Title: Improvement in universal joints
IPC: F16D3/46
Filed: 1941-01-06
Abstract: 545,022. Universe joints. HARRIS, C. W. Jan. 6, 1941, No. 170. [Class 80 (ii)] The intermediate member D which has grooves L, M, Fig. 5, therein at right-angles to one another, consists of a block which is produced by turning, e.g. a bar of steel about one axis F, G and then about a second axis H, K at right-angles thereto. The grooves are recessed at the bottom to receive beads O, Fig. 1, on tongues N of the driving and driven members C, E and these grooves and beads serve to hold the parts against axial separation. To enable the joint to be assembled, the grooves are cut away over an extent of about 120 degrees as at P, Fig. 1, 2, and the bead or lip O is made of a width, as shown at R, Fig. 1, that will permit it to enter the opening produced. Thus, the lip or bead is pushed into the cut-away part of the groove and then, with the block stationary, the driving and driven members are rotated through 180 degrees. The tongues are bevelled at S, T to avoid interference. Lubricant may be fed through holes W. In a modification a double joint is shown in Fig. 10, and this comprises 'two intermediate blocks connected by an extra centre piece V.

Title: Capsule rectification and conveying apparatus
IPC: B65G65/42
Filed: 1975-01-06
Abstract: 1494123 Endless conveyers feeding capsules ELI LILLY & CO 6 Jan 1975 [7 Jan 1974] 409/75 Heading B8A Capsules 5 fed from a hopper 24 in carriers 34 of a chain conveyer 30 are held slightly above parallel ledges 48, 48, of the carriers 34, by the action of a cam rail 56 extending parallel with the path of the conveyer. The width apart of the ledges 48, 48 is greater than the diameter of the body part of the capsule, but less than the diameter of the cap of the capsule. The cam rail ceases at a terminal portion 100 to permit the body part of body-first capsules to pivot downwardly. A further section 108 of the cam rail 56 then engages the downward pointing body portion and the capsule is turned into a cap-first altitude. The action is assisted by vacuum applied through a port 94 from a manifold 92. There is a secondary vacuum manifold 105 serving the space beneath the cam rail section 108. The carriers 34 then pass around a double chain sprocket assembly having radial arms 144 (Figs. 11, 12) corresponding to each carrier. Each arm has a cam follower 148 bearing on a fixed annular cam track 171, and a vacuum passage 146, having a bleed hole 158. The passage 146 transmits vacuum from the interior 164 of the sprocket shaft 126, to seats for attracting and retaining a respective capsule, relative to a shaped outer end portion of the arm 144. By the action of the cam track 171, the arm 144 is projected when it reaches a delivery station 170, and the vacuum is destroyed by the bleed hole 158 becoming vented to atmosphere in this raised position of the arm 144. The hopper 24 has a vibrating agitating plate 70, actuated by an air cylinder 74, energized by pulses produced by a valve 78 operated by a cam 82. The feed of the capsules is also controlled by pivoted fingers 84.

Title: Improvements in or relating to short-wave therapy apparatus
IPC: H05B6/50
Filed: 1952-01-07
Abstract: 710,669. Automatic frequency control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 7, 1952 [Jan. 9, 1951], No. 470/52. Class 38(4) The treatment circuit of a short-wave medical apparatus is kept in resonance with the oscillations of a frequencystabilized 'source by comparing the phase of the voltages in the source and the treatment circuits, and deriving therefrom a control voltage for corrective adjustment of a tuning impedance in the treatment circuit. As shown in the diagram, the tuned circuit 8 of the h.f. source is inductively coupled to the treatment circuit 21, 22. A phase-comparing valve 1 which may be of the nonode type has one control grid 5 energized by a coil 7 coupled to the circuit 8, and the other control grid 6 coupled by a coil 11 in the treatment circuit. When the treatment circuit is in tune the two grids are excited in quadraturo relation. and departure from this relation increases or decreases the relative phase angle, and correspondingly affects the anode current through the resistor 3. A second phasecomparing valve 2 has its grids 5, 6 excited in constant quadrature relation, one directly by the coil 7 and the other by a tune circuit 9. 10 connected to the coil 7 by a condenser 23. The anode current through the resistor 4 thus balances the current through resistor 3 when the treatment circuit is in tune. Departure from correct tune creates a difference of voltage between the anode points 12, 13 and causes the anode current of one of the valves 15, 17 to predominate. A motor 20 is thus started up in one or other direction, according to which the opposed field-coils 18, 19 carries the greater current. The motor 20 adjusts a tuning-condenser 21 or other element of the treatment circuit to bring it to resonance. Alternatively the anode currents of the valves 15, 17 may operate a polarized relay by means of which a device for adusting the condenser 21 is controlled. The treating element may comprise capacitor electrodes or a coil.

Title: Improvements in or relating to ikonoscopes, television cathode ray tubes and the like
IPC: H01J29/80
Filed: 1937-01-08
Abstract: 493,543. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE. Jan. 8, 1937, No. 624. Convention date, Jan. 11, 1936. [Class 39 (i)] In a cathode-ray tube containing screening or accelerating electrodes made of wire net, thin electrodes are prevented from casting an objectionable shadow on the screen either by placing them at the place where the ray has the greatest practicable breadth, i.e. as close to the electron lens as the deflecting electrodes will permit, or by so choosing their potential and by making them of such material that the secondary electrons emitted just compensate for the electrons absorbed. The Figure shows the invention applied to a tube in which a mosaic screen 5, on which an optical image is projected as described in Specification 489,362, is scanned by a cathode-ray, an aperture in a diaphragm 2 being focused on the screen 5 by means of an electron lens formed of the tube 3 and diaphragm 4. Arranged as close as possible to the deflecting plates 8, 9, is a wire net electrode 6a, the potential of which with respect to the electrode 4 can be adjusted. This electrode may, in addition to acting as a screen electrode, serve to collect secondary electrons emitted from the screen 5. An accelerating electrode 6b at a positive potential of 8000 volts relative to the screen 6a may also be provided. Alternatively a net 6c may be arranged near the screen 5 and made of such material, e.g. tungsten, that the secondary emission from it compensates for the electrons absorbing by it. In a modification the net is arranged across the end of a cylinder.

IPC: G11B5/58
Filed: 1991-10-24
Abstract: In a helical scan video recorder in which the magnetic heads are arranged on bimorph piezoelectric actuators it may be desirable, in order to counteract depolarization of the piezo-electric elements, to bias these elements. This is possible without the use of additional slip rings if the electrode to which the drive voltage is applied is connected, via a diode, to the electrode to which the bias is applied and the bias is applied, alternately with the drive voltage, at instants at which the associated magnetic head is not used. If the (lower) drive voltage is applied the diode is cut off and the bias is isolated from the drive.
