Title: Sample-holder for mass spectrometer
Inventor: TANAKA KAZUO
IPC: G01N1/28
Filed: 1987-11-20
Abstract: In a mass spectrometer which ionizes samples by bombarding the samples coated on a sample holder with a primary beam of neutral particles or ions, and analyses the secondary ions emanating from the sample surfaces, the sample-holder comprises a rotatable shaft 17 having a front end portion inserted in the ionization chamber of the mass spectrometer, a base 18 mounted at the front end of the shaft, and a pair of sample-holding sheets 19a, 19b on which samples 20a, 20b are coated, the holding sheets extending parallel to the axis of the shaft, and disposed 50 as to show a rotation symmetry with respect to the axis of the shaft. As shown the sheets 19a, 19b may be mounted about the base 18; alternatively, Fig. 5 (not shown), the base is modified to provide a notch therein in which the sample-holding sheets are located. Thus two different samples, or an unknown sample and a reference sample may be alternately examined by rotating the shaft through 180 DEG . <IMAGE>

IPC: G01K1/02
Filed: 1987-12-03
Abstract: A thermocouple arrangement comprises a base wire 1 and a plurality of junctions 3 spaced along said wire, each of said junctions being connected to a monitoring means which provides a visual indication of the temperature at each junction 3, e.g. on LED bar graph display for each junction. The base wire 1 may be placed in a PTFE tube. A heating coil 2 may be disposed along the length of the base wire 1 to assist in detection of liquid flow; flow transverse to the wire; indicated directly by the temperature measurements and for flow parallel to the wire a bubble is introduced and affects the output of the adjacent couple(s) (transit time measurement). The array of couples may also be used to indicate the output of an ultrasonic transducer, e.g. as used in hyperthermia treatment. Temperature gradients may also be assessed by the arrangement, including an assessment of time of death of a corpse. <IMAGE>

Title: Sample and hold circuit
Inventor: JOY ANDREW KEITH
IPC: G11C27/02
Filed: 1988-01-29
Abstract: A sample and hold circuit comprising a first diode ring (NOT SHOWN) having an input for an analog quantity to be sampled, a sampling capacitance coupled to the ring output, first and second current sources for providing current into and out of the ring, and switch means for regulating operation of the ring, wherein the first current source is constructed to provide a high output impedance which is substantially invariant over the expected range of operating frequencies, and a biassing arrangement is provided which fixes the current level of the first current source whilst permitting the bias of the second current source to vary in order that the second current source mirrors the current produced by the first current source. The bias arrangement uses a diode ring (40) of identical construction to the diode ring used to sample the input signal, the bias diode ring having a grounded input terminal (42) and being permanently turned ON to provide a reference voltage on its output terminal (6) which is used to determine the currents of the current sources sourcing and sinking current (i) to and from the sampling diode bridge. <IMAGE>

Title: Multi-colour printing involving thermography
Inventor: FOX HUGH
IPC: B41M5/34
Filed: 1988-08-02
Abstract: A method multi-coloured/thermographic printing comprises the steps of printing onto sheet material at least two colours, at least one of which is a rubber-based ink, and distributing a sufficient amount of a nylon-based dust onto the wet or tacky rubber-based ink(s) to ensure the presence of an excess amount of dust. The excess dust is then removed and the sheet material and the dust is heated to a temperature sufficient to melt the dust and cause the rubber-based ink image(s) to rise relative to the sheet material. The resulting product is then cooled. In one embodiment, cyan, yellow and magenta inks are quick-drying oil-based inks. With black as the rubber-based ink provided the raised effects.

Patent GB-2236744-A (GB)
Title: Container closures
Inventor: COX R MICHAEL GRAHAM CAREY
IPC: B65D47/24
Filed: 1989-09-29
Abstract: A closure for a container of flowable liquid has relatively moveable spout and body parts 10, 50. A depending tube 12 on the spout part fits into a bore on the body part and the spout part can be moved relative to the body part between a position in which the material can flow into the body part, into the tube and out through the spout and a position in which such flow is prevented. Direct movement of the spout along a path between these positions is prevented by engagement of a follower on one part with a guide surface on the other part which constrains the spout to be moved out of and back into said path before communication can be established. This makes the closure difficult to open for young children. Preferably the open and closed positions are spaced angularly but not axially. <IMAGE>

Title: Retaining tool holders in tool post
Inventor: BOWMAN HUGH PARKER
IPC: B23B29/04
Filed: 1990-03-19
Abstract: The post comprises a block (12) having a Morse tapered hole formed therein accepting a mating tool holder, the tapered hole allowing a tang (18) projecting through the block. The tang (18) is slotted and via the slot is engaged by a locking means (23) capable of pulling the tool into the hole (13). The locking means (23) is a disc with a cutout to accept initially the tang (18) and which is rotated to engage with a cut-out in the tang. Rotation causes axial disc movement, by a screw thread or helical disc form, to provide the tool pulling. <IMAGE>

Title: Battery powered childrens ride
Inventor: MARSTON MICHAEL GEORGE
IPC: A63G19/20
Filed: 1990-06-13
Abstract: A coin or push button operated ride(s) of the type that when placed on the floor or pavement will not move. However a toy, affixed to the none moving base, will be set in motion when a coin or push button switch operates the mechanism; so giving a child a ride. The sole source of power for the entire ride, including the motion of the toy, is derived from a special cyclic battery or batteries of a size equal or above the ride's requirements. This method of power produces an electrically safe ride(s) relative to mains electric powered ride(s). Being battery powered also allows for much greater versatility in location - not needing to be by a mains socket outlet when in use. <IMAGE>

Title: Retractable camera lens assembly
Inventor: BITTNER WILFRIED A A
IPC: G03B17/04
Filed: 1991-09-12
Abstract: A retractable lens system (20) for a camera (22) includes a stop for determining at least one operating position for the camera lens assembly. A spring (98) constantly urges the lens assembly against the stop. When a lens cover (42) is moved from the open to the closed position, the lens assembly (36) is moved against the force of the spring to a compact retracted position close to the shutter assembly (40). In a camera with adjustable focus, the shutter assembly is fixed relative to the camera film plane and the lens assembly is moved through a range of focus positions by a solenoid and lever arrangement that adjusts the position of the stop. The pivot point of the focus lever can be calibrated by a detent system for a specific lens back focal length. The retracted position is outside the range of focus positions. <IMAGE>
