Title: Process for the production of resinous condensation products from amines of the aromatic series
IPC: C08G12/08
Filed: 1926-03-15
Abstract: 274,155. Mond, A. L., (I.G. Farbenindustrie Akt:-Ges.). March 15, 1926. Formaldehyde-amine condensation products are obtained by the action of formaldehyde on aromatic amines in the presence of an amount of amino salt -not -substantially exceeding 10 per cent of the amount of amine. employed, the condensation being effected in aqueous solutions of alcohols in which the amines are soluble. The products are resins, the softening points and other physical properties of which depend on the amount of amino salt present during the condensation. Volatile admixtures may be removed by heating the products in vacuo. The condensation may be carried out in closed vessels above the boiling point of the aqueous-alcoholic phase, and resins of higher softening point may be obtained by increasing the proportion of formaldehyde above the molecular ratio, e.g. 1“ or 1¢ molecular proportions of formaldehyde may be employed for each molecular proportion of amine. The amino salt may be that formed from the formic acid present in commercial formaldehyde, or it may be present as hydrochloride or other salt. Examples are given of resins obtained from aniline and o-toluidine with varying amounts of amino salt. The products are resistant to alkali and are suitable, among other purposes, for use as resists in batik dyeing and printing, particularly when working with dyes in an alkaline medium. They can be removed from the fabric by organic solvents or weak acids, or by treatment with hot water after the printing operation.

Abstract: 664.060. Vulcanizing presses for tyres. SVIT, NARODNI PODNIK. March 16,1949 [March 16, 1948], No. 7162/49. Class 87(ii) A vulcanizing press of the watch case type, Fig. 2, has upper and intermediate movable platens 13, 9, respectively which co-operate together and with a fixed platen 1 to vulcanize simultaneously two rubber tyres positioned in the press in superposed relationship, and is characterized by the fact that each movable platen is tilted up and down by its own separate electric motor. The platen 9 is moved by means of links 8, and cranks 7 fastened on a shaft 6 which is rotated by a motor 3 through a worm and wheel gear 4, 5. The motor is started by a push button 2. A similar crank arrangement driven by motor 3<SP>1</SP> started by push button 2<SP>1</SP> moves the platen 13. In operation, one tyre is positioned on the platen 1, the platen 9 then being lowered upon it, and the second tyre is similarly positioned between the platens 9, 13. The tyres are provided with special inner tubes which are connected to a compressed air line or a hot water supply, and an electromagnetic valve known per se, (not shown) is operated when the press is closed to inflate the inner tubes with air or hot water. After the vulcanizing period which is determined by a conventional timing device (not shown), the timer operates the valve to discharge the inner tubes and then puts the motor 3' into operation to open the press. The upper tyre is then removed and the motor 3 operated by the push button 2 so that the other tyre may be removed. Cams 10, 10<SP>1</SP> and 14, 14<SP>1</SP> on the crank driving shafts operate switches 12, 12<SP>1</SP>, and 16, 16<SP>1</SP>, respectively to control the electric motors so that the platen movements take place in timed sequence.

Title: Improvements in or relating to pneumatic conveyor plant
IPC: B65G53/66
Filed: 1950-03-23
Abstract: 722,992. Pneumatic conveyers. MIAG VERTRIEBSGES. March 23, 1950 [Oct. 1, 1948], No. 7260/50. Class 78 (1). Flap 3 controls the air-and-material flow along duct 2 into material discharge device 1 and is operated in accordance with the pressure in said duct, the pressure registering on indicator 6 through pipes 8. When no material is being carried the increase of pressure causes indicator 6 to make a circuit 7 which operates electromagnetic mechanism 5 to close weighted flap 3 wholly or partially. There is also added a common indicator 21 connected by pipe 20 to each duct 2 and indicating the combined pressure of all the ducts. When this combined pressure is low (i.e. all the ducts are working) the indicator 21 operates electric circuit 26 to cause switches 22 each to cut-out its mechanism 5 so that flaps 3 all take the non-throttling position. If however one duct ceases to work then indicator 21 operates all the switches 22 to alert each its respective mechanism 5 so that the corresponding flap is able to operate to throttle the non-working duct. In a second embodiment, material-carrying air passes through ducts into separate chambers and, through ports governed by flaps into a common material discharge device. Operation of the flaps is effected by pistons through a lever system. The pistons are connected by pipes respectively to said separate chambers so that if the pressure in one chamber increases the pistons move to the right and close one flap and open the other flap. This embodiment also works in dependence upon the combined pressure.

