Title: Improvements in or relating to light reflectors
IPC: F21V7/04
Filed: 1925-12-22
Abstract: 245,139. Lancelot, R. Dec. 27, 1924, [Convention date]. Overhead lamps; mounting electric lamps in lanterns.-The reflector of an overhead electric lamp comprises two superposed portions ab, bc of shapes obtained as described below, the effect obtained being that the direct light flux plus the reflected flux is so distributed that the surface to be lit has a central area of uniform illumination surrounded by an annular area in which the illumination decreases substantially uniformly in intensity towards the circumference . Lighting units thus constructed, if suitably spaced, thus provide substantially uniform illumination over any desired area. The upper portion bc has a collar h by which it is secured to a telescopic chimney de carried by a ventilating cap f. The inner tube d is provided with two bosses into which are inserted set screws projecting through two slots e<1> in the outer tube e. The two slots e<1> each have a series of diametrically opposite notches such as e", e<111> one of which is engaged by one of the set screws according to the intensity of the sources of light used in the reflector. The special curves of the two reflecting surfaces are built up of parabolic curves having a common focus but with different axes and obtained by a method described with reference to a usual type of lamp in relation to the polar curve of light intensity corresponding to the particular distribution of light required. The particular example dealt with is based on the use of enamel sheet metal having an absorption co-efficient of 30 per cent, but other material such as nickel sheet metal, glass, silica, &c. may be used. According to the Specification as open to inspection under Sect. 91 (3) (a) a single reflector having no upper portion bc may be employed for uniformly illuminating a relatively small area. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to x-ray examination tables
IPC: A61B6/04
Filed: 1953-11-26
Abstract: 733,603. X-ray apparatus. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Nov. 26, 1953 [Dec. 2, 1952], No. 32815/52. Class 98 (1). An X-ray examination table comprises a table-chassis 3 with pivots 4, 5 spaced apart on opposite sides of its mid-point, each pivot having releasable engaging means 8, 9 interconnected by mechanism for placing the pivots alternately into operative condition to permit first one end and then the other of the table-chassis to be tilted upward, means for tilting the tablechassis comprising a rotatable member 14 with an annular rim 23 gapped at 24, and means for blocking actuation of said mechanism except when the table-chassis is in its untilted position. This blocking means comprises a blocking element which moves freely in the gap when the table-chassis is untilted, but moves out of the gap into engagement with the rim when the table is tilted. In the table shown in Fig. 1, the table-chassis is supported on a base 1 enclosing a motor (not shown) driving the rotatable member 14, which consists of a pinion fast with a crank-arm 6 connected by a link 7 to the mid-point of the chassis 3. An X-ray tube (not shown) is movably mounted within chassis 3. The releasable means 8, 9 consist of latchhooks pivoted to the chassis and connected by a link 13, which carries the blocking member comprising a roller 25. If the motor turns pinion 14 anti-clockwise, a roller 18 on crank-arm 6 rocks a cam 17 about its pivot 19. The cam is linked to a lever 15 which is thus rocked clockwise moving link 13 to the right by means of a pin-and-slot connection, so that latch-hook 8 moves into engagement with pivot 4, and latchhook 9 moves clear of pivot 4. Roller 25 is now inside rim 23, and prevents link 13 from moving until the chassis has returned to its untilted position. If pinion 14 is turned clockwise, pivot 4 is freed and pivot 5 is engaged by latch-hook 9, and the table tilts about pivot 5. In this case roller 25 is outside rim 23. In a modification, the members 15, 16, 17 are omitted and a pin replacing roller 25 is engaged by cam surfaces on opposite sides of the gap in rim 23 to move link 13.

Abstract: 1,086,127. Change-giving vending-machines. TATEISI ELECTRONICS CO. Aug. 3, 1965 [Aug. 10, 1964 (3); Nov. 18, 1964], No. 33145/65. Heading G4V. A vending machine actuated by coins of different denominations to dispense articles of different prices has an electric control-system with no moving mechanical contacts and comprising a coin-counter with proximity detectors each detecting a given coin denomination and producing one pulse for each associated coin, pulse counter for each detector and a MEMORY element (flip-flop) supplied with said pulses; a predetermined number of pulses produces an output signal to one of a plurality of lines connected to manual switches for dispensing a selected article by means operable in response to a signal on one said line and on closure of the corresponding switch, change being given if necessary. A dollar or combination of 10 and 50 cents is inserted for an article costing 40, 50 or 60 cents. A 10-cent pulse-counter 18 sends one pulse to a 50-cent pulse-counter 32 after counting five 10-cent coins. On total insertion of 100 cents the counter 32 applies an input to an OR gate 34 whose other input is from the dollar proximity detector 14 and whose output leads to the reset of MEMORY element 40 whereby total insertion of one dollar produces a signal on output line 100 from the MEMORY reset. Similarly a signal appears via NOT elements 63, 65, 67 on lines 94, 96, 98 from appropriate counter outputs on total insertions of, respectively, 40, 50 and 60 cents. The outputs from the counters and from the MEMORY element 40 actuate digital indicator tubes 86, 68, 88 to display the total money introduced. On insertion of appropriate coins a customer presses a selected switch 110, 111 or 112 thereby setting an associated MEMORY 114, 115 or 116 to activate a solenoid 132, 134 or 136 causing an article to be dispensed. Appropriate change is given in 10-cent coins via INHIBIT elements 152-157 by solenoids 172-177. Simultaneously with energization of solenoid 132, 134 or 136 occurs energization of a solenoid 241, 242 or 243 to actuate printing keys (not shown) for recording the price of the article sold as determined by a pulse counter 224. Closure of a switch nullifies the effect of closing any of the others. Pressing of a " cancel " push-button after insertion of money but before pressing any other button causes refund.
