Title: Opto-electrical checking of packages
Inventor: WILLIAMS CHARLES RICHARD
IPC: B07C5/34
Filed: 1983-10-31
Abstract: To check whether goods have been correctly packaged, each package P is brought into a specific position relative to an image transducer 23 or 33 by means of slide 20 or 30 and stop plate 21 or 31. By means of two image transducers 23 and 33 both end-faces of the package may be scanned in vertical lines during its movement. The information provided by the images, divided into grey levels and converted into digital impulses at 40 and 41, is compared at 42 and 43 with stored image data from 44, and this comparison is used by a processor 45 for determining whether the end folds of the package are defective. Rejected packages are removed from the conveyor line by means of an ejector 16. Pulses from a transmitter 15 on the conveyor are used at 46 to synchronise the image comparison with the packages. <IMAGE>

Title: Telephone line voltage detection circuit
Inventor: REVELL DENNIS WILLIAM
IPC: G01R19/155
Filed: 1984-09-04
Abstract: A line voltage detector, especially (but not solely) for use in a telephone exchange of the TXE4 or TXE4A type uses a set of four operational amplifiers (OA1 to OA4) to detect line conditions, i.e. on hook/off hook and dialling. One amplifier (OA1 ) is resistively coupled to the line so that its output reproduces line voltage changes, and its output goes to another amplifier (OA3) which acts as a bidirectional integrator. Another amplifier (OA2) is zener diode (D9-D10) controlled to produce a reference voltage for the integrator amplifier (OA3). This reference voltage is also applied to an input of a fourth amplifier (OA4) used as a comparator, whose other input is from the integrator amplifier (OA3). The output of the comparator thus suitably modifies line voltage changes, is fed via further transistors (TR21, TR27, TR28) to the circuit's output. <IMAGE>

Patent GB-2168573-A (GB)
Title: Packet switched system
Inventor: WALSH WILLIAM ARTHUR GEORGE
IPC: H04L9/12
Filed: 1984-12-13
Abstract: End-to-end encryption of traffic in packet networks presents difficulties due to the discontinuous nature of the data. In the present method these difficulties are overcome by sending an initialisation variable (IV) during the initial call setting and controlling the clocking information such that at each end the clock for the encryption or decryption is started at the beginning of the information field and stopped at the end thereof. Thus when the next packet is sent, both cryptos are correctly set. This avoids the need to send such information with each packet, as called for in some known systems. <IMAGE>

Title: Personal inductive coupler apparatus
Inventor: BUCKLEY GORDON
IPC: H04B5/00
Filed: 1985-05-22
Abstract: A housing 10 enclosing an inductive coupler coil is connected to a headband 14 of flexible material. The coil is connected via an electrical lead 12 to a plug which in use is inserted into an isolated socket of a television or radio set or other sound-producing equipment. A person who wears a hearing aid places the headband 14 on his/her head so that the housing 10 is close to the ear with the hearing aid and switches the latter to the 'telecoil' position. Sound from the set or equipment is then received without interference or background noise and the headband arrangement is more comfortable and readily adjustable than previous inductive coupler equipment. For users who wear hearing aids in both ears, a headband having inductive coupler coils in respective housings at each end is provided, the coils being connected to each other through the headband. <IMAGE>

Title: Coaxial cable plug
Inventor: CALEARO MASSIMO
IPC: H01R13/646
Filed: 1986-09-24
Abstract: The present invention relates to an improvement in the construction of connector plugs for coaxial cables for car radio aerials, particularly suited for being connected to the coaxial cable by means of an automatic fitting. According to the invention, the connector plug is formed by a small insulating tube 10, which is essentially cylindrical and hollow inside, by a plug-in socket 14 which is inserted into the small tube and electrically connected to the central wire of the coaxial cable, and by an external thin metal sheet 30 surrounding the small tube and locking the cable and the braid in the terminal part. The external thin metal sheet is equipped with one or more fins 35, 36 obtained by cutting out the thin metal sheet itself and which are arranged in space in such a way that, when the connector plug is connected to the coaxial socket, the resultant of the elastic reaction forces is not zero and such that it produces a subsequent contact between the cylindrical part of the connector plug and the cavity of the socket. <IMAGE>

Title: Improvements relating to apparatus and methods of transferring heat
Inventor: MORAN ARTHUR WILLIAM
IPC: A23L5/10
Filed: 1987-04-15
Abstract: The present specification discloses a heat transfer device (1) for use in transferring heat to or from a material. The heat transfer device (1) provides an elongate hollow body (3), preferably in the form of a needle, with an elongate inner duct member (5) extending through said body (3). Heating or cooling fluid can be passed along the inner duct member (5) and back along the gap (15) between the body (3) and the inner duct member (5), and by piercing the relevant material, the material can be heated or cooled from the inside out. This thus reduces the heat barrier problem referred to and allows the heating or cooling to be effected relatively quickly and more efficiently. <IMAGE>

Title: Heated printing type assembly
Inventor: ANDERSON PATRICK HARVEY
IPC: B41K3/60
Filed: 1989-05-24
Abstract: An assembly for intermittently marking surfaces, such as packages and packaging materials, includes an ink supply means which engages with type elements 14 as the latter move from a rest position, Fig. 2, in which the type is heated, to a printing position, Fig. 4, but which does not engage the type elements as the type elements return from the printing position to the rest position. The type elements 14 preferably comprise rubber, and are heated in the rest position on a stationary anvil 76. The ink supply preferably comprises an ink roll (82), Fig. 1, rotatably mounted in an oven 96. Pneumatic cylinders 58, 94 are provided to move a type holder from the rest position to the printing position and vice versa, as well as for moving the ink supply means into and out of the path of the type holder. The assembly is particularly useful for providing a date stamp; by using thermoplastic ink and heated type, smearing of the impression is minimised: the avoidance of contact with the ink supply on the return stroke prevents unwanted build-up of ink on the type face. <IMAGE>
