Abstract: 1,069,418. Door frames; glazed doors. ALUMILINE CORPORATION. Nov. 6, 1964 [March 23, 1964], No. 45249/64. Headings E1J and E1R. A glazed door has hollow stainless steel framing members 60-66 each with longitudinal internal folded lock seam, and joined together at the door corners by generally channel-sectioned corner connectors, each having one flange and the base extended, and each welded to the framing members. The external framework 11 also comprises hollow stainless steel members, of rectangular cross-section, and with internal folded lock seams (Fig. 2, not shown), screwed together at the junctions via channel-sectioned connectors 42. The door framing member connectors 100 (Fig. 4, not shown) have generally curved flanges contacting the framing member faces with lock seams therealong, to accommodate said seams, and holes are formed through the framing members to allow the insertion of the weld material. The glazing panel 134 is retained in position by channel-sectioned metal retaining members 138 and 140, (Fig. 8, not shown), having return flanges 182 and 184 adjacent the framing members, which flanges are retained by H- spaced clips 135, (Fig. 9, not shown) having spaced, laterally offset flanges 148, 150, 164 and 166 which enable the retaining members to be clipped in an inner or an outer position to allow for varying panel thicknesses.

Abstract: 1510419 Valves R FOWLER Ltd 1 Nov 1976 45347/76 Heading F2V In a cistern discharge valve a flexible closure member 17 on the end of a tubular member 18 is lifted off its seat 9 by the actuation of a pushbutton 36, which is connected to the tubular member 18 by levers 21, 32 and link 33 so that the member 18 moves a multiple of the distance moved by the button 36. The tubular member is held in its upper position by the vacuum created therein by the flow around the lower end and by the cap 38 closing the upper end. A float 39 having a lost-motion connection with the tubular member and moving in a float chamber 10 slowly lowers the tubular member, when flow and the holding vacuum ceases, as the water leaks out of the chamber 10 through restriction 13. The levers and link may be moulded of polypropylene and have integral hinges. A button mounted on the side of the tank may be used for actuation.

Title: Improvements in and relating to Photographic Camera Shutter Systems
Inventor: FUWA ZYOICHI
IPC: G03B9/70
Filed: 1967-10-10
Abstract: 1,198,279. Exposure control. RICOH K. K. Oct.10, 1967, No.46268/67. Heading G2A. A photographic exposure is made by opening a first set of shutter blades by means of a control ring 1, and then closing a second set of shutter blades by means of a control ring 14. Between rings 1 and 14 is a further ring 9 which controls the firing of a flash, and the moment at which the flash is fired can be varied. As shown, ring 1 is urged anti-clockwise by a spring 3 to open the shutter, but is restrained against such movement by a spring-loaded latch 4a. Similarly, ring 14 is urged anti-clockwise by a spring 15 to close the shutter, but is restrained by a latch 18a, held in the locking position by an electromagnet 16. Ring 9 carries a pair of normally open contacts a, and adjacent these is a lever 12 normally biased away from the contacts. A portion 12a of lever 12 extends inwardly beyond the inner rim of ring 9. When the camera is used under normal lighting conditions (i.e. without flash) the exposure time is set by a photo-cell circuit Fig. 4 (not shown). When release 7a is pressed, latch 4a is disengaged from ring 1, which then rotates to open the shutter. After a time determined by the light received from the photo-cell, electromagnet 16 is de-energized, thus allowing latch 18a to be pulled out of engagement with ring 14, so that it rotates to close the shutter. If the flash is to be used, the photo-cell is switched out of circuit and replaced by a fixed resistance, and ring 9 adjusted to a suitable position. In this case, as ring 1 rotates to open the shutter, a pin 2 carried by the ring and projecting inside ring 9 engages against the end 12a of lever 12. Lever 12 is thus pushed over until an arm 12c thereof strikes contacts a and closes them, so firing the flash. Ring 9 can be set in a number of discrete positions, as determined by a click stop 11 and notches 10, so that the time elapsing between the moment the shutter starts to open and the moment the flash is fired can be varied according to choice.

Abstract: 996,721. Semi-conductor devices. TEKTRONIX Inc. Nov. 25, 1963 [Dec. 17, 1962], No. 46508/63. Heading H1K. In a fast-switching diode comprising a monocrystalline semi-conductor body containing a PN junction a recombination centre impurity is distributed throughout the body in such a way that on both sides of the junction its concentration is graded from a mininum value at the junction to a maximum at points remote from it. A typical mesa diode is produced on a mass production basis from a large 5 ohm cm. P-type silicon wafer by coating one side with boron oxide and the other with phosphorus pentoxide and subjecting it to prolonged heating in oxygen to produce a PN junction by diffusion. After removing surface residues gold is evaporated on both faces and diffused in to provide the required distribution of recombination centres. Both faces are then electroplated first with nickel and then with gold, one face etched to form a plurality of mesas and the wafer subdivided into mesa elements. Each of these is provided with a resilient platinum contact on the mesa and finally encapsulated in a glass envelope. When germanium is used as semi-conductor a suitable recombination centre impurity is copper.

The control signal acts to control the amplifier 9 to provide constant gain so as to make the output signal power and phase of the output signal vary more linearly with input signal power and phase. The detector 4 and adder 7 may be as disclosed in Fig. 7. The frequency converter 18 for upward or downward frequency conversion and the local oscillator 16 may be omitted (Fig. 5, not shown). The avalanche diode amplifier 9 shown in Fig. 8 includes a waveguide 20, a variable termination resistor 21, an inner conductor 22 of a coaxial cable 22, 28 connected to supply the bias voltage at 8, Fig. 6, to the avalanche diode 27, a band rejection filter 23, a voltage regulation resistor 24 and a screw 25 for impedance matching.
