Filed: 1975-02-21
Abstract: 1456346 Cameras PENTACON DRESDEN KAMERA-UND KINOWERKE VEB 21 Feb 1975 [22 Feb 1974] 7426/75 Heading G2A A camera has a first control circuit (not shown) arranged to produce an output dependant on scene brightness and exposure factors set, at least one indicator light 1, 2 controlled by the first circuit (in Fig. 1 via resistors 5, 6) and a second control circuit 7 to 16 having a photo-sensitive element 16 exposed to scene illumination or to the image of a scene in the camera view-finder, the second circuit being coupled to the or each light 1, 2 so that the brightness of the latter depends on the brightness of the scene or view-finder image and thus remains clearly visible. In Fig. 1 lamps or L.E.D.s 1, 2 are connected via transistors 3, 4 and resistors 5, 6 to the first control circuit whose output depends on diaphragm aperture, exposure time and film speed settings and on scene brightness. If exposure is incorrectly set lights 1 and 2 are unequal in brightness or one of them illuminates steadily and the other flashes. The brightness of lights 1 and 2 is also controlled by a multi-vibrator 9 to 16 which includes a photo-conductive element 16 preferably exposed to the view-finder image. In Fig. 2 (not shown) transistors (18, 19) are connected in series with lights 1 and 2 respectively and a photo-conductive element (17) is connected to the bases of both transistors (18, 19).

IPC: B01J8/44
Filed: 1953-03-20
Abstract: <PICT:0741613/III/1> <PICT:0741613/III/2> Withdrawal of solids from a gravitating bed type of solids/gases contacting apparatus is effected by providing at the lower part of the apparatus a partition plate containing perforations through which the solids pass, arranged preferably in concentric circles, over the cross-section of the apparatus, each perforation being associated with a conduit, which conduits discharge into separate open bottom compartments arranged on a common circle from which the solids pass to a common discharge pipe.  As shown in Fig. 1, the perforations in the horizontal plate across the bottom of the chamber X are associated with conduits 60, 61, having their inlets arranged on concentric circles.  The conduits discharge into individual open bottom compartments formed by sub-dividing with radial fins 64 (see also Fig. 2) the annular space formed between the conical wall 37 and a ring 65.  From these compartments the solids gravitate to a common discharge pipe 38.

Title: Improvements relating to pencils
IPC: B43K21/08
Filed: 1929-03-09
Abstract: 328,084. Harley, F., Myers, L., and Jacobs, E. March 9, 1929. Pencil holders. - Relates to screw-propelling pencil holders of the kind in which the two main parts of the holder are separated by the action of the propelling- mechanism when the lead is exhausted. The lead b is carried in a socket c actuated by propelling-mechanism in a tubular part d, the mechanism being under the control of an operating-head g rotatable relatively to the part d. The part d is held against axial or rotational movement in the casing a by the engagement of a swelling h. on the part d with a corresponding recess in the end of the outer casing a, one of the parts a, d being rendered resilient by slots. When the lead is exhausted the socket c abuts against the internal tapered surface of the front end of the case a. and further rotation of the head g causes the part d to be pushed rearwardly out of the case. Specification 196,397 is referred to. According to the Provisional Specification, when the mechanism reaches the end of its movement in either direction, further rotation of the operating head causes the inner part to rotate and to disengage a projection thereon from a recess or bayonet slot in the outer part, axial separation being effected by a spring.

[Also in Group XXII] A screw press with a friction-roller drive of the flywheel is characterised in that one or more friction rollers driven by a reversible electric motor is or are constantly pressed to the flywheel by elastic means. The tup 2 is operated by a screw 4 which engages a nut 3 on the tup. A collar 5 on the spindle rests against the frame and keyed to the end 6 of the spindle is a cupped flywheel 7 having an inside grooved friction surface engaging a friction roller 8 driven by a motor 10, mounted on members 12 and 12a of the frame and pressed outwardly by springs 13 and 13a adjusted by nuts 14, 14a so that the roller is pressed against the flywheel. Brake blocks 9 and 9a also engage the flywheel and are controlled by linkages 15 and 15a, connected to spring-loaded pistons 17 and 17a operating in a fluid pressure cylinder 16. The brakes stop and hold the flywheel when the tup is in its top-most position and springs 19 and 19a hold the flywheel, in the absence of the pressure means, against automatic operation. In operation a piston valve 21, Fig. 4, is moved by a magnet 20 so that an air inlet 22 is opened to atmosphere whilst pressure means is applied to cylinder 16 through an outlet 23 so that the springs 19 and 19a are overcome and the brake blocks 9 and 9a released. The electric motor is controlled for left and right hand running by manual levers. Adjustable cams on the tup engaging contacts on the press frame provide for stroke adjustment. In an embodiment.two friction rollers 27 and 27a, Fig. 6, are connected to a bearing bracket 24 through levers 25, 25a and links 26, 26a so that they engage the flywheel and also an intermediate wheel 8<SP>1</SP> on the motor shaft. The wheel 8<SP>1</SP> may be a toothed wheel engaging toothed wheels on the shafts of the rollers 27, 27a. Springs 28, 28a urge the rollers into contact with the flywheel.

Title: Improvements in or relating to arylphosphono dithioic acid derivatives
IPC: C07F9/59
Filed: 1963-02-28
Abstract: The invention comprises aryl phosphono piperidino-dithioic acids and salts thereof.  The invention also comprises: (a) a method of preparing a piperidinium aryl phosphonopiperidino dithioate characterized by heating a dimeric aryl phosphonotrithioic acid anhydride with a stoichiometric excess of piperidine, removing the excess of piperidine and recovering the piperidinium aryl phosphinopiperidino-dithioate and (b) a method of preparing an aryl phosphonopiperidinodithioic acid which comprises acidifying with a dilute mineral acid an aqueous solution of piperidinium aryl phosphonopiperidinodithioate (prepared as above) to form a precipate of aryl phosphonopiperidinodithioic acid and removing the aqueous phase from said precipitate. The aryl group present in the products may be unsubstituted or may be substituted by a substituent which is resistant to the action of piperidine, e.g. fluorine, chlorine, bromine, iodine or a nitro, amino, trifluoromethyl or acyl, including aroyl group. In method (a) above the reaction is advantageously carried out by heating the mixture at a temperature up to the reflux temperature of the mixture, e.g. above 105 DEG C. or higher temperatures may be used under superatmospheric pressure. The piperidine may also be used in less than the stoichiometric amount but this results in a reduced yield. The piperidinium salt of phenyl phosphonopiperidino-dithioic acid may be reacted with a silver or lead salt, e.g. silver nitrate or lead acetate to form the silver and lead salts of phenyl phosphonopiperidino dithioic acid. Examples are given for the production of piperidinium phenyl phosphonopiperidinodithioate, phenyl phosphonopiperidino-dithioic acid and its lead and silver salts, piperidinium p-chloro phenyl phosphonopiperidinodithioate, and p-chloro phenyl phosphonopiperidinodithioic acid and its sodium salt. Several other aryl phosphonopiperidinodithioic acids and salts thereof are also specified. The products are useful as textile assistants, surface active agents and as antioxidants or corrosion inhibitors for antifreeze compositions, lubricating oils, plastics or rubber.
