Title: Measuring sheets of metal
Inventor: COLLINS BRYAN
IPC: G01B7/02
Filed: 1983-05-10
Abstract: Sheet metal measuring apparatus consists of a fixed flat platen (1) on which a metal sheet whose dimensions are to be measured, is placed. A first raised abutment (2) extends along the front edge (3) of the platen (1) and a second raised abutment extends along one side edge of the platen (1) and normal to the abutment (2). An accurately machined track (5) extends beneath the front edge (3) of platen (1) and has a longitudinal groove (6) to allow a transducer (7), e.g. differential transformers interacting with a scale on tube 20, to slide along the track (5). In operation, the metal sheet to be measured is placed on the platen (1) with one edge adjacent the front abutment (2) and a second edge against the abutment (4). The transducer (7) is slidden along the track (5) until the head of the transducer (7) abuts the edge of the metal sheet remote from the edge in contact with the second abutment and a probe on the transducer indicates visually the distance between the edge of the metal sheet adjacent the second abutment (4) and the opposite edge. <IMAGE>

Title: Non-destructive ultrasonic testing
Inventor: OPARA DR ULRICH
IPC: G01S7/529
Filed: 1983-07-18
Abstract: Echoes received from a test head are amplified by means of an amplifier, the gain factor of which depends upon a depth compensation signal which allows for attenuation of the ultrasound at any time. Synchronization of the individual units of the apparatus is effected by the first echo signal reflected by the surface of the test piece. In order to allow for the influence of the coupling liquid on the sonic field distribution in the test piece, a depth compensation signal A(t) is fed to the controllable amplifier after reception of the first surface echo. The starting value A(to) of the depth compensation signal is equal to the value T(to) of a depth compensation function T(t) derived at the time when the surface echo occurs, the depth compensation function T(t) starting with the transmission pulse (13) and allowing for attenuation of the ultrasound in the coupling liquid. <IMAGE>

Title: Coin testing apparatus
Inventor: JOHNSON PETER REGINALD
IPC: G07D5/00
Filed: 1983-07-28
Abstract: @ A coin testing apparatus subjects a coin inserted into a coin entry (1) and rolling down an inclined track (2) to testing at a testing station (3) comprising sensors (4,5,6) which may for example be inductive sensors. If a coin is found to be acceptable an accept signal is generated and this causes gate mechanism (8) to open to permit the coin to access accept path (9), the gate mechanism (8) being normally closed so that unacceptable coins can only access a reject path (10). A post-gate detector (11) in the accept path (9) senses the passage of an accepted coin and serves to close the gate mechanism (8) and also to determine allocation of a customer credit. A pre-gate detector (12) upstream of the gate mechanism (8) has its output logically processed with the accept signal produced when an acceptable coin is tested and/or with the output of the post-gate detector (11).

Patent GB-847278-A (GB)
Abstract: 847,278. Gyroscopic apparatus. KEARFOTT CO. Inc. Oct. 23, 1957 [Nov. 5, 1956], No. 33075/57. Class 97(3) [Also in Group XXXV] In a gyroscope, especially a rate gyro, the rotor casing is enclosed in a drum floated in a fluid in a housing and one of the end walls of the drum which carry trunnions journalled in hubbed bearings on the end walls of the housing also carries an element of a torque motor, the other element of which is carried on the hub of the adjacent bearing so as to enable the gyro to be moved for preliminary testing and to impart compensating torques during operation. As shown in Fig. 4, the gyro rotor 31 has a hollow shaft 33 rotating in axially pre-stressed bearings 34, 35. The rotor carries two sets of rings 36, 37 forming with fixed stator windings 38, 39 the driving motors of the rotor. The shaft 33 is mounted on a tension strut 45 with threaded ends which support the bearing stressing means, and two bearing supporting cylinders 41. 42 which are closed by threaded discs 76, 77. Side walls 61, 62 of the rotor casing are soldered to the cylinders 41. 42 and to a ring 70. To support the casing 11 in the drum 13, plugs 81, 82 are brazed into diametrically opposite openings in ring 70 and extensions of pads 96, 109 (Fig. 5). The casing is evacuated through a tube 85 which is afterwards sealed. The drum 13 is evacuated or filled with an inert heat transfer gas by means of a plug screw 129 and tube 95, which is sealed off. The drum is mounted in an external fluid containing housing by means of trunnions 98 (Figs 5, 7) and 114 (Figs. 5, 8) journalled in jewelled bearings 166 (Fig. 7) and 221 (Fig. 8) respectively. The bearings are mounted in hubs 165 and 214 respectively. The temperature is controlled by heating elements (Figs. 1 and 9, not shown) and the volume changes of the fluid are taken up by bellows 19 (Fig. 8). The rotation of drum 13 is limited by stop pins 121, 122 and balance about axis 92 is achieved by adjusting threaded screw weights 127. The stator of the torque motor (Fig. 8) is mounted on hub 214 and includes coils 202 and 203 which are wrapped round cylindrical shell 201 and cemented in recess 204. The coils are energised with direct current to turn permanent bar magnet 117 and cylindrical keeper 118 together with drum 13 to a reference position. Departure from the reference position is signalled by an inductive pick-off (Fig. 7, 10) having a stator 104 mounted on the end wall 140 of the housing. The rotor 103 consists of high permeability laminations and in the reference position each pair of rotor vanes 103A bridge two pairs of stator teeth (Fig. 10). The primaries 195, 194 and 196 are arranged so that, in the reference position, their inductive effects on the secondaries 202, 203 cancel out and adjacent primaries are oppositely wound so that the adjacent teeth embraced by each secondary are instantaneously oppositely magnetised. Adjacent secondaries are oppositely wound so that the induced voltages (which are only produced when the rotor 103 is out of position) are additive.
