Title: Improvements in and relating to cloches, hutments and like structures of tent or barn shape
IPC: A01G13/04
Filed: 1944-06-12
Abstract: 583,101. Portable shelters and cloches. EDWARDS, G. J. S. June 12, 1944, No. 11189. [Class 20 (i)] A frame unit for a portable shelter or cloche of tent or barn shape comprises two or more longitudinally slotted bars pivotally connected and clamped in the required angular relationship by means such as a nut and bolt passed through the slots of adjacent bars, the slots in the bars locating and retaining panels forming the sides of the shelter. The Figure shows a tent cloche according to the invention comprising a pair of frame units each formed of two slotted bars 1, 2 clamped by a nut and bolt 3, 4 and a number of glass panels 5, 6 located in the slots 1a 2a of the bars. As shown a number of glass sheets are shown held in overlapping relationship by S-clips 7 but they may be secured by wedges or the sides of the cloche may be of single sheets. A three sided or barn cloche can be made by using more slotted bars and clamps to build up the required shaped section at each end. Three or more bars may be held together by one clamp where for example two adjacent cloches have a common wall. In a modification a single rod having screwed end portions may replace the bolts of two spaced apart units, the rod determining the spacing and also serving as lifting means.

Title: Improvements in or relating to electrical phase detectors
Inventor: WAYMAN CECIL JOHN
IPC: H03D13/00
Filed: 1959-01-12
Abstract: 923,655. Transistor circuits. GENERAL ELECTRIC CO. Ltd. Jan. 11, 1960 [Jan. 12, 1959], No. 11254/62. Divided out of 920,535. Class 40 (6). [Also in Group XXXVI] A phase detector circuit for determining the phase relationship between input signals at IL and RL includes a bi-stable circuit BC the state of which depends on the phase relationship between the input signals, the signal at IL varying the relative impedances of the two input paths (C2D2, C3D3) over which the signal at RL is applied to BC, so that the amplitudes of the pulses applied to the bases of T4T5 respectively will be different, the state of BC being dependent on which of these pulses has a larger amplitude. T2 will be conductive for negative cycles of the input at IL and T3 for positive cycles, and pulses of different polarity but of the same amplitude will appear at the collectors of T2, T3. When T2 is conductive, D2 will be more conductive than D3 and transistor T4 will either be cut-off or remain cut-off depending on its previous state, and when T3 is conductive D3 will be more conductive than D2 and T5 will be cut-off. Therefore, if the signals are in-phase, that is, the positive pulses derived from alternate cycles of the signal at RL correspond to the positive cycle of the input at IL, then T4 will conduct and T5 will be cut-off therefore giving a negative output at OL. In the antiphase condition T4 will be cut off and T5 conduct thus giving zero output at OL. The mean D.C. levels of the pulses appearing at the collector outputs is kept the same by the provision of a stabilizing circuit consisting of R7, R8 and C1.

Title: Improvements in apparatus for giving change for notes
IPC: G07D1/02
Filed: 1919-05-08
Abstract: 144,851. Evans, C. A. D., and Rawlings, H. B. May 8, 1979. Money-delivering apparatus.-In apparatus for giving change for notes, the note is presented through a slot to a system of endless bands which are caused, by the rotation of a shaft, to carry the notes in stages to the back of the machine and the note drawer, the rotation of the shaft at the same time operating mechanism which opens a drawer carrying with it the lowermost of a pile of change cups. The drawer-opening mechanism comprises a slide g which, on being pushed inwards, moves a shutter h so as to uncover the note slot s. At the same time, a pawl k engages a tooth g<1> on the slide, and a plate g<2> pivoted on the slide drops behind the arm j of a pawl j' which is in engagement with teeth f<3> on the change drawer f. On the rotation of a shaft m, the endless bands n, p are actuated to draw the note into the apparatus, and an arm m<2> on the shaft engages the arm l and disengages the pawl from the tooth g<1>. The slide is then pushed outwards by a spring g<4>, the plate g<2> thereby disengaging the pawl j<1> from the change drawer, which is then pulled open by a spring f<2>, carrying with it the lowest of a pile of change cups d contained in a tube c. A spring-controlled stop g<5> is mounted on the slide g, and a ring m<3> is mounted on the shaft m in the path of said stop. The ring m<3> is flattened at one part m<4> to allow the stop to pass when the slide g is pushed in. This arrangement ensures that the shaft m is in the correct position before the slide can be operated. When the apparatus is arranged for changing more than one denomination of note, the shutters h are connected by a cord or chain of such length that if two slides g are pressed in simultaneously both shutters h will be moved, but not sufficiently to unblock either opening s. The slides g are arranged to actuate counting-mechanism i visible from the exterior of the apparatus. A cam may be keyed to the shaft m and arranged to ring a gong each time the shaft is operated. The mechanism for drawing the note into the apparatus may consist of two pairs of endless bands n passing over rollers o, o<1>, o<2>, o<3>, o<4>, one pair near each end, and between the bands n of each pair is an endless band p passing over rollers o<3>, o<4>, o, o<1>, q, q<1>, q<2>, each note being thus gripped by two assemblages of three bands. The rollers o are driven by sprocket wheels r<1> from the shaft m. In place of two assemblages of three bands, the notes may be gripped by a flat band extending the whole length of the rollers in conjunction with two smaller bands near to the edges of the flat band. The note is first drawn behind a window a<1>, then carried to the back of the apparatus, and then deposited in a drawer b.

