Title: Portable abrasive throwing wheel device
IPC: B24C5/06
Filed: 1982-01-06
Abstract: This relates to a portable abrasive throwing wheel device 20 which is utilized for blasting castings 248 and the like to effect the cleaning thereof. The portable device is of such a construction and is so suspended 108 wherein it has very little thrust reaction on an operator engageable positioning device 128 so that it may be readily manipulated. Further, the principal thrust of the device is carried by the suspension for the device and otherwise is directed towards the operator engageable positioning device so that is may be readily counteracted. The portable device includes a fixed motor 26 and a fixed abrasive supply 82 with a throwing wheel 54 carried by the motor and only a housing portion 43 being movable. The housing is rotatable about the axis of the motor and serves to permit the discharge opening of the device to be tilted to the desired angle for directing the abrasive blast where desired. <IMAGE>

Title: Thermal-radiation imaging devices and systems
Inventor: DYSON CLIVE MALCOLM
IPC: H01L31/0352
Filed: 1982-03-05
Abstract: A thermal-radiation imaging device comprises a substrate (2) e.g. of sapphire on which there are present semiconductor bodies or body portions in the form of parallel elongate strips (1), e.g. of cadmium mercury telluride. Biasing-electrode means (6 and 7) e.g. of gold are spaced along the strips (1) for causing a bias current predominantly of majority charge carriers to flow along each strip (1). The bias current supports an ambipolar drift of radiation-generated free minority carriers in the opposite direction. At the area of read-out means (8) in the drift path, each strip (1) is shaped to have a part (11 in Figure 2) which is narrower than the width of the strip (1) in front of said area and which provides a continuation of the drift path of reduced width and increased electric field. The increased electric field in the read-out area improves the device characteristics by increasing both the drift velocity and the responsivity of the device. The biasing-electrode means (6 or 7) may also provide the rear electrode of a pair (6,8 or 7,8) providing read-out means at the end of each strip (1), in which case the narrower part (11) extends from the front electrode (8) of the pair (6,8 or 7,8) to the corresponding biasing-electrode (6 or 7). <IMAGE>

Title: Optical perpendicularity measuring instrument
Inventor: SHUM LANSON YATSANG
IPC: G01B11/00
Filed: 1982-10-26
Abstract: An instrument for measuring the perpendicularity of deep holes with respect to the surface of a workpiece, contains a light source (14) at one end of a probe which shines light through an aperture (16) from where it is focussed by lens 24 onto a quadrature detector (26) at the opposite end of the probe. When the probe is inserted and centered in a hole, the deviation of the light beam from a zero point on the detector (26) is proportional to the deviation from perpendicularity of the hole. The detector can operate as a null sensing device when mounted on a movable table which is positioned by a servo feedback system. The position of the table is proportional to deviation from perpendicularity of the probe. The quadrature detector may comprise a square detector matrix, two linear matrices or a TV camera. <IMAGE>

IPC: C12H1/16
Filed: 1983-05-06
Abstract: Beverages such as whisky or beer containing nitrosamines including N-nitro-sodimethylamine (NDMA) are treated so as to reduce the NDMA content thereof by exposing the beverage to ultra-violet radiation having a wavelength such as to decompose the NDMA, preferably in the range 330 to 380nm, whilst preventing the beverage being exposed to radiation having wavelengths below 300 nm preferably by passing the radiation through a filter such as to cut out such wavelengths below 300 nm.

Title: Mode changer mechanism in power driven vibratory drills
Inventor: TASHIMO FUMIO
IPC: B25D16/00
Filed: 1983-08-23
Abstract: A power-driven vibratory drill operates selectively in a drill mode in which a drill chuck drive shaft 9 rotates without axial movement and a vibratory-drill mode in which the drive shaft 9 rotates and moves axially back and forth. For the drill mode, a changeover plate 11 slidably received in a holder 16 in a drill housing 2 is pushed in one direction to keep teeth 15 on a gear 8 fixed to the drive shaft 9 out of engagement with teeth 17 on the holder 16. For operating the drill in the vibratory-drill mode, the changeover plate is pushed in the opposite direction to bring the teeth 15 on the gear 8 into engagement with the teeth 17 on the holder 16. When the drill shaft rotates with a drill bit pressed against a work-piece, the drill shaft is forced to reciprocate axially through alternate engagement and disengagement between the teeth 15, 17. <IMAGE>

Title: Time of flight measurement for ink jet printers
Inventor: EVANS DAVID
IPC: B41J2/125
Filed: 1983-12-21
Abstract: Apparatus for giving an indication of the time of flight of the ink stream of an inket jet printer comprises detector means (16) towards which one or more selected droplets of the ink stream may be directed by a deflection system comprising charging electrode (5) and deflecting electrodes (8). The detector means detects the presence of the selected droplets to give an indication of the time of flight of the said droplets. The detector may be a conductive element on which a charge is induced by the impingement on approach of the droplets, a piezo-electric element or a photo-electric system. The time of flight may be calculated and displayed, or employed to control printing parameters such as ink supply pressure, deflecting charge or the rate at which items to be printed are conveyed past the printer. The time of flight also acts as a useful "state of health" monitor, to detect blockages or other malfunctions of the printer. <IMAGE>

Title: Guiding and arresting falling loads
Inventor: WILLIAMS GEOFFREY HUGH
IPC: B65G11/20
Filed: 1985-03-04
Abstract: The apparatus is for handling loads, such as barrels or kegs containing alcoholic beverages, from a first elevation to a second lower elevation. The apparatus comprises a guide which includes two spaced guide rails (12) for guiding the load during movement under the influence of gravity from the first to the second elevation and an arrestor (24) at the lower end of the guide rails for gradually arresting movement of the load. The arrestor comprises a load receiving device (26) which extends into the path of movement of the load and which is pivotable relative to the guide rails about a horizontal axis (36). Tension springs (32) urge the load receiving device towards its upper position against stops (46). An hydraulic damper (34) resists pivotable movement of the load receiving device between its upper and a lower position so that when a load, such as a barrel or keg, strikes the load receiving device the load receiving device moves from its upper towards its lower position resisted by the damper to gradually arrest movement of the load. <IMAGE>
