IPC: B24D18/00
Filed: 1968-09-18
Abstract: 1,214,393. Abrasive articles. G. F. KEELERIC. 18 Sept., 1968 [18 Sept., 1967], No. 44328/68. Heading C4V. Abrasive articles are obtained by mixing abrasive particles such as diamond with filler particles which are thickest at their centre and have a smoother surface than that of the abrasive particles and spreading the mixed particles over a surface, applying a layer of bonding material to the thickness less than the smallest distance measured from the centre of the filler particles to the surface, moving the filler particles and applying a further layer of bonding material. If more than a single layer of particles is to be applied the surface of the object may, after removal of the filler particles, be provided with a new layer of mixed particles and a further layer of bonding material, followed by removal of the filler particles and this series of steps repeated until the desired layer of particles and bonding material has been built up. The bonded layer may be applied by electro-deposition and be of metal. The filler particles may be of spherical shape and may be of different colour from that of the abrasive particles.

Title: Automatically reversible drive unit for a screwcutting die head
IPC: B23G1/22
Filed: 1968-09-19
Abstract: 1,211,900. Automatically reversible drive units. GEORG. FISCHER A.G. 19 Sept., 1968 [22 Sept., 1967], No. 44549/68. Heading B3N. An automatically reversible drive unit for a screw-cutting die which is to be rotated in two directions and which has a displaceable part which is adapted to be axially movable comprises a rotatable housing 1 for the die head, two selectively engageable driving shafts 4 and (5), Fig. 3 (not shown) adapted to drive the housing via a gear-wheel 3 and control means which in a first position connect a drive from a motor 13 through a first driving shaft 4 by means of a clutch 8, 8a to the housing and after a specific displacement of the displaceable part disconnect driving shaft 4 and connect the drive through a second driving shaft (5) by means of a second clutch (9, 9a) to the housing and after the displaceable part returns to its initial position disconnect the second driving shaft. The control means comprises an eccentric lever 22 which when rotated moves pins 31 and 29 to the right. Pin 31 is connected to a fork 32, the movement causes the fork to engage the clutch 8, 8a and thus drive to the housing 1. The pin 31 is retained in this position by a spring loaded plunger (34), Fig. 2 (not shown), engaging in a recess 33. As the die head rotates the displaceable part moves a holding part 18 to the right causing a pin (20), Fig. 5 (not shown), to engage and lock pin 29 in position. Lever 22 can now be returned to its initial position. After a specific displacement of part 18 a pin (41) causes pin 34 to disengage itself from pin 31 whence spring 36 urges the pin to the left thus disengaging the clutch 8, 8a and thus the drive to the housing 1. Pin 42 and lever 43 are operated by pin 31 to move fork 44 which engages the clutch (9, 9a) whereby the direction of rotation of the drive to the housing is reversed. When part 18 is then returned to its initial position it disengages pin 20 from pin 29 which is spring urged to the left thus disengaging the clutch (9, 9a) and thus the drive to the housing. In case of incorrect manipulation of lever 22 a release knob (48) is provided which is adapted to disconnect pin 34 from pin 31 such that part 18 will be returned to its initial position. Specification 1,211,899 is referred to.

Title: Improvements in and relating to Apparatus comprising a Source of Cold or Heat and a Duct through which a Medium can Flow to Transfer Cold or Heat respectively from the Source to a Part Located Remotely therefrom
IPC: F25B9/00
Filed: 1966-10-06
Abstract: 1,165,756. Refrigerating; heating systems. PHILIPS' GLOEILAMPENFABRIEKEN N.V. 6 Oct., 1966 [9 Oct., 1965], No. 44702/66. Headings F4H and F4U. Cold or heat is transferred from a source to a remote place by a heat transfer medium flowing in a duct which is provided with a plurality of heat exchangers so arranged that the medium is alternately in heat exchange relationship with the source and with the place. As illustrated, a compressor 25 passes medium through a heat exchanger 27 and then through heat exchangers 15 and 16 which are in heat exchange relationship respectively with the freezer 8 of a cold-gas refrigerator and with the place 10 to be cooled. Medium from the last heat exchanger 16 passes through a heat exchanger 28, a Joule-Thomson valve 29 and a reservoir 30 to be returned to the compressor through the heat exchangers 28 and 27. Cold is withdrawn from the reservoir 30 by a coil 31. The place 10 to be cooled may be a thermal barrier around the Joule-Thomson system. In a modification, Fig. 4 (not shown), the compressor feeds in series two cold exchange circuits which draw their cold from different temperature freezers of a cold gas refrigerator. In another modification, Fig. 1 (not shown), the heat exchanger 28, valve 29 and reservoir 30 are omitted and medium from the last heat exchanger 16 is returned and the compressor is in heat exchange relationship with the compressed medium. In another embodiment, Fig. 2 (not shown), medium is fed to the cold exchange circuit from the cold space of a cold gas refrigerator and returns from the circuit to the cold space.

[Also in Division H4] In a magnetic printing assembly, the magnetic circuit of the recording styli 11 is completed by a base member 12 shaped as shown or comprising a flat sheet (Fig. 6, not shown) and arranged so that the recording ends 26 of the styli when inserted in apertures 16 are in substantially flush relationship with the under surface of the member, which is located adjacent a magnetizable surface 9, and are peripherally separated therefrom by a non-magnetic sleeve 29. In the embodiment shown there are seven styli each comprising a core 25 tapering to a recording end 26 upon which is mounted the non-magnetic sleeve 29. The sleeve may be copper plating or glass the magnetizing winding is arranged around both the core and taper. The part of. the magnetizable member 12 in which the recording ends fit is of reduced thickness. As shown the other end of each stylus may fit in further aperture 24 provided in the member 12 or may be welded to said member (Fig. 6, not shown).

Abstract: 1405706 Associated working of tape recorders with cinematograph apparatus ELMO CO Ltd 25 Sept 1973 [25 Sept 1972] 44862/73 Heading G5R In a system for synchronizing the starts of a cine film and a magnetic tape, the tape-drive motor is energized first but the drive to the tape is made effective only after a predetermined delay to allow the motor to reach its operating speed. As shown, operation of the start button 6 of a cine camera 1 starts the motor 19, Fig. 5, of a tape recorder 2 and causes the energization, after a delay determined by a circuit 20a, of a solenoid 21. This moves a lever (68), Figs. 7 and 8 (not shown), which withdraws a brake (63) from a cassetted tape (42) and allows a pinch roller (59) to press the tape against a rotating capstan (51c), simultaneously closing contacts 29 to send a start signal to the camera motor.

Filed: 1962-11-28
Abstract: 1,019,906. Testing circuit breakers. LICENTIA PATENT VERWALTUNGS-G.m.b.H. Nov. 28, 1962 [Nov. 30,1961], No. 44969/62. Heading G1U. In an arrangement for testing the interrupting capacity of high voltage power circuit breakers under distant short circuit conditions, a source G supplies high current to the breaker S under test, while a shunt circuit comprising a capacitor C2 is connected in parallel with the source. An oscillatory circuit L1C1 is arranged in the shunt circuit in series with the capacitor C2 and is so designed that it simulates the transmission line at whose distant end the short circuit exists. This arrangement is differentiated from the prior art in that the breaker test current does not pass through the inductance L1, so that a physically smaller inductance may be used, and external flashovers across L1 do not damage the installation, since the capacitor C2 blocks low frequency current. The oscillatory circuit L1C1 may be in the form of a series of inductor-capacitor sections (Fig. 1d not shown), and such an arrangement may be combined with synthetic circuit breaker testing arrangements known in the art (Fig. 1e not shown).
