Title: Bicycle or wheelchair propelling device
Inventor: WESTON PAUL ANDREW
IPC: B62M7/14
Filed: 1985-06-26
Abstract: A bicycle propelling device has a chassis 1 fitted with a wheel 2 driven by an electric motor 8. The electric motor 8 and a battery are mounted on the chassis 1. The chassis 1 is journalled onto a hinge 3 attached to the bicycle. The axis of the hinge 3 is parallel with the axis of rotation of the bicycle rearwheel. The hinge 3 is releasably attached to the bicycle. The bicycle propelling device is readily demountable from the bicycle. Forces and couples acting on the bicycle due to the mass of the propelling device may be reduced to a minimum by choice of chassis 1 and other dimensions. The electric motor 8 is coupled to the wheel 2 by a belt and pulleys. The electric motor may be replaced by an engine. The propelling device may be used with a tricycle or a wheel chair. <IMAGE>

Title: Improvements in sealing devices for use in gas disposal or recovery systems
Inventor: COLLINS GRAHAM JAMES
IPC: F16K13/10
Filed: 1985-07-19
Abstract: A liquid/gas seal employs a dip pipe 15 with its lower end preferably notched (at 16) for passing gas into liquid contained in a tank 17. The flow gas displaces liquid from the tank 17 into a surrounding vessel 11 and the liquid can flow away via a weir plate 27. The tank 17 is closed except for one or more small bores 20 in its base wall 19 spaced from the dip pipe 15 which permit the liquid to return in the tank 17 to re- establish a normal level over the lower end of the dip pipe 15. Upstanding baffles 21 extend between the interior of the tank 17 and the dip pipe 15 and project above the normal liquid level to avoid undesirable movement in the body of liquid in the tank. <IMAGE>

Title: Optical frequency shifter for heterodyne measurement
Inventor: KOIKE OSAMU
IPC: G02F2/02
Filed: 1986-01-22
Abstract: In an optical frequency shifter for producing an output light beam 35' which has orthogonal p- and s- components having optical frequencies different from each other, a laser oscillator 11' generates a laser beam 12' including the p- and the s-components which have the same optical frequency and which are separated by a polarizing beam splitter 41 as first and second partial beams 42,43 respectively. The first and the second partial beams are acoustooptically shifted 17' in frequency relative to each other to produce first and second intermediate beams, with the p- and s-components kept unchanged. The first and second intermediate beams are combined by an additional beam splitter 52 into the output light beam. Specifically, only either one of the first and second intermediate beams may be subjected to the acoustooptic frequency shift, with the frequency of the other intermediate beam kept unchanged (as shown). Alternatively, both the first and second intermediate beams may be subjected to acoustooptic frequency shift. The arrangement forms a source of object and reference waves in a heterodyne system for measuring e.g. length. <IMAGE>

Title: Ultra-violet photo-ablative development of X-ray exposed photoresists
Inventor: ROSSER ROY JONATHAN
IPC: G03F7/36
Filed: 1987-01-22
Abstract: Ultra-violet photoablation can be used as a non-chemical means of developing patterns that have been exposed onto photoresist by x-ray or electron beam lithography. The latent image in the resist or polymer is developed by ultra-violet photoablation to remove the exposed or unexposed regions. The lithography or pattern exposure can be accomplished by any damage inducing (i.e. chemical bond breaking) radiation or particles of sufficient energy and intensity. The photoablative development can be carried out by any electromagnetic radiation source of sufficiently high energy and intensity.

Title: Pipe handling/lifting tool
Inventor: LIBBY JAMES HEBER
IPC: B25B5/14
Filed: 1987-11-24
Abstract: A pipe handling or lifting tool for operation by insertion into a pipe 1 comprises a former profiled at 4 to slidably conform to the inner surface of the pipe 1 with the upper part of the former having a progressively reducing cross-section area which creates an annular gap between the former and the pipe of progressively increasing width. A resilient element 16, 21 for releasably packing into the annular gap is provided and the upper end of the member has means 7, 13, for connection with a lifting rod or member 14. With the former inserted into a pipe and the resilient element packed into the annular gap over substantially the periphery of the former, lifting of the former causes increase of friction between former, resilient element and pipe enabling the pipe also to be raised. Removal of the weight of the pipe enables release of the resilient element, which may be assisted by pulling on a draw cord 27 threaded through a "necklace" of elements, which may be of rubber hose. <IMAGE>

Title: "Telecommunications network"
Inventor: MCCOMBE MICHAEL J
IPC: H04W16/14
Filed: 1990-07-20
Abstract: A cellular telephone network provides cells P1, P2, P3.. in the normal way, each cell having a predetermined total number of available radio channels. The network serves the subscribers of more than one subscriber system. For example, it serves both GSM and PCN subscribers. In order to prevent subscribers from one of the systems using all the available channels in any cell at any time, thus blocking out the other system completely, the base station controller in each cell limits to a respective predetermined maximum the number of channels which can be used at any time by the subscribers of each system. Thus, X channels can be allocated to GSM subscribers and Y channels to PCN subscribers. (X+Y) can be greater than N where N is the maximum number of channels available in each cell, though both X and Y are less than N. <IMAGE>

Patent GB-2256069-A (GB)
Title: Transaction processing.
Inventor: HASLER ANTHONY GERALD
IPC: G06F11/14
Filed: 1991-05-23
Abstract: A transaction processing system (for processing transactions involving several linked processors) has a master transaction manager (TM) controlling a number of resource managers (RMs) and associated resources, possibly through subordinate TMs. To ensure that consistency is maintained throughout the system, a 2-phase protocol is used, with Prepare and Commit states, so that all resources are updated to reflect the transaction (or the system reverts to its original state). This involves keeping log records at various processors. On a failure such as a processor crash, the failed processor recovers using records obtained from other processors. A TM 13 stores log records received from various subordinate RPs each record including a recovery field REG containing information about the RP organization. For recovery, the RP sends a request for log records and a mask field, and the TM 13 selects those records which match the enabled parts of the REC field. The RP can thus determine, depending on the nature of the failure, what records are required; eg for a particular recovery supervisor or a particular resource. <IMAGE>
