Title: Method and Apparatus for Side Grinding Flats on a Carding Machine
IPC: B24B19/18
Filed: 1968-06-21
Abstract: 1,198,936. Grinding teeth of card flats while in operative position. ASHWORTH BROS. Inc. 21 June, 1968 [27 June, 1967; 5 March, 1968], No. 29736/68. Heading B3D. The teeth of card flats 10 are ground while the card flats are in their operative position on the carding machine 8 by a grinding head 20 having a plurality of abrasive surfaced, rotating discs which are located between adjacent rows of teeth on the flats, the head 20 being reciprocated across the flats transversely of their direction of movement. The card flats 10 are arranged in spaced parallel relationship and the rows of teeth 18 are arrayed parallel to the direction of movement of the flats. The relative speeds of the flats and the reciprocational movement of the grinding head are such as to ensure that the discs pass from one row to another row only in the open spaces between the teeth on adjacent flats. The card flats can be driven from the drive of the carding machine but can also be driven independently at a faster speed for quicker grinding when no carding is taking place. The means for reciprocating the grinding head consists of a rotatably mounted hollow drum 24 with a cross-threaded screw-shaft 26 rotatably mounted therein. The head slides on the drum due to the drum and shaft rotating at different speeds through a transmission gear means 34 and a follower on the head engaging the screw-shaft.

Title: Continuous automatic hydraulic machine
IPC: B23Q11/00
Filed: 1928-10-17
Abstract: 302,889. National Automatic Tool Co., (Assignees of Galloway, R. M.). Dec. 23, 1927, [Convention date]. Drilling-machines.-An automatic machine tool comprises a reciprocating tool head and a movable work carrier, each operated by hydraulic means from a common pump, controlling means being provided whereby the tool head and work carrier are operated alternately. In the multiple spindle drilling machine shown in Figs. 1 and 4, the tool head H is connected to a piston 21, controlled by a valve D, and the rotary work table T is operated through ratchet gearing and a rack 18 from a piston 24 controlled by a valve E. Pressure liquid is supplied from a reservoir R by a pump P provided with a bye-pass and relief valve x limiting the maximum pressure in the system. When the valves D E are in the positions shown in Fig. 4, the tool head is held retracted and pressure liquid moves the piston 24 to the left, thus moving the member carrying the pawl 15 on its non- working stroke. At the end of the movement, an arm 68 operates the valve E to cause the return of the piston 24 and the operation of the table T by the pawl 15; the arm 68 also moves a rod 67 by engagement with a stop 67<a> so that a pawl 71 is moved into engagement under a collar 72 on a rod 41 carrying the valve D. When the piston 24 has been returned to the position shown and the movement, of the table completed, the arm 68 through a stop 67<b> moves the rod 67 so that the pawl 71 lifts the rod 41 against the action of a spring 48; spring-urged interference members 43, 44 are thereby permitted to bring offset parts into position beneath a collar 42, and the valve D is moved into its uppermost position, so that pressure liquid passes through pipes 35a, 35<b> and forces the tool head H down at a maximum rate. A stop 46 on the tool head later moves the interference member 43 so that the spring 48 moves the valve D to an intermediate position closing the pipe 35a, the movement of the head then continuing at a slower rate; finally a stop 47 acts on the member 44 and permits the spring 48 to move the valve D into its lowermost position, so that liquid is admitted under the piston 21 to raise the head. Near the end of the upward movement, a stop 64 acts through a collar 63 to reset the valve E for the next cycle of operations.

Title: Improvements in or relating to electroluminescent devices
Inventor: BERGH ARPAD ALBERT
IPC: H05B33/00
Filed: 1970-06-23
Abstract: 1292392 Electroluminescence WESTERN ELECTRIC CO Inc 23 June 1970 [23 June 1969] 30341/70 Heading C4S [Also in Division H1] An electroluminescent device comprises a body with a P-N junction 11 and composed of at least 36% weight gallium phosphide, the remainder (if any) substantially gallium arsenide, wherein at least one macroscopically plane surface of the body has surface protuberances whereby the area of the surface, ignoring atomic irregularities, is at least 50% greater than its geometric plane area. The surface may be produced by immersion in a preferential etchant such as hydrofluoric acid, grinding, sandblasting or liquid honing, and may be regular such as machined grooves. The protuberances should possess a maximum angular deviation > critical angle from the average surface plane. Reference is made to a GaP refractive index of 3À2, and GaAs and GaP being respectively absorptive and transmissive of their own emissions. Roughening of the surface is indicated as producing a diffuse radiator obeying Lamberts Law and also reflecting light back into the device at random angles and not trapping the reflected light as would a smooth surface. The diode may have a polished lower surface and roughened upper surface (Fig. 1), vice versa in Fig. 2 (not shown), both with polished sides, and a lower surface with periodic machined grooves (Fig. 3, not shown) and immersion of a device as in Fig. 4 (not shown) in HF etchant, for 15 mins., produces roughening of surface (42) generally in the 111 plane and parallel to the PN junction, to improve radiation emission in the perpendicular direction. Area (43) is also a roughened area but is indicated as not corresponding to the present invention. The construction is stated to produce no benefit for n # 1À4. Generally it is required the ray intensity is attenuated by <50% as the ray traverses a path length equal to 3 times the body thickness, e.g. GaP attenuates by 20% in a distance 3 times a 0À013 body thickness. Direct band gap GaAs mixed with indirect band gap GaP effects a band gap transition at 36% GaP-64% GaAs. Multileaded EL devices such as transistors are instanced and reference made to other than plane diode junction configurations.

