Title: Improvements in or relating to brake control mechanisms
Inventor: KRAUSE HERBERT
IPC: G05G7/02
Filed: 1958-10-08
Abstract: 833,392. Brake pedal mechanism. CHICAGO FORGING & MANUFACTURING CO Oct. 8, 1958, No. 32110/58. Class 103 (1). A brake control mechanism, particularly for road vehicles, comprises a control lever 7 having a curved surface which is arranged concentrically to the pivotal mounting of the lever and surrounds a cam or clutch member 19 so that one or more rotatable elements 30 located between the curved surface and the cam can be urged into close frictional engagement with the curved surface on movement of the lever towards its brake-applying position, as shown in Fig. 2. From such position, the arm 7 is prevented from rotation in a clockwise direction, towards a non- braking condition, by the frictional pressure contact between the rollers 30, the housing 16 and the surfaces 21, 22 and 23. Such clockwise rotation causes the rollers 30 to bind together against the housing 16 and the camming surfaces. The brake is releasable from its locked breaking position by slight upward movement of the handle 49 on the lever 43, such movement being effective to rotate member 40 and the fingers 32 in a counterclockwise direction so as to move the rollers 30 towards the centre of the camming surfaces 21, 22 and 23 and therefore out of binding frictional contact with housing 16. Spring means connected to cable 11 are thus permitted to rotate the brake arm 7 in a clockwise direction towards the " brake off " position.

The 4 - carbamoyl - 5 - (N1 - aroyl - S-methylisothiocarbanoyl) amino - 1 - (21,31 - o - isopropylidene - b  - D - ribofuranosyl) imidazole reactants may be prepared by the following sequence of reactions (1) preparation of 5-amino - 4 - carbamoyl - 1 - (21,31 - o - isopropylidene - b  - D - ribofuranosyl) imidazole by reacting 5 - amino - 4 - carbamoyl - 1 - ribofuranosyl-imidazole with acetone in the presence of a Lewis acid or by amination of methyl-5-amino - 1 - (21,31 - o - isopropylidene - b  - D-ribofuranosyl) imidazole - 4 - carboxylate; (2) heating the imidazole product of (1) with an aroyl isothiocyanate of formula Ar.CO.NCS to form the corresponding 4-carbamoyl-5-(N1-aroyl-thiocarbamoyl - amino - 1 - (21,31 - o - isopropylidene - amino - 1 - (21,31 - o - isopropylidene - b  - D - ribofuranosyl) imidazole; and (3) methylating the imidazole product of (2).
Patent GB-1200702-A (GB)
Title: Circuit interrupter having dual-bore arc extinguishing means
IPC: H01H85/38
Filed: 1968-07-05
Abstract: 1,200,702. Fusible cut-outs. WESTING- HOUSE ELECTRIC CORP. 5 July, 1968 [24 Aug., 1967], No. 32229/68. Heading H2G. A circuit interrupter 100 comprises a tubular insulating casing 32, annular blocks of arc extinguishing material 122, 124, 126, 128, e.g. of boric acid housed in casing 108, each having aligned large and small bores 130, 192 with a conducting rod 83, 182 disposed in each, each block having in its face contracting other blocks a recess (126b in Fig. 3, not shown), extending around and spaced from the small bore 192, each recess having an opening to the periphery of the block, a bonding material, e.g. epoxy resin, filling adjacent pairs of said recesses. The fuse unit 100 is supported by insulators 272 and 282 with contact 250 latching the upper terminal 34 and contact 260 pivotably supporting lower terminal 36. Conductive elements 160, 162 and 194 connect the rods 83 and 182 to terminal means 150. The fusible element 160 is of lowest resistance of the three elements and under overload conditions fuses first, followed by strain member 162. When strain member 162 fuses the conductive rods 83 and 182 joined by pin 184 at their top ends are moved upwards under the influence of spring means 76, stretching the helically coiled wire 194 until it either fuses as it is carrying the full current or else is mechanically broken. Arcing will take place at this breakage and will usually occur between the end of the rod 182 and the arcing terminal 158, which is coated with a thin layer of insulating enamel. When interrupting low currents, e.g. less than 1000 amps the arc will be extinguished by gases produced in the arc extinguishing material of the small bore 192, but with larger currents the arc may then restrike in the main bore 130 from the retreating end of rod 83, where it is normally extinguished. The epoxy filled recesses around the small bore prevents ionized gases from travelling between bores. With still higher currents the temperature and pressure in the box may rise to a dangerous level in which case the thin walls 126A and 128A between C-shaped recess 129 and the bore 130 will rupture to reduce the pressure. The conductive rod 83 is connected to the upper terminal 36 by flexible cables 82 and conductive member 60. When the spring collapses after fusion of the strain member, the member 74 to which the upper end of the spring is secured slides over the member 60 under the reaction of the spring and pin 56 which is secured to the spring moves in slot 62 of member 60 and tripping member 52 integral with the pin 56 moves through the hole 46 in cap 44. The tripping member 52 detaches the latching means 250 and fuse unit 100 drops out of contact with the upper contact pivoting on the lower terminal means 260. Pivotable means 274 is provided on the upper terminal 34 to allow opening and closing of the connection through the fuse unit using a hook stick.

Title: Improvements in or relating to door-closing apparatus
IPC: B60J5/00
Filed: 1933-11-20
Abstract: 418,870. Door-operating appliances ; door stops ; fastenings. BOSCH AKT.- GES., R., 4, Militõrstrasse, Stuttgart, Germany. Nov. 20, 1933, No. 32232. Convention date, Nov. 18, 1932. [Classes 44 and 65 (i).] The closing of a swinging door is completed by a spring which is stressed during the opening or early closing movement of the door, the arrangement giving a large leverage for easy stressing of the spring while the spring, in closing the door, acts directly on a short lever the device may be arranged on the door or door frame. In the form shown, the spring 27 is held between an abutment on the door and one arm of a crank 21 pivoted on the door near its free edge and connected to the hinge post by a cord 23 passing over a pulley 24 on the door ; on opening the door, therefore, the spring is compressed by the action of the cord and is held compressed by a spring catch 31 engaging the hub of the crank 21 as shown. When the door approaches the closed position, another arm of the crank 21 passes a projection 28 on the door post, which then engages a pin 33 to lift the catch 31 out of engagement with the crank 21 ; the spring 27 is thus released, and forces the crank to bear against the back of the projection 28 and thus close the door. The door itself acts as a lever in stressing the spring, but the crank 21 is the closing lever. The cord may be replaced by a rod or hydraulic transmission. The crank 21 may be released from the projection 28, to open the door, by a tail on the pivoted latch 34, Fig. 3, which fastens the door closed. The closing of the door is cushioned by a plunger in a cylinder 38, which is pressed in by the door against the pressure of a spring and the resistance of enclosed air leaking out through a small aperture in the cylinder head.
