IPC: D06C3/04
Filed: 1954-02-08
Abstract: 739,931. Finishing fabrics. WINDHORST, A. MEIER-, [trading as MEIER-WINDHORST KOMM.-GES. DR. ING. A.]. Feb. 8, 1954 [Feb. 7, 1953], No. 3651/54. Class 42 (1). A method of fixing fabric webs with overfeed on to the pins of tenter frames with pin block chains and cylindrical brushes consists in blowing compressed air against the brim or edge of the fabric to press it tightly against the brush at a point directly preceding the place where the brush presses the web with overfeed on to the pins of the pin blocks of the tenter. In apparatus for carrying out this method a hollow guide member 5 is arranged adjacent the point of engagement of the brush 2 with the pin blocks 1 and has on its side facing the brush 2 apertures through which compressed air is blown in the direction of the arrows, thereby forcing the web 3 away from the surface of the guide member 5 and against the periphery of the brush 2. In a second embodiment, the guide member is arranged much closer to the periphery of the brush so that an air cushion is formed between the guide member and the brush. Preferably, the apertures in the guide member 5 are in the form of longitudinal slots in the direction of travel of the web so as to prevent them becoming clogged by dust or fluff.

Title: Improvements in or relating to cameras
Inventor: NOACK ROLF
IPC: G03B19/12
Filed: 1966-01-28
Abstract: 1,086,073. Reflex cameras with roller blind shutters. PENTAGON DRESDEN KAMERA UND KINOWERKE VEB. Jan. 28, 1966, No. 3926/66. Heading G2A. A reflex camera with roller blind shutter is provided with mechanism to delay the shutter actuation until the objective diaphragm has closed to its preset value, and the mirror has pivoted to its picture taking position. The mechanism (shown cocked) comprises two segment levers 14, 16, the lever 14 of which is connected, via a slider 6 and pin and slot connection 11, 12 with a cocking wheel 1. The cocking operation causes the film to be wound on, mechanism for retarding the running down of the second blind to be cocked by means of an arm 9 of the slider 6, a lever 32 indicating the uncocked state of the camera to be pivoted out of the camera viewfinder, and a spring 7 to be tensioned. To effect an exposure, a release lever is operated so that its nose 10 liberates the slider 6 to move to the left (as shown) under action of the spring 7. This movement is effected evenly by means of the lever 14, the clockwise running off of which is retarded by gearing 18-21. The lever 14 carries with it, by means of pawl 15 and nose 30, the lever 16, the movement of which shifts a diaphragm plunger 24 against a compression spring 33 to set the diaphragm to its pre-selected value. Clockwise movement of the levers brings the mirror into the picture taking position by means of a pin and slot connection 28, 29, and also tensions a spring 27 and pivots the lever 32 back into the viewfinder. When the slider 6 reaches its rest position, the first blind and the mechanism retarding the second blind are liberated by the arm 9. A slider 17 lying in the running off path of the second blind, is shifted in the direction of the arrow after the exposure has been made, thereby moving the pawl 15 to allow the lever 16 to be pivoted anticlockwise by the spring 27, thereby returning the mirror to the observation position and the diaphragm to its fully open position.

IPC: H02J7/18
Filed: 1928-02-13
Abstract: 317,302. Sykes, B. Feb. 13, 1928. Exciting; dynamos, regulating.-A variable-speed generator A supplying a load L and charging a battery M is provided with a shunt field winding B across the brushes or across the lines from the generator A to the load L, with a series field winding C for load compensation, with a reverse-current cutout E preventing back discharge of the battery, and with a reverse field winding D connected in series with the battery M across the brushes or the lines without the intervention of any additional switches. The winding D is always in action when the cut-out E is closed. When the generator is supplying the load, the winding D does not carry load current but the charging current to the battery causes a demagnetizing effect on the field. Constant voltage and charging current at varying speeds are thus obtained. The coils C, D may be of low resistance, and a battery having a charging rate much below the full generator output may be used. To prevent overcharging, a voltage relay F across the lines may close to reduce the charging current, or cause the battery to discharge, when the voltage rises, the relay contacts G breaking the circuit of the field B as shown or connecting a bye-pass load circuit, such as a resistance, across the battery.
