Patent GB-556066-A (GB)
Title: Telephone and like signalling systems
IPC: H04Q1/46
Filed: 1942-08-28
Abstract: 556,066. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (Western Electric Co., Inc.). Aug. 28, 1942, No. 12137. [Class 40 (iv)] A subscriber's number sender which employs reeds for generating currents of several frequencies is arranged so that the level of the currents varies inversely with the frequency, and an equalizer is provided at the exchange for bringing all the frequencies to the same level before they pass to the detecting channels. This arrangement possesses the advantages that all the keys require the same pressure for actuation and that there is less risk of interference by noise currents, which are more pronounced at the lower frequencies. The reeds 4 ... 8 are normally flexed by fingers 23 carried by bars 10 ... 14 which are pressed upwardly by springs 16 ... 20 and are plucked by means of a common pivoted plate 21 which has a series of stepped edges for engaging the reeds. When a pair of bars are depressed by the actuation of a key, the fingers 23 release the corresponding reeds allowing them to rest on the plate 21 and the latter is then withdrawn by means of projections 57 on the bars to set the selected reeds in vibration. At the exchange, the generated currents pass in succession through an equalizer which corrects for frequency variation of the line attenuation, an equalizer which brings all the frequencies to the same level, a broad-band filter, a volume-limiter and thence to the several frequency-selective channels.

Title: Digit embracing surgical pads
IPC: A61F5/01
Filed: 1962-03-29
Abstract: 998,840. Surgical pads. SCHOLL MFG. CO. Ltd. March 29, 1962 [March 31, 1961], No. 12161/62. Heading A5R. A toe pad is made from two superposed body parts, forming the actual pad, and a strap element, comprising a pair of crossed or spaced straps, connected to the body at spaced points. It may be made from a blank comprising two body portions 3, 4, Fig. 4, joined by an X- shaped strap member 7, 8, 9, 10. The body parts are then superimposed, one on the other, and stuck together, as shown in Fig. 2, so that the strap parts can pass around the toe with the web of the X located in the bend of the toe. At the same time the widely spaced side portions are located remote from the actual joint and thus exert no pressure on it if it is swollen. The body portions 3, 4 may have holes 5, 6 which are aligned in the complete pad, so as to accommodate a corn. Other forms of blank are described, one of which, see Fig. 7 (not shown), uses two spaced, parallel strap elements while another, see Fig. 10, has an additional intermediate pad intended to lie underneath a hammer toe.

Abstract: 1,262,284. Telecine equipment. AGFAGEVAERT. 17 Feb., 1969 [13 March, 1968], No. 12244/68. Heading H4F. [Also in Division G2] A multicolour subject is telecast for viewing on a television receiver by producing a photographic colour film of said subject, scanning the film image to obtain electronic image signals and amplifying and transmitting said signals, the photographic light-sensitive colour film and the conditions of its exposure and development being such that each of the colour component images produced on the film has a gamma between 0À45. and 0À7, a maximum density of not more than 2À2 and a contrast, measured in terms of log opacity difference, within the range 1À0 to 1À35. Colour films bearing images of these characteristics are not capable of giving satisfactory images by ordinary cinema projection but provide a more acceptable colour picture on the tube of a television receiver without any need for substantial electrical gamma modification on transmission. The colour films may be of the colour reversal type or may be positive film produced from colour negative material or by dye-inhibition printing. The colour images may be corrected by integral colour masks.

[Class 136 (iii)] An adjustably resilient handle-bar for cycles has a rubber or like layer A, B bent round and vulcanized to the middle portion 11 of the handle-bar 12 and has enclosing the layer, and also vulcanized thereto, a split tube C, D. Surrounding the tube C, D is another split tube E, F, preferably of stouter gauge, and this latter is gripped in the usual bolt-contracted clamp on a goose-neck carried by the steering- post. The tube portions C, D are dimensioned so that under the maximum pressure exerted by the clamp bolt they do not meet, and in the gaps between them are located beads 23 pressed in from the outer tube portions E, F. These beads position the gaps between the portions E, F at locations apart from the gaps between the portions C, D, and serve also to impart a positive non-rotational hold, through the vulcanizations, between the tube E, F and the handle-bar. The portions E, F may meet at the edges under maximum clamping to limit the degree of rigidity impartable. The portion 11 is preferably of reduced diameter to allow of employment with normal clamps.
