Abstract: 1,210,213. Light guides. FOSTER WHEELER JOHN BROWN BOILERS Ltd. Nov. 28, 1967 [Nov. 28, 1966], No. 53241/66. Heading G2J. A light guide in the form of a rod 12, Fig. 1, of transparent material having a different refractive index from the medium in which it is to be used has at its viewing end 17 a planar polished face transverse to the rod axis and at the other end an inwardly projecting conical polished face 16 the axis of which coincides with the rod axis. The device has particular application in the inspection of cavities or regions of bores of tubes especially those of small diameter. To view, for example, a weld 18 the enclosed angle α of the conical face 16 is less than 90 degrees and preferably 80 degrees, the face 16 acting as a reflecting prism. Where it is desired to look through the conical face 16 the angle α may lie between 100 degrees and 180 degrees but is preferably 120 degrees. Preferably the planar viewing face 17 is formed on a cylindrical projection 28 of less diameter than but coaxial with the main body of the rod 12. The projection 28 is joined to the body by a frusto-conical face 30 through which light, e.g. from a lamp, enters the rod to illuminate an object to be viewed. In an alternative embodiment, Fig. 5, the viewing end of the rod comprises an inner upwardly projecting conical face 82 of internal angle less than 90 degrees and an outer annular frusto-conical face 84 of a closed angle greater than 90 degrees, whereby two images are seen simultaneously. The face of the conical projection may be given a reflective coating. Suitable materials for the rod are glass, quartz and synthetic organic polymeric substances. The rod may be of annular, square or oval cross-section.

Filed: 1974-11-14
Abstract: 1480346 Assembling recessed tools TUBE WINDING (PAPER) CO Ltd 14 Nov 1974 [21 Nov 1973] 54062/73 Heading B8T Apparatus for assembling a preferably fibre-board recessed lid, having a tray 31 fitting in a cylindrical ring 30, comprises means for applying a strip of adhesive to the inner face of the ring and means for inserting the tray, tray walls foremost, into the ring a sufficient distance for the outer face of the wall of the tray to contact the adhesive. Adhesive is applied through an applicator 36 fed from a source 38 to the inner face of the ring by rotating the ring 30 on a rotating wheel 33, with ring and wheel axes horizontal, a freely rotating pressure roller 35 contacting the inner face of the ring. The applicator 36 and roller 35 are respectively mounted on blocks 39 and 40 which can be moved upwards on supports 41 and 42 so that the ring can be removed from the wheel (Fig. 3). The ring is then transferred via a shoot to a circular indexing plate 17 with preferably six equi-spaced identical circular apertures lying equidistant from the centre of the plate, the ring being pressed into the collar 32 surrounding an aperture. A tray 31 is simultaneously fed to the other side of the plate 17 and is pushed by pusher plate 13 through guide ring 47, which has a convergent circular inner cross-section to reduce the outside diameter of the leading edge of tray 31 to that of the aperture and inner face of ring 30. Pusher plate 12 holds ring 30 in the collar 32 as the tray wall is inserted in the ring to contact the adhesive (Fig. 6). An indexing gear-box, which actuates all the ancillary equipment associated with the indexing plate, now removes plates 12 and 13 and rotates the indexing plate through 60 degrees from the first stage to the second stage of assembly where the adhesive is allowed to dry while another ring and tray are assembled in the aperture now in the first stage. At the third stage, after a further 60 degree rotation, a pressure plate supports the base of the tray and, in the collar side of the indexing plate, a heated forming head moves to contact the projecting portion of the ring to turn it over and inwards to form a bead 53. After rotation through 180 degrees, an ejector plate 16 moves in the direction of arrow 54 (Fig. 8) to eject the completed lid from the indexing plate.

Title: Transmitters for conductor identification in multiconductor electric cables and systems and methods employing same
IPC: H04M3/22
Filed: 1973-11-28
Abstract: 1494894 Selective signalling POST OFFICE 20 Feb 1975 [28 Nov 1973] 55203/73 Heading G4H A shift register enables a plurality of gating circuits to pass oscillator bursts of different durations respective to the gating circuits. One of a plurality of conductors (or pairs of conductors) is identified by applying to each conductor a burst signal of duration unique to that conductor and at a receiver identifying a conductor in response to the duration of the signal on it. An oscillator (of higher than specch frequency) drives a shift register via a divideby-16 circuit to enable progressively more of 20 gates (i.e. the first, then the first and second, then the first, second and third, and so on) to pass the oscillator output rounded to a sinusoid to 20 conductors respectively (e.g. conductors in a telephone cable), the sequence being repeated after a delay. A remote receiver is connected to one of the conductors to be identified, the signal being filtered, squared then sent in parallel to a noise discriminator and counter means. The counter means consists of a divide-by-16 counter (which initially divides by 12 instead in view of possible loss of signal due to momentary line breaks) feeding a BCD counter. The noise discriminator starts with a retriggerable monostable with a period just longer than two cycles of the oscillator to detect the signal and ignore noise spikes. At the end of the signal it enters the count in the BCD counter into latches then resets both counters. The latch contents are decoded to drive a gallium arsenide 7-segment display, the decoder being disabled when no repetitive signal is being received.