Filed: 1975-07-21
Abstract: 1504061 Time switches EDERLAN S COOP 21 July 1975 [19 July 1974 26 Oct 1974 28 May 1975] 30481/75 Heading H1N A programming device which provides the relatively high number of contacts suitable for a clothes washing machine in a substantially flat structure suitable for dish washing machines comprises two cam discs 17 and 18 which actuate contacts, disc 17 serving as a programme cam support driven intermittently so that it moves relatively slowly and the other disc 18 being driven generally continuously and relatively rapidly by a motor 20 via reduction gearing 22, the said discs 17, 18 lying substantially in the same plane with their shafts parallel, and the motor and part of the transmission mechanism being mounted on the side of a casing for the device remote from the slow-moving disc 17 with the shafts thereof perpendicular to those of the cam discs; detent means for locating the angular positions of disc 17 and means for programmed stopping of stepping are also provided. An array of change-over contact sets, with followers (12 or 13, Figs. 3, 4 and 5, not shown) moving parallel to the shafts of the cam discs, extends generally parallel to the plane of the discs 17, 18. A printed circuit board 36 may be provided for auxiliary low current contacts. The stepping mechanism 19 may be driven by a snail cam 35 integral with disc 18, or by means of a swinging idler pinion (33, Figs. 19 and 20, not shown) which couples 19 to 18 under control of disc 17. A resiliently rocking pawl (29, Figs. 21 to 25) acts like an escapement on the toothed edge of disc 17 to locate the angular positions of the disc between steps. As shown, an electromagnetic solenoid 21 acts on a clutch formed by gears 26, 27 such that when solenoid 21 is energized the disc 17 is rapidly advanced by direct drive from shaft 24 via gears 25, 26, 27 and 28. Contacts (31, Figs. 14 and 15, not shown) may be operated by the solenoid for disconnecting all or some of the elements of the washing machine during rapid advance of disc 17. Control by parameters such as water level or temperature may be effected at a specific point in the programme by the provision of a pivoted bar (51, Figs. 26, 27, and 28, not shown) on disc 17 which is urged by a fixed stop (52) to close the gap between two drive teeth such that stepping ceases until a "rapid advance" through one step renews the drive; more than one bar (51) may be provided. Alternatively, the electromagnet 21 may be used to stop the stepping (instead of for rapid advance). In this case its armature acts on a pivoted arm (23, Figs. 7, 10, 11 and 16, not shown) to interfere with a lug (34) and prevents stepping mechanism 19 from functioning until the electromagnet 21 is de-energized upon attainment of a desired value by an external parameter (such as water level or temperature).

Abstract: 1,145,367. Heated windows. COMPAGNIE DE SAINT GOBAIN. 7 July, 1966, No. 30581/66. Heading H5H. [Also in Division C7] A vehicle window comprises a glass sheet 18 having on one or both surfaces electric heater resistance bands 5 composed of a suspension of silver and a sintered substance in an organic binder deposited thereon in paste form, dried, and subsequently fired during a heat treatment for curving and/or tempering the glass. Current collector bands (6, Fig. 5) similarly deposited are connected to the feed circuit by a spring clip (40, Fig. 6) and lead (45). If the resistance of all or some of the deposited heater bands 5 is too high, at least a part of these bands are thickened by electro-deposition of copper. The parts not to be thickened are masked by a plate, or a protective readily removable varnish, or the shape and position of the cathodes are adjusted. The heater bands 5 are deposited by a silk-screen process, or the suspension is ejected under pressure from a syringe or gun 9, Fig. 8, in the form of a filament. The deposition apparatus, Fig. 8, comprises a frame 20 movable in the direction F along rails 22 on a table 19 on which the cold and cut-to-size glass sheet 18 is placed; a carriage 23 slidable in the direction G on frame parts 24; a plurality of syringes or guns 9 (Fig. 7), one for each band 5, on the carriage and having a nozzle (12) for discharge of the paste. If the bands 5 are to be parallel curves, a single or plurality of curved templets 25 engageable with a wheel 27 on the carriage determines the path of the syringes and hence of the bands. If non-parallel curved bands are desired, each syringe is mounted on a pivoted arm 29 and has a wheel 30 travelling in an additional guide slot 26 corresponding to the path of the band. When the bands 5 are straight lines, frame 20 is driven at a uniform speed in direction F. When the bands are curved, frame 20 is driven by a constant speed chain 32 guided to follow a templet 33 of the same curvature as templet 25, a wheel 34 on the chain engaging a frame part 35. The heating conductors may define oblongs or squares, and may cross.
