IPC: H04R1/08
Filed: 1966-07-05
Abstract: 1,136,794. Microphones. COSMOCORD Ltd. 5 July, 1967 [5 July, 1966], No. 30062/66. Heading H4J. A microphone comprises a casing having a body 10 and a cover 19 mounted by pivots 16, 17 on the body 10. A microphone transducer (14), Fig. 2 (not shown), is mounted in the body 10. The cover 19 is movable between a first position in which it obstructs or modifies sound apertures 13 against the ingress of sound (Fig. 4) and a second position in which it serves merely as a support member for the microphone. Thus in the second position the cover 19 may be completely open and in line with the body 10 to act as a handle (Fig. 1). Alternatively, in the second position the cover 19 may be at an angle to the body 10 and act as a rest for supporting the microphone on a flat surface (Fig. 3, not shown). In the first position the cover 19 is folded to lie closely against the back of the body 10. If a cardioid transducer is used, closure of the back changes the polar diagram to omnidirectional. Closure of the apertures 13 may be improved by using a foamed polyurethane pad 20. The back of the body 10 may carry an acoustic filter to modify the acoustic effect due to the rear slots. A decorative fret (15), Figs. 2, 3 (not shown) of perforated plastics or expanded metal may fit over the front of the body 10.

Title: Apparatus for and method of manufacturing rolled bandage cots and the like
IPC: A61F13/10
Filed: 1953-10-30
Abstract: 743,045. Surgical dressings. SCHOLL MANUFACTURING CO., Ltd. Oct. 30, 1953 [Jan. 14, 1953], No. 30082/53. Class 81(2). A rolled bandage cot made of at least two plies of tubular bandage is formed by threading a length of tubular bandage on to a hollow member, transferring a portion of the bandage on to a mandrel, constricting the medial portion of the bandage, retroverting the portion of bandage on the hollow member on to the portion on the mandrel, rolling the two-ply bandage cot on the mandrel and stripping it from the mandrel. A length of tubular bandage 38 is threaded on to a hollow tubular member 30 which is mounted on abase 12, the threading being assisted by a bullet-shaped assistor (not shown) which is afterwards removed. A mandrel secured to a drive rod 22 and having a sponge rubber cover 26 and a metal tip 28 is slidably mounted on a support 13 which is pivotally mounted on the base 12. The support 13 is pivoted so that by using the drive rod 22 the mandrel is inserted into the hollow member 30 which is provided with a mandrel stop 33. On withdrawing the mandrel a portion of the tubular bandage 38 is transferred to the mandrel. The medial portion of the bandage is then constricted by either tying with thread 70 or tape or twisting the mandrel. The mandrel is reinserted into the hollow member 30 so that the portion of bandage on the hollow member 30 is retroverted over the portion of bandage on the mandrel. The mandrel is then swung round so that it is in alignment with mechanism for rolling and stripping the bandage, Fig. 1. As the mandrel approaches this mechanism a lever 39 is tilted by the drive rod 22 so that electromagnetic means are energised for separating two roller holding bracket.arms 49, 50. Rollers 56, 57, made of sponge rubber are thus separated and the mandrel is inserted between them, the drive rod 22 then disengaging the lever 39 so that the rollers 56, 57 are pressed against the mandrel by a spring 60. The rollers 56, 57 are rotated by a suitable power source (not shown) and the mandrel is withdrawn from between them so that the bandage 38 is rolled up, Fig. 11, and stripped from the mandrel. The bandage cot may be made from more than two plies by using a larger piece of tubular bandage and reciprocating the mandrel to retrovert the plies one over the other to the required number.

Filed: 1969-06-16
Abstract: 1,211,959. Semi-conductor devices. RCA CORPORATION. 16 June, 1969 [28 June, 1968], No. 30282/69. Heading H1K. As shown a bi-polar transistor has its base region 2 and its emitter region 4 interdigitated, the emitter being in the form of a double comb the web part 12 of which is provided with a conductive contact layer 16, on either side of which are conductive contact layers 18 extending along the emitter fingers. The finger contact layers 18 are spaced from the part 6a of the emitter-base junction 6 surrounding the emitter fingers by a distance s and from the web contact layer 16 by a distance d so that the emitter region at these gaps constitutes two resistors in series in the current path between layer 16 and the part 6a of the emitter-base junction. Those parts 6b of the base-emitter junction at the extremities of the base fingers are spaced a distance d<SP>1</SP> from the web contact layer 16 and according to the invention the device geometry is designed so that d<SP>1</SP> # s + d.Pf/Pb, where Pf is the permieter of one emitter finger (length of junction part 6a) and Pb is the width of one base finger extremity (length of junction part 6b). This relationship reduces second breakdown at the base finger extremities. The base region may be an epitaxial layer or may be a diffused region in the collector zone. The base region is contacted by means of a conductive layer 20 having fingers 24 extending along each base region finger. The ends of the emitter and base region fingers may be chamfered or rounded and in this case the value of Pb is taken as the width of the base fingers where they are not rounded or chamfered.

Abstract: 1,202,931. Photographic film processing. GEVAERT-AGFA N.V. June 27, 1968 [July 3, 1967], No.30626/67. Heading G2A. In apparatus for processing an exposed photographic web, the processing material is applied to the web as a thin viscous layer in an atmosphere of which the wet bulb temperature can be maintained at a substantially constant value, and the relative humidity is maintained equal to or lower than the relative humidity with which the processing composition is in equilibrium with the atmosphere in the processing zone. Fig. 1 shows the processing apparatus, in which exposed film is led from a magazine 18 into a feed chamber 11, a developing chamber 12, a fixing chamber 13, a rinsing chamber 14 and a drying chamber 15. In chamber 12, the developing material is applied to the film as it passes over a roller 28, from an extrusion hopper 32, to which it is pumped from a constant temperature supply Fig.3, (not shown). Air is constantly circulated through chamber via inlet opening 33 and outlet opening 34, from conditioning chamber or humidifier 50 Fig.2. Water or an aqueous solution of sodium chloride is pumped into the chamber through downwardly directed spray nozzles 56, and the excess collects in a sink 55 at the bottom of the chamber. From here it is pumped up again, heated by a heater 57 and re-circulated. Moisture losses are made up from a constant level tank 60 fed from a supply 62. A second electric heater 68 is provided within the chamber itself. Heater 57 is controlled by a thermostat 67 dipping into the liquid in sink 55, and heater 68 is controlled by a thermostat 78 near the applicator hopper 32. As air from outlet 34 passes back into the humidifier via conduit 53 and compressor 54, it is augmented by air aspirated through a small pipe 65, so as to establish a slight over-pressure in chamber 12. Some dimensions and practical operational data are given, and the functioning of the apparatus discussed with reference to a psychometric chart Fig. 5, (not shown).
