Title: Improvements in or relating to lighting fittings
IPC: F21S8/00
Filed: 1951-10-18
Abstract: 704,409. Lighting fittings. GENERAL ELECTRIC CO., Ltd., and HUBBOLD, S. Oct. 1, 1952 [Oct. 18, 1951], No. 24357/51. Class 75 (4) In a lighting fitting for use in an operating theatre and having a lamp 13 in a housing 10 at one focus of an ellipsoidal reflector 10A which reflects light through a light transmitting member 25 and concentrates it on the operating region at or near the other focus of the reflector, at least part of the lighttransmitting member 25 is of dished form centred on the operating region to obviate reflection of the operating region being visible at points remote from the operating region. As shown the housing 10 is gimbal mounted between the ends of a semi-circular arm 34 supported from a vertically adjustable pendant rod 35. The reflector 10A is formed by the specular truncated ellipsoidal inner surface of the housing 10 and is extended at its inner periphery by a dispersive reflector 10B. A domed canopy 11 surmounting the housing 10 houses a lampholder 12 on a carriage 14 which is axially adjustable for focusing purposes on guides 15 by means of a manually operable spindle 16 carrying an eccentrically mounted pin 20 slidable in a groove 21 on the carriage 14. The dished light transmitting member 25 is of transparent glass or plastic and may be annular with inner and outer diameters approximately equal respectively to the inner and outer diameters of the reflector 10A. The centre of the member 25 is closed by a bowl 26, which may be opaque or light-diffusing, secured to the inner periphery of member 25 by screws 27 which support also a cylindrical white-surfaced baffle 28 serving to prevent excessive direct lighting of the transparent member 25. An emergency lamp 40 may be mounted in the housing 10.

Patent GB-1071554-A (GB)
Title: Analogue to digital converters
Inventor: WARMAN STEVEN IVAN
IPC: H03M1/00
Filed: 1964-06-15
Abstract: 1,071,554. Analogue-to-digital converters. DATA LABORATORIES Ltd. June 15, 1965 [June 15, 1964], No. 24768/64. Heading G4H. In an analogue-to-digital converter temperature compensating means are provided having means for applying a reference signal (earth) to the converter after each digitizing cycle, a correction signal which is added to the input of the comparator being adjusted if the comparator indicates that it does not exactly balance the reference signal. Switch (1, Fig. 1, not shown), connects the input lead either to earth or to the input signal (V). In quantization the signal (V) is sampled and stored on capacitor (2). The stored signal is amplified at (3) and applied via the comparator junction to amplifier (5) controlling a logical circuit (14). This controls switches (6, 7, 8) to cause weighted currents to be applied through resistors to the junction to balance the input signal. After quantization is complete switch (1) connects to earth. The output of the comparator now indicates whether the output of amplifier (3) is above or below zero and causes switch (12) or switch (13) to be closed to apply a positive or negative pulse to the capacitor (CB). The pulse applied causes the charge on the capacitor to tend to cancel any signal at the input of amplifier (5). Since a compensation operation is made after each quantization cycle, the charge on capacitor follows the zero drift of the input circuitry and cancels it. In the system described in more detail, the switch (1) comprises two diodes one or the other of which is caused to conduct by signals from a pulsing transformer. The input signal is applied to a level shifting circuit so that the signal to be quantized is always positive. The comparator junction is applied to an amplifier which has a two-state output according as to whether the input is positive or negative. The balance signal is derived from binary weighted resistors which are switched into circuit under the control of corresponding triggers. The triggers are set in turn, in descending order, and reset if the input is thereby exceeded. The two-state amplifier output is converted to signals of + 1 volt and - 1 volt one of which is briefly connected to the capacitor by a diode switch at the end of the quantizing cycle. Timing pulses are derived from the taps of a delay line.

The upwardly and downwardly projecting flanges 52, 58 of the measuring chamber parts 48, 54 are an interference fit to ensure liquid tightness of the chamber. Openings through the bottom and top surfaces of the parts 48, 54 communicate with the inlet and outlet ports respectively.

Title: A mechanical press for printing standing text with differing addresses
IPC: B41L47/46
Filed: 1930-08-23
Abstract: 358,658. Printing - machines. SCHWARZWALDER, F., 28, Feurigstrasse, Sch÷neberg, Berlin. Aug. 23, 1930, No. 25262. [Class 100 (ii).] Cylinder machines; addressing-machines.-In a machine for printing constant matter in combination with variable addresses and of the kind comprising a flat bed and a travelling impressioncylinder, the cylinder is given an accelerated rotary movement on its way from the starting position to the forme and is again accelerated after leaving the forme until the end of its stroke, the acceleration being provided by means of racks actuated from the main drive: this reduces the distance the cylinder travels, and therefore allows the length of the bed to be reduced. As shown, an impression-cylinder 2 mounted in a reciprocating carriage 1 actuated by means of an oscillating lever 3 is rolled over a forme supported on a bed 9, address-plates stored in a magazine G being moved in succession into printing position adjacent the forme. The cylinder 2 carries at each end a pinion 6 engaging a rack 8 in gear with a pinion 11, and both pinions 11 are fixed on a shaft 12 rotated by a segmental gear 14 carried by a lever 15 connected to a slidable rod 16 actuated by a pawl 20 carried by the lever 3. At the commencement of the printing stroke, the cylinder is in position I, and the pawl rests in a seating in a block 22 fixed to the rod 16, which therefore moves with the lever 3 so as to slide the racks 8 to the right and increase the speed of rotation of the cylinder. In position II where printing commences, the pawl is raised off the seating by a cam 21, and the racks are stationary until position III is reached, when the pawl meets an abutment 24 on the rod 16 whereby the racks are again actuated until the end of the stroke, i.e. position IV. When the address is to be printed on the left side of the sheet instead of the right side, the forme is shifted to the left, and the members 21, 24 are moved to the right so as to discontinue and recommence the movement of the racks at earlier points in the stroke of the carriage whereby the sheet carried by the cylinder 2 still registers correctly with the forme. In a modification, the racks 8 are actuated by a pivoted lever connected to a reciprocating rod actuated by an exchangeable cam on the main shaft.

Abstract: 278,017. Akt.-Ges. Brown, Boveri, et Cie. Sept. 27, 1926, [Convention date]. Regulating or controlling.-In regulating apparatus for the feeding of steam boilers, the mechanism which closes the feed valve also opens a no-load valve to permit the flow of a quantity of water between the pump and the tank. The boiler 1 contains a regulator 3, -shown of the expansion type heated by steam,- which varies in length according to the water level. The regulator operates a rod 5 connected to the feed valve 6 and the no load valve 7. The latter valve 7 is kept closed by a weight 9 or a spring and the valve is opened before the complete closure of the valve 6. A small quantity of water can then circulate through the pump 8, the pre-heater 10, the valve 7 and the tank to keep the pump cool.
