Patent GB-680286-A (GB)
Title: Improvements in and relating to photo-sensitive inspection devices
IPC: G01N33/00
Filed: 1949-06-01
Abstract: 680,286. Photo-electric detecting devices. SARGROVE, J. A. Aug. 31, 1950 [June 1, 1949], No. 14698/49. Class 40 (iii). An arrangement for inspecting nominally clear liquids contained in transparent containers to detect the presence of minute particles of impurities comprises means for passing light through the container to a photo-sensitive cell, the container being fixed relative to the photosensitive device, and means for inducing motion of the liquid with respect to the container. The invention is of particular value for the inspection of clear liquids in glass ampoules or bottles where minor imperfections in the glass would produce effects of the same order as, or greater than, those produced by particles in the liquids if normal light scanning test methods were used; thus leading to the necessary rejection of slightly blemished containers filled with clear liquid. In one embodiment the ampoules or bottles 1 are fed on to a conveyer comprising a series of platforms 2 sliding on rails 3 and centrally joined by universal couplings 5. The containers are moved forward intermittently so that each in turn passes on to an optical bench assembly 6, the rails 3a on the bench being separate from those on either side of it. Light from a source 7 is directed through the container and through a fine grid 8, which is preferably a ruled grating or one prepared photographically, and is then directed by lens 9 to photo-cell 10. The bench 6 is arranged to pivot about the axis of couplings 5 and is rocked by means not shown when the conveyer is stationary. This causes the liquid in the container to move relative to the optical units and the image or shadow of any particles in the liquid move across the grid causing variations in the photo-cell output. Shadows caused by blemishes in the container however do not move and thus cause no variations in the output. The cell output is fed through a filter removing low frequency cornponents to a trigger network 12 which derives a constant input to the control amplifier 13 when A.C. components are present in the photo-cell output. Amplifier 13 may be used to operate an alarm circuit 14, automatically operate a rejection device 15, and/or give an indication on cathode-ray tube 16.

Patent GB-653243-A (GB)
Title: An electrical load control system
IPC: B23K11/24
Filed: 1947-06-05
Abstract: 653,243. Control systems for consumption apparatus. BUDD CO. June 5, 1947, No. 14847. Convention date, June 14, 1946. [Class 38 (iv)] Thermionic (and like) control.- The current in an A.C. welding load circuit, which is interrupted by a device 25 upon abrupt voltage change at the weld point upon weld fusion, is progressively varied during the period of application by automatic shifts of the phase of the grid potentials of valves 11, 12 controlling the firing instant of a pair of backto-back ignitrons 9, 10 in the load circuit according to the potential across a charging or discharging condenser so as to vary the fraction of successive half waves of the load current. The phase shift is effected through a transformer 35 included in an A.C. bridge 30 which has included in one arm the A.C. winding 34 of a saturable choke, the D.C. winding 36 of which is supplied with current through valves 39, 40, the grid potentials of which are dependent on the potential across a condenser 59. To obtain a progressive increase in load current a falling grid potential to valves 39, 40 is derived from a D.C. bridge 54 comprising two parallel arms, each having respectively a constant potential discharge device 65, 68 and a resistance 66, 67 and reversely connected, with a potentiometer 69 connected between the functions of the discharge devices 65 and 68 and associated resistances, the slider of which is connected to valve grids 41 and 42 ; connection to the cathodes of valves 39, 40 being made through a potentiometer 73, in series with a resistance 72 shunted across the discharge device 65. The D.C. bridge is energized during the non- welding period from a rectifier 46. When the welding period is initiated by valve 16 a relay 19 opens contacts 53 and 58 and closes contact 60 so that the bridge is then energized by a precharged condenser 59 thereby providing a falling potential to grids 41 and 42. Progressive decrease in the load current during the post-weld period, for annealing the weld, is provided by the circuit shown in Fig. 2 which is substituted between the terminals 95, 96, 97 and 98 in Fig. 1. The grids 41, 42 are normally maintained at a potential corresponding to that existing between points 90 and 94 and upon initiation of the post-weld period, contact 84 is closed resulting in the potential across the condenser 90a increasing to that across points 86 and 94 at a rate determined by the setting of resistance 93. This latter circuit may also be used to obtain the progressive increase in load current by arranging for the contact to be normally closed but opened upon initiation of weld period and thereby provide a decreasing potential to the grids 41 and 42. The device 25 (Fig. 1), may be as described in Specifications 606,958 and 642,468, and may be supplemented by a timing circuit comprising a valve 17 which disconnects the load circuit after a predetermined number of cycles in the event of the device 25 not operating within this period.

Abstract: 900,138. Gyroscopic apparatus. BENDIX CORPORATION. April 25, 1961 [April 29, 1960], No. 14859/61. Class 97 (3). [Also in Group XXV] A rate of turn gyroscope comprises a rotor case 14 mounted in its fixed frame by torsion members 30, 32 connected between the arms 26, 28 of the rotor case and members 9, 10 of the frame, the members 30, 32 being such that they axially expand and contract when torsionally deformed and being arranged so that when one member is torsionally deformed causing axial expansion the other member experiences a corresponding contraction. The member 30 or 32 is formed by a tubular member with helical slots 82 and round holes 84 at the ends of the slots, the width of the slots besides allowing torsional deformation also acting as limiting stops to rotation in one direction, and with screw threads 86, 88 for fixing it to the rotor casing and the fixed frame. Alternatively, the helical slots may be replaced by straight cut or angular slots (Fig. 4, not shown). The rotor element 50 of the output signal generator is located on the arm 26 and co-operates with the stator element 52. The movement of the casing 14 is damped by the cup 62 of magnetic material fixed to the arm 28 and the permanent magnet 64. The bearings 70, 72 which do not normally support the mountings 30, 32 do so to limit radial deflection under high stress and extreme vibratory conditions. The rotor casing 14 houses the rotor 16 which rotates about the shaft 20 and is driven by an electric motor 22.

