Title: Improvements in or relating to direction indicators for vehicles
IPC: B60Q1/42
Filed: 1928-01-13
Abstract: 283,889. Stammer, H. Jan. 19, 1927, [Convention date]. Road-traffic signals on vehicles.-A direction indicator for use on road vehicles is rendered operative by a manually set switch and is associated with means under the control of the steering wheel for nullifying the signals automatically when the new direction has been assumed, the said means comprising a spring contact mounted longitudinally on the steering column to cooperate with a pair of resiliently mounted tongues on an insulated sleeve surrounding the column and carrying contact blocks one or other of which is engaged by the, spring contact to close the circuit of a solenoid to open the corresponding switch on the return of the steering wheel. As shown in Figs. 1, 3, and 4 the steering column is surrounded by a sleeve q of insulating material to which is secured a disc o carrying insulated arms n on which are mounted contact blocks k and m and laterally extending spring arms p. An insulated contact spring r on the steering column is normallv located between the two arms n. The indicators which may be lamps with transparent arrows a, b are connected through contacts f, g to a source of current e by means of switches c, d. These switches are adapted to be moved to the "off" position by means of solenoids h, i, the windings of which are connected to the battery e and contact blocks k, m respectively, the contact spring r being connected to the other side of the battery. When a switch is operated to give a signal and the steering wheel turned the contact r moves round beneath the spring p, the signal indication being maintained. On the return movement of the steering wheel the contact r rides up over the spring p and near the end of the movement closes the circuit of the solenoid through the contact block k or m whereby the switch is moved to the "off" position. The Specification as open to inspection under Sect. 91 (3) (a) states also that one-way ratchet and pawl devices may be employed to effect the return of the indicators. This subject-matter does not appear in the Specification as accepted.

IPC: B21F27/18
Filed: 1966-01-11
Abstract: 1,102,311. Centrifugal strainer basket. AMERICAN FACTORS ASSOCIATES Ltd. 11 Jan., 1966, No. 1211/66. Heading B1D. [Also in Division B3] A basket for a centrifugal strainer (Figs. 1 to 4, not shown) provides support for an internal filtering cloth or wire screen and comprises a helical coil of stainless steel wire of flat crosssection supported in turn by external axial ribs and upper and lower rings, all welded to the wire at their intersections. In Fig. 1 the ribs carry a conical shroud (15) and the upper ring (14) carries a dependent shroud (17), for the guiding of filtrate. In Fig. 2 the ribs are in two pieces, forming V-shaped sections, and are supported by outer, axially spaced rings (30- 35). The baskets shown are frusto-conical, but a cylindrical basket is mentioned. In manufacture, wire is fed by driven rolls (55, 56) (Fig. 14, not shown) through straightening roller assembly 41 (Fig. 13, not shown) to peripherally grooved rolls 110, 111. 112. Roll 112 is progressively advanced towards roll 110 by means of a cam (135) (Fig. 6, not shown), which is moved by a handle (140) or by a drive 150 - - (155) from the drive rolls (55, 56). Thus the curvature given to the wire is increased to form a helical, conical coil which is wound on to assembly 160-164. The coil is then placed on a welding jig (Fig. 7, not shown), which comprises circumferentially spaced bars (190), with external notches (191) to receive the wire (Fig. 12, not shown), and a single rib-supportng frame (200) which is rotatable round the jig to hold successive ribs or pairs of ribs (Fig. 11, not shown), against the coil for welding thereto. The jig also supports the end rings (10, 14) for welding to the ribs and wire ends. The jig is constructed for easy dismantling from inside the finished basket. Figs. 15, 16 (not shown) illustrate a further jig which is mounted on the shaft of that in Fig. 7, after removing rib supporting frame (200), to hold the external rings of the Fig. 2 embodiment while they are welded to the ribs.

