Title: Magnetic field double coil compensating device - has closely wound coils to obtain homogeneous radial intensity between polar pieces
Inventor: DOUBLE GLEN P
IPC: H01F5/00
Filed: 1976-08-10
Abstract: Homogenous radial intensity of magnetic fields is obtained by compensation for the change in intensity from the centre of the outside of the field produced by polar pieces, and can be used in nuclear magnetic resonance equipment. It has a winding (17) which is placed between the polar pieces of a magnetic field generator. The winding (17) has two coils (16,18). Each coil has one or several conductors, or it may be a printed circuit conductor. Each coil (16,18) has its length made-up of a conductor which is situated next to the similar conductor of the other coil, such that a common magnetic field is produced. The coils (16,18) are positioned with their length perpendicular to the axis of the polar pieces. The winding (16,18) is excited by an adjustable d.c. supply. The supply circuit has a variable potentiometer (24) and a battery (20).

Title: Centralised supervisory and alarm system for remote subscriber units - uses three signal transmission system to detect and verify correct alarm condition
IPC: G08B29/08
Filed: 1976-08-19
Abstract: The supervisory and alarm system controls from a central post a number of remote installations via signals transmitted over telephone wires. Interruption of a signal during a predetermined time period actuates an alaram. The time also transmits during this period a succession of irregular signals which are designed to counteract fraudulent recorded signal transmission. In the central supervisory unit there is a section for each subscriber on which is mounted a differential transformer. Through this transformer to the subscriber circuits are applied signals from the incoming line. The transformer also introduces into the circuits the succession of irregular signals emanating from a central source. The differential transformer ensures during processing of the output signals that the effect of irregular signals from the central source are minimised. The subscriber circuits in the central unit have an amplifier with automatic gain control amplifying the frequency of the irregular signals.
Patent FR-2323974-A1 (FR)
IPC: F28F3/08
Filed: 1976-09-02
Abstract: 1522369 Plate heat exchangers A PV V CO Ltd 23 Aug 1976 [10 Sept 1975] 37283/75 Heading F4S A heat exchanger comprises a pack of plates 17-23 apertured at corners, associated gaskets, and discs 1, 2, 3 and 13, 14, 15. Flow of two liquids through the heat exchanger is as indicated at A and B. Plates 17 and 23 have an aperture at each corner but, to guide the flows as indicated, some of the other plate corners are unapertured. The unapertured corners are reinforced by the discs, e.g. each disc being attached to one of its adjacent plates by welding. The spaces between plates 19-20 and 20-21 are unused for flow of liquid. As shown each of liquids A and B makes two passes through the heat exchanger. Considering flow of liquid A, the changeover between passes thereof is obtained by the group of four plates 18-21 which are generally similar to the other plates in the pack but have unapertured top left corners as viewed in Fig. 1 with the reinforcing discs 1-3 therebetween. The discs are isolated from the flows of the liquids, e.g. see Fig. 2. Similarly, for liquid B, changeover between two passes is obtained by the group of four plates 19-22 which have unapertured top right corners. The arrangement is such that for each of the groups of four plates 18-21 and 19-22 the central one of the three flow spaces defined therebetween is unused for flow of liquid. The plates of the pack may have crossing and abutting corrugations. Specifications 1,346,311 and 1,207,016 are referred to.

Title: Lathe or thread cutting machine bar stock feed - has retractable support with V=shaped cut=out in which bar resets
IPC: B23B13/08
Filed: 1976-09-02
Abstract: The retractable work-piece support is for use on lathes or thread-cutting machine and centres a bar as it is being fed longitudinally to the machine station. The support is used in conjunction with a tubular bar-guide (5) and takes up movement between the bar (W) and the guide (5) to reduce the noise caused by the workpiece rotating within the guide. The support may retract to permit the passage of the thrust-bar as it follows the workpiece bar (W) through the guide (5). The pad or bit (1) in contact with the bar (W) may be demountable. Several such supports may be used at longitudinal intervals along the guide (5). An adjustable jack-powered (3) slide (2) may support the bit (1) which enters a radial opening in the guide (5).

Title: Annular well blowout preventer - has disc extending sealingly through annular wall to transmit inward movement of annular piston to packerr
IPC: E21B33/06
Filed: 1976-09-06
Abstract: A resilient annular packer, is in an annular recess in the bore of the preventer housing and sealingly engages the upper end of the recess. A resilient annular piston is in a chamber which surrounds the recess and is separated therefrom by a wall. A disc extends sealingly through the wall to transmit inward movement of the piston to the packer to contact the latter into engagement about an object in the bore or upon itself when the bore is empty. There is provision for exposing the outer surface of the packer to the pressure in the bore. The preventer is relatively short and of small radial extent and is relatively inexpensive to mfr. and the pressure opposing closure of the preventer acts on a relatively small area.

Title: Control circuit for servomotor altering lamp intensity - produces pulse whose sign and duration determine direction and distance of movement of control potentiometer
IPC: H05B39/04
Filed: 1977-02-25
Abstract: The control circuit, for a servomotor altering the intensity of a lamp or light, produces an error signal by comparing the actual lamp intensity with an intensity reference. The error signal is converted into a pulse that triggers the component that starts and supplies the motor. The motor moves the slider of a potentiometer connected into the lamp circuit. The sign of the triggering pulse determines the direction of the motor's rotation and its amplitude the duration of that rotation.