Title: Improved Disc Brake.
Inventor: HAYES EDWARD JAMES
IPC: F16D55/22
Filed: 1967-02-15
Abstract: 1,155,233. Disc brakes. KELSEY-HAYES CO. 15 Feb., 1967 [28 Feb., 1966], No. 7298/67. Heading F2E. A disc brake includes brake pads 69, 89 movable transversely to opposite friction surfaces of a disc 29, rotatable with a wheel 11 to be braked, each brake pad comprising a backing plate 67, 87 having a brake lining 69, 89 secured thereto adapted to be frictionally engageable with the disc surfaces when the brake is applied by hydraulic actuators 47, 49, the brake pads being carried in a non-rotatable housing 33, a leg 109, 111, 113, 115 being formed integrally with the plates 67, 87 and hinged to the backing plates 67, 87 at one end thereof and operable to transmit braking torque from the plates to the housing in one direction of rotation of the disc, the leg being pivotable with respect to the disc during such torque transmission to permit slight circumferential movement of the brake pad to increase the contact pressure between the brake pad and the disc. Each hinged leg is formed by an intersecting longitudinal slot 116, 117 and a transverse notch 119, 121 in the plate (as shown in Fig. 3). When the brake disc is rotating in a clockwise direction the brake pad 53 is applied and frictional contact between the pad and the disc surface 57 exerts a torque on the pad causing the leg 113 to press tightly against the non-rotatable housing surface 123. The leg 113 is caused to pivot or bend slightly away from the disc 29 about an axis adjacent and behind the notch 119 which serves to move the brake pad more tightly into engagement with the disc surface to increase the total braking effect realized. If the disc 29 is rotated in a counterclockwise direction the leg 115 is pressed into tighter engagement with the non-rotatable housing surface 125 to cause the leg 115 to bend or hinge about an axis adjacent and behind the notch 121 to increase the total braking effect on the brake pad 53. As shown in Fig. 1 generally rectangular cross-sectional seals 71, 73 are carried within the bores 59, 61 sealingly to engage the piston 63, 65 of the brake-actuating mechanism and these seals become twisted or distorted when the pistons move towards the brake disc 29 so that upon release of the fluid pressure the seals 71, 73 return the pistons away from the brake disc 29.

In a method of assembling a torsional vibration damper in which a disc 10, adapted to be bolted, e.g. to an engine crank-shaft, has an annular cavity defined by side walls 12, 13 and a radially-extending base wall 14 and at least one annular elastic member introduced into the cavity, with an annular inertia member 18 the depth of penetration of the inertia member 18 into the groove is determined by a series of circumferentially-spaced, hollow screw caps 31 which are inserted into apertures 22 in the inertia member prior to its placement in the annular cavity. The screw caps 31 protrude a predetermined amount from the interior face of the inertia member and bottom against the base 14 of the cavity when the inertia member is inserted at the correct depth in the cavity. After the inertia member has been positioned the cap screws 31 are removed and a measured quantity of viscous fluid is introduced into the chamber 26 through the apertures 22 which are finally plugged by the insertion of closure members 23. The length of the cap screws 23 defines the pressure of the fluid in the chamber 26. As shown, two elastic members 16, 17 whose thicknesses may differ, are interposed between the inertia member 18 and the inner and outer walls 12, 13 respectively of the cavity. Specification 874,441 is referred to.

Abstract: 512,634. Endless-belt conveyers. JORGENSEN, M. VOGEL-. March 9. 1938, No. 7383. [Class 78 (i)] [Also in Groups XVIII, XXXV and XXXVIII] In apparatus for feeding granular material at a constant rate, an endless belt is arranged to extract material in a layer that is substantially constant in thickness, and means are provided for controlling its speed in accordance with the weight of material on it. The belt 2, Fig. 1, is mounted on a framework which is supported by pivots 29 and carries a driving motor 11 and an adjustable counterweight 19. The pivots 29 are connected to a contact drum 40, Fig. 3. The latter rocks as the conveyer moves up and down, and closes the circuits of one or more solenoids 44, thereby short circuiting a corresponding number of resistances 39 in the field circuit of the motor 11. The field circuit is thus varied to regulate the speed of the motor and maintain the flow of material substantially constant. The belt is given the desired initial slope by adjusting the counterweight 19. The framework is composed of side members 25, 26 and 27, longitudinal members 14, a platform 18 and junction plates 22, 23, 24 and 28. The upper run of the belt is supported by planks 17 which are fixed to supports 16 carried by transverse girders 15. The belt forms the bottom of a trough 31.
