Abstract: 977,946. Valve and transistor amplifying circuits; line transmission systems. NIPPON ELECTRIC CO. Ltd. Oct. 25, 1961 [Oct. 25, 1960; April 18, 1961; April 25, 1961], No. 38237/61. Headings H3T, H3W and H4R. An amplifier with means to guard against interruption of operation comprises a plurality of amplifying paths. e.g. u 1  and u 2 , Fig. 3, the paths being connected in parallel by hybrid circuits H3 and H4 and feedback, via the feedback circuit # from the output of the hybrid H4 on the output side of the amplifier to the input of the hybrid H3 on the input of the amplifier, being provided to stabilize the gain of the amplifier in the event of a failure in one of the amplifying paths. To monitor the operation the signal levels in each path are checked one against the other or against the output level. Fig. 5 shows one embodiment in which the amplifiers Á 1  and Á 2  are paralleled by hybrid transformers T 1 <SP>1</SP> and T 2 <SP>1</SP> the feedback voltage being taken in series with the output over T 4  and applied in series with transformer T 3 . In an alternative arrangement, Fig. 6 (not shown), the feedback is derived across a resistor inserted in the common lead joining the output transistor emitters to earth, thus eliminating the phase shifts caused by the transformers T 2 <SP>1</SP> and T 4  from the feedback circuit. Other types of hybrid transformers are described with reference to Figs. 8a, 8b and 8c (not shown).

Apparatus for displaying any one of a number of preselected characters, such as the numerals 0-9, comprises a group of units each enclosed in a housing 10 and including a circular stator 20 of magnetically conductive material but containing no permanent magnets, and a rotor comprising a cylindrical character display surface 25 connected with a permanent magnet 35. Electromagnets 23 mounted on pins 21 are at least equal in number to the number of preselected characters and are disposed around the stator so that no two are in diametric opposition. The electromagnets comprise coils, each of which has one end connected to a common terminal 41 and the other end to independent terminals 40, whereby a source of power such as a battery 43 can be selectively connected to any one of the coils to attract one pole of the magnet 35 thereto and so cause the surface 25 to rotate and display the associated character through a window 13. To avoid excessive oscillation before the magnet 35 comes to rest and to prevent it from movement if the apparatus is knocked, an eccentric magnet having a pivot nearer one pole than the other, as indicated in dotted lines in Fig. 2, may be used.

Title: Tractor protector valve
IPC: B60T13/62
Filed: 1957-12-16
Abstract: 833,560. Tractor-trailer braking systems. WAGNER ELECTRIC CORPORATION. Dec. 16, 1957 [Feb. 28, 1957], No. 39012/57. Class 103 (1).  In a protector valve 2, adapted to receive a service line 10 and an emergency line 3, the valve 2 is compatably operable with both the metering and non-metering type trailer relay emergency valve in that the tractor protector valve will not over-ride or obviate the emergency function of either type relay emergency valve under any emergency condition. This characteristic is obtained by means of an exhaust check valve 76 normally held closed by a spring 77 but adapted to vent the chamber 36 under the circumstances in which the pressure fluid leaking through the exhaust passages 63 and 70, aided by the effect of spring 66 overcomes the downwardly-acting force of pressure from the emergency line 3 acting above the diaphragm in passage 31. The diaphragm 28 is then moved upwards with a snap action, putting line 17 to exhaust and causing operation of the trailer relay emergency valve 18. A protector valve so constructed thus causes emergency application of the non-metering type of trailer relay emergency valve, in which application is caused at a predetermined fluid pressure differential between the trailer reservoir and emergency line, and such application is obviated because of the fluid pressure feed-back from the trailer reservoir into the system, which eventually depletes the pressure fluid in the trailer reservoir.

