Title: Improvements in or relating to rolling mills
IPC: B21B13/14
Filed: 1969-10-20
Abstract: 1286667 Rolling mills BLAW-KNOX CO 20 Oct 1969 [24 Oct 1968] 51440/69 Heading B3M At least one backing roll of a 4-high mill has a bending force applied to its extended ends in order to compensate for normal bending under load, the bending force being derived from the rolling load acting on the mill. In one form, Fig. 1, the necks of both backing rolls 22 and 24 have extended necks carrying respective bearings 66 and 66<SP>1</SP>. Each neck is engaged by a hook 56 pivoted to a rocker arm 50. The arm is carried within a tubular beam 40 and supports a movable rocker assembly 80 between itself and the beam. Rolling loads pass from the chocks 30 to aligned plates 44 and 72, and to a mill screw 74 via the rocker assembly 80 and the arm 50. Since the assembly 80 is offset from the plates and screw, a load is applied to the arm 50 tending to raise the hook 56 and bend the roll 22. The compensatory bending force automatically varies with the rolling load and can be used with a gauge control system to provide both gauge and crown control. The inner end of each arm 50 is held within the beam 40 by hydraulic pistons 52, 54. The pistons can be pressurized when an overload is sensed, the arms 50 thereby being pivoted in a sense to reduce the load. Alternatively the hooks 56 can be openable in response to an overload. Each assembly 80 can be moved horizontally by an hydraulic actuator 96 to vary the amount of bending force generated by a given rolling load. A similar arrangement is shown in Fig. 4; here the bending force applied to the roll ends is positive or negative according to the positions of the assemblies 80. Reference has been directed by the Comptroller to Specification 1,177,786.

Abstract: 1530480 Integrated injection logic device TOKYO SHIBAURA ELECTRIC CO Ltd 29 Dec 1975 53011/75 Heading H1K [Also in Division H3] An integrated injection logic device as shown for example, in Fig. 1, comprises a substrate 11 of one conductivity type carrying a layer 12 of the opposite type through which extends an isolating ring 13 of the one type, in which is formed an opposite conductivity type zone 15 which with the ring and the isolated region 12A defines a lateral injector transistor. The substrate and layer define with further zone 17 of the one conductivity type an inverse vertical transistor across the collector junction of which a Schottky clamping diode is connected. As shown the vertical transistor may have two collectors clamped by respective diodes formed between metallizations 21, 22 and the isolated region 12A, and several input Schottky diodes formed between metallizations 23-25 and the region 12A to provide a multi-input and output NAND circuit. Since the output voltage is the difference between the forward voltages of the clamping and input diodes different metals, e.g. Ti and Pt respectively may be used to form them. Alternatively all the metallization may be of Al and the voltage difference achieved by making the diodes of different area. In a variant the Schottky diodes are formed between a metallization, which ohmically contacts region 12A through a P+ diffusion, and N-regions formed in that region and overlapping the respective collector regions. In a further variant (Fig. 4, not shown) constituting a 3-output inverter the vertical transistor has a single collector zone provided with three Schottky-diode forming output electrodes and a Schottky diode forming metallization ohmically connected to the base via a P + diffusion and constituting the input connection. Conventional steps for forming the devices are specified.

Abstract: 1482019 Photo-electrophoresis EASTMAN KODAK CO 12 Dec 1974 [14 Dec 1973 30 Sept 1974] 53766/74 Heading G2H In a process referred to as Photo-Immobilized- Electro-phoretic-Recording (PIER), in contrast to the normal photo-electrophoretic migration imaging recording processes, it is the unexposed and not the exposed photo-sensitive particles which undergo a net change in charge polarity by interaction with the injecting electrode. To this end the injecting electrode is coated with a layer of "dark charge exchange material" which material is chosen to have a work function less than that of the photoconductive particles to be used therewith, e.g. a metal having a work function of less than 4 electron volts or a suitable concentration, depending on the magnitude of its acceptor properties, of an electron acceptor compound, such as certain substituted fluorenones, in a polymeric binder. Many suitable such materials are listed. The photoconductive toner particles are preferably suspended in electrically insulating liquids at somewhat lower concentrations than used in conventional photoelectrophoresis imaging suspensions, and may contain polymeric charge control agents. The use of molten liquid insulating thermoplastic materials as liquid carriers for the toner particles, or simply the use of the dry toner particles alone, is also envisaged. For multi-colour printing, mixtures of different coloured particles each sensitive to light of their complementary colour may be used.

