Title: Improvements in or relating to the Examination of Containers for Dirt or other Foreign Matter
Inventor: GILES PETER MICHAEL
IPC: G01N33/00
Filed: 1966-02-28
Abstract: 1,182,413. Photo-electric container inspection. P.M. GILES. May 26, 1967 [Feb. 28, 1966], No.8697/66. Heading G1A. To detect foreign matter in containers, the inside surface of a container is scanned with a narrow beam of radiation such that the container fluoresces and any matter marks the fluorescent radiation or the matter fluoresces and the container does not fluoresce or both container and matter fluoresce but at different wavelengths. The scanning radiation may be infrared or ultraviolet radiation. In one arrangement Fig. 1, where the container 20 is stationary, radiation from a source 10 is directed down the centre of a probe carrying a mirror 18 to deflect radiation to the inside of the container. The probe comprises an outer cylinder 16 forming part of a worm drive 21, 22 and is keyed to an inner cylinder 15 driven by motor 25 so that the mirror 18 rotates and is lowered into the container which is thereby scanned in a helical path. The mirror 18 is adjustable to scan the base of the container. Fluorescent radiation returns up the probe to be deflected by a halfsilvered mirror 14 on to a dichroic mirror 26 which directs fluorescent radiation from the glass on to detector 28 and fluorescent radiation from any foreign matter on to detector 27. A signal from 27 or alternatively no signal from 28 operates a delay circuit 32 to reject the container. In another arrangement Fig.2 (not shown) the container is rotated and the inside surfaces scanned by a flying-spot scanner.

Title: Telecommunication, particularly Telephone Exchange Systems
IPC: H04Q3/00
Filed: 1968-02-22
Abstract: 1,194,934. Automatic exchange systems; logic circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 22 Feb., 1968 [24 Feb., 1967], No. 8749/68. Headings H3P and H4K. In a route simulating network used for route selecting in an exchange employing cascaded matrices of switching devices, each guide wire link of the network incorporates a potential divider controllable from either end of the link to vary the magnitude of the voltage applied to the link. In the Figure only one complete link ZL between " offering " amplifiers AV-I and AV-II is shown. An offering signal applied initially at the left-hand side of the network passes through the network from left to right via all links corresponding to available routes through the network. At each stage a relay AN (shown as a contact-making relay) in an offering amplifier such as AV-I operates opening a contact (or the electronic equivalent) and disconnecting the ground potential which is normally applied to the links such as ZL leading from that amplifier. This allows the potential of each link ZL to rise to a potential determined by a potential source, a resistance RA1 connecting it to the link and the input resistance of the offering amplifier AV-II connected to the right-hand end of link. These potentials are the same as the offering signal and propagate through the amplifiers AV-II and succeeding amplifiers in similar manner until they arrive at the right-hand side of the network. The amplifiers (Fig. 2, not shown) are in fact transistorized and include a first transistor which is switched to conduction by the offering potential and blocks a second transistor normally supplying earth potential to the output links. When offering signals arrive at the right-hand side of the network one is selected (e.g. at random if the switching network connects a calling line to a register) and the amplifier associated with the last link (say the amplifier AV-II) is disconnected from the links from earlier stages by opening an associated contact ZU (or electronic equivalent) in the marker ZM. The potential on the links so disconnected rises to the potential supplied via the resistance RA1. With the contact an of the preceding amplifier AVI still open this higher or access potential passes to a common terminal i leading to an AND gate of an array associated with a threshold indicator SW1 common to all links. The AND gates are enabled first a row at a time and then individually by row and column select circuits AZ, AS to detect first a row and then a gate and thus a link associated with the higher or access potential. This information is used to select a link of the preceding stage, and so on until a unique route is selected. The contacts Z U in the marker used for this selection are in fact a second set of AND gates scanned by the select circuits AZ, AS.

Abstract: 479,320. Door latches. YALE & TOWNE MANUFACTURING CO. April 5, J937, No. 9566. Convention date, June 17, 1936. [Class 44] In a night latch, the bolt has holding means adapted to assume a dead centre relationship when the bolt is fully projected into a, striker by the latch spring, together with an auxiliary spring-loaded bolt which when shot holds the holding means out of dead centre and permits of latching the bolt. The latch bolt body 16 is outwardly urged by a spring 17 mounted in a bore 18 and about a pin 19 located in the hole 20. The bolt is retracted by a U-shaped cam 26 connected to the body 16 by a bar 23. Located alongside the latch 16 and mounted for sliding along it is an auxiliary bolt 38 to which is attached a lever 40. This lever has a cam surface 41 which, when the auxiliary bolt is shot, lies underneath the portion 31 of the bar 23. When the nose 33 encounters a striker 37, the latch bolt and auxiliary bolt are retracted but when the latch bolt enters the striker the auxiliary bolt is left retracted, Fig. 6. This causes the cam surface 41 to be removed from underneath the portion 31 and allows the latch spring 16 and the spring 30 to force the lever 23 downwards and the pivot points 24, 25, 26a into a dead centre relation making the bolt 33 into a dead bolt. The bolt may be retracted by actuating the U-shaped cam through bar 63 which is operated either by a handle 61 or cylinder lock 62. The bolt may be held retracted by the slide plate 66 which co-operates with a detent member 67. The latch head 33 is separate from the latch body 16 and is attached thereto by a neck 36 which slides in a slot 34. The opening in the front plate 15 prevents movement in the direction of the slot 34. The latch is connected rigidly to the handle and cylinder lock by the bolts 68 which pass through ears formed on the casing 10. The Specification as open to inspection under Sect. 91 describes a modification in which the U-shaped cam 26 and bar 23 are applied to a dead bolt. This subject-matter does not appear in the Specification as accepted.
