Title: Electric immersion heaters
IPC: H05B3/04
Filed: 1980-04-01
Abstract: The head of an immersion heater has a screw-threaded portion (10), for securing it in place, with a circular end plate (11) at one end for supporting heating elements and an outwardly directed shoulder (13) at the other end. A polygonal flange (14) stems from the shoulder and has an inturned strengthening lip (15) with diametrically opposed lugs (16 and 17), the larger of which (16) carries a screw-threaded rod (18). The cover has a top (20) and a depending skirt (21). A marginal portion (23) of the skirt is of polygonal shape and fits within the lip (15) to make it difficult to insert a tool for levering off the cap. The smaller lug (17) projects through a hole (24) in the skirt to anchor the cap in place, while a hole (25) in the top of the cap enables a retaining nut to be screwed onto the rod (18). <IMAGE>

Title: Machine safety device
IPC: B23K11/31
Filed: 1981-02-20
Abstract: Device for preventing the application of full working force used to move a pair of co-acting elements into an operating relationship, e.g. the electrodes of a spot or resistance welding machine, except in a defined zone of their path of relative travel including said relationship, the effective width of said zone in said path being too small, e.g. 6mm wide, to allow an operative's finger or other part of the body to be trapped under full force. The zone position is adjustable and a pneumatic control circuit (Fig. 1 not shown) is described including the provision of controlled cushioning pressure to regulate the descent of a ram piston by gravity. The zone may be defined by the width of a control member 44a or of a gap, groove or aperture therein which co-acts with a proximity sensor 23 of the control circuit. <IMAGE>
Patent GB-2075373-A (GB)
Title: Applying additive to tobacco
IPC: B05B7/32
Filed: 1981-04-14
Abstract: An apparatus which sprays atomized water, casing, plasticizer or another liquid additive onto a stream or tow of tobacco or filter material has one or more single-material atomizing nozzles (11) which receive additive from a pump (16) by way of a first conduit (13) which contains a check valve (22) between the pump and the junction (13a) with the discharge end of a second conduit (19) serving to supply compressed air when the pressure of additive does not suffice to ensure a reliable atomizing action. The second conduit (19) is connected to a source (23) of compressed air and contains a check valve (21) which is closed by additive when the latter is maintained at normal pressure. When the pressure of additive drops, such as immediately after starting or on stoppage of the pump, compressed air opens the check valve in the second conduit (19), closes the check valve (22) in the first conduit (13) and expels the additive from the first conduit (13) into the nozzle or nozzles (11) at a pressure which suffices to ensure a satisfactory atomizing action. <IMAGE>

Patent GB-2099761-A (GB)
Title: Luminescent address bar codes
IPC: B07C3/18
Filed: 1981-05-21
Abstract: A luminescent address bar code is applied to a predetermined location of a postal item at an early stage in its handling by the Postal Authorities to provide in a machine readable form the destination address written on the postal item. This machine readable bar code is then sensed and used to route the postal item in automatic sorting machines. Errors in the reading of the luminescent address bar codes leads to the postal item being misrouted or being rejected. The quantity of light emitted from the luminescent address bar codes varies with the nature and properties of the surface of the postal item and it is this variation in the quantity of light emitted which leads to errors in reading the codes. To overcome this the reflectance of the surface of the postal item is monitored and then the quantity of fluorescent or phosphorescent material applied to the postal item to form the bars of the address code is controlled in dependence upon the reflectance of the postal item, so that the visible light emitted from the code bars on every postal item is substantially constant.

Title: A magnesium-containing Ziegler-Natta catalyst component
IPC: C08F10/00
Filed: 1981-12-23
Abstract: It has been found that the conventional step of drying support materials to remove residual absorbed water before reaction with other catalyst components can be omitted for components based on diorganomagnesium compounds and transition metal compounds. Satisfactory olefin polymers are still obtained by this simplified and cheaper procedure, with enhanced bulk density for polyethylene in some cases. Organoaluminium compounds and polar additives may be included in the supported component.

Title: Serial bus interface unit
IPC: G06F13/42
Filed: 1982-03-04
Abstract: A mechanism is provided for the distribution of data and commands between microprocessors and/or non- intelligent electronics modules. In applications requiring a high level of reliability it is often necessary to provide for spare electronics modules to be put into service to replace faulty modules (redundancy switching). The use of microcomputers in high reliability applications has created a problem in providing redundancy switching using conventional cross-strapping techniques because of the large number of wires (typically 40) that make up a microcomputer interface. The interface unit reduces the number of cross-strapped interconnections by converting any parallel data highway (for example that of a microcomputer) to a serial digital time multiplexed highway which uses a regular clock signal and a data transfer line. It performs all data synchronisation, address detection, serial to parallel and parallel to serial conversion functions, bit counts and interrupt control required for communication between microcomputers and/or non-intelligent electronics modules.

Title: Production of foot and mouth disease vaccine from microbially expressed antigens
Inventor: YANSURA DANIEL G
IPC: C07K14/09
Filed: 1982-06-11
Abstract: Polypeptides which act as antigens of foot and mouth disease virus (FMDV) are produced by microorganisms which have been transformed with plasmids produced using recombinant DNA technology. A suitable plasmid has a gene sequence (produced by chemical synthesis or by reverse transcription) which encodes a polypeptide comprising one or more immunogenic determinants of one or more FMDV proteins, and optionally a fusion protein preferably linked via a cleavage site, the gene sequence being under the control of a promoter. For example, an E. coli K12 strain was transformed with plasmid pFM1. This is based on plasmid pBR322, with the DNA sequence of codons 8 to 210 of the VP3 gene of FMDV type A12119ab connected to the LE' protein (from pBR322) so as to be in the same reading frame. This assembly is under the control of the E. coli trp operon. The transformant E. coli was cultured and caused to expressthe LE'-VP3 fusion protein. This was isolated and shown by competitative radio immunoassay to have similar antigenic properties to purified natural VP3 protein.

The expandable construction is particularly suitable for an abrasion tool and may have abrasive particles secured to the cutting section. In another embodiment, the abrasive stones (100) are adjustable along inclined bottom surfaces of recesses (94) and fixedly secured in their adjusted position by wedge-shaped clamps (104). <IMAGE>