Title: A control system in combination with a torque producing tool
IPC: F16H39/01
Filed: 1969-11-03
Abstract: 1278620 Nut runners GARDNER-DENVER CO 3 Nov 1969 [14 July 1969] 53849/69 Heading B3N In a control system for a torque producing tool such as a nut runner in which a fluid pressure supply is connected to a fluid actuated motor of the nut runner, fluid operated indicating and recording means is provided which is actuable in response to a predetermined torque and which provides a visual indication and record of the operating fluid pressure conditions during a nut tightening operation and an indication when the operation is completed. To operate the system start valve 70 is actuated which permits a supply of air pressure to valve 68 which is displaced to position b. The actuated valve 68 permits the supply of air to valve 32 which effects actuation of the motors 16 to facilitate a nut tightening operation. As motors 16 operate, air pressure in the feed conduits 38 and 40 is sensed and upon reaching a pressure greater than that supplied from regulator 46, valves 42 and 44 are moved to position b whereupon a pressure signal is sent to the visual indicators 82, 84 and to recording actuators 88, 90 which perforate a card 94. In this condition valve 54 is displaced to position a and provides a pressure signal from conduits 30 and 98 to operate master indicator 86 and recording actuator 92. A pressure signal via conduit 100 retains valve 66 in position a and moves valve 68 to position a whereby valve 32 is moved to position a to shut off air pressure to the motors 16. Orifice 99 prevents rapid loss of pressure through valve 80 in position a and a time delay 102 retards the signal to shift valve 68 to position a to ensure equal torque is supplied to all motors and fasteners. In the event of a motor being stopped due to a faulty tool or component being tightened a second servo circuit becomes operative and which includes conduits 101 or 103, 105, shuttle valve 104 and valve 60 and wherein air pressure from the stalled motor actuates servo valve 66 to position b thereby venting actuator 36 of valve 32 causing the valve 32 to shut off air to the motors 16. A pressure signal from the faulty tool subsequently operating its respective indicator and recording means indicating the malfunction. Pressure air cannot be, supplied to restart the motors until the operator actuates a reset valve 80 to position b. Similarly, a condition whereby  any one of the motors does not reach its respective air pressure, e.g. due to a stripped thread or if a fastening component were missing the reset valve 80 would need to be actuated by the operator. The system also includes means for automatically changing the biasing pressure which holds the control valves 42 and 44 in a position a in opposition to the pressure at the motor inlet ports and whereby a control of the pressure circuit may be effected to prevent premature shut-off of the motors due to an equal torque and hence ensuring that a uniform torque is applied to each fastening component.

