane HSiX3, where X is a hydrolysable group other than hydrogen, using as catalyst a silylamine of the formula: R14-y Si (NHR)y where R1 is a monovalent hydrocarbon or alkoxy group, R is hydrogen, alkyl, aryl, chloroalkyl or chloroaryl and y is 1 to 4. Specified catalysts are <FORM:0948757/C3/1> The amount of heavies produced may be reduced by adding a silane RSiHX2; this silane does not react with the nitrile.  A polymerisation inhibitor may also be added, e.g. 2,6-di-tert-butyl-4-methylphenyl, hydroquinone, tert-butyl catechol and tert-butyl-4-methylphenol. Examples of nitriles are acrylonitrile, methacrylonitrile, crotononitrile, allyl and methallyl cyanides, 1-cyano-4-pentene, 1-cyano-3-butene and 1-cyano-1-hexene.  The hydrolysable groups in the starting silane may be halo, alkoxy, aryloxy and acetoxy.  The cyanoalkylchlorosilanes may be esterified to the corresponding cyanoalkylalkoxysilanes which can be hydrogenated to the aminoalkylalkoxysilanes.  The catalyst may be removed by esterification or hydrolysis and removing the low-boiling silalkoxide or silanol.  The examples describe the preparation of beta-cyanoethyl trichlorosilane.  Specification 847,805 is referred to.

[Also in Division F2] A control for starting and selecting the duration of drive from an electric motor to a web drive mechanism in a recording-apparatus comprises a control shaft 19 which is slid axially to start the drive and rotated to select the duration of drive. A hub 2 fast with the shaft 19, a gear box 1 and pinion 11 slide axially with the shaft 19 against the bias of a spring 6. The pinion 11 slides into mesh with two pinions in the transmission between the electric motor and web driving mechanism and thus completes the transmission therebetween. Rotation of the shaft 19 which is permitted by a slip coupling between the shaft and pinion 11 rotates the hub 2 to move a recess 15 therein out of alignment with a ball 5 carried by a fixed hub 3. On release of the shaft 19 a radial face 14 abuts the ball 5 and holds the shaft 19, hub 2, gear 1 and pinion 11 in the axially displaced positions. The drive from the motor to the web drive mechanism rotates the pinion 11 which drives the shaft 19 in the opposite rotary direction through 100:1 reduction gear 1. When the control shaft 19 is returned to its initial position the cam recess 15 engages the ball 5 and permits leftward axial movement of the control shaft under the action of the spring 6 to disengage the drive between the electric motor and web drive mechanism. A pin 19 axially slidable with the gear 1 operates switches 10 which respectively start the electric motor and release a brake on the web drive mechanism. A tongue 7 fast with the fixed hub 3 engages a stop 8 on the hub 2 to prevent reverse rotation of the control shaft 19 from its zero position.
