Title: Tow-forming apparatus
Inventor: EDNEY BARRY JAMES
IPC: D04H3/105
Filed: 1964-09-10
Abstract: 1,108,632. Tow forming; filament guides; non-woven fabrics. DUNLOP CO. Ltd.  Sept., 1965 [10 Sept., 1964], No. 37014/64. Headings D1D, D1F and D1R. Apparatus, for forming a tow from one or more sheets of textile yarns or filaments comprises a pair 1, 2, 3 or 4 of parallel lease rods (6, 7) (Fig. 2 not shown) mounted parallel to a diameter of a rotatably adjustable circular carriage 5. the plane of the carriage being perpendicular to the sheet or sheet of yarns or filaments. The yarns or filaments are passed between the rods of a pair and by rotatably adjusting the carriage 5, the width of the tow issuing therefrom can be selected. The rods (6, 7) Fig. 2, are bent and joined so as to have common mounting elements 10, 11. These are rotatably received in blocks 12, 13 mounted on the carriage 5 and may be locked in an adjusted position by screws 15 such rotation causes the filament path to be more or less sinuous and thus adjusts the tension of the filament passing through the bars. More than one pair of rods may be provided, e.g. four pairs, each pair producing a separate tow. Carriage 5 is rotatable on a plate 16 adjustably mounted between side plates 20. 21. In Fig. 3 (not shown) tow from the lease bars is converted into a felt by rollers (50), spreader 51, infra-red heaters (52) to relax the material and needling apparatus (57, 58. 59, 60). Suitable filaments for the felt are crimped poly(ethylene terephthalate) or filaments which have a potential crimp which may be brought out e.g. by application and subsequent removal of a wetting agent, e.g. rayon having an unbalanced skin structure or nylon having disulphide and polyalkylene sulphide cross-links. Another suitable filament is rayon which can be crimped by cross-linking, e.g. by using a resin or steam-setting treatment in place of a heat setting treatment.

Abstract: 368,737. Manoeuvre signalling apparatus for use on road vehicles. WELLS, G. P., 17, Orchard Road, Anlaby Park, Hull. Dec. 9, 1930, No. 37076. [Class 118 (ii).] A manoeuvre signalling apparatus for use on road vehicles comprises a pedal which has the ordinary motion for actuating brake, clutch, or throttle mechanism and which has a lateral motion for actuating the signalling apparatus. The pedal is connected to a rod A which is connected by a ball-and-socket joint B with the lever Q connected to the brake &c. mechanism. The rod A passes through a slot C in a plate C<1> and lateral movement given to the pedal through pressure on one of the plates A<1> causes the rod A to deflect the forked arm D pivoted at X to cause the contact blade F on the arm to effect contact between one or other of the pairs of contacts J<1>, L<1> and J2, L<2> to actuate the signalling apparatus T or S. The contacts J<1>, J2 are connected to a common terminal K and the contacts L<1>, L<2> to terminals M<1>, M<2> respectively. V is a master switch for disconnecting the connections when required. The arm D has mounted on it a spring-loaded ball-catch G which registers with one of three depressions in the plate C<1>. The underside of the plate C<1> carries a projecting bracket P on which is mounted the lever Q, R being a spring. The ordinary and lateral movements of the pedal can take place independently or can be combined. Fig. 4 shows how the pedal and switch can be fitted to a clutch or brake lever, the switch being mounted on a bracket E secured to the clutch housing T<1>, and the laterally moving pedal rod A swivelling on the ball joint B secured to the top of the clutch or brake lever S<1>. An alternative construction is described with reference to drawings in the Provisional Specification.

Title: Directional aerial systems consisting of a plurality of electrically subdivided individual aerials
IPC: H01Q21/08
Filed: 1957-11-29
Abstract: 866,930. Aerials. TELEFUNKEN G.m.b.H. Nov. 29, 1957 [Nov. 30, 1956], No. 37310/57. Class 40(7) An aerial array consists of a number of slender linear, vertical aerial elements electrically subdivided along their lengths and having the gaps at the dividing points bridged by resistors. The purpose of including the resistances is to reduce the interaction of the elements one upon another so that the input resistance of each element can be maintained substantially constant over a wide frequency range and so that the resultant polar diagram of the array can be determined with reasonable accuracy by summing the effects of the individual elements. These advantages outweigh the loss of energy in the resistors for some applications, particularly for reception and the losses at the lower frequency end of the working range can be reduced by shunting the resistors with inductors. In an embodiment having two elements each subdivided into parts 2 and 3 the parts are coupled by resistors 5 shunted by inductances 7. At the upper end of each element there is provided a capacitive top-loading 1 coupled to the element through an inductor 6 and resistor 4. The lower ends of the elements are coupled by transformers 8 to feeder 9 which is in turn connected to radio equipment 34 by transformer 33. A suitable choice of values for the components 4, 5, 6 and 7 will give a substantially constant input resistance over a wide frequency range. Arrays according to the invention may be constructed with any number of elements positioned, and with their feeders phased, to give a required directive pattern.

Abstract: 1328373 X-ray apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 Aug 1970 [12 Aug 1969] 38149/70 Heading H5R [Also in Division G2] In an arrangement for preventing double exposure of a portion of an X-ray film in apparatus in which the insertion of different diaphragms into the X-ray beam, combined with a corresponding sequence of movements of the cassette, permits successive exposure of different portions of the film, a code signal is produced in accordance with the diaphragms inserted in the beam, the film portion positioned for exposure, and the film portions already exposed, which signal is compared with the signals associated with the previously exposed portions of the film, a coincidence with any of which signals serves to prevent exposure of that portion of the film. As described, the apparatus includes an electrical network which combines binary signals corresponding to the film or cassette size, the inserted diaphragm, and the number of exposures already made, and a coincidence circuit for comparing the result with the signals corresponding to previous exposures, which are retained in a store; depending upon whether or not a coincidence is recorded, the exposure is prevented-so that the cassette has to be moved, or is automatically moved by the coincidence signal, to the next of its sequence of positions, whereupon the process is repeated- or the exposure takes place and the signal passes to the store. The apparatus may further provide an optical indication of the state of the film by use of an illuminated panel having a white and a red lamp corresponding to each section of the film positioned for exposure by movement of the cassette into its successive positions, the white lamp being energized by a signal from the network to indicate that film portion which is next in order for exposure, and the red lamp being energized by the store to indicate that that portion has been exposed. Alternatively, the display may employ a television screen. Radiation restricting diaphragms referred to include those of oesophagus type, dividing the field into two or three portions in the direction of width, and a compression tube for restricting the field both in width and in height.
