Patent GB-464764-A (GB)
Title: Improvements in or relating to friction transmission mechanisms
IPC: F16H61/664
Filed: 1935-09-23
Abstract: 464,764. Friction gearing. ERBAN, R. Sept. 23, 1935, No. 26354. [Classes 80 (i) and 80 (ii)] A friction roller 115, Fig. 7, which works between oppositely-running races, not shown, is free to swing about an axis AA oblique to the plane of the roller. The axis cuts tangentplanes of the contacts of the roller with the races at points one on each race which lie each on the approach side of a plane containing the contact point and the roller axis. The object is to get stability of the roller, and the invention is a development of the arrangement described in Specification 283,934, [Class 80 (ii)], in which the axis of free swing is oblique to the race but not to the plane of the roller. Analytical diagrams are furnished. In the precessional variable-speed gear with toric discs shown in Fig. 1, 2 and 3, this oblique axis AA passes through the centre of the roller 15, which it does not do in the arrangement of Fig. 7. A ball 33 which supports each roller at its centre is supported on a lug 17 of a spider 16 through which spider passes loosely a shaft 12 carrying a toric race disc 11. The other race disc is loose and shown at 10, and the usual adhesion pressure generating device is not shown. Swivel mounted on each ball 33 is a bearing element 35 upon which the roller 15 rotates between shoulders 36. The inner shoulder 36 has a pin extension 41 which passes freely through a ball 14 which is pressed into an arcuate groove 45 upon the spider 16 by a cup 25 upon a control arm 24. There is an arm 24 for each roller 15, and these arms are rigid with a control hub 23 which is rocked about the shaft 12 by moving a ball end 30 to bring the axis AA to other positions such as A<1>A<1> and A2A2 where precession starts and continues until a change in the speed ratio has been completed. In a form shown in Figs. 4 and 6, the roller 215 is in a carrier 212 which rocks about trunnions 240. The obliquity of the axis DD about which the roller 215 is free to rock is obtained by an oblique cylindrical bearing surface between inner and outer bushes 222, 224 fast respectively to a through pivot pin 220 and to a bearing 216 on which the roller turns freely. When the direction of the power transmission reverses, the obliquity of the axis DD must be reversed, and this is provided for by allowing the pin 220 to turn freely through a limited angle with respect to the carrier by lost-motion means 221, 245.

Title: Improvements in or relating to Photographic Printing Apparatus
Inventor: JEHMLICH GERHARD
IPC: G01J1/42
Filed: 1966-06-14
Abstract: 1,155,482. Controlling contrast. PENTACON DRESDEN KAMERA-UND KINOWERKE, VEB. June 14, 1966, No.26382/66. Headings G2A and G2C. In a process for printing from a negative on to a photo-sensitive sheet, the contrast is assessed by scanning the illuminated negative by a photoelectric device which automatically determines and controls the main exposure and, if necessary, an auxiliary overall exposure. If the range of values of the contrast of the negative (log K N ) is less than the copying range of the photo-sensitive paper (KU p ), then no auxiliary exposure is necessary [Range I]. If log K N  is greater than the copying range KU p , then a maximum auxiliary exposure is required [Range III]. If the two are the same [Range II] the amount of the auxiliary exposure is determined automatically. The theoretical considerations involved are discussed, and Fig. 4 shows an arrangement in which they are applied to the contrast assessment of a film frame as illuminated by a lamp 2, the light transmitted being received by a photo-cell 4 via a scanning device 3, shown in more detail in Fig. 5. Between the illuminated negative frame 1 and the photo-cell 4 is an apertured partition 12, a pair of optical wedges 10, 10' having the same wedge angle and so disposed initially as to form a parallel plate, and a cylindrical lens 11. The wedges are rotated in the same direction at constant but different angular speeds. Thus the illuminated spot on lens 11 which is received by cell 4 is scanned spirally round a circular area. This is distorted to an elliptical area by the lens 11, so that the illuminated spot on the negative film frame 1 which is received by cell 4 is scanned spirally round an elliptical area. The output from the cell is fed to a series of computing circuits R 1 , R 2 , R 3  which carry out the necessary calculations and feed the resultant information in the form of controlling electrical pulses to the light sources 5 and 6 when the film negative 1 has moved on to the printing station. Lamp 5 effects the main exposure, projecting the image through an objective lens 7 on to the photosensitive paper 8, and the auxiliary overall exposure is effected by lamp 6, the light from which is reflected by a semi-transparent mirror 9 into the main light path.

The gaseous decomposition products obtained by testing substances in a thermoanalyis apparatus are progressively absorbed in a suitable liquid and continuously estimated by automatic titration, the titrating equipment being connected to a mathematical differentiator, e.g. a suitable induction circuit or a transformer, so that a simultaneous continuous record is obtained both of the titration reading with time and of the rate of change of the titration reading with time. These results may be time correlated with other conventionally obtained parameters such as temperature, weight change, rate of weight change and rate of change of entholpy to obtain a profile of the course of the thermal decomposition reaction.

IPC: H01H33/68
Filed: 1926-10-22
Abstract: 266,290. Magrini, L. Feb. 16, 1926, [Convention date]. Oil switches; cases. -The movable contacts of an oil break electric switch are carried by a plunger or piston which in its upward movement to break the circuit creates a vacuum within the casing approximately equal to the volume of are gases produced so that the pressure within the tank never rises above that of the atmosphere. As shown in the draw-- ings the contacts 5<1> which co-operate with fixed contacts 5 are mounted on a plunger 8. When the plunger is raised to interrupt the current in leads 6, 9 the arc gases follow the plunger in its upward movement to the upper part of the casing 1 and the lowering of the oil level within the casing places it in communication with the atmosphere through a pipe 4<1>. As the plunger descends for a subsequent switching operation the gases are forced out through the pipe 4<1> before the oil rises to seal the opening. Current is led to the movable contacts through spring plungers bearing on the sides of the plunger.
