Title: Improvements in tensioning means for endless conveyors
IPC: B65G23/44
Filed: 1957-03-29
Abstract: 821,970. Endless conveyer tensioning apparatus. STAHLWERKE BRUNINGHAUS G.m.b.H. March 29, 1957 [April 26, 1956], No. 10421/57. Addition to 793,229. Class 78(1). In endless conveyer tensioning apparatus as disclosed in the parent Specification the hydraulic pressure generating means is operated by a servomotor mounted on it to form a single assembly. The servomotor 1 is of the kind in which a rotating linkage operates by centrifugal force to apply thrust to a pin 1a, the linkage being rotated by an electric motor which is switched on and off at regular intervals. The resulting reciprocating movement of the pin la is transmitted by a rocking lever 2 to a piston 5 operating in a cylinder 6 to pump oil from a chamber 7 via a non-return valve 8 into a pressure chamber 9. A piston 10 acted on by a spring 11 in the chamber 9 is fixed to a lever 16 connected to a sliding support 17 for the tensioning pulley 18a. When the desired tension has been reached a contact manometer communicating with the chamber 9 opens the circuit for the servomotor and switches on the conveyer driving motor. If the tension should become excessive an electromagnetic valve 12 is opened to relieve pressure in the chamber 9 so that the conveyer driving motor is switched off.

Title: Improvements in or relating to synthetic resin adhesives
IPC: C09J161/24
Filed: 1943-06-28
Abstract: An adhesive, e.g. for gap-joints, comprises an aqueous cold-setting urea-formaldehyde resin, a comminuted cellulosic filler, and an aliphatic or alicyclic alcohol, aldehyde, or ketone which is partially soluble in water (preferably 1-20 per cent at 20 DEG  C.) and completely miscible with ethyl alcohol at ordinary temperatures. Fillers specified are wood flour, disintegrated wood pulp or powdered cotton.  Preferably 5-15 per cent filler, based on the weight of a resin solution containing 70 per cent solids, is mixed first with once to twice its weight of alcohol, aldehyde, or ketone.  If the latter body tends to separate from the adhesive a substance miscible with it and with water, e.g. ethyl alcohol, is added, and up to 20 per cent starch may be added to thicken.  Hardening agents are added to set, e.g. ammonium chloride or thiocyanate and formic acid.  In examples: (1) wood flour is impregnated with butyl alcohol and mixed with a resin solution known as Aerolite 300.  Before use 5 per cent ammonium thiocyate is added; (2) wood pulp. butyl alcohol, ethyl alcohol, cassava starch, and Aerolite 300 are mixed and hardened with ammonium chloride or thiocyanate; (3) mahogany wood flour, isoamyl alcohol, ethyl alcohol, cassava starch and Aerolite 300 are mixed and hardened as in (1) and (2); (4) the isoamyl alcohol of (3) is replaced by cyclohexanol, butyraldehyde, crotonaldehyde, diethylketone or cyclohexanone; (5) the ethyl alcohol of (3) is replaced by methyl alcohol, acetone, glycol monoethyl ether, diacetone alcohol, or dioxane; (6) the powder obtained by spray-drying Aerolite 300 is mixed with wood flour, butyl alcohol, ethyl alcohol, and water.  Aerolite 300 is obtained by boiling 1 mol. urea with 1.95-2.05 mols. 37 per cent formaldehyde under mildly acid conditions, until on neutralisation and evaporation to 70 per cent solids content, the solution has a viscosity of 100 poises at 20 DEG C.

Title: Photographic camera
IPC: G03B17/24
Filed: 1968-03-06
Abstract: 1,211,567. Cameras. R.D. PRODUCTS Inc. March 6, 1968 [July 17, 1967], No.10898/68. Headings G2A and G2C. A camera has means for removably housing a data-carrying transparency which can be brought into direct contact with the film, so that during exposure the said data is photographed simultaneously with the external subject. As shown in Fig. 3, the subject viewed by the objective lens 18 is reflected by a mirror 20 through an aperture 25 in the camera housing on to the film plane. The film F is contained in a detachable magazine 45, and is wound from a supply spool 54 over a metering roller 60, across the aperture 25 on to a takeup spool 64. The transparency 33 Fig.6, containing data such as would appear on an identity or credit card, is placed in a slide 30 comprising a base plate 34 and hinged cover 35, and having a handle 32 at one end. The slide can be pushed into a slot between the camera and the film magazine, until openings 37, 38 of the slide are aligned with the aperture 25. Two fingers 82 on shafts 80 can be pivoted by a solenoid-actuated linkage so that they bear against the transparency itself and hold it directly against the film F. The camera shutter is a single blade 110 pivoting on a shaft 105. This is actuated by a rotary solenoid 104, and swings open to make the exposure. As it reaches its fully open position, it trips an arm 112 of a switch 114, which fires a flash illumination. Thus both the picture of a person and identifying data can be photographed at the same time. The metering roller 60 now rotates to wind on the film one frame. The sequence of operations is automatic, and controlled by the circuit of Fig. 7 (not shown).

Abstract: 1,118,854. Photo-electric diffractometer; recording apparatus. SOC. NATIONALE DES PETROLES D'AQUATAINE. March 14, 1966 [March 19, 1965], No. 11080/66. Headings G1A and G1J. Diffractometer apparatus especially suitable for crystallographic investigation includes a graphic recorder 8 whose stylus is controlled to move along the X-axis in accordance with the angular position of the goniometer 2 on which the sample 3 is mounted and along the Y-axis in response to the output of the detector of diffracted radiation from the sample. The recording paper 12 is advanced step by step and at each step a fresh trace is drawn. The temperature of the sample, which can be enclosed in an oven (not shown), is changed for each trace drawn, so that a series of graphs indicating crystallographic changes of the sample with temperature are obtained Fig. 2, (not shown). The apparatus includes a fixed source 4 and movable detector 5. The goniometer is rotated by means of a motor 28. The angle moved through by the goniometer is picked up by a friction disc 15 coupled through gearing to control the contact of a helical potentiometer such that a varying output signal, representing the angular displacement of the goniometer, is applied to the recorder to alter the stylus position across the chart (X-axis). The intensity of the diffracted radiation from the sample is sensed by detector 5 and the resultant signal applied to an integrator 10 whose output controls the Y displacement of the stylus 9 by movements of a bridge 22. The end of forward travel of the goniometer occurs when an arm 31 mounted contacts a switch 14, which results in the motor 28 being reversed to drive the goniometer back to the start position (this being accomplished at a higher speed than the forward speed), the stylus being raised from the paper and returned to its zero position, and a motor 25 being actuated to advance the paper in the recorder. The temperature of the sample is also changed. The highspeed reverse travel of the goniometer is halted by an arm 27 contacting switch 13, when the drawing of a fresh trace can be commenced.

Abstract: 181,549. Cholerton, G. April 16, 1921. Carriages.-The bobbin carriages A are provided with discs D pivoted at G in place of the usual verge while the spring H has a shoe J at the free end to fit over the side plates of the bobbin C. The discs D are located in recesses closed by covers F. When the thread is partly worked off the bobbin, the side plates close in and grip the discs which then act as anti-friction devices. The recess of the shoe J may be so proportioned that, when the bobbin is full, the shoe J does not fit so close down on the side plates as when the bobbin is less full of thread. The result is to relieve the spring H as the bobbin empties and to compensate in part for the increase in tension due to the pull on the thread approaching the centre of the bobbin.