The optical printing apparatus 12 shown is for printing from a first film 2 Fig. 5 having a single row of picture frames 4 extending the length thereof, on to a second film 8, wider than the first, to form a first row of picture frames 10. Both films are advanced intermittently in the directions shown. When the first row has been imaged on to the film 8, it is moved transversely and its driving means reversed so as to expose a second row of frames 10 parallel to the first but with the action sequence thereof progressing in the opposite direction. Film 2 is mounted in a projector 14 Fig.1 and counters 26, 28 set to indicate numeral 1. Film 8 from a cartridge 34 is threaded between reels (36), (38) Fig.2 (not shown) via an exposure station. A wheel 58 is turned to position a platform 56 at its lowest position, which platform carries a guide 48 for guiding the film in the exposure station. A plate (68) Figs.3, 4 (not shown) of the guide has an elongated slot one frame wide, and in this slot is mounted an aperture member 60 fixed relative to the apparatus. The plate (68) slides relative to the member 60 which has an aperture (144) defining the area of film 8 which is exposed. Members 24, 118, 120 are set for the desired direction of movement and the machine started. The film 8 is advanced by pins (92) Fig.3 (not shown) which move in a square path, there being pins (138) engaging the film to hold it steady for exposure when the pins (92) have withdrawn from contacts with the film 8. A shutter (146) is provided. When the number of frames to be printed in the first row is approached, the machine is stepped manually. Then the lever 118 is operated to reverse the drive of all mechanism on the platform 56 which is manually raised so that a second distinct row of frames is exposed on the film 8.