Title: Esters of methacrylic acid and their manufacture
IPC: C07C69/54
Filed: 1936-01-14
Abstract: Methacrylic acid esters of aliphatic polyhydric alcohols in which all but one of the hydroxyl groups have been replaced by substituent groups, other than amino groups, are manufactured by reacting such alcohols with a lower ester of methacrylic acid in the presence of an ester-interchange catalyst, or with a methacrylyl halide.  Suitable starting materials are: glycerols or mono-, di-, tri-, tetra-, penta- and higher alkylene glycols in which all but one of the hydroxyl groups have been replaced by a substituent, such as an ester, ether, halide, nitrate or cyanide, e.g. ethylene and propylene glycol monomethyl, monoethyl, monopropyl and higher ethers, higher substituted methylene glycols such as tetramethylene, pentamethylene and decamethylene glycol monoalkyl ethers, dialkyl glycerols such as the dimethyl, diethyl and methyl ethyl ethers, and the corresponding esters, halides, nitrates and cyanides, such as ethylene, diethylene and propylene glycol monoacylates, glycol mononitrate, and ethylene glycol monocyanide.  In examples: (1) sodium is dissolved in ethylene glycol monoethyl ether and the alcoholate is heated with methyl methacrylate in the presence of hydroquinone, producing ethylene glycol monoethyl ether methacrylate; (2) ethylene glycol monomethyl ether is heated with methyl methacrylate, benzene, hydroquinone and sulphuric acid, yielding ethylene glycol monomethyl ether methacrylate; (3) diethylene glycol monobutyl ether is heated with methyl methacrylate, sulphuric acid and hydroquinone to produce diethylene glycol monobutyl ether methacrylate; (4) ethylene chlorhydrin is reacted as in (2) to produce b -chlorethyl methacrylate.  Polymerization products are manufactured by polymerizing the esters described above by the processes described in Specifications 465,789 and 467,900, if desired with the addition of the modifying agents enumerated therein.  The polymers, interpolymers, mixed polymers and syrupy partial polymerization products may be employed for the purposes set out in the said Specifications.  In examples: (5) ethylene glycol monoethyl ether methacrylate is heated in aqueous methanol solution with benzoyl peroxide; (6) ethylene glycol monomethyl ether methacrylate is similarly polymerized and the product is moulded to a disc; (7) ethylene glycol monomethyl ether methacrylate is heated with benzoyl peroxide; (8) diethylene glycol monobutyl ether methacrylate is polymerized as in (5); (9) b -chlorethyl methacrylate is similarly polymerized, and the product is moulded to a disc.  Specification 15271/14, [Class 2 (iii)], also is referred to.

Abstract: 752,892. Linear-dimension gauges. SHEFFIELD CORPORATION. Jan. 15, 1954 [March 3, 1953], No. 1229/54. Class 106 (2). A linear dimension gauging head for use with an air or other fluid flow gauge comprises a work. engaging member or spindle 10 having a passage 12 communicating with a fluid pressure supply and also with pockets 16 formed as counterbores in the spindle 10 and containing workpositioned balls 15, 15<SP>1</SP> which are freely rotatable in the pockets and which, by limited axial movement in the pockets in accordance with the dimension of the work being gauged, co-operate with shoulders 17 at the inner ends of the pockets to control the leakage flow to exhaust channels 18 opening in the surface of the spindle 10 and communicating laterally with the pockets 16. The balls are retained in the pockets 16 by removable snap rings 20 seated in annular grooves 21. The ends of the snap rings have little clearance between them when the ring is seated so that they have to be overlapped to remove the rings. The exhaust channels 18 are askew to the axis of the spindle to allow easy entry of the spindle in the hole to be gauged. The pockets 16 are connected to the passage 12 by radial passages 14. The groove 18 communicates with a longitudinal air escape groove 19. The balls are slightly spaced from the shoulders 17 of the pockets 16 when the outer surfaces of the balls are tangential to the surface of the spindle 10.