Abstract: 1495929 Multiplex communication BRITISH AIRCRAFT CORP Ltd 27 Jan 1975 [24 Nov 1973] 54678/73 Heading H4M In a communication system in which a main digital signal is combined with an auxiliary signal of lower frequency to produce a composite signal for transmission, the waveform envelope of the composite signal being generally determined by the auxiliary signal, the receiver which retrieves the auxiliary signal from the composite signal comprises upper and lower envelope detectors 13, 14 which respond to the upper and lower signal values of the envelope with a discharge time constant substantially greater than that of the digit period of the main digital signal and a selector 17 for selecting the output of one or other detector and feeding the selected output to a common channel 19. The selector is controlled by a circuit 20, 21 such that, wherever the main digital signal is such that its effect on the composite signal would distort the amplitude of the representation of the auxiliary waveform derived from one detector by more than a predetermined amount, the output of the other detector is selected. The auxiliary channel may for example be for carrying routine service or automatic function checking signals. If one envelope detector, e.g. 13 of conventional diode-capacitor-resistor type is used to detect the envelope, a series of 0's or l's (depending on the polarity of the diode in the detector) in the main digital information would distort the detected information, but a detector of the other polarity, e.g. 14 would function effectively. Received bits of the main information are therefore passed to a counter-register 20 which responds on receipt of four successive bits of the same polarity to operate a logic circuit 21. This controls the electronic selector switch 17 such that switch over to the detector 13 or 14 poled in the direction appropriate to the circumstances occurs.

Filed: 1973-11-27
Abstract: 1423890 Electro-medical apparatus SYSTRON-DONNER CORP 27 Nov 1973 [8 Dec 1972] 55014/73 Heading G1N A computer adjunct for use with an impedance type plethysmograph converts the plethysmograph output signals to average D.C. levels and then combines them to provide a signal related to blood flow-rate through the biological segment being tested. Electrode pairs I 1  E 1  and I 2  E 2  are applied to the biological segment 10 e.g. finger or thoracia and signals related to the impedance of the segment are fed to plethysmograph 12. As shown in Fig. 2 curve 47 represents the resistance deviation of the biological segment during one heart pumping cycle and from which blood flow data can be obtained. Output signals are obtained from the plethysmograph proportional to the conductance 1/R o  of the segment, R o  being the quiescent or base resistance of the tissue and bone, the deviation from base resistance #R/R o  and the time derivative d t  (#R/R o ). Computation of the output signals is carried out on the basis that the average value of waveform 47 is proportional to the blood flow for each heart pumping cycle. Multiplier 19 multiplies a D.C. signal obtained from averaging at 17 the resistance deviation #R/R o  with a D.C. signal proportional to heart rate obtained  from feeding the time derivative output signal of the resistance deviation to a one shot multivibrator 22 and averaging at 23 the constant width pulses produced thereby. The product output from multiplier 19 is then multiplied by a fixed factor PL<SP>2</SP>, where P is resistivity and L is the length of the segment between the electrode pairs, and applied to a further multiplier 35 where it is  multiplied by the conductance signal I/R o  adjusted for bias and scale factor at 36. The output from multiplier is thus the blood flow volume through the segment per unit of time and can be indicated on meter 46 as an absolute flow-rate by passing the output through scale factor amplifier to meter 46 or as normalized flow-rate by passing the output through a suitable fixed value multiplier 41.

Abstract: 1,174,236. Negative resistance devices. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 9 Dec., 1966 [10 Dec., 1965], No. 55308/66. Heading H1K. A negative resistance device comprises a symmetrical semi-conductor body with a deep level impurity doped intrinsic region between two extrinsic layers of like conductivity type; a voltage being applied between the extrinsic layers. Fig. 3 shows one embodiment in which Zone 31 is Si doped with a deep-level impurity e.g. Ni, Co, Au, Fe, Cu, Mn, or Zn, by coating the Si body with the impurity by plating or vacuum evaporation and subsequently diffusing the impurity in at 1000‹ C. in H 2  atmosphere. Alloy junctions are then formed using AuSb alloy (giving a nin structure) or Al (giving a pip structure) thereby producing regions 32 and 33. Alternatively the silicon may be replaced by Ge, GaAs, ZnS, CdS, InSb, CdTe, ZnO or PbO. A third connection to the intrinsic zone may be provided for example by region 41 which has the same conductivity type as regions 32 and 33 and is formed by alloying. This region can act as a gate electrode and inject electrons into the body and thus produce avalanche breakdown at a lower voltage than in the device (Fig. 3, not shown) without the gate electrode. The negative resistance may be controlled by pressure.
