Title: Electrical switch
Inventor: MYERS JOHN HOWARD
IPC: H01H31/30
Filed: 1964-10-13
Abstract: 1,078,915. High voltage switches. JAMES R. KEARNEY CORPORATION OF CANADA Ltd. Oct. 13, 1964, No. 41806/64. Heading H2B. [Also in Division F2] The contact blade 17 of a highvoltage isolator is moved by means of a linkage first about a horizontal axis 15 into the closed position and then about its own longitudinal axis to make contact with the fixed contacts (50, 51), (Figs. 2, 3, not shown). The linkage comprises rods 24, 25 of adjustable length joined by universal couplings to the blade 17 and a rotatable member 21 mounted upon a crank 19 which is rotatable, by means of an insulator column, on a shaft 18; the rotatable member 21 is joined by a crank 33 to a link 34 rigidly carrying a cam follower 36 engaging a slot 31, 32 in a member 30, rigid with a fixed part of the switch. In rotating crank 19 anticlockwise to close the switch slot 31 and follower 36 initially prevent rotation of member 21 so that blade 17 is simply pivoted about 15 until follower 36 enters the opening 32 whereupon further rotation of crank 19 rotates the member 21 and also the blade 17. A coiled spring (60), (Fig. 7, not shown), acts to counterbalance the weight of blade 17. The switch can be modified to engage blade 17 with fixed contacts in both positions by forming a second opening 32 at the other end of slot 31. In a second embodiment (Figs. 9-16, not shown), a geared drive is inserted between shaft 18 and the insulator column and the counterbalance is achieved by a leaf spring (72); the cam follower 36 is permitted to rotate and member 21 is prevented from rotating in the initial movement of crank 19 by means of a second cam and follower (85, 89). The linkage is arranged to pass over centre in its extreme position to prevent reverse movement of blade 17. Connection to blade 17 may be established by a second clip contact (not shown), engaging an extension of the lower end of blade 17. Connection to the fixed contacts (50, 51), (Fig. 9, not shown), is established through a voltage grading ring (79).

Title: Scanning device for axial transverse tomography
IPC: F16H21/20
Filed: 1975-10-14
Abstract: 1526234 Tomography COMPAGNIE GENERALE DE RADIOLOGIE 14 Oct 1975 [14 Oct 1974] 42088/75 Heading H4F [Also in Division F2] X-ray tomography is performed by a scanning device including at least one source S, Fig. 1, and at least one detector D caused to scan a vertical aperture O in which a patient may be placed upon a support T. The scanning motion comprises a sequence of rectilinear reciprocal translations of the source detector assembly with a rotation of the assembly about the axis of aperture O after each translation. The scanning motion is derived by a drive coupling which enables continuous non- interrupted operation of driving motors. The reciprocating scan component is derived at a slide 70, Fig. 5, carried on a connecting rod 27 which is fixed at each end to radial pivot 26 of a pair of discs 20, 21 driven by shafts 30, 31 carried on an annular movable support plate 63 which rotates intermittently (in the reversal period of the reciprocating scan component) about the aperture axis 61. A motor 11 drives shafts 30, 31 simultaneously via a reduction gear and chain link 12, 65. Motor 11 also drives support plate 63 in intermittent rotation by a "Maltese cross" type continuous in-intermittent out coupling 50 described in more detail w.r.t. Fig. 6 (not shown). The pitch of the reciprocal scan component may be varied by a motor 40 which alters the radial displacement of pivots 26 on discs 20, 21 by equal amounts. The mechanism for performing this variation is described w.r.t. Fig. 3 (not shown). Control signals indicating commencement and termination of reciprocation, extent of reciprocation completed, sampling intervals etc. are derived from a mechanism similar to that providing the reciprocal scan component but of fixed pitch in conjunction with photo-electric sensors and signal generators, Fig. 4 (not shown).

IPC: G03G15/05
Filed: 1968-09-05
Abstract: 1,245,773. Delivering sheets. EASTMAN KODAK CO. 5 Sept., 1968 [6 Sept., 1967], No. 42327/68. Heading B8R. [Also in Divisions G2-G3] An electrostatic printer has a flexible photoconductive member 18 supported at either end on supporting means having pairs of upstanding arms 25, 26 and 45, 46 which are movable toward and away from a planar platen 14 upon which a receiving sheet is positioned, the supporting means being moved toward the platen so that initially a line contact is made between the photo-conductive member and the receiving sheet followed by progressive, co-extensive contact. A potential is applied between the conductive platen and a transparent conductive layer provided on the photo-conductive member to produce an electrostatic force, and the receiving sheet is clamped to the platen prior to stripping the photo-conductor member from the receiving sheet after exposure to an actinic radiation pattern. In operation, a length of receiving sheet is fed on to the platen from a storage roll, and motor 40 switch on to initially rotate cams 29, 30 which co-operate with U- shaped cam followers 27, 28 to lower crossmember 24 upon which one end of the photoconductive sheet is mounted. At the same time a cutting blade 36 moves down and co-operates with a cutting bar 35 fixed to one end of the platen and cuts through the receiving sheet. When the one end of the photo-conductive element has been lowered, the other end attached to cross-bar 44 is lowered, a cam follower 54 co-operating with a cam 55 being also rotated by motor 40. The cross-bar 40 is pivotally mounted on links 47, 48, and the photo-conductive sheet is maintained under tension by springs 52, 53. A further cam 79 and cam follower 78 operates a clamping device C through members 69-75 to clamp the receiving sheet to the platen. After exposure, the photoconductive element is raised, the clamping device released, and the receiver sheet moved to a developing station.

Title: Improvements in or relating to transmitting apparatus
IPC: H04J1/14
Filed: 1960-12-21
Abstract: 935,855. Carrier transmission. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 21, 1960 [Dec. 24, 1959], No. 43900/60. Class 40 (4). In a transmitter for use in a carrier telephone system, supervisory signals (including ringing &c.) are transmitted in a portion of the allocated channel by applying the speech carrier and a signal frequency (outside the speech band) as input signals to a transistor which can be made conducting or non-conducting by means of a signalling switch and bias voltage connected to one of its electrodes. Speech from microphone 5 is modulated at 7 on to a 20 kc/s. carrier from generator 8 and is applied via low-pass 9 (<23.4 kc/s.) and highpass 3 (>20.3 kc/s.) filters to line 4. A signal frequency of 3.825 kc/s. is mixed with the 20 kc/s. carrier in transistor 11 and applied as a 23.825 kc/s. signal to line 4, signalling carrier suppression or retention being determined by the position of switch 35 in the collector circuit. In one system of signalling described, transistor 11 is normally conducting but on the operation of signalling switch 21, the base potential of transistor 11 rises and consequently conduction ceases, an impedance network 24, 25, 26 being included in the base circuit so that the "switch on " and "switch off"  times of the transistor are slow in order to suppress unwanted harmonics and consequent distortion and cross-channel interference. The operation of switches 29, 30 provides a system in which the supervisory signal is normally interrupted and is only transmitted on the operation of switch 21.
