Title: Rotary Gem Stone Support
IPC: B28D5/00
Filed: 1978-11-20
Abstract: The radial position of a gem stone 12 is adjusted using a special rotary support which is used when working the stone and has a body member 1, 2 for connection to a rotary mount and a stone holder 8. For adjusting, the stone holder 8 can be moved radially with respect to the body member 1, 2 whilst keeping the axes of the stone holder 8 and body member 1, 2 substantially parallel, and there is means 13, 14, 15 for applying to the stone holder 8 a frictional clamping force which is substantially less than that required to hold the stone 12 in position during working. After adjustment, the stone holder 8 is firmly fixed to the body member 1, 2 using fixing means 13, 16. <IMAGE>

Patent GB-2011691-A (GB)
Title: An alarm unit
IPC: G08B23/00
Filed: 1978-12-04
Abstract: An alarm sensing network comprises a plurality of normally-closed switches (1) connected in series between first and second terminals (B1 and B2) of an alarm unit and a plurality of normally-open switches (2) connected in parallel between the first terminal (B1) and a third terminal (B3) of the alarm unit. In the event of an abnormal condition (i.e. one of the normally- closed switches opening or one of the normally-open switches closing) a warning is raised e.g. by sending a loud-speaker (HP). An abnormal condition is sensed by a current flowing through one of two bridges of series- connected resistors (R17, R18 and R19 or R37, R38 and R39). In each case a current flow through the bridge turns on a transistor (T7 or T9) connected to turn on a transistor T8 which supplies power to an alarm sounding circuit including the loud-speaker (HP). The second and third terminals are connected to the rest of the unit via diodes (D6 and D7); A plurality of alarm units may have their corresponding first, second and third terminals interconnected so that they share a common sensing network. The arrangement is such that, even without the diodes, there is little danger of a false alarm at one unit due to a low battery at another unit. <IMAGE>

Patent GB-2036379-A (GB)
Title: Correction of Errors in Railway Track
IPC: E01B35/00
Filed: 1979-10-31
Abstract: A magnetic tape record 29 of the actual state of the track, obtained from a recording vehicle, is used to control a correcting machine. The tape is synchronized with the travel of the machine by a sensor on a wheel 26 controlling the tape drive 28. Head 35 reads off alignment at intervals and the averager 44 generates a desired track alignment condition. Comparator 45 compares alignment at a point B, derived from tape B' by head 36, with desired alignment and feeds error signal to control hydraulic ram 48 for lateral adjustment of track. The signal from averager 44 representing track curvature is combined with speed input 51 to generate desired cross level for comparison with signal from head 37. The resulting error signal then controls lifting ram 54 or 55. Processing of the original record to obtain desired track condition or to obtain a record of error signals may be carried out in advance to produce a tape for control of the correcting machine. <IMAGE>

Patent GB-2039919-A (GB)
Title: Method of manufacturing bonded products of cellulose or cellulose derivatives
IPC: B27N1/00
Filed: 1978-07-06
Abstract: In a method of manufacturing bonded products, comprised completely or partially of cellulose or a cellulose derivative, such as saw dust, wood chips, paper or vegetable fibres, a condensation resin between an aldehyde, preferably form aldehyde, and urea, melamine or aphenol type is used as an adhesive. The product is irradiated to at most 5 M rad with ionising radiation. Then the material will undergo a certain cross-linking. Residual quantities of uncured adhesive substances are reduced at the same time. The radiation dose is adjusted so that residual quantities of aldehyde in the material will be reduced. Preferably, also the residual quantity of formaldehyde in the material is reduced. By adding additives containing olefinic, acrylic or comparable groups the extent to which cross-linking takes place is increased.

Title: Method of and apparatus for magnetically adjusting the position of a satellite
Inventor: BRUDERLE ERNST
IPC: B64G1/28
Filed: 1983-04-18
Abstract: In order to provide for the magnetic adjustment of the position of satellites (1), which may be both spin- and three-axis-stabilised an external disturbing moment V is compensated for by a magnetic moment generator B controlled by and collaborating with the magnetic field of the earth. In order to keep errors during the compensation as small as possible there is fed to the magnetic moment generator B a signal which is the sum of a control signal S derived in a regulating circuit and of an estimated control signal U. The derived control signal S is determined by reason by a position error signal E with the aid of the earth's magnetic field detected by a magnetic sensor or else with the aid of a magnetic field model of the earth. The estimated control signal U is determined mathematically or experimentally in advance with reference to the data of the satellite's orbit, the structure of the satellite and the like. <IMAGE>

Abstract: An electromagnetic medical applicator for tissue-heating comprises a single resonant element (1) in contact with one surface of a layer of material (5) whose opposite surface faces the body of a patient (6). The material has a wave-impedance which approximately matches that of the human body and a dielectric constant not less than for a material having unity magnetic permeability which produces this match. In one form the element is a patch resonator (1) on a substrate (2) backed by a ground-plane (3) and overlaid by the layer (5); at least the substrate may include both dielectric and magnetic material in order to combine a desired resonator size-reduction and wave- impedance. In another form a needle- type applicator is coated with the layer of material. <IMAGE>
