Title: Improvements in apparatus for taking kinematographic photographs
IPC: G03B15/08
Filed: 1920-07-06
Abstract: 147,021. Rothe, A. von. March 29, 1919, [Convention date]. Kinematograph apparatus.-In apparatus for taking kinematograph pictures of near objects, more particularly for photographing surgical operations, the spool boxes are placed at a distance from the camera so as to reduce the dimensions of the apparatus in the neighbourhood of the object and ensure good light. As shown in Fig. 3, the camera 1 is attached to the bottom of a rod 15, and the spool boxes 4, 5 are carried by members 26 secured to the rod, the film passing down and up channels 2, 3 respectively. The rod 15 is adjustable longitudinally and rotatably in a tube 17 carried by girders 16 above a glass ceiling 45 of the operating room, the whole apparatus moving with it and being counterbalanced by a weight 40. The camera may be turned about a pivot 14 to alter the photographic axis, and the film may run over rollers 54 within a bellows 52, or through a jointed tube 53, each arrangement enabling the camera to be turned without affecting the film. Motors and gearing may be provided for effecting the necessary movements. In a modification, Fig. 7, the camera is housed in a cylindrical casing 55 capable of being turned within a ring 56 secured to the rod 15. The lens tube 22 projects through a slot 58 in the ring, and the film passes over rollers 67 - - 72, and through a slot 73, to and from a single channel 23 within the tube 17. The spool boxes are arranged one above the other, and complete rotation of the apparatus is possible round the axis of the rod 15 without obstruction by the girders 16. The camera may alternatively be carried by arms 12, Fig. 6, inclined at an angle of 45 degrees to the axis of the rod 15 so as to enable it to be turned through a complete right-angle. Various modifications may be made in the arrangement of the spool boxes and film channels. The film may be prevented from completely running-off the paying-out spool by means of a pivoted arm 85, Fig. 7, which rests on the film and closes a switch 84 to complete an alarm circuit or break the motor circuit through a relay circuit. The switches for the motors may be placed in such a position that the surgeon can operate them with his feet. The image on the film may be observed by means of a mirror 75, Fig. 12, and a prism 77 in a tube 76 having an eye-piece 78 and a self-closing shutter 79, the tube being rotatable about an horizontal axis. A hand-wheel 80 on a sleeve 81 carrying a bevel-pinion 82 engaging a bevel-pinion 83 enables the image to be focused.

Title: An improved method of centrifugal separation and apparatus for use therein
IPC: B04B15/02
Filed: 1938-06-30
Abstract: 516,600. Centrifugal separators. GLUD, G. E. June 30, 1938, No. 19450. Convention date, July 1, 1937. [Class 23] [Also in Group III] A waxy or like solid substance is extracted from a liquid by subjecting the mixture to a centrifugal separation, and applying local heat to the separated solid substance to liquefy part of it ; it is then subjected to a second centrifugal separation to remove any of the original liquid which may have been retained by it. The process used for the extraction of stearine, is carried out in a separator of the type shown. A partition 28 is arranged in the bowl 11 outside the usual conical discs, and this divides the bowl into two chambers 6, 8. The outer chamber 8 has a ring 19 near its lower end which leaves only a small gap outside the partition 28 for the passage of material. The mixture to be treated passes from the funnel 2 to the base of the bowl then through the apertures 4 to the separating chamber 6. The separated oil passes upwards to its outlet 10 and the stearine is deposited on the partition wall 28 from which it passes to the heated chamber 8 where it is liquefied. It then passes to its outlet 9 while any oil separated in the chamber 8 finds its way back through the solid stearine to the chamber 6. Water for heating the chamber 8 is supplied from the pipe 21 to the annular chamber 20 and pipes 23 which direct it to the bowl wall 1 ; it is discharged through outlet pipes 24 and an adjustable outlet 26. The outlet 9 for the liquid stearine is arranged closer to the axis of the bowl than the oil outlet 10. The pipes 23, 24 may be connected so that hot water may circulate without escaping into the chamber 8, or the heating of the stearine may be effected electrically.

Title: Improvements in and relating to electric battery charging systems
IPC: H02J7/22
Filed: 1935-07-11
Abstract: 446,228. Charging batteries ; automatic control systems. FORD MOTOR CO., Ltd., 88, Regent Street, London. July 11, 1935, No. 19810. Convention date, Oct. 29, 1934. [Class 38 (iv)] Relates to battery-charging systems including a battery 23, an electric generator 10 adapted to supply current at two different rates, a charging rate regulator 25 with vibrating arm 26, a cut-out 16 and thermally responsive means 34, 36 for varying the charging voltage in accordance with temperature changes. The generator 10 is provided with a shunt field winding 11 which is directly earthed by the opening arm 26 of the regulator 25 to give the high charging rate and is earthed intermittently through resistances 14, 15 to give the low charging rate as the arm 26 vibrates. As the generator 10 speeds up, the points 18, 19 of the out out are opened by the voltage winding 20 and the battery 23 is charged at the high rate through the cut out current winding 21 and the regulator winding 30 which tends to open the points 27, 39. Such opening of the points does not take place until current also flows through the winding 28 on the battery becoming fully charged and the charging voltage attaining a value corresponding to atmospheric temperature. The thermally responsive means comprise two bi-metallic arms 36, 34 insulated from one another and carrying co-operating contacts, the upper arm 36 having a heating winding 40 which renders it responsive to generator voltage, while the lower arm 34 responds only to atmospheric temperature. When the battery is fully charged and the voltage rises to the value corresponding to the temperature, the points on the arms 34, 36 close and current flows through the winding 28 of the regulator ; the points 27, 39 then open so that the generator field 11 is grounded through winding 15 and the charging rate is reduced. Winding 15 is opposed to windings 28, 30 so that arm 26 vibrates. Vibration of the bi-metallic arm 36 is checked by a heating winding 37 thereon in series with winding 28. When sufficient lights 22 are switched on, the current through winding 30 is reduced or may even be reversed and the charging takes place at the high rate whatever the condition of the battery.

Abstract: 147,811. British Thomson - Houston Co., (Assignees of Goldsmith, A. N.). June 15, 1918, [Convention date]. Transformers.-Receiving coils for wireless signalling have their resonance frequency determined by their distributed capacity and inductance, and means are provided for adjusting the resonance frequency. The receiving-coil may be connected to a pair of valves in cascade, the inter-valve transformer having its secondary formed similarly to the receiving-coil..Figs. 5 and 6 show two constructions of coil. As shown in Fig. 5, the coil is formed in three portions 16, 17, 18 connected in series and arranged radially round a common centre, about which they may be turned, so as to vary the distributed capacity and inductance. The coil-sections may be arranged coaxially and moved parallel to themselves for adjustment. As shown in Fig. 6, the coil-sections are parallel but not co-axial, and are adjusted by moving alternate sections out of line with the others. Two such coils may be adjusted simultaneously by the use of a common operating-bar 41. Fig. 8 shows a receiving-coil 33 earthed at one end and connected across the grid and filament of a valve amplifier 34, the plate circuit of which is coupled to a coil 36 of the kind described above which is connected in the grid circuit of a second amplifier 37. Resonance in the coil 36 results in an increase of the potential variations applied to the grid of the valve 37.
