Abstract: 1,129,606. Windings fordynamo-electric machines. C. A. PARSONS & CO. Ltd. 16 Aug., 1967 [1 Sept., 1966], No. 39125/66. Heading H2A. In a two-layer or "diamond" type rotor winding, e.g. for a turbo-generator, the endturns are strengthened and circumferentially spaced for ventilation by making them of radially on-edge portions 5, 6, 7' secured separately to the slot-conductors 1, 2, 3. The conductors and end-turns are separated by insulation 4, 8. The end-turns, have projecting tongues 5a, 6a, 7a by means of which they are secured to their respective slot conductors. The strips forming the end-turns are radially tapered or spaced by tapered insulation. This arrangement makes the end-turns self-supporting. The conductors may be cooled by gas or by liquid. Aligned holes in the end-turns may be provided to allow entry of coolant through the winding (9, in Fig. 4, not shown). The end turns may protrude axially by staggered amounts to improve cooling (Fig. 5, not shown). The end windings may have surface grooves for cooling.

Filed: 1961-11-01
Abstract: 921,210. Photographic cameras. AGFA A.G. Nov. 1, 1961 [Nov. 5, 1960], No. 39148/61. Class 98 (1). A photographic roll film camera for producing different size negatives has interchangeable units each of which comprises a picture frame and a film advancing roller. In the embodiment shown in Fig. 2, the unit comprises a carrier with a picture window 30a, and a film advancing roller 16 with tight feed tooth 16a rotatably mounted on arm 30, 31 of the camera. The spindle 17, 19 of the roller is held in borings 14, 20 in the film housing and can be removed by depressing roller 16 against the force of spring 26a. The other end of the unit is locked on to the camera housing by means of sliding guide means, spring clips or in this case pins 34 on the carrier releasably locked into recesses 35 in the housing by a rotatable spindle 36. The image numbers 0-36 are shown by a conventional rotatable disc 40 with a window 41, the disc rotating once during the movement of the entire film. If the unit is replaced with one with a smaller picture frame and only four teeth 16a at each end of the spindle, the disc 40 will rotate twice over the entire film length so that an additional counter 43 is used with two readings 36, 0 one of which is visible in the window 48. Initially the counter 43 is set at 36 but after one rotation of disc 40 a pin 47 on the disc engages projection 46 on counter 43 and rotates it to the " 0 " setting position. The spools 16 may be suitably graduated for their respective film frames in known manner instead of having different numbers of teeth.
Patent GB-391856-A (GB)
Abstract: 391,856. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London. -(Assignees of Materiel Telephonique Soc. Anon. ; 46, Quai de Boulogne, Boulogne, France.) Nov. 6, 1931, No. 30765. Convention date, Nov. 21, 1930. [Class 40 (iv).] Calls from a P.B.X. may be set up either by a dial DL or by a keyset KS transmitting coded impulses, the calls being automatically separated and extended over different sets of finders LF, L<1>F<1> to registering mechanism specially adapted for dealing with the type of impulsing employed. In the system shown, calls are normally established by the operator but when she is not in attendance certain subscribers are plugged directly through to the main exchange. In the latter case, the completion of a substitution loop energizes line relay L to start the finders LF. When the call is found, relays Co, Cok operate over wire c<1>, the latter short-circuiting relay LK. For a call from the P.B.X. operator, key Cc is first operated so that when plug PJ is inserted, marginal discriminating relay LK operates over contacts ccl, e4, and energizes relay A which starts the finders L<1>F<1>. When the line is extended to a register, ground sent back over the b-wire energizes relay E which releases relays LK, A, and lights lamp CL. Ground is also extended over wire d to operate relay Bb which inserts compensating resistances in the a- and b-leads during impulsing. When impulsing is completed, the restoration of key Cc releases relays B, C, D, causing the transmission to the register of a signal consisting of 48-volt battery on the a-wire and 60-volt battery on the b-wire to initiate the control of the selectors. The connection of the P.B.X. subscribers to the junction and the transmission of the discriminating signal may be entirely automatic. The operator may also have a dial for emergency use.

Title: Ceramic materials with open porosity
IPC: B01D39/20
Filed: 1973-08-24
Abstract: 1408998 Moulding porous ceramic bodies BATTELLE-INSTITUT eV 24 Aug 1973 [31 Aug 1972] 40231/73 Heading B5A [Also in Division C1] Ceramic materials having an open pore structure are produced by a method comprising (a) providing a core defining the pores and interconnecting passages by sticking together spherical bodies, (b) casting a ceramic material around the core, (c) hardening the ceramic material and (d) removing the core. The ceramic material may be glass ceramic, glass, nitrides, oxides, silicides or borides. In one example, a core is produced by packing polystyrene balls into a hollow cylinder, and contacting the balls with a solvent so that their touching surfaces adhere to form "bridges" between the balls. A slip of a mixture of alumina and silica is cast around this core, the water removed from the slip to partially harden the ceramic mixture, and the polystyrene depolymerized by heating to remove the core structure. Further heating to 1600‹ C. provides final hardening of the ceramic mixture which reacts to form mullite. The core may alternatively be produced by sticking together pore forming bodies with adhesive or by sintering. Suitable materials for the bodies include soluble or low melting salts, plastics, wax, metals or alloys. The products are suitable for use as filters or gas heated radiant elements.

