Abstract: 1,212,504. Inductive signalling; transponders. EURONICS Ltd. 29 March, 1968 [30 Dec., 1966], No. 58271/66. Headings H4L and H4U. A system for detecting the unauthorized removal of articles through an exit, comprises a transmitter generating an inductive field across or adjacent to the exit and a plurality of miniaturized oscillators, one oscillator being attached to each article. As described, the oscillators are energized by rectification of the signal from the transmitter and retransmit a signal on a different frequency from that received to one or more receivers coupled to an alarm system. The oscillators themselves may include an audible alarm. One transistor oscillator described includes an energizing circuit tuned to one frequency and retransmits on a different frequency, the incoming signal being rectified by a diode. In a further embodiment, the oscillator consists of a resonant circuit comprising an inductor, a capacitor and a diode in series, the diode generating harmonics, one of which is utilized as the alarm signal. The oscillator may be included in a price tag label.

IPC: B21J9/08
Filed: 1967-12-27
Abstract: 1,185,530. Upsetting tubes. GESELLSCHAFT FUR FERTIGUNGSTECHNIK UND MASCHINENBAU G.m.b.H. 27 Dec., 1967 [26 Jan., 1967], No. 58753/67. Heading B3H. The wall of a tube 1 is locally increased in thickness by exerting a constant upsetting force on one end of the tube, while limiting the radial spread of the tube wall either by rollers or by a mandrel. The upsetting force is provided by a punch 15, while the tube is rotated by a chuck 9. An induction heater 19 partly surrounds the tube, and is mounted in an hydraulically transversed carriage 16 which also houses the rollers 20 and 21. To impart a desired profile to the tube, templates 28 and 35 are provided, the templates being coupled for movement with the carriage 16. The outputs from transducers 30 and 31 associated with the templates indicate the desired and actual positions, respectively, of the punch 15, and are fed to a unit 34 for controlling the admission of fluid to the punch. When the rollers 20, 21 are used to limit the outward spread of the tube, signals from a transducer 37, associated with the template 35, and from a transducer indicating the position of the roller 21, are fed to a unit 40 which controls the roller position.

Abstract: 636,255. Electromagnetic ammeters and voltmeters. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 21, 1946, No. 34549. Convention date, May 31, 1943. [Class 37] In a moving-coil instrument wherein a single moving coil is unsymmetrically mounted, Fig. 1, the polepieces 1, 2 are symmetrical about a plane 3 which passes through them and the axis of rotation of the coil 6 is outside the plane 3, for example as at 5, coincident with one side of the coil. The field track of the coil is from zero deflection at 7 through the maximum torque position at 8 to maximum deflection at 9. The rate of change of field strength between 7 and 8 is different from that between 8 and 9 and as shown the coil is nearer to 8 at zero deflection than it is at maximum deflection. In modifications, Figs. 3 and 4 (not shown), the coil possesses an iron core which may be part of one polepiece and the axis of rotation is coincident with the coil side as in Fig. 1 but differently located in each case outside the plane 3. The axis of rotation 5 may be positioned between the coil sides 10, 11, as shown in Fig. 2. The invention is not restricted to permanent magnets. The Specification relates the invention to meters with non-linear scales wherein the axis of rotation has been so located as to ensure that the variation of field along the track of the coil side satisfies the prescribed mathematical law. Specifications 626,134 and 636,121 are referred to.

Title: Partitionable record pack
IPC: G11B23/033
Filed: 1978-11-28
Abstract: A pack of flexible magnetic recording disks may be partitioned "end- wise". In one embodiment the disks are hole-encoded and either cut in different hole patterns, or else cut in a common hole pattern and stacked to dispose each in a unique rotational "misregistration" relative to all others - the result being to generate sets of "partition bores" permitting associated automatic apparatus to selectively partition the pack and expose any desired disk-side for operation thereon. In another embodiment the disks are stacked between apertured spacers about a hollow spindle, the spacers and disks being partition-apertured and stacked to generate a set of partition bores. These bores cooperate with selectably rotatable gas jet means co- rotated on the spindle and adjustably rotated relative to the pack to register with a selected one of these bores. <IMAGE>

Title: Snap-fastener element
IPC: A44B17/00
Filed: 1979-06-01
Abstract: The invention concerns snap fasteners and a method of manufacturing a component thereof consisting of a plastics material head (2a) and a metallic eyelet (3a). The head (2a) has a recess (5a) formed in the under surface into which a flange (12a) of the eyelet is force fitted by pressing to flatten the flange. In use, the shank (11a) of the eyelet (3a) is staked to rivet a socket component (10) of the fastener to the front piece of fabric (20) in the usual way and an eyelet (3b) is similarly used to rivet the male fastener component to the rear piece of fabric to be fastened, again in the usual way. Instead of the eyelet (3a) a known form of pronged eyelet can be fixed to the head (2a). The advantages claimed are ease of manufacture and the fact that with the improved method of attaching the plastics head and the metal eyelet together, a longer life of the resulting snap fastener is obtained. <IMAGE>

Filed: 1979-12-05
Abstract: The regulating rod (10) for angularly displacing the pump pistons (13) of an in-line injection pump, for internal combustion engines for the purpose of varying the fuel delivery quantity, has a first group of sleeve- like shaped regulating members (17) rigidly connected to a carrier rod (19), and a second group of regulating members (18) each displaceable on the carrier rod (19), the regulating members 18 being interconnected by an actuating rod (21), to enable one group (28, 28 ...) of pump pistons to be rendered inoperative. In order to secure the actuating rod (21) against deflection, the entire length of the actuating rod is guided within a longitudinal groove (38) incorporated in the carrier rod (19), the latter passing through all the sleeve-like regulating members (17, 18, 24). Upon longitudinal displacement of the actuating rod (21) during idling and part load operation, only those pump pistons (28, 28...) which are actuated by the second group of regulating members (18) are moved into their stop position, and the other pump pistons (27, 27...) maintain their operating positions, whereby associated engine cylinders are loaded to a greater extent and operate more economically. <IMAGE>

Title: Process for the recovery of argon
IPC: F25J3/02
Filed: 1980-07-02
Abstract: Argon is recovered from a tail gas stream (37) remaining after recovery of hydrogen values from ammonia synthesis purge gas. In a first step, tail gas is cooled, preferably in a first heat exchanger (15) then a refluxing exchanger (17) to separate a condensate containing methane, argon and some nitrogen and uncondensed gas containing substantially all residual hydrogen and some nitrogen. The condensate, after expansion, is fed into a first distillation column (11) where methane is condensed, the overhead nitrogen and argon product being fed to a second column (13) where argon product (53) is condensed. The cold requirements of the process and heat for reboil and cooling for reflux for the columns are provided by an open cycle supplied with gaseous nitrogen from the second column as heat transfer fluid. Cooling for the refluxing exchanger is provided by an evaporating coolant comprising transfer fluid combined with the uncondensed nitrogen- hydrogen gas after expansion thereof. <IMAGE>
