Title: Air-intake arrangements for carburettors for automobile vehicles
IPC: F02M35/10
Filed: 1934-11-20
Abstract: 434,065. Carburetters ; silencers. SOC. ANON. SOLEX, 190, Avenue de Neuilly, Neuilly-sur-Seine, France. Nov. 20, 1934, No. 33381. Convention date, Oct. 27. [Classes 7 (ii) and 7 (iii)] [See also Group XXXI] The transmission of the sound of the air intake of the carburetters of motor vehicles to the occupants is reduced by directing the air inlet away from the occupants and causing the air-inlet pipe partly to lubricate the carburetter, which thus acts as a screen. The Figure shows an ordinary carburetter 4 which has the inlet 2 directed forwards, the conduit 3 and float chamber 6 acting as obstacles to screen the transmission of sound rearwards. The air inlet may be directed sideways with a horizontal carburetter, upwards and forwards with a vertical carburetter, and downwards with a down-draught carburetter. A flange 5 may be provided on the inlet of sound reflecting or absorbing material.

Title: Improvements in lathes and like machines having automatic traversing-gear
IPC: B23Q16/00
Filed: 1920-11-26
Abstract: 154,547. Bechler, A. April 9, 1918, [Convention date]. Turning.-A lathe has an automatic stop mechanism for the traversing feed set by means of a scale. The chain-driven lead-screw a comprises a clutch portion b, which may be disengaged by means of a projection c on a cursor d adjustable on a bar f carried by the tool carriage. A scale e is so fixed to the lathe bed that the clutch is disengaged when the cursor indicates zero on the scale. Thus from any position of the carriage any desired traversing-feed may be obtained by fixing the cursor at the required distance on the scale. In a modification, the scale slides in guides on the lathe bed and carries a projection which disengages the clutch when a hook carried by the carriage contacts with an adjustable cursor on the scale. In a further modification, the clutch b is dispensed with, and a cursor sliding on a fixed scale actuates a device to disengage the tool carriage from the lead-screw at the required point.

Abstract: 1,048,573. Machinery guards; universal Joints. LICENTIA PATENT - VERWALTUNGS-G.m.b.H. Aug. 23, 1963 [Aug. 23, 1962], No. 33511/63. Headings F2J and F2U. [Also in Division B1] A shaft arrangement comprises an input shaft in a first non-rotary housing, an output shaft in a second non-rotary housing, a detachable coupling between the two shafts, a detachable coupling between the two housings, and a single bearing free in a spherical seating in the second housing to journal the output shaft. As applied to a portable domestic mixing machine, a motor-driven input shaft 7 carries a sleeve 12 having axial slots 14 at its end to receive a cross-piece 11, e.g. a pin at the end of a spring 13. The end of the sleeve 12 has also a part-spherical socket to receive freely the part-spherical end 10 of a universal joint member 6, a transverse slot across the partspherical end of the universal joint member engaging over the cross-piece 11 in the sleeve. The universal joint member 6 is secured by a pin 9 to an output shaft 4 journalled at its remote end by a spherical bearing member 5 in a detachable non-rotary housing 3. A non- rotary housing 1 surrounding the input shaft 7 supports the housing 2, the two being connected by a bayonet-and-socket joint. In the engaged condition, a spring 16 biases a cupshaped member 15 slidable in the housing 2 against a flange 19 in the housing 1, an outer sealing ring 18 engages a shoulder on the housing 2, and the two shafts 2, 4 are drivingly connected through the universal joint 6. To disconnect the coupling, the housing 2 is turned relatively to the housing 1, from which latter it can then be withdrawn, the spring 16 pushing the cup-shaped member 15 upwards so that an inner sealing ring 17 contacts the universal joint member 6 to support the output shaft 4 centrally of the housing 2. At the same time, the slot at the end of the universal joint member 10 disengages from the cross-piece 11 in the sleeve 12. To reconnect the coupling, the housing 2 is pushed up into the housing 1 so that the flange 19 is engaged by the cupshaped member 1, which releases the output shaft 4. The part-spherical end of the universal joint member 6 slides into its socket in the sleeve 12, and the slot at its end re-engages the cross-piece 11. The housing 2 is then turned relatively to the housing 1 to lock it in position.

Class 142(2) In a ribbon loom in which the front part of the shuttle is changed to replenish the weft as in Specification 792,344, the spent shuttle front 6 is ejected by the lowermost tooth of the pusher 2 and the fresh shuttle front 7, is inserted by the next tooth, the remaining shuttle fronts in the magazine being simultaneously advanced by other teeth on the pusher. The fresh shuttle front 7 is pushed slightly beyond its correct position in the rear part 9 of the shuttle, but is located by a ball catch 13 as the pusher retracts. The pusher is resiliently mounted so that on its upward movement the teeth ride past the shuttle fronts, which are prevented from rising by latch springs 15. The ejected shuttle front 6 remains on a support 10 until the next replenishment. French Specification 1,025,424 is referred to.

Title: Spark discharge machining
IPC: H01C17/24
Filed: 1976-08-16
Abstract: 1517577 Automatic control of electroerosion FERRANTI Ltd 16 Aug 1976 [14 Aug 1975]  33874/75 Heading G3R [Also in Divisions B3 and H1] In a spark discharge machining process, an electrode connected to an electrical energy storage device is moved towards and away from a workpiece. The energy storage level is controlled by a charging circuit responsive to changes in the level caused by contact between the electrode and the workpiece when the stored energy is insufficient to produce surface erosion following recharging, the circuit operates to reduce the charge level at a predetermined rate. As shown in Fig. I, an electrode 11 is used to make cuts in a thin film resistor 12 so as to adjust its resistance to a desired value, Fig. 2 (not shown). The electrode is vibrated axially towards and away from the resistor and also moved laterally so as to vapourize the metal film along a desired path. The electrode is connected to an energy storage device 19 which may be a capacitor or an inductor charged from a supply line 17 over a resistor 18 and control circuit 20. The circuit 20, Fig. 3, includes a voltage level control 23 formed by transistors 25, 28, and a regulating arrangement 24 consisting of a Darlington pair 31 which controls the charging of a capacitor 34 in dependence on a high pass filter circuit 36, 37 feeding back a signal from the storage capacitor 19. In operation, the capacitor 19 is sufficiently charged to render the transistors 31 conductive, so that the capacitor 34 discharges slowly, causing a steadily reducing voltage to be produced at the collector of transistor 25 and therefore at the electrode 11. As the electrode is moved towards the workpiece, a series of spark discharges take place, until the voltage becomes insufficient to vapourize the metal film. Contact then occurs, and the capacitor 19 is discharged by a current pulse which is passed by the filter 36, 37 and turns the transistors 31 off for a time related to the change in capacitor voltage. During this time, the capacitor 34 is charged by the supply over a resistor 32 and diode 33, thus increasing the voltage applied to the electrode 11 by the capacitor 19, and enabling spark machining to continue. An internal feedback connection 30 ensures at least a minimum voltage on the storage capacitor 19 even if the capacitor 34 is discharged.
