Title: Exercise device
Inventor: BAGGETT IAN
IPC: A63B23/12
Filed: 1989-03-31
Abstract: A hand held exercise device has a shaft 11 with one or more fixed handles 12, 13 and 14, together with a sleeve divided longitudinally into two parts incorporating a handle 16 which slides along the shaft. Resistance to movement along the shaft of the sleeve and handle varies according to how hard the handle is gripped due to friction between the sleeve of the handle and the shaft. Exercises are performed by gripping one of the fixed handles in one hand and the sliding handle in the other hand and either pushing the handles together or pulling them apart. <IMAGE>

Title: Liquid presence detector
Inventor: LEWIS ARTHUR LEONARD
IPC: G01M3/16
Filed: 1989-04-17
Abstract: The detector includes apparatus in the form of a pad 10 for use over a liquid detector 12 comprises an upper absorbent portion 14, 16 and spacer means 18 which space the upper portion 14, 16 from the detector 12.

Title: Data communication
Inventor: RICHARDS JOHN MURRAY
IPC: G06Q40/04
Filed: 1989-10-24
Abstract: A system for communicating output information 812, relating to a plurality of different type events, e.g. money market transactions, from one or more uniquely identifiable local data bases 814 at which the output information is initially collected, 816, to a remote back office data base is disclosed, in which data may be requested from a local data base in order of events independently of the type of events involved. Each of these types has an associated field list which uniquely defines the transmission format of the information although the request 800, 804, 806, for the information is by a unique "ticket" identifier which is independent of the type and comprises the unique identification of the local data base which is the associated terminal controller and the sequential number corresponding to the order of confirmation of an event at the particular local data base. The local data base also stores a status record which changes with each change in the number of confirmed events. By requesting this status record with automatic updates, the remote back office database can be advised that additional confirmed events have occurred and can request updates without the need for continual polling. …<IMAGE>…

Title: Method of inspecting pancake tape
Inventor: FUKUSHIMA MASAAKI
IPC: G11B27/36
Filed: 1990-12-19
Abstract: A method of inspecting a pancake tape during recording by a high speed duplicating apparatus in which information is recorded on the pancake tape, while at the same time the information recorded is reproduced for immediate inspection. A plurality of cassette tapes are defined consecutively on the pancake tape. The first cassette tape is inspected to detect a maximum peak level of the reproduced information which is stored as a reference signal. When each of the cassette tapes following the first cassette tape is recorded with the same information as the first cassette tape, the recorded information is simultaneously reproduced to detect a maximum peak level as a data signal. The data signal is immediately compared with the reference signal from the first cassette tape to detect which is greater in magnitude. If the data signal is smaller than the reference signal, the cassette tape is rejected as a defective tape and the recording apparatus is immediately stopped. The same procedure may be used to inspect successive segments of each cassette tape. <IMAGE>

Title: Drying semiconductor materials
Inventor: AIGO SEIICHIRO
IPC: H01L21/00
Filed: 1991-02-08
Abstract: In a spin-dryer having a rotor 11 on which semiconductor wafers to be dried are set, nitrogen gas is released at a low rate to enclose the rotor in a nitrogen gas atmosphere from the time that the semiconductor wafers are arranged on the rotor until the start of the spinning of the rotor, and then at a relatively high rate from the start of the spinning of the rotor or from immediately before the start of the spinning, in order to dry the semiconductor wafers without oxidation. The downward flow of air into the rotor is prevented for a preset time period from the start of the spinning of the rotor or from immediately before the start of the spinning. Air is then caused to flow into the rotor after an elapse of the preset time period by raising a lid 25 including a seal 27. The nitrogen gas may be heated by a heater 30 and may flow through a filter 21. <IMAGE>

Title: Recoverable tunnelling machine
Inventor: HERRENKNECHT MARTIN
IPC: E21D9/087
Filed: 1991-09-10
Abstract: A tunnelling machine for driving inaccessible tunnels by a pipe jacking system can be moved out again through the tunnel driven by it. For this purpose, an annular outer area (2b) is provided on the cutting hand (2), and one outer casing (4b, 6b) each is provided around the control head (4) and the machine tube (6). The outer area (2b) of the cutting hand is connected to its inner area (2a) and the control-head outer casing (4b) is connected to the control-head housing (4a) by connecting elements (24, 26). Specifically releasable restraining devices (28) hold the machine-tube outer casing (6b) on the machine-tube housing (6a). After the final depth is reached, the control head (4) can be moved back by means of the control devices (40) to such an extent towards the machine tube (6) that the connecting elements (24, 26) are broken. If the restraining devices (28) are then released, the tunnelling machine is separated from the extracting-tool outer area (2b) and the outer casings (4b, 6b) and can be withdrawn by withdrawal means (42) provided for this purpose. The invention enables the tunnelling machine, for reuse, to be recovered in a simple manner even from tunnels which do not end in a target shaft. <IMAGE>

IPC: F16K15/14
Abstract: 914,943. Valves. U.S. INDUSTRIES Inc. Jan. 25, 1960, No. 2708/60. Class 135. A check valve comprises a generally tubular core C of which the bore terminates at an aperture opening to the exterior of the core, a flexible sealing member or sleeve S having a portion externally engaging the core and another portion formed with abutting lips which open apart to permit outward flow through the said aperture, and a closure member supported in alignment with the aperture, this closure member moving away from the aperture during outward flow and moving against the core to cover the aperture when fluid pressure on the exterior of the sleeve exceeds that in the bore so as to prevent extrusion of the sealing member into the aperture.

Title: Road surveying
Inventor: DARLING BARRY ESMOND
IPC: G01C3/10
Filed: 1992-03-05
Abstract: Road surveying method comprising taking vertical angle measurements of points on the roadway spaced apart along a notional line extending transversely across the roadway. For illustration a single point (15) for measurement is shown. The measurements are taken by an angle measuring instrument (19) comprising a pair of vertically-spaced theodolites (20, 21). All measurements are taken with respect to a datum defined by a marker (11) positioned on the road surface. For a complete survey, a series of markers (11) are positioned at spaced-apart intervals along the roadway. The method has the advantage that personnel do not need to step onto the carriageway in order to carry out the survey, and the road does not therefore need to be closed or restricted. <IMAGE>

Title: Clamping device for thin panels
Inventor: LANDERS DAVID MAXWELL
IPC: B23K37/04
Filed: 1992-07-23
Abstract: A device which will clamp thin panels in close proximity abutment to each other has a thumb-grip 4, a bridge-piece 2, a toggle-bar 3 and a pin 1. The toggle-bar and the pin are able to pass through a narrow joint gap between those panels which are to be clamped. Rotation of the thumb grip 4 along ramps 5 raises the toggle-bar/pin assembly, whereupon the toggle-bar is trapped beneath the panels and the panels are clamped between the toggle-bar and the bridge-piece. The device requires access to one side only of the panelwork in order to fit manipulate and remove it, and may, for example, be used to support repair panels on double-skinned motor vehicle bodies in preparation for butt-weld jointing. <IMAGE>