Title: Improvements relating to Devices for Cutting and Slicing Fruit and Vegetables.
IPC: A47J17/00
Filed: 1916-01-26
Abstract: 100,040. Beacon Lighting Co., (Assignees of Aiken, T. M.). Jan. 27, 1915, [Convention date]. Cutting slices in succession; removing cores and eyes from fruit and vegetables.-A hand device for slicing fruit and vegetables with an adjustable uniformity of thickness of cut consists of a piece of sheet metal shaped or pressed so as to form a flat guiding-surface B, side wings C, having inclined straight parallel bead-like grooves D, and a hollow casing E which may be continued, as shown in Fig. 6, to form a peeler and corer K, or may receive a removable handle G which is extended within the casing E to form a peeler and corer F. The grooves D receive stiff wires M, which are secured rigidly to a metal blade L having a cutting-edge l. The cutter is adjustable towards or from the surface B, so as to enable different thicknesses of slice to be cut, by means of a cross-bar N connecting the two inclined parallel rods or wires M. When adjusted as required, the wires may be locked. in position by the hook-like extremities P of a gripping-plate 0 hinged on the bar N. When no clamp is used, as shown in Fig. 6, the guides D must be formed at a greater angle to the surface G so as to prevent the cutter from being pulled out when drawn over the article to be sliced.

Abstract: 1382071 Photographic processes; photomasks; electrostatic imaging CANON KK 11 Jan 1972 [11 Jan 1971 18 Jan 1971] 1271/72 Headings G2C G2H and G2X [Also in Divisions B6 C7 and H1] Relief images are produced by imagewise exposing a material comprising a support, a layer of chalcogen glass (i.e. a glass-like material containing at least S, Se or Te) and a layer of a metal, an alloy thereof, a semi-conductor containing Si or Ge, a semimetal of Gp.V (e.g. As/Sb) or S, Se or Te provided that it is different from the chalcogen glass which causes the production of a mutual diffusion product at the exposed areas and then removing the unreacted areas of the metal layer. As shown, a support 3 on which a chalcogen glass layer 2 and a metal layer are vacuum deposited is imagewise exposed to produce mutual diffusion products 10 in the exposed area. The metal layer is removed to produce a relief image Fig. 3 (not shown) and the chalcogen glass may also be removed to produce relief image as Fig. 4. Specified metals are Ag, Zn, Cd, Mn, Ga, Cr, Cu, In, Bi, Sn, Tl, Ge and Te and alloys thereof. Specified chalcogen glasses are S, Se, As/S, As/Te, As/Se, S/Si, Se/S, Se/Te, Sb/Se, Bi/Se, Bi/S, Bi/Te, As/S/To, As/S/Se, As/Se/Te, As/S/Se/Te and Sb/As/S. The material may be uniformly heated before exposure to reduce exposure time. The metal layer may be removed by dissolution e.g. an acid or oxidizing liquid, by using mercury to form an amalgam or by ion bombardment. The support may be glass a polymer or a metal (of non-reactive with the chalcogen glass). Generally the relief image produced is used as a photo-mask or microphotograph as the optical density of the mutual diffusion product is 1À5 or higher than the chalcogen glass at wavelengths of 4360Š and less. Preferably, the unreacted chalcogen glass is also removed (using an aqueous solution of NaOH or Ba(OH) 2  or an alcohlic solution of KOH) leaving the mutual diffusion product (opaque at 5460Š but transparent at 4360Š and below) on a transparent support as a photomask. Before the removal of the chalcogen glass, the relief image may be uniformly heated or exposed to light to ensure that the mutual diffusion image is rectangular and not undercut near the support. Alternatively, the relief image may be used to produce electro-photographic  images, the mutual diffusion product having low resistivity so that on charging and toner development a coloured image is produced on the chalcogen glass. The chalcogen glass may be removed as above and an electro-photographic image may be formed as above on either the support or mutual diffusion product depending on which has the higher resistivity. Metal plated images may be produced from the relief image by electro-plating which preferentially dissolves the mutual diffusion product and plates the support; however the unexposed chalcogen glass is also slowly removed so that the final product is a metal plated image on the support (of Example 25).