IPC: B65B27/08
Filed: 1959-11-26
Abstract: 911,677. Wrapping envelopes. UNITED STATES ENVELOPE CO. Nov. 26, 1959, No. 40266/59. Class 94(1). Batches of envelopes are forwarded against wrapper bands which are folded rearwardly about opposed batch front edges, the batches then operating devices which fold the band ends into overlapping relation on their trailing faces. Envelopes are delivered by wheels 1 as described in Specification 708,612, against spring pivoted holding members 14, 19 and are counted by photo-electric means 27, 54. When the desired batch has collected, the counter causes operation of an electro-magnetic one revolution clutch, Figs. 2, 3 (not shown), whereby a wrapping cycle is initiated. Pusher bars 74 movably cyclically by crank means 57-61, 63, 64, 67, thrust the batch against a band B, the latter being fed from a supply 76 by rollers 84, 100 and being severed at or just before contact with the batch, by knife means 127, 142. At the same time, the member 133 bearing the moveable knife displaces a ball valve 131 to permit a spot 144 of adhesive to be placed on the band. The band is located for pick-up by the batch by fork arms 147 of spring biased latch members 145 pivoted in plates 9 and 10 defining the path of travel of the batch, the batch engaging the sloping surfaces of the arms to pivot the latches out of its path. Latch surfaces 149 fold the band about the top and bottom faces of the batch and when the latter has cleared the latch steps 150, the latches snap inwards to fold band extensions d, e on to the trailing face. The steps 150 are displaced slightly longitudinally to ensure sequential folding down of the extensions. An oscillating member 162 pushes forwards the upper edge of the batch to ensure its clearing the upper step. As each batch is pressed against that preceding it, so pressure is applied to the overlapped extensions to cause adhesion. The machine is fully adjustable for different envelope and batch sizes. Specifications 715,644, 746,695, 809,349 and 812,590 are referred to.

Abstract: 974,769. Multi-stage flash-type evaporators. AQUA-CHEM Inc. Nov. 17, 1961 [March 10, 1961], No. 41210/61. Heading B1B. In an evaporator comprising a horizontal shell 11 divided by walls 12 into two or more flash chambers connected in series by liquidflow passages 17 beneath the lower ends 15 of the walls 12, each chamber has a weir 24 arranged so that the horizontal plane of the upper, end of the weir is below the horizontal plane of the lower end 15 of the wall 12. To prevent the passage of vapour from one flash chamber to the next, the upper level of the liquid in each chamber is maintained at or above the horizontal plane of the lower end 15 of the wall 12 by controlling the rate of flow of liquid through each passage 17 by means of plates 26 which can be moved up and down in channels 27 secured to the wall 12. These plates 26 also cause the flow of liquid to become highly turbulent thereby improving the efficiency of flashing in the subsequent flash chamber. Each weir may be provided with a shelf (not shown) extending horizontally towards the adjacent passage 17. The apparatus may be used for the distillation of sea water.

Abstract: 967, 494. Automatic temperature control. GARRETT CORPORATION. Dec. 1, 1960 [Dec. 2, 1959], No.41389/60. Heading G3R. In a method of controlling the flow of cooling fluid to a load, e.g. electrical equipment, whose temperature is to be controlled, a thermistor having heat dissipation characteristics similar to those of the load is disposed in the fluid flow, and variations in the thermistor resistance are used to control the flow of fluid to maintain the load temperature constant. As shown, a resistance bridge 1 comprising fixed resistors 2, 3, an adjustable resistor 4 and a thermistor 5 is fed from a constant direct voltage source so that the thermistor 5 operates in its self-heating region, i.e. that zone in which internally generated heat causes appreciable temperature rise and appreciable resistance change in the thermistor, and the output of the bridge, which in magnitude and polarity is determined by the resistance of the thermistor 5, is fed through an amplifier 9 to an air control 11. The thermistor 5 is matched to the load whose temperature is to be controlled so that the amount of cooling air required to maintain the thermistor resistance at a pre -selected value is also sufficient to remove rejected heat from the load.

Abstract: 1,149,040. Centrifugal blowers and pumps. TURBON VENTILATOREN-UND APPARATEBAU G.m.b.H. Sept 20, 1966, No.41878/66. Heading F1C. For the purpose of reducing noise in a centrifugal blower or pump, the collecting chamber situated between the impeller and the outer wall of the casing is partly divided into two parts radially by an intermediate wall the effective width of which increases with increasing angle encircling the impeller so as to occupy increasingly more of the width of the casing between the side walls. In the blower shown in Figs. 4 and 5, having a rectangular sheet-metal casing 21 provided with an inlet 22 and an outlet 23, the air collecting chamber surrounding the impeller 24 and afforded by the casing is partly divided into two parts by an intermediate wall 25. The wall 25 may be of the full width of the casing 21 from the end 126 adjacent the outlet 23 up to a line 27, and thereafter becomes progressively narrower, terminating at the other end 28 at about 270 degrees from the end 26 in a gentle curve towards the front wall of the casing. Instead of being concentric with the impeller 24 between the line 27 and the end 28, the wall 25 may be of spiral form. The rectangular casing may be replaced by one of normal volute form, Figs. 1-3 (not shown), and the intermediate wall, which extends concentrically around the impeller for nearly 360 degrees, may be divided into two separate walls, each of half the casing width at the beginning and tapering progressively in width towards the other end whereby the space between the walls progressively increases in width from zero to the full width of the casing. In a centrifugal pump for liquids, Figs. 6 and 7 (not shown), the width of the intermediate wall decreases either continuously with a constant or variable slope or discontinuously in a number of separate steps. The intermediate wall may vary in thickness so that the cross-sectional area of the collecting chamber increases in the direction of flow.
