Title: Improvements in or relating to photographic apparatus
IPC: G03B27/465
Filed: 1930-09-15
Abstract: 355,540. Photographic apparatus for copying documents. KODAK, Ltd., Kodak House, Kingsway, London. -(Assignees of Hopkins, R. S. ; 1447, St. PaulStreet; Rochester, New York, U.S.A.) Sept. 15, 1930, No. 27457. Convention date, Sept. 18, 1929. [Class 98 (i).] The shoot 3, Fig. 1, into which the document is inserted is fitted with a spring- controlled pivoted wall or member 23 having a limited movement, which acts as the control member of a spring clutch. This clutch, when released, couples a continuous main drive with mechanism to feed the document into position for exposure and synchronously operates a camera, the clutch being automatically thrown out of action after one revolution. On inserting a document a rod 29, Fig. 1, connected with the control member 23 turns a pivoted spring latch 65, Figs. 2 and 5, the nose 66 of which is retaining the upper end of a rocker arm 50. The lower end of this arm carries rollers 48, 49, Fig. 6, which are in engagement with cams 46, 47 at different radial distances, on a disc 41 integral with a clutch disc 16. The arm 50 rocks on a spherical socket 51 on a fixed bolt 52 secured to the framework 56, the outward movement of the arm being limited by a stud 61 on a second mounting bolt 60. When the arm 50 is released, the spring 42 on the clutch shaft moves the clutch disc 16 into driving connection with the main drive wheel 5. During the rotation, the lower end of the arm 50 is moved inwards against the flat surface of the disc 41 by the spring 62 on the bolt 60, and the arm is relocked by the latch arm 65. When the cams 47, 48 again engage the rollers 48, 49 the clutch disc is retracted. During the rotation of the cam disc, the crank 13 on the pin 15 is first operated to feed the documents into position. The document is fed by an endless belt 7 extending over rollers 8, 9 and held against the belt by fine wires 17 fixed at their ends 17a and passing over coacting rollers 18, 19. The feed roller 9 is driven by a one-way clutch 21, and a reciprocated segment 11 connected to the crank 13. The camera apparatus (including a film-feed mechanism and shutter) is synchronously operated by a rocker arm 81 actuated by a crank 80 on a wheel 58 driven from a gear 40 on the clutch shaft. The ratio of this gearing may be 1 to 2 whereby two documents may be inserted into the machine before the camera is operated.

Title: Improvements relating to vapour electric rectifying apparatus
IPC: H02M7/15
Filed: 1924-11-19
Abstract: 246,943. Rowbotham, J. L., and Hewittic Electric Co., Ltd. Nov. 19, 1924. Vapour apparatus, arrangements of.-In vapour electric rectifying apparatus comprising a group of rectifiers arranged to work in parallel, automatic means are provided for bringing additional units into operation in succession as the direct current load increases or in the event of failure of one or more of the operative rectifiers, and for cutting out the units in succession as the load decreases. In the arrangement shown the trausformers 7, 8, 9 feeding three rectifier units comprising pairs of rectifiers 1 - - 6 are adapted to be connected to the alternating current bus-bars 10 by switches 11, 12, 13 provided with closing coils 24 and trip coils 25. The apparatus is started by closure of a switch 30, which may be time controlled, thus completing the circuit of a coil 31 connected to direct current bus-bars 23. This causes a resistance 34, normally short circuited at the contacts 33, to be introduced into the circuit of a coil 35, normally holding open a time lag switch 37, which now closes to complete the circuit of a coil 45 which in turn energizes the closing coil 24 of the switch 11 by closing the contacts 47. The removal of the short circuit from the resistance 34 also de-energizes a coil 48 which causes a switch 50 to open and introduce a resistance 51 into the circuit of the winding of a time lag switch 52 adapted to bring into operation the rectifiers 5, 6. When, however, the rectifiers 1, 2 have been rendered operative, the circuit of relays 29 controlled by coils 28 is completed thus restoring the short circuit on the resistance 34 thereby de-energizing the winding 24 and also arresting the operation of the time lag switches 52, 56. The rectifiers now supply current to the busbars 15 which are adapted to be connected to the main direct current bus-bars through a circuitbreaker 22. If, however, the rectifiers 1, 2 fail to become properly operative, the circuit of the relays 29 remains open and the time lag switch 52 is permitted to close to bring into operation the rectifiers 3, 4. Also in the event of the load exceeding the capacity of the rectifiers 1, 2, the coils 16 open the contacts 59 thus removing the short circuit on the resistance 51 and causing rectifiers 3, 4 to be brought into operation. Similarly, if the load exceeds the capacity of the rectifiers 1 - - 4 the short circuit on the resistance 55 is removed by relays 60, and mectifiers 5, 6 are brought into operation. The means for cutting out the units in succession as the load decreases comprises relays 20, 18 adapted to break, at the appropriate load values, the circuits of holding off coils of time lag switches 63, 65 which are adapted to complete the circuits of the trip coils 25 of the transformer switches 13, 12.

Title: Apparatus for measuring viscosity and other fluid properties
Inventor: BROOKFIELD DONALD WINTERS
IPC: G01N11/14
Filed: 1953-10-09
Abstract: 733,541. Electric viscometers. BRISTOL CO. Oct. 9, 1953, No. 27810/53. Class 40 (1). Apparatus for measuring the viscosity of a liquid comprises a motor driving a contact member directly, and a rotor immersed in the liquid through a spring coupling, so that the rotor lags behind the contact member by an amount proportional to the viscosity, the angle of lag being measured by the time delay between the coaction of the contact member and a slower moving contact member, and the coaction of a vane associated with the second contact member and a coil associated with the rotor, and indicated by the oscillation duration of a circuit influenced in opposite sense by these two phenomena. As shown, the liquid to be tested is contained in a cup 12 continuously fed by a pipe 13, the overflow being removed by a pipe 14 attached to an overflow container 11. Supported in the cup 12 is a rotor 36 driven by a constant speed motor 19 through a shaft 20, and coupled thereto by a spiral spring 41 whose inner end is attached to the shaft, and whose outer end is attached to a bracket 30 carrying a divided coil 32 and driving the rotor 36 through a shaft 35. Shaft 20 also carries a bracket 25 with an insulated contact member 27, and drives through gearing 46, 47, 48 an arm 43 carrying a second contact member 45 to co-operate with contact 27, and a vane 44 which can pass between the portions of the divided coil 32. Contact 27 is connected to a slip-ring 51 on shaft 20, and contact 45 is connected via the coil 32 and spring 41 to a slip-ring 52. When contacts 27, 45 are closed, power from a source 79 is supplied to a valve 60 which oscillates when the vane 44 is located between the two parts of coil 32. The anode current is sufficient to energize a relay 75 when the valve is not oscillating, whereupon a holding circuit at 76 is made, and contacts 77 cause energization of a meter 85, until the vane 44 moves between the parts of coil 32, valve 60 oscillates, and the anode current falls to release relay 75. In one embodiment the motor 19 drives the shaft 20 at 30 r.p.m. Thus the contact 27 and coil 32 rotate at this speed, the coil lagging by an amount proportional to the viscosity drag of the liquid on the rotor 36. The gearing 46, 47, 48 is such that the arm 43 rotates at 18 r.p.m. Thus twelve times per minute contacts 27, 45 close, followed by vane 44 passing between the parts of coil 32, the time interval between these occurrences being proportional to the viscosity and indicated by the meter 85 which shows the duration of the recurring periods of energization.
