Title: Improvements in or relating to photographic printing apparatus
Inventor: KONIG GOTTFRIED
IPC: G01J1/42
Filed: 1965-07-14
Abstract: 1,082,863. Photo-electric exposure control. PENTAGON DRESDEN KAMERA UND KINOWERKE, VEB. July 14, 1965, No.29878/65. Heading G1A. In an exposure time control device for photographic printing apparatus, a gas discharge tube 1 is switched on to end the exposure when a capacitor 7, the charging of which is controlled by an exposure correction potentiometer 9 and an illuminated photo-detector 11, discharges, the point at which discharging and ignition of the tube occurs being fixed. Initially the switch 8 is in the position shown, the potentiometer 9 being set according to the printing medium being used. After charging through the potentiometer 9, the capacitor is connected, by changing switch 8, to the photo-detector 11, which may be a photomultiplier, and which is illuminated by the printing light, and charging continues until the ignition voltage is reached, producing switching on of the tube 1 and activation of the relay 3 to terminate the exposure. The voltage at which capacitor 7 discharges is determined by the setting of the potentiometer 4 in the cathode circuit of the tube 1, this point being well above the average minimum voltage for ignition for such tubes, so that any new tube connected in the circuit will ignite only at the predetermined fixed voltage. The tube I may be a thyratron or a gas filled triode. The device may be used in black and white or colour printing, and in the latter the potentiometer may be common to all three colour circuits.

Title: Improvements in razors
IPC: B26B21/08
Filed: 1930-10-09
Abstract: 365,149. Razors. MARPLES, S. A., Norton, Walpole Avenue, Chipstead, Surrey. Oct. 9, 1930, No. 30256. [Class 30.] In a razor of the type in which the inclination of the blade or blades to the surface shaved is not varied for strokes in different directions, the means for clamping the blade and also the plain or serrated guards are in the same transverse line or plane as the cutting edges of the blade. Transverse grooves, holes, or conduits are also provided in the blade support so that shaving emollient removed from the face on the forward stroke passes through the razor and returns to the face to lubricate the other blade edge on the return stroke. A single blade d, Figs. 1 and 3, has its cutting edges curved upwardly either permanently or by a clamping spring or bar c passing through slots in end-pieces b on a blade support a and pressing down the central part of the blade between discontinuous parallel ribs e. The ribs are arranged in continuation of the guard teeth f to allow free passage of lather, and longitudinal channels are formed between the ribs and guard teeth under the blade edges. Corner lugs j locate the blade laterally. The clamping bar b, blade edges, and guard teeth f are coplanar and the edges of the blade may rise slightly above the common plane or the guard teeth be made slightly below to improve the cutting qualities. The clamping bar is initially curved upwards at one end to give firmer clamping or it may be omitted altogether, the blade being clamped flat only at its ends by spring clips, its centre part remaining uncovered. The clamping means shown in Fig. 7 comprises a flat bar v having a slot x slidable beneath a headed pivot pin y about which the bar can be rotated in the plane of the blade after it has been slidden far enough forward to free its turned over end z from the holder. A finger projection w facilitates manipulation. There are pins A passing through locating apertures in the blade into slots B in the clamping bar. The double blade form of Fig. 5 uses two flat blades d inclined towards each other with their operable cutting edges overlying a channel n housing a fixed or rotatable guard roller p which transports lather from one edge to the other as the razor is moved in reciprocal directions over the face. The roller may be replaced by upwardly extending guard teeth at the outer edges coplanar with the cutting edges and clamping bars c, the blade support being transversely grooved for the passage of lather. One blade edge acts also as a guard to the other. The blade support a may have a T-handle h, Figs. 1 and 3, or an aligned handle u, Fig. 7, and the handle h may be hollow and provided with a sliding lid to form a space for storage of spare blades or soap. The handle u has a slidable drawer D for the same purpose. The Provisional Specification states also that in the double blade form of Fig. 5, the clamping bars may be joined by pivoted cross-links to provide a parallel motion enabling both blades to be clamped by one movement.

Abstract: 1393748 Overvoltage protective circuits INDUSTRIAL INSTRUMENTS Ltd 25 May 1973 [28 June 1972] 30321/72 Heading H2H [Also in Division H3] In a D.C. voltage limiting arrangement, when the Zener voltage of Zener diode D1 is exceeded, transistor VT2 is biased conductive, thereby rendering power transistor VT1 conductive to limit the D.C. voltage; the current through transistor VT1 is limited by means of resistor R1. A number of such stages are connected in series to limit a correspondingly greater voltage than would be limited by a single stage. In the embodiment, the output from an inverter is applied via fuse FS1 and thermal cut-out SW1 to an arrangement comprising a pair of back-toback Zener diodes KS1 which limits voltage spikes. The voltage across device KS1 is rectified by bridge rectifier circuit D13-16 and smoothed by capacitor C1, which also serves to absorb voltage spikes. The smoothed D.C. voltage is applied to the limiter circuit whereby voltage surges are prevented: if the voltage remains excessive for any length of time fuse FS1 or thermal cut-out SW1 comes into operation.
