Abstract: 867,050. Two-part couplings. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 13, 1959 [Oct. 29, 1958], No. 34695/58. Class 38 (1). A socket member for the reception of plug-in electromagnetic relays on one side and of wiring terminals on the other is secured to a support by means of an adapter plate which is spaced from the socket terminals and carries a pillar with means for releasably holding a, relay in position. As shown, a socket member 7, having four sets of sockets  8 1, 8<SP>2</SP>, 8<SP>3</SP>, 8<SP>4</SP> and locating sockets 10 for plug terminals 1 of relay coils R and bosses 5 respectively has depending lugs 25 forming abutments for an adapter plate 11 which has positioning slots 24 for socket lugs 23 and tapped holes 30 whereby it may be secured to a frame 12 by screws 29. The socket member 7 and plate 11 are secured together by a bolt 15 and a shouldered pillar 16, each screw-threaded at its lower end; which respectively are passed through socket holes 17, 18 through spacer nuts 19, 20 and screwed into tapped holes 21, 22 in plate 11. The nuts 19, 20 are tapped at their upper ends only and become captive spacers which are clamped between the plate 11 and shoulders 26, 27 of the bolt 15 and pillar 16 when the bolt head and a shoulder 28 on the pillar make clamping engagement with the upper face of socket member 7. A notched retaining plate 34 is mounted on the top of pillar 16 for engagement with all four relays and can be rotated to position notch 36 for release of any one of them. An insulating sheet 32 may be located between the plate 11 and frame 12. In a modification, additional sockets are provided for relay contacts and in a further embodiment relay-retaining means are provided on two pillars carried by an adapter plate but taking no part in securing it to the socket member. Specification 716,503 is referred to.

Title: Improvements in and relating to reduction gear
IPC: F16H3/00
Filed: 1920-12-08
Abstract: 155,202. Gehrig, J. Dec. 8, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Turning-gear.-In motor-cars in which the lighting-dynamo is used for starting the engine through reduction gearing, the dynamo shaft 2 carries loosely a wheel 7 gearing, through intermediate pinions 19, 18 carried by a disk 8, with a toothed ring 16 on a plate 17 geared by a chain to the engine. The disk 8 is carried loosely by and moves with a nut 4 to which the wheel 7 is secured and with which engages a screw-thread 3 on the dynamo shaft 2, projections 5, 6 on the nut engaging with lost motion with lugs 9, 10 turning with the shaft 2. The disk 8 carries a cone 12 which engages a stationary cone 14 under the action of the screw and nut when the engine is being started so that the wheels 18, 19 act as a reducing-gear, while, when the engine starts, the excessive speed of the nut 4 brings a, cone 13 on the disk 8 into engagement with a cone 15 on the plate 17, so that the plate 17, the gearing and the dynamo rotate solid.

Abstract: 1434554 Transistor circuits ROBERT BOSCH GmbH 20 July 1973 [24 July 1972] 34730/73 Heading H3T [Also in Division G4] A flasher unit for operating the lamps 10 or 11 of a motor vehicle comprises a flasher switch 14, an astable multivibrator including an amplifier 20 having its two inputs connected to the diagonal ends of a resistor-capacitor bridge 29-32, the switching periods of the multivibrator being determined by the change in charge of the capacitor 32 between two threshold potentials, a switching stage 39 responsive to the amplifier output for activating the flashing of lamps 10 or 11, and a switch 57 for varying the operating frequency of the flasher in dependence upon the operating state of the lamps by changing at least one of the threshold potentials. A switching circuit 49, 51, 91 enables astable operation only when a flasher switch 14 is in the operative position. In operation, initially capacitor 32 is in the discharged state and amplifier stages 21, 35, 37 and the switching stage 39 are off. Capacitor 32 charges up via a resistor 31 to an upper threshold potential present at junction 33 when the above non-conducting stages are rapidly rendered conducting and stage 22 is cut off to set (via 35, 37 and 39) a lower threshold potential at junction 33. Capacitor 32 now discharges via resistor 31 and the stage 39. A relay 19 is energized and contact 15 closes to supply power directly to the lamps. Flashing occurs at a rate determined by the astable operation, i.e. the charge and discharge of capacitor 32. In the event one of the lamps fail, a switch 57 is rendered conducting to reduce the charging period which is manifested by an increase in the flashing rate of lamps 10, 11 as well as a monitor lamp (not shown). A switching transistor 82 assures that the first flashing period is the same as the following periods. A leakage resistance 56 formed by an open-base transistor is provided for by-passing residual currents present in the circuit 20. A capacitor 83 as well as a further capacitor connected between junctions 33, 34 provide interference suppression. In a switch 60 for controlling the switch transistor 57, if the voltage drop across a check resistor 17 is greater than that across a resistor 65, then transistors 78 and 57 are off. If the above condition is reversed, then transistors 78, 57 are turned on. Transistors 76, 77 provide temperature stabilization. The arrangement 68 provides a constant current. Fig. 2 (not shown) relates to an improved interference protection arrangement for switch 60.

The first crusher comprises two peripherally-toothed discs 9, 10 carried by a shaft 7 driven from a motor 6 and coacting with an inwardly-toothed rim 11 removably mounted in the cylinder. The second crusher consists of three toothed discs on the shaft 7 coacting with four toothed rims 15, 16, 17, 18 in the cylinder. More peripheral teeth are provided on the discs and rims of the second crusher than on those of the first crusher, and successively lower discs and rims in the second crusher have increasing numbers of teeth. All the teeth are bevelled on their upper and lower faces so as to provide either parallel gaps or converging gaps. The lower end of the cylinder 4 also mounts the screen 20, over which rotates a blade unit comprising two blades 22, 22<SP>1</SP>, Fig. 2, hinged at 23, 23<SP>1</SP> to a support 24 on the shaft 7 and urged downwardly by springs 25, 25<SP>1</SP> so that their curved lower edges contact the screen. The screen 31 is vibrated by a motor 33. Either the discs or rims may be rotated or both may be rotated or oscillated so as to have relative motion.

Title: Improvements in or relating to the production of quinone and hydroquinone
IPC: C25B3/23
Filed: 1933-12-16
Abstract: A benzene solution of quinone produced by electrolytic oxidation of benzene is subjected to reduction at about the boiling point of benzene under such conditions that the benzene is immediately distilled off and the hydroquinone dissolved in water. For example, the solution may be run into a vessel containing iron borings and water maintained at about 80 DEG C.; benzene distils off and the hot saturated liquors are drawn off, filtered hot and the hydroquinone crystallized out therefrom.  Alternatively the quinone-benzene solution may be run into a still containing water into which sulphur dioxide is passed.  Benzene distils off and the solution is withdrawn at intervals and acid removed by alkali metal carbonate or hydrate, hydroquinone then being obtained by evaporation.  Detailed examples are given.