Title: Device for checking registration of an amount of money in money dispensers
IPC: G07F7/00
Filed: 1972-12-06
Abstract: 1407704 Money dispensers GLORY KOGYO KK 6 Dec 1972 [6 Dec 1971] 56356/72 Headings G4X and G4H A money dispenser comprises a register 1 for storing data representing the amount of money to be dispensed and a comparison section 7 for determining whether this amount is an integral multiple of either the denomination of money selected or, if the dispenser is set to dispense the amount with the minimum number of pieces, the lowest available denomination of money. The embodiment shown is a banknote dispenser for 10,000; 1,000; and 100 yen notes. The amount to be dispensed is entered via a registration section 2, e.g. a ten key keyboard, into a six digit, four bits per digit, shift register 1 and is read out, starting with the least significant digit by the application of timing pulses t 1  to t 4 , the digit stores M 2  to M 7  during the timing periods of timing pulses T 2  to T 7  respectively. Function keys 5a to 5c which set stores 6a to 6c to produce signals Tt, Ot, Oh are provided for selection of 10,000; 1,000 and 100 yen notes respectively. The "10,000" signal Tt is applied to one input of AND gate G 14  the other input of which receives timing signals T 2  to T 5  via an OR gate G 11  and the output of which is applied via an OR gate G 17  to AND gate G 18 . AND gate G 18  receives at its other inputs the output Sd of the shift register and a signal EQ produced when registration of the amount to be dispensed is terminated and will therefore produce a blocking signal CH if 10,000 yen notes have been selected but the lowest four digits of the amount entered are not all zero. The OR gates G 12 , G 13  associated with the 1,000 and 100 notes receive as inputs the timing signals T 2  to T 4  and T 2 , T 3  respectively and the blocking signal CH is similarly produced if the entered amount cannot correctly be dispensed in the selected denomination. If the dispenser is operating in the minimum possible number of banknotes mode a signal is applied to the "100" line Oh. In another embodiment (Figs. 1 to 4, not shown) 5,000 and 500 yen notes are also dispensed there being circuits (L), (7d) and (7e) for determining whether the relevant digit of the entered amount is five or zero. In further embodiments (Fig. 6, 7, not shown) the amount entered is stored in a static register the digits of which are evaluated either sequentially (Fig. 6) or simultaneously (Fig. 7).

Title: Data memories
IPC: G11C19/00
Filed: 1970-12-03
Abstract: 1315530 Data storage INTERNATIONAL BUSINESS MACHINES CORP 3 Dec 1970 [31 Dec 1969] 57385/70 Heading G4C A data memory has a plurality of memory elements in each of which data can be electronically circulated under electronic control, addressing being by decoding to energize a first group of memory elements at a first location corresponding to the address and a second group of memory elements corresponding to a location bearing a predetermined relationship to the first location and by comparison with the current position of the data in the energized elements. The invention is described as a modification of that in Specification 1,315,528 (referred to) which has a plurality of memory cards each having a 2-dimensional array of recirculating shift registers, a word consisting of a bit in each card, and a word being accessed by X and Y co-ordinate selection of the relevant shift register in each card and recirculating of these registers until a specific address counter indicating their recirculation position reaches the required value. A series of adjacent words can be read/written in turn, the selected shift registers then being recirculated until the specific address counter equals a general address counter indicating the recirculating position of the non-selected shift registers. In order to save time in accessing multi-word records involving more than one adjacent shift register in each plane, the present invention has the even and odd numbered shift registers in separate arrays on each card and when any shift register, the nth say, is selected on a given card, so is the (n+1)th, but only the nth is connected for read/write. A word position address specifying the required word in the shift registers used for read/write at any given time, is compared with the specific address counter, equality causing read or write. The word position address is then incremented, and since the specific address counter is also incremented with the next shift of the registers during the recirculation, successive words are accessed. When the word position address reaches its maximum possible value (indicating that the next word is in the next shift register, viz. the (n+1)th on each card), switching of an odd/ even trigger connects the (n+1)th shift registers for read/write and disconnects the nth shift registers (but both remain selected). When the specific and general address counters are equal (indicating that the nth registers have been returned to the recirculation position of the non-selected shift registers), the portion of the address specifying the required shift register, viz. the nth shift register, is incremented so that the (n + 1 )th and (n + 2)th shift registers are now selected in each plane, and so it continues until the whole of the multi-word record has been accessed. Finally, recirculation of the last shift registers involved continues until the specific and general address counters are equal. Regeneration is done as in the Specification referred to above.