Abstract: 1462346 Laminated paper and board ROHM GmbH 2 Oct 1975 [2 Oct 1974] 40436/ 75 Heading D2B A process for making laminated paper and board on a papermaking machine comprises (a) applying an aqueous suspension of a thermoplastic synthetic resin having a t# max  value not exceeding 70C and a particle size of 10-300 Ám to the surface of a first sheet of paper produced on a sieve of a papermaking machine; (b) superimposing a second sheet of paper produced on a sieve of a papermaking machine on the first sheet of paper; (c) removing by suction at least some of the water in the first sheet after the aqueous suspension has been applied thereto, this being effected before, during, and/or after superimposition of the second sheet of paper on the first sheet of paper; and (d) subjecting the resulting laminate to a temperature above the t# max  value of the resin to bond the sheets of paper together. The latter step may be effected by drying, calendering, or pressing at an appropriate temperature. The laminate may comprise outer sheets of relatively high quality paper e.g. obtained from bleached cellulose and inner sheet(s) of relatively low quality paper e.g. obtained from mechanical wood pulp, unbleached cellulose, or waste paper.

A thickener e.g. carboxymethyl cellulose, polyvinyl alcohol, alginates; polysodium acrylate or methacrylate, or a cationic water-soluble melamine resin, may be added to the aqueous suspension of resin particles. The suspension applied to the paper may also be added to the paper pulp from which the paper sheets are made.

In apparatus for growing monocrystals from a seed crystal immersed in a solution by slow evaporation of solvent from the solution, the tank 3 containing the solution is surrounded by a constant temperature jacket 2, solvent vapours condense in the upper part of the tank, the condensate collects in an annular channel and continuously flows out through pipe 11 into cylinder 15 the volume of which is gradually increased by slow downward movement of piston 16. The movement of the piston is effected by cam gear 17 driven by electro-magnet 18, the speed of the downstroke being controlled by program setting device 8. When the cam 17 has performed one revolution, the piston reaches its lowest position and opens hole 22, through which the condensate flows into tank 23, while the piston rapidly returns to its highest position under the action of spring 24, whereupon the piston begins to travel downwards again, and the cycle will be repeated.

Abstract: 1458465 Fluid dispensing apparatus DRESSER INDUSTRIES Inc 20 Sept 1974 [20 Sept 1973 17 Jan 1974] 41127/74 Heading A4T A self-service dispensing apparatus for liquid or gaseous fuel comprises a series of dispensers 24 served by at least one storage tank, a display of volume and cash value of fluid dispensed at each dispenser a memory for storing digitally the volume and cash values, and a control console 10. The control console can be addressed to a selected dispenser to cause the stored information to be displayed thereat. The information is stored in a temporary memory and retrieved by using a numerical keyboard which identify the dispensers. The dispensers 24 have a manually operated switch 46 and a circuit responsive to operation of the switch to reset the memory. The service station with the dispensers is coupled by a telephone or radio link 16 with a central office so that up to date information can be obtained. The operator of the service station can call on any dispenser to display a gallon and cash value sale and also call up a display of the preceding sale for that dispenser by a recall key. The power supply 18 of the apparatus has a main supply 20 and a battery 12 for use if the power fails in order to protect the memory. The amount of dispensed fuel is measured by flow meters with apertured discs positioned between LED 68a, 68b and photo-transistors 69a, 69b. The pulses produced are shaped by a circuit, Fig. 9 (not shown), and supplied to a central processing unit 114, Fig. 4, to which the keyboard 26 and the memory 116 are connected. The level of fuel in the or each storage tank 25 is also sensed and fed to the processing unit 114 for retrieval when required. A flip-flop circuit 100, Fig. 3, has an "in use" input and its other input is from a "power on" signal or a "device select" signal accompanied by a "reset" signal. The output of the flip-flop is fed to a  "ready" lamp 34 on the console. The apparatus has two modes of operation i.e. a "pump control" and "data entry" determined by a switch 28 on the console. The pump or pumps in the storage tanker are controlled by switches 87, Fig. 3, operated by a solenoid 85 when the switch 46 is closed.
