Title: Multi-stage differential amplifier circuit with means for compensating the temperature drift of a constant current source transistor
IPC: H03F3/45
Filed: 1975-05-23
Abstract: 1490257 Transistor amplifiers TOKYO SHIBAURA ELECTRIC CO Ltd 23 May 1975 [30 May 1974] 22648/75 Heading H3T In a multi-stage differential amplifier in which the first stage A1 is coupled in unbalanced fashion to transistor Q4 in the second stage A2, the bias voltage on the base of transistor Q5 is arranged to vary with temperature in the same way as the input to Q4 varies with the temperature of the current source Q3, R2 to compensate therefor. Q3 and Q7, being part of an integrated circuit, have the same temperature characteristics, and the collector current of Q3 is twice that of Q7. The voltages dropped across identical resistors R1 and R5 are therefore equal regardless of temperature. Other ratios of collector current may be used with corresponding choice of R1 and R5. The current source Q3, R2 may comprise two parallel branches so that each transistor may be identical to Q7, Fig. 2 (not shown). Further stages of amplification may be added, with the bias transistor being connected to the current source of the preceding stage as described above, Figs. 3 4 and 5 (not shown). When the amplifier is used for video signals, a clip circuit, gamma circuit or filter may be provided at C.

Abstract: 1,086,544. Making bread. P. J. BOORAS. May 20, 1966, No. 22669/66. Headings A2A and A2B. In the continuous manufacture of bread, bread dough including a fast raising leavening agent (e.g. carbon dioxide which may be added as a gas or in solution), is extruded as a bar, the bar is shaped and heated as it is advanced through a continuing arrangement at atmospheric or superatmospheric pressure, and then the shaped and baked bar is cooled in a chamber at atmospheric or reduced pressure and cut into loaves which are sliced and wrapped. The continuing arrangement is made up from four vapour porous endless belts 19, 20, 22, 24 made of woven glass fabric, polytetrafluoroethylene or silicone rubber coated with or containing a heat dissipative conductor, e.g. copper or carbon black. The heating means may comprise dielectric plates connected to a high frequency generator and the dielectric field produced thereby heats the conductors in the belts such that the bread is baked and browned by dielectric heating and by radiant heat from the heated conductors. The pressure applied to the bar to shape it may be varied as the bar is advanced through the continuing arrangement.

Title: Automatic telephoning device
Inventor: SPROULES DONALD ORR
IPC: H04M1/276
Filed: 1962-06-13
Abstract: 1,026,684. Automatic exchange system. BROCKS ALARMS Ltd. June 12, 1963 [June 13, 1962], No. 22674/62. Heading H4K. A device for automatically dialling a telephone number on operation of an alarm circuit comprises a relay operable by the alarm circuit to make connections to the telephone line and to energize means for scanning and reproducing recorded signals, and transistor circuits responsive to the recorded signals for generating the dialling impulses. As shown, momentary short-circuiting of the alarm contacts AB energizes relay RL3 which locks, energizes gramophone motor M and makes connection to the telephone line. The recorded dialling signal comprises a continuous 2À5 kc/s. tone on which is superimposed pulses of 400 c/s. tone corresponding to the dialling impulses. The signals are reproduced by pickup arm PU and applied to transistor amplifiers TR1 and TR2. The 2À5 kc/s. tone is developed across the primary of transformer T1, rectified by D1 and operates transistor switch TR3 to energize relay RL1 and loop the line. The 400 c/s. tone is developed across R8, rectified by D4 and applied to transistor switch TR4 which energizes high-speed relay RL2 which follows the pulses and generates the dialling impulses by opening its contact RL2S. At the end of the number the 2À5 kc/s. tone is terminated and relay RL1 releases. Recorded speech is then applied to the line by transistor amplifier TR5 over transformer T2, diode D5 providing overload protection. When the message ends the normal pick-up switch opens, releasing RL3. The apparatus is manually reset by placing the pick-up in the first groove of the record. A narrow band-stop filter centred on 2À5 kc/s. is used during recording of the speech message to prevent unwanted operation of RL1. The gramophone record may be replaced by a magnetic tape or drum.

Abstract: 1,151,724. Controlling reactors. BROWN BOVERI/KRUPP REAKTORBAU G.m.b.H. 23 May, 1966 [10 June, 1965], No. 22946/66. Heading G6C. In a nuclear reactor, fuel elements are passed continuously through the core and charges in the reactor parameters provide a measure of the nuclear characteristics of the elements. The speed at which the test elements traverse the core region is arranged to be of the same order as the time constant of the core and measuring arrangements. Thus, the core parameter variations will correspond unequally with the fuel characteristics. Each test body is passed consecutively through different parts of the core and the resultant parameter charges measure different characteristics of the bodies. Gases may also be tested when in containers. The reactor operates at a power level between 0 and 1000 watts and uses a fuel 99% enriched and a graphite reflector.

Abstract: 965,824. Shearing. STEEL CONSTRUCTION & ENGINEERING CO. (NOTTS) Ltd. June 13, 1963, No. 23512/63. Heading B3W. Work clamping means for a guillotine comprise at least two fluid-operated work clamping rams, and a common supply line for all the rams, which is also connected to a pressure-responsive actuator for the guillotine drive. The guillotine frame is a welded plate structure which is fully described in Specification 965,823 and has a removable front plate 4 to which is secured a bar 20 having eleven bores 21 forming cylinders for rams 22, each of which carries a pad 23 and is upwardly spring-loaded. Hydraulic fluid enters the bores through passages 25 from a manifold 26 which is formed by a channel section welded to the bar 20 and which supports a finger guard 27 having a transparent panel 28. Slots 29 in the bar 20 and the front plate 4 permit sighting of the edge 30 which is illuminated by bulbs 31. Hydraulic circuit.-Fluid from a pump 57 driven by a motor 58 is fed, at a pressure controlled by a relief valve 64, to one section 66A of a control valve operated by a solenoid 67 and a spring 68. When the solenoid is energized, by operation of a foot-switch, the valve is in the position shown in Fig. 4 so that fluid passes to a supply line 72 which feeds the clamp cylinders and a pilot-valve 73. When the clamps engage the work the pressure builds up and through a line 75 lifts the valve 73 against a spring 74 and admits fluid to an hydraulic cylinder 55 which controls a clutch 49, 50 between the motor 52 and the mainshaft 39. The lights 31 are preferably arranged to switch off automatically when the predetermined clamping pressure has been reached. When the solenoid is de-energized both valveparts 66A and 66B move to the left so that the line 72 is connected to a return line 79 ineluding a non-return valve 80, the clamp rams 22 are released and the line 77 is connected to a return line 81 to release the clutch-operating ram 55, since the valve 73 has been closed by the spring 74. Specifications 896,761 and 965,822 also are referred to.
