Title: Edge-runner mill
Inventor: SVENSSON SVEN OLE
IPC: B02C15/00
Filed: 1981-06-26
Abstract: A vertical roller mill has a grinding table (1) with grinding rollers (3).

Patent GB-2262206-A (GB)
Title: A signal synchronisation circuit
Inventor: SPENCER SIMON HOWARD
IPC: H03L7/081
Filed: 1982-03-02
Abstract: A signal synchronisation circuit enables an incoming signal which contains noise and phase jitter to be used to generate a clean signal which is synchronised with it. The circuit enables the generated signal to be synchronised very quickly, as the acquisition time is related to a very high frequency component which is superimposed upon the received signal. A phase correlator enables the output signal to be synchronised accurately with low frequency signal components of the received signal, but once correct synchronisation has been obtained, the phase correlator is switched out of circuit so that the phase stability and frequency accuracy of the generated signal are determined by the properties of a phase locked oscillator. <IMAGE>

Title: Electrical connectors having improved resistance to electrical breakdown
Inventor: WEST GEOFFREY LAMBERT
IPC: H01R13/53
Filed: 1982-04-03
Abstract: An electrical connector comprises plug and socket parts 1,2 having generally cylindrical insulating body members 3,4 one of which has an axially extending central boss 5 of generally frusto-conical form defined by a re-entrant annular cavity 6 for receiving a tapered wall section 7 of the other member whereby the two members engage one another to provide an extended re-entrant tracking path 8. The plug and socket parts are constructed and arranged so that, as the body member 3,4 are pressed together, any air which becomes trapped within the connector is forced into an electrically unstressed cavity 10 between the forward end of the plug pin 11 and the closed end of the co-operating socket member. <IMAGE>

Title: Manually controlled power assisted press
Inventor: ROGERS PETER ROWLAND
IPC: B30B1/20
Filed: 1982-04-30
Abstract: A manually controlled power assisted press has a cylinder 2 of a double acting piston and cylinder secured to a C-frame 1. The piston 3 is restrained by a peg 26 from rotation relative to the cylinder and has a rod 8 for carrying a press element. A drive shaft 21 screw engages the piston 3 so that rotation of the shaft axially displaces the piston and its cylinder. The shaft 21 is coupled to an input shaft 18 by way of valve 10 having relatively rotatable parts 16 and 17, part 16 being rotatable with shaft 18 and part 17 being rotatable with shaft 21. Valve parts 16 and 17 are rotationally adjustable and rotationally biased relative to each other and to a neutral condition by a resilient torsion rod 27. Input shaft 18 is rotatable by a handwheel 19 and a differential in torque between that applied to the shaft 18 and the resistance to rotation of the shaft 21 adjusts the valve 10 from its neutral condition to direct hydraulic pressure to the piston chambers 6, 7 to assist in displacement of the piston. The resilient resistance provided by the torsion rod 27 to adjustment of the valve 10 provides a feed-back or feel through the handwheel 19 to give the operator an indication of the hydraulic pressure being applied through the piston rod 8. <IMAGE>

Title: Improvements in and relating to control systems
Inventor: BARKER JOHN CARRINGTON
IPC: G05B9/03
Filed: 1983-01-15
Abstract: Two nominally identical control units A and B are provided for producing two identical and synchronous series of control signals, such as for controlling the lighting up procedure of a gas burner. The control signals are produced by PROMs 56A and 56B. Each unit A, B has four comparators 74, 76, 78, 80, each connected to compare one of the control signals from its own PROM with the corresponding control signal from the other PROM. Each comparator shuts down the system, by energising a line 100 (e.g. via line 92A in respect of comparator 74A) if it detects a lack of equality between the two control signals compared. Therefore, each of the two control units A, B contains means for checking the operation of the other whereby the system is shut down if, at any stage, the two control units are not calling for the same control action. <IMAGE>

Title: Control circuits and zero-current- crossing semiconductor-thyristor gate feed shunting in power control of all cos-0 loads
Inventor: HOWARD MICHAEL SHMUEL
IPC: H02M1/08
Filed: 1983-08-05
Abstract: Firing of semiconductor thyristor gates is usually done with currents in great excess of the minimum needed and/or by zero-voltage-crossing means, to prevent or minimize RFI and di/dt damage. For an inductive load, zero- voltage-crossing firing distorts the load current because of commutation before next zero-voltage crossing. This invention proposes to fire thyristor gate at zero-current-crossing point of load, using minimum possible gate current, by supplying correcting leading-current gate-feed means (3, 3a), with current lead of either exactly 90 DEG  el. ahead of load current, when load- current lag is known, or at least 45 DEG  el. ahead of load current, when said gate current is 1.414 times the minimum needed for firing. Said gate-feed means are permanently connected to thyristor (2) gate via tap resistor (5), and protective resistor (4). Further characterizing the invention is the use of shunting means controlling load current by reducing gate current below minimum necessary at control point. Interface means (9, 17, 18) are optionally used between shunting means and gate-tap means. Various low-power circuits are developed, most being powered directly from gate current itself, for variegated control functions, without use of integrated circuits and/or external power supply, for automatic, manual, proportional, reset, and/or nonreset applications.   Positioning gate-feed means before the load gives quasi-d.c-gate firing. <IMAGE>

Title: Process and apparatus for continuously making a strip of baked dough
Inventor: HAAS SNR FRANZ
IPC: A21B2/00
Filed: 1983-08-23
Abstract: A process for making a strip of baked dough, particularly a wafer strip, comprises continuously applying liquid dough to the face side of a revolving endless baking surface (3), which is heated on its rear. The strip of dough (T) is heated on its bottom surface as its bottom surface contacts the face side of the baking surface, and its top surface, which faces away from the baking surface, is directly heated by infrared radiators (9) which are spaced from the baking surface. In another embodiment of the process, the baking surface is situated on a baking disc which rotates about a vertical axis and is heated on its bottom surface. Dough is poured on to the thus heated baking surface and the top surface of the dough is heated by infrared radiators spaced from the said baking surface. <IMAGE>
