Title: Improved earphone
IPC: H04R1/22
Filed: 1958-07-29
Abstract: 900,681. Earpieces. NATIONAL RESEARCH COUNCIL. July 29, 1958 [Aug. 5, 1957], No. 24383/58. Class 40 (4). An ear-muff contains an earphone and has a volume comprising a first part giving unhindered access to the ear and a second part partitioned from the first part in such a way that the second part responds better to lowfrequencies than to high frequencies. As shown in Fig. 5, the ear-muff is a dome 1 of rigid material containing an earphone 6 and having a ring 3 comprised by a fluid-filled sac to surround a user's ear. The earphone itself is sufficient to partition the first from the second part of the ear-muff volume, the region behind and round the sides of the earphone having a poor response at high frequencies. The response may be smoothed out by a soundabsorbent material 11 in the second part of the volume. A diaphragm 8 may also be used to separate the two parts, the diaphragm having a central aperture through which the earphone couples with the ear cavity. Coupling through the diaphragm, which may be rigid, may be by means of sixty small holes, or just two small holes, or by means of four large apertures covering most of the area of the diaphragm and sealed with flexible material as shown in section in Fig. 14 where the earphone is spaced from the diaphragm by a short central column. Coupling through the diaphragm may be by way of slots in the wall of the central spacing column. Alternatively the diaphragm may be made of fabric or plastics sheet. Fig. 7 shows a head-set on which the ear-muffs are pivoted on extensible rod joints 23 and a leather head-band 26 has a sponge pad 25. Specification 791,660 is referred to.

Title: Improvements relating to the manufacture of high-voltage insulating bushings
Inventor: ROTHWELL KENNETH
IPC: H01B17/28
Filed: 1961-07-07
Abstract: 1,038,081. Angled bushings. A. REYROLLE & CO. Ltd. Oct. 5, 1962 [July 7. 1961], No. 24715/61. Addition to 967,853. Heading H2C. The parent Specification describes a method of making a high voltage insulating bushing in which layers of sheet material such as corrugated paper are wound on a mandrel and electrically-conducting inserts for stress grading purposes are interposed between selected layers, the whole being impregnated with a thermoplastic or thermosetting synthetic resin. The present Specification describes a modification for producing angled bushings of this type where the resin is either flexible or becomes so when heated, so that when the mandrel is withdrawn from the moulded bushing a curved conductor to which the insulation shapes itself may be inserted. The internal surface of the bore is first coated with an electrically conductive material to prevent electrical discharge occurring in any pocket of air that may be trapped between the inner surface of the bore and the conductor. When thermoplastic resins such as nylon and polypropylene are used the sheet material has to be more rigid, for example nylon sheet instead of corrugated paper, since an injection moulding process has to be used. The thermosetting resin mixtures used consist of an epoxy resin mixed with an inorganic filler, such as silica flow, and a plasticizer such as polyamide or epoxidized oil. Instead of the inserts, electrically-conducting coatings may be applied to selected layers of the sheet material to constitute the voltage-grading inserts.

Title: Method of making flattened thermoplastic tubing of predetermined desired characteristics
IPC: B29C48/10
Filed: 1948-09-22
Abstract: <PICT:0654550/IV (a)/1> Flattened tubing is produced by continuously extruding molten thermoplastic material through a die 28 to form seamless tubing, passing the tubing with clearance through a perforated cooling ring 36 which blows cold gas on to it, and maintaining a substantially constant volume isolated bubble of gas in the tubing between the die and the nip of a pair of flattening rolls 42, 44. The application of the cooling gas through the ring 36 begins at not more than 3 inches from the point of extrusion and sets the tubing to a predetermined diameter.  The tubing reaches its final diameter at about 1 inch above the final cooling orifice.  The cooling gas may be air at room temperature or chilled air.  The bubble is maintained by blowing gas through pipe 34 and central die orifice 32 into the tubing.  The quantity of gas blown in may be such as to inflate the tubing, as shown; alternatively, the tubing may be allowed to contract to a predetermined diameter less than that of the die by increasing the speed of rolls 42, 44 and utilizing only sufficient internal gas pressure to hold the tubing at the desired diameter.  An electric vibrator 16 accelerates feed of material from hopper 12 into the extruder.  In a modified procedure, Fig. 2 (not shown), the tubing expands after it has left the cooling ring and reaches its final diameter in the vicinity of the rolls 42, 44. Three examples are given.  The material may be cellulose derivative, polymethylmethacrylate, polyvinyl chloride, vinyl copolymers, polystyrene, nylon, polythene, &c.

Abstract: 1348924 Measuring area photo-electrically SIEMENS AG and CARL ZEISS-STIFTUNG trading as CARL ZEISS 19 April 1971 [11 March 1970] 24920/71 Heading G1A In a scanning method of measuring the area of an object a constant signal - Fig.2cis produced each time the object is in a scan path, this signal is then integrated - Fig.2d - and the integrated signal is formed into a pulse - Fig. 2e - whose amplitude is a measure of the length of the scan path containing the object. By combining all the pulses formed from the scanning of a single object in a delay line store having a circulation time equal to the line-wise scanning time a final pulse - 2g - is produced having a characteristic indicative of the scanned area. The scanning is effected either by the flying- spot method, using a secondary electron receiver as a detector to generate the video signal, or by viewing the object with a television camera. There are a number of ways of displaying the result: (a) Each final pulse is superimposed on the video signal and applied to a display unit 7, Fig.1 (not shown). (b) If a number of objects are present in the viewing area, Fig.3a (not shown), the integrated areas of each may be stored as respective pulses Fig.3c (not shown). These may then be presented on the display unit as dots of equal area whose intensity is proportional to the corresponding object area Fig.3b (not shown), and whose position corresponds to the lowest point of the object in the viewing area. Using the last-mentioned display, frequency distributions of objects of different areas may be derived, e.g. for biological examination or for evaluating metal microsections.