Patent GB-423083-A (GB)
Title: Improvements in and relating to the manufacture of fermented beverages and medicinalpreparations
IPC: C12P1/00
Filed: 1934-05-22
Abstract: In the manufacture of beverages produced by fermentation such as beer, wine, and spirits, paraffin or other non-injurious hydrocarbon oil is employed for certain specific purposes.  In the first place, the precipitation of coagulable proteins may be assisted by treating the wort with a small quantity of the hydrocarbon oil.  According to another process, a large proportion but not all of the hop essentials from finely broken up hop cones is extracted therefrom by treatment with a small quantity of hydrocarbon oil, preferably white oil, and hot water, the resultant oily extract being removed from the mixture, the residual mass added to the wort to assist the precipitation of coagulable proteins and of hard resins, and the oily extract added to the wort shortly before the copper is "cast" into the hop back, or to the gyle in the fermenting vessel, or to the finished beverage at the stage when it ordinarily undergoes dry hopping. According to a further process, the fermenting liquid is protected from contamination by atmospheric influences by covering it after or during the process of seeding it with the fermenting micro-organisms with a layer of hydrocarbon oil, aeration and/or stirring being employed occasionally if desired.  The separated layer of oil containing yeast or other fermenting organism can be employed for medicinal purposes.

Title: Improvements relating to attenuators for electric waves
IPC: H01P1/22
Filed: 1945-06-14
Abstract: Sintered films comprising two noble metals such as platinum and palladium are connected in series or shunt in coaxial lines or wave-guides for alternating ultra-high frequency electric transmissions.  The films are thin in comparison with the depth of penetration of the skin current, and may be 100 angstroms thick; their resistance is consequently independent of frequency and has a low temperature coefficient.  A Pyrex or quartz tube or the like is coated with a resinate solution of noble metals, such as platinum and palladium in atomic proportions of 1.5 : 1 or 1 : 1, and baked for about 7 minutes at 630\sB40 DEG C., the resistance increasing with the duration of the baking.  Low-resistance conductor rings are then applied to the ends of the tube by baking metallic paste or solution.

Filed: 1920-06-04
Abstract: 172,342. Bloxam, A. G., (Akt.-Ges. f³r Anilin Fabrikation). June 4, 1920. Developing; relief photographs.-For the production of photographic reliefs, exposed silver salt colloid sheets are developed with polyhydroxybenzene developers without ammonia, and with a very reduced quantity of preserving-agent or alkali in order that the oxidation products of the developer may harden the colloid corresponding with the reduced silver and without spreading, the soluble colloid being dissolved away. If a preserving-agent such as sulphite is included, it must not exceed half the weight of the polyhydroxybenzene, and if an alkali carbonate is included it must not exceed ten times the weight of the polyhydroxene. Four examples of developing-compositions are given. Alternatively, a non-tanning developer mav be first used, the sheet exposed again and developed with a tanning developer as above, in which case there is an inversion of the image. The relief obtained may be dyed. The sheets may be dyed previously, or dyes or pigments may be added to the emulsion. Exposure may be given from the front and the exposed sheet transferred, or exposure may be made through the support. The sheets may contain compounds which absorb actinic rays to control the action of the light during exposure.

Abstract: 839,032. Sighting apparatus. SPERRY CORPORATION. March 24, 1944 [March 25, 1953], No. 15211/48. Divided out of 839,031. Class 92 [Also in Group XX] An adjustable reticle for optical devices, such as gun sights, comprises a conical surface so illuminated by a light source which is adjustable along the axis of the cone, as to present a luminous band which is geometrically similar to the cross-section of the cone and has its linear dimensions dependent on the adjustment of the light source. The device is described for use in the gun sighting mechanism of Specification 839,031, and as diagrammatically shown in Fig. 2, consists of a fixed conical reflecting surface 138 and a movable annular illuminant 142 whose position is determined by a cam 143 to vary the size of the circular band reflected by surface 138 through a lens 200, mirrors 87, 87<SP>1</SP>, and thence to the observer's eye 100. The cam is translated by a target dimension knob 30 and rotated by a shaft 28, and the arrangement is such that when the reflection as viewed through the mirror 871 just circumscribes the target, the position of the shaft 28 is a measure of a function of the target's range. As shown in Fig. 4 the light may emanate from a lamp 192 near a parabolic mirror 216 from which parallel rays are directed on to a parabolic reflecting surface 193<SP>1</SP> which concentrates the rays on to a thin ring 204 of diffusing material. This ring is located in a gap between opaque members 195 and 203, and surrounds the conical reflecting surface 201. Four small slits 223 may be formed in the member 203 and are fitted with bars 222 of diffusing material, thus providing radial reticle lines in addition to the circle. In a modification, Fig. 3 (not shown), the parabolic reflecting surface is formed on a transparent body through which the light rays are directed and whose outer surface is silvered.