Title: Improvements in and relating to fluid operating mechanism for electric circuit breakers
IPC: H01H33/32
Filed: 1941-09-10
Abstract: 548,520. Fluid-pressure servomotor control systems. BRTITSH THOMSON-HOUSTON CO., Ltd. Sept. 10, 1941, No. 11606. Convention date, Sept. 12, 1940. [Class 135] [Also in Group XXXVII] A pneumatically-actuated circuit-breaker, preferably of the gas-blast type for example, as described in Specification 544,017, [Group XXXVII], is adapted for trip-free opening and high speed reclosing by the provision of a dumping valve or valves between the source and the operating motor, the valve or valves being operated by the back-pressure set up on reversal of the motor to exhaust the back-pressure to atmosphere. The movable contact 17 is connected to the operating piston 23 by a rod, the two parts 24<SP>1</SP>, 24<SP>11</SP> of which are inter-connected by a lostmotion device 25. When the piston 23 is raised in response to opening-fluid pressure, a projection 30 engages a lever 26 which trips a latch 27 normally retaining the contact 17 in closed position. An opening spring 28 and balancing spring 281 charged by the closing movement of piston 23 thereupon expand to aid the fluid-means to open the switch. The fluid is admitted to the cylinder ends through opening and closing valves 33, 34 operated by electromagnets 37, 41 against the action of springs 35, 39 acting on levers 36, 401. Lever 401 comprises two co-pivoted parts, 40a, 40b normally latched together at 43 so as to move as one lever. The latch 43 is trippable by a rod 45 when solenoid 37 is energized by closure on to a fanet, thus enabling spring 39 to close valve 34 and open a port 42 to exhaust the pipe 50. In this way a valve 47, which is held on its seating by a light spring 48 and by the incoming-fluid pressure, is pushed back by the back pressure set up in the large space 46 by the reversal of piston 23 so as to enable the pressure to exhaust through ports 51. A similar valve 53 and ports 57 are provided in order to enable high-speed reclosure of the switch. The Specification as open to inspection under Sect. 91 refers also to Specification 1536/41.' This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to a paper jogger
IPC: B65H31/40
Filed: 1946-04-17
Abstract: 687,471. Vibrating table for jogging paper sheets. STEVENS, A. H. (Syntron Co.). April 17, 1946, No. 11840/46. Class 100 (i). [Also in Group XXXV] A stack of paper sheets is jogged to bring the edges into alignment, by supporting the stack with the sheets held vertically, as by hand, upon a horizontal table 12 resiliently supported by spaced rubber members above a heavy base 1, the table having mounted on its underside a motor comprising an armature member 16 and field members 9, 14, one of which members is resiliently attached to the table so that energisation of the field coil 9 by alternating current causes the table 12 to vibrate in a rectilinear path normal to the table. As shown, the base 1 comprises end castings 2 connected by rails 3 supported by springs 4 and enclosed by a sheet-metal cover. Brackets 10 attached to the castings 2 each carry a pair of rubber members 11, shaped in section as a parallelogram and vulcanised to angle members, which support the table above the castings. The base 13 of the motor is mounted on the table midway between the members 11 and carries the field member comprising a T-shaped core 14 of laminated soft steel and the coil 9. The armature 16 is supported from the table by rubber members 15 similar to the members 11, which members 15 may be so arranged that the armature and field do not contact during operation. If, however, it is arranged that impact occurs, the contacting surfaces are made of hard steel alloy. The rubber members 11 are tuned so that the vibrating part of the structure has a natural period of vibration differing by a few cycles per second from the frequency of the alternating current employed, and a rheostat is provided so that the magnitude of the vibrations may be varied. A resiliently-mounted rectifier 8 may be included in the circuit or a permanent magnet may be employed as the armature so that the table vibrates with a frequency equal to that of the current supply, instead of at double the current frequency. Specifications 505,755, 509,818 and 635,028, [all in Group XXXV], are referred to.

Title: Improvements relating to photographic emulsions
IPC: G03C1/053
Filed: 1940-07-19
Abstract: 542,703. Photographic emulsions. KODAK, Ltd. (Eastman Kodak Co.). July 19, 1940, No. 11908. [Class 98 (ii)] A photographic plate, film, or paper is coated with a sensitive silver halide emulsion in which there is present as protective colloid a polyvinyl acetate containing from 59 to 71 per cent by weight of acetate, calculated as vinyl acetate, the remainder of the molecule being substantially polyvinyl alcohol. The polyvinyl acetate is soluble in a mixture of water and an organic solvent. The polyvinyl acetate should preferably have a molecular weight not greater than 15,000, although after the silver 'halide has been dispersed in a polyvinyl medium, an aqueous solution of a polyvinyl acetate of molecular weight greater than 15,000 may be added. The emulsion may be prepared by running aqueous solutions of silver nitrate and alkali metal halide into a solution of polyvinyl acetate in water and an organic solvent. The organic solvent may be acetone, ethyl alcohol, dioxane, or the monomethyl or monoethyl ester of ethylene glycol. After warming to cause better dispersion and to increase the speed, cooling, and dye-sensitizing, the emulsion is coated on a support and dried in a current of warm air. A solvent such as alcohol, acetone, the monomethyl or monoethyl ester of ethylene glycol, pyridine, dioxane, or morpholine may be added to the developing and the fixing baths. Potassium cyanide may be added to an ordinary fixing bath. With a paper support, the amount of sensitizing dye used should be insufficient to cause staining. In example (1), hydrolysed polyvinyl acetate containing 71 per cent acetate is dissolved in acetone and water. Aqueous solutions of silver nitrate and of potassium bromide and potassium iodide are simultaneously run in to the polyvinyl acetate solution, and a further quantity of polyvinyl acetate solution is added. The emulsion is heated for 20 minutes at 40‹ C., washed, pressed and dissolved in a mixture of acetone, water, and the monoethyl ester of ethylene glycol. Monacetin is added, and the emulsion is sensitized with 2:31-diethyl-41-methyloxathiazolocarbocyanine iodide. In example (2), aqueous solutions of silver nitrate and of potassium bromide, potassium chloride, and potassium iodide are simultaneously run into a solution of hydrolysed polyvinyl acetate containing 59 per cent of acetate in acetone and water. A further quantity of polyvinyl acetate solution is added, the emulsion is heated for 20 minutes at 40‹ C. and is dye-sensitized as above.
