Title: Call coin-box telephone instrument
IPC: H04M17/02
Filed: 1980-10-16
Abstract: The call-coin box telephone instrument consists of a micro- processor controlled coin and fee checking and call administration arrangement using electronic coin validation techniques. The instrument includes anti-fraudulent measures to prevent simulation of MF4 signals. It is possible for the MF signals necessary to set-up a call to be pre- recorded on a tape recorder and for that recording to be injected into the line using the microphone of the instrument. Under such circumstances the call administration processor of the instrument assumes that the handset was off normal and the instrument is receiving dial-tone. However, the exchange equipment would respond to the simulated MF signals and a call could be set-up without the instruments, call processor responding at all. To prevent such a situation for each call, the microphone is short circuited until the shortest valid dialling code (normally three digits) has been dialled.

Patent GB-2101215-A (GB)
Title: A position controller
Inventor: BAUMGARTNER HANS
IPC: F02M26/48
Filed: 1982-06-04
Abstract: The controller has a diaphragm box comprising a spring-biassed diaphragm rod (20). The pressure prevailing in a control pressure chamber (S) of the box is controlled by the provision of two electromagnetic valves (34, 36) in the box which reduce delays in response and line losses. In addition, the valves and the control pressure chamber are designed to have the least possible dead space. In order to obtain optimum resolution, the diaphragm rod guide (22) which is preferably based on polytetrafluoroethylene, provides the least possible difference between static and sliding friction. The valves are preferably mounted firmly in receiving pockets (38, 40) and are in the form of quick-response, low- mass hinged armature valves. An electromechanical position repeater (46) coupled for movement with the diaphragm is integrated with contact springs in the diaphragm box and is also mounted in a receiving pocket (48). <IMAGE>

Title: Construction of dna sequences and their use for microbial production of proteins, in particular human serum albumin
Inventor: LAWN RICHARD M
IPC: C12N15/00
Filed: 1982-08-25
Abstract: By means of reverse transcription of mRNA coding for a desired polypeptide, there is obtained a set of overlapping fragments of duplex cDNA, which together correspond to the whole mRNA molecule. The fragments have overlapping regions bearing sites for restriction enzymes, such that cutting and ligation gives DNA corresponding to the polypeptide. This is introduced into a vector in reading frame with a promoter. Transformation of a microorganism enables expression of the polypeptide. The construction via fragments enables large molecules to be made. Thus, human serum albumin (HSA) is produced by E. coli transformed with plasmid pHSAI. This includes DNA made from fragments derived from reverse transcription of mRNA from human liver.

Patent GB-2109165-A (GB)
Title: Trip solenoid
Inventor: MYERS JOHN L
IPC: H01F7/08
Filed: 1982-04-19
Abstract: Trip solenoids commonly employing an axially oriented holding magnet which is positioned in the space between a portion of the frame and a fixed pole. Commonly the pole is provided with an annular portion, terminating in proximity to the frame defining an air gap therewith, to provide a shunt path which is commonly not adjustable. Additionally, since the holding magnets are usually formed of cobalt they are relatively costly. The present invention is directed to a trip solenoid which is adapted to employ low cost magnets and to provide a variable gap in a secondary or shunt circuit. Preferably, this gap is made variable by suitably selecting the thickness of a shim or spacer of non-magnetic material. The electric trip solenoid employs a pair of low-cost retaining or holding magnets (40, 41) in an open frame arrangement in which the magnets are positioned on opposite sides of the flat surfaces (33, 35) of a pole (30) and in contact with the pole and the legs of an open frame (10). The magnets are thickness oriented so as to distribute their flux through relatively large areas avoiding regions of high flux density. The variable gap is provided by means of non-magnetic shims (55).

The door is released by pushing it further inwards. A second embodiment shows a pivoted keeper directly engaging a heart-shaped groove, with a sprung plunger urging the door outwards. This too is released by inward pressure. <IMAGE>
