Title: Directional Control Device for a Source of Light
Inventor: HAGNER BO ANDERS VILHELM
IPC: F21V3/00
Filed: 1968-05-23
Abstract: 1,173,408. Lamp fitting. B. A. V. HAGNER. 23 May, 1968 [31 May, 1967], No. 24639/68. Heading F4R. A method for the directional control of a source of light in the form of one or more fluorescent tubes comprises positioning in the path of the light source a panel structure consisting of a facia panel having projections in the form of segments of a cylinder which extend parallel to the axis of said tube or tubes in combination with a support sheet having a plurality of light deflecting and transparent zones in the form of strips extending in the same direction as that of the projections, and adjusting in a direction parallel to the plane of the facia panel the relative positions of said zones and said projections, whereby light beams passing through the transparent zones will, on striking the projections, be deflected and be projected out of the structure in a concentrated manner and at a predetermined angle. The transparent zones 4 are provided on a transparent plastics member 5 which may lie adjacent the facia panel 1 having cylindrical segments 2 or be separated from it by a small air-gap. The transparent zones 4 are arranged in relation to corresponding segments 2 so that all light passing through one zone reaches only the corresponding projection. The upper surface of the light deflecting zones 3 should preferably be white or light-reflecting whilst the lower surface is black. This may be achieved by painting, metallizing, screen printing or roughening the surface of 5. The zones 3 may however be translucent rather than opaque and transmit light of one colour, e.g. blue. The transparent zone 4 may not be symmetrical with respect to the segment 2 but asymmetric thereby producing an asymmetric light distribution. A complete lamp housing is exemplified (Figs. 5 and 6, not shown) wherein a plurality of fluorescent tubes (7) are enclosed in a housing (6) having a transparent member (5) adjacent panel 1 and thumb screws (9, 11) to adjust the horizontal and vertical setting of the transparent member.

Title: Improvements in or relating to the setting mechanism of variable condensers and the like in radio and electrical apparatus
IPC: G05G7/04
Filed: 1949-09-28
Abstract: 682,681. Electric condensers. STRATTON & CO., Ltd., LAUGHTON, H. A. J., and COX, H. N. Dec. 27, 1950 [Sept. 28, 1949], No. 24859/49. Class 37. [Also in Groups XXIV and XL (c)] A setting mechanism for a variable condenser or other electrical component comprises a driving member and a driven member having spaced, parallel rotational axes, a crank-pin on the driving member being slidably engaged between two rail members on an arm on the driven member which are urged together by a spring, so that backlash is substantially reduced. The arrangement provides a variable ratio drive. In Fig. 3 a control knob 10 is frictioncoupled to a disc 14 which carries a pinion 16 and a split gear 17 of the type used to take up backlash. Pinion 16 drives a split gear 22 which carries a pin 30 and is mounted on shaft 23. Pin 30 engages a radial arm 36 which is fixed to the condenser spindle 37, as shown in Fig. 2, by means of two rail portions 43, 42, which are urged together by springs 45 to permit radial movement of pin 30 along arm 36 without backlash. Rotation of knob 10 thus produces rotation of arm 36 and the condenser plates at a velocity which varies according to the position of arm 36, and the arrangement may be such that the ratio of angular movement of knob 10 to the frequency of the tuned circuit is substantially constant. Gear 22 also rotates pinions 24 and 25 which are fixed to drums of insulating material and which control the movement of a cable 26 to move a pointer along a tuning scale. The split gear 17 drives a pinion 18 which is associated with a further disc bearing a scale to provide a fine tuning indicator. A fly-wheel may be associated with the control knob spindle. The end of pin 30 carries three grooved rollers to reduce friction. The device may be used to control other electrical components such as a potential divider.

Title: Improvements in or relating to an electronic stepping register
IPC: G11C19/20
Filed: 1951-10-25
Abstract: 741,595. Valve circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 25, 1951 [Nov. 28, 1950], No. 24962/51. Class 40 (6). [Also in Group XIX] An electronic stepping register comprises bistable grid-controlled trigger elements connected in cascade by means including a resistor connecting each of two output circuits of one trigger to an electrode of a different diode coupled to a different grid of the next trigger, the stepping being effected by applying a source of varying potential to the other electrode of all the diodes. Fig. 1 illustrates the principle of the invention. The trailing edge of a positivegoing square pulse applied at B to the crystal diode will produce a sharp negative pulse through condenser K at output point D if point A is at a high voltage, and no appreciable output if A is at a low voltage. In the stepping register shown in Fig. 6 including trigger stages each comprising a pair of cross-couple triodes such as T1, T2, the anode circuit points A1, A2 of the first stage are connected through resis. tances R1, R2 to diodes D101, D102 and to condensers K1, K2 and the control grids of the second stage, similar connections being provided between the other stages. Positive advance pulses are applied from line 19 to points such as B1, B2, and the cathodes of all the diodes, and produce a negative pulse at one or other grid of a trigger stage only if the previous stage was in a different condition. In the initial or zero condition, all stages have the right-hand triodes conducting, and entry pulses representing binary " 1," may be applied, between successive advance pulses, over line 24 to the first stage. In modified registers, binary " 0 " and " 1 " are represented by pulses entered on separate lines, the entry and advance pulses may be applied simultaneously, and the stages may be connected in a closed ring which repeatedly supplies control voltages from the anode outputs of the stages to another register, a computing or a recording device.
