Abstract: 786,503. Lamps. CARR FASTENER CO., Ltd. Oct. 27, 1955 [Dec. 1, 1954], No. 34862/54. Class 75(4) A translucent or transparent synthetic plastic cover 1 for a lamp comprises a resilient hollow shank 5 integrally 'extending from one face of a lens portion 4 and having adjacent the end remote from the lens a peripheral outwardly extending ridge 6 which tapers inwardly towards the remote end, the shank being adapted to make snap-fastening engagement in an aperture in a support such as a panel 3 or a lampholder. The remote end of the shank has axial slots 10 dividing the shank into fingers 11; or the slots 10 may terminate short of the end of the shank. The diameter of the shank is equal to or slightly greater than that of the aperture. When the shank is pushed through the aperture from the front of the panel the fingers 11 are deformed until the ridge 6 clears the aperture. The fingers then spring outwardly and the panel is gripped between the rear peripheral surface 9 of the lens and the ridge 5. A key portion 12 on the shank co-operates with a radial groove 13 in the edge of the aperture. The lens may have a metal surround. A lampholder with which the cover engages comprises a tubular body having a forward neck of reduced diameter having a length equal to the length of the shank between the ridge 6 and the lens.

Title: Mechanical moving structure for an x-ray apparatus
IPC: A61B6/02
Filed: 1972-07-26
Abstract: 1393695 Gearing PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 July 1972 [29 July 1971] 34942/72 Heading F2Q A device, for moving an X-ray apparatus along a selected path, comprises a shaft 1, to which the apparatus is connected on a crank rotatable about an axis C, which axis is positioned eccentrically in a body 11, itself rotatable about a shaft having an axis B, which axis is in turn eccentric to an axis A about which a drum 3 can rotate, which drum carries the body 11 as shown. The crank is rotatable about axis C by a gear 20 which meshes with a gear 28 on a shaft rotatable about axis B through a gear 24 in mesh with a gear 25 in turn meshing with a gear 23 on a hollow shaft 15, which is rotatable about axis A and also carries a gear 22. The body 11 is rotated by a gear 18 carried thereon which gear is, through a gear 19, rotated by a gear 17 on a shaft 14 rotatable about axis A and also carrying a gear 16. The drum 3 is rotated by a toothed belt 6 which is driven by a pulley 7 rotated by a worm gear 9 itself driven by an electric motor 2 through a pulley 33. The shafts 15 and 14 are driven through gears 22 and 26 and 16 and 20 respectively, each of which is driven by a worm drive (not shown) from a shaft 32 or 31, respectively. Each of shafts 31 and 32 is driven by pulleys from the motor 2. Each pulley is connected to its respective shaft through an electromagnetic clutch, 39, 40 or 41 . By selective clutching of the pulleys and by suitably chosen gear ratios, the movement of member 1, the resultant movement due to the rotations of the various shafts about the axes A, B and C, can follow a straight line path,- a circular path, epicyclic path or other, more complex path (e.g. hypocycloid). To increase this selection of movements possible the shaft 32, which drives shaft 15, can be driven through either a pulley 37 or 38 so that its speed relative to that of shaft 31 and drum 3 may be altered from the normal (when the shafts 14 and 15 and the drum 3 rotate at the same rate).

Abstract: 1395375 Substation equipment PIONEER ELECTRONIC CORP 28 July 1972 [29 July 1971] 35528/72 Heading H4K In an automatic telephone answering machine having separate media for carrying an answer message and for recording an incoming message, both media are arranged to be operative simultaneously in response to an incoming call so that a caller who knows the ropes may start recording immediately and thus save his time. The recording circuit is provided with a phaseinverting stage whose output is effective to cancel the answer message, particularly when this is mixed with an incoming message, prior to recording. In operation, circuit 12 recognizes ringing current by operating relay Y1 whereby a motor M is energized in order to drive answer tape loop T1 and message tape T2. The output from T1 is impressed on the line 11 but is virtually suppressed from any signal to be recorded on T2 by means of phase shifter 15 and a variable attenuator 16. At the end of the answer message, metal strip 18 closes contacts 17 so as to bring up relay Y2 which is effective to declutch tape T1 from the motor. The circuit may restore either when the caller's message terminates or after a time interval determined by the circuit 12. Replay of the recorded messages via amplifier 19 and loud-speaker 20 is effected by closure of switch SW1 which brings up relay Y3 so as to effect the necessary circuit changes.
