Abstract: 813,106. Velocity modulated tubes. VARIAN ASSOCIATES. Aug. 10, 1955, No. 33623/57. Divided out of 813,103. Class 39(1). In a velocity modulation tube the collector electrode 3, Fig. 3 is a metal block 38 having formed therein an electron receiving cavity 40 comprising a cylindrical beam entry portion 39, merging into a portion which flares inwardly in a smooth concave curve and terminates substantially in a point. The concave contour is such that equal areas receive equal numbers of electrons, so as to avoid formation of " hot spots " during operation, a suitable mathematical shape being discussed. The collector has a double helical passage 41, 42 for water circulation, each helical passage communicating with the other only at one end. The collector is given a higher voltage than the resonator to repel the positive ions to the resonator so as to prevent positive ion bombardment of the collector. The tube is preferably of the "floating kidney type" other aspects of which are described and claimed in Specifications 813,104 and 813,105.

Title: Improvements in or relating to electrostatic dust collectors
IPC: B03C3/12
Filed: 1955-11-25
Abstract: 792,068. Electrostatic separators. FEIFEL. E., and PROCHAZKA, R. Nov. 25, 1955 [Dec. 10, 1954], No. 33900/55. Class 117 Apparatus for separating suspended dust particles from gas comprises at least one tube through which the gas bearing the dust passes, the particles of dust being charged by friction with the tube, the charged particles then being attracted to an assembly of earthed or charged plates 4 from which the particles fall ready for collection. In Fig. 1, dustbearing gas is given a vortical flow before its entry into an inlet 9 or during its passage through tubes 3 which are supported by a partition 1 between a header 8 and a separation chamber 2. The dust particles fall into collectors 5 and the dust-free gas passes through an outlet 6. In order to reduce the turbulence of the gas within the chamber 2 sufficiently to permit the dust particles to be attracted to the plates 4, the volume of the plate assembly is made greater than one third and less than twice the volume of gas passing through the tubes 3 per second. Fig. 2 shows how the tubes 3 are connected to alternate plates b, d, f, h and to the negative pole of a generator 7 which may produce 10-20 KV; the remainder of the plates are connected to the other pole of the generator. In'Fig. 3 (not shown), the tubes are connected to alternate members of the plate assembly, the other plates being earthed. The plates may be smooth or corrugated or may have recesses. The tubes may be lined with suitable fabric or paint to increase the electrostatic charge imparted to the particles.

As shown, the nipple is provided with an extension 13 having an axial boring and an enlarged diameter portion 14, slots 15 being cut into the extension 13 to allow the portion 14 to be contracted so as to pass down a bore 16 in the shank and subsequently to expand in a larger diameter portion 17 of the bore where it is retained. The plug is locked in position by peening over a flange 21, provided on the head, into recesses 22 in the surrounding structure. A screw-driver may be engaged in a slot 23 cut through the flange 21 and into the head of the plug. Alternatively the slot 23 is replaced by a hexagonal hole for engagement by a key and the plug is locked by centre punching metal of the part containing the bore into recesses in the head of the plug.

Title: Means for sustaining operation of an alternating current powered consumer's installation during periods of transition of supply from a distributing network to an auxiliary power plant
IPC: H02J9/06
Filed: 1954-11-29
Abstract: 760,897. Stand-by supply systems. AKTIEBOLAGET HAGGLUND & SONER. Nov. 29, 1954 [Nov. 30, 1953; Oct. 2, 1954], No. 34554/54. Class 38 (4). In means for sustaining operation of an A.C. load 3 during change-over to a stand-by source 12, 13 following failure of a main source 1, of the kind utilizing the kinetic energy of a flywheel 6 maintained in rotation by energy supplied by the main source, the flywheel is normally driven by a D.C. machine 5 supplied from the main source over a rotary or other converter 4, the D.C. machine functioning, upon failure of the main source, as a generator driven by the flywheel and feeding the load through the converter. The converter and D.C. machine may be provided with regulators 8, 10 for automatically controlling the converter for constancy of output voltage and frequency whilst supplying the load. The converter itself may function as the stand-by generator, the machine 13 being replaced by a clutch, whereby the stand-by engine 12, when run up to speed, is coupled to the converter and drives it. The connection between the main source and the converter and load may include reactors, or condensers, which, in conjunction with a regulator for the converter, allow the load to be supplied at constant voltage, independent of voltage fluctuations of the main source. In other arrangements the load is always supplied through the converter-driven as a generator by a motor fed from the main, or stand-by, source, or by a stand-by engine.

Abstract: 1,240,536. Photographic apparatus. POLAROID CORP. July 9, 1969 [July 9, 1968], No. 34558/69. Heading G2A. Photographic apparatus has a pair of juxtaposed rolls 38, 40 for engaging and moving an exposed film unit from a stack of film units in a container, film advancing means 54 engaging a film unit within the container and moving the unit into engagement with the pair of rolls, driving means for driving at least one of the rolls and driving the film advancing means for reciprocating movement toward and away from the rolls, and disabling means coupled with the roll and the film advancing means for presenting the film advancing means from engaging another of the film units whilst the rolls are moved away from each other by the presence of a film unit therebetween. The film advancing means 54 is pivotally mounted at 56 to one end of an L-shaped member 44 slidably mounted by fixed pins 50 entering a slot 46 member 44 reciprocating under the action of a pin 52, attached to roll 38, entering a second slot 48. An arm portion 60 extends from film advancing means 54, the upper surface of portion 60 being engaged by a spring 60 attached to an intermediate portion of L-shaped lever 44, the lower surface on a ramp 68 mounted by pins 72 on a straddle arm 70. Arm 70 is pivotally mounted at one end, the other end having an inclined surface 74. A second arm 80 is pivoted at 82 has a roll supporting recess 84 at one end to receive an extension of roll 40 and engages a tab 76 fixed on an intermediate portion of arm 70. In operation, film advancing means 54 reciprocates towards and away from the rolls wherever the rolls are rotated, and portion 64 engages a film unit to advance the unit to the bit between the rolls. The presence of a film unit between the rolls pivots arm 80 counter-clockwise and thus arm 70 clockwise, a resilient member 96 being canned by arm portion 74 under the surface of arm 70 to maintain arm 70 and ramp 68 in a position where member 54 cannot engage a further film unit. The next succeeding film unit is exposed upon actuation of the shutter which causes member 98 to contact and pivot member 96 out of engagement with arm 70 to permit means 54 to engage the film unit. The apparatus is used in a camera of the self-developing type.
