Title: Lane defining apparatus for handling articles in columns
IPC: B25J15/00
Filed: 1974-02-13
Abstract: 1406408 Stopping and transferring conveyed articles; filling crates EMHART CORP 13 Feb 1974 [2 March 1973] 6546/74 Headings B8A and B8C Articles A in three conveyer lanes proceed on to a platform until they engage probes of respective lane detection devices 12. When at least two of the latter are activated, air is supplied to inflatable diaphragms 54, each forming part of a respective partition 32. The articles in each lane are thus gripped between one of the partitions 32 and one of two outer rigid partition members 34. Each diaphragm 54 is disposed between flexible resilient steel plates 60 and 62. These remain parallel as shown in Fig. 5, under zero inflation of the diaphragm 54, but deflect under expansion when the latter is inflated. The platform may be swung through 180 degrees to invert the articles, so that when pressure is released the latter may be dropped into a crate &c.

Abstract: 549,580. Sparking plugs. BENDIX AVIATION CORPORATION. May 23, 1941, No. 6662. Convention date, July 9, 1940. [Class 7 (iv)]  A sparking plug comprises a central electrode assembly in which the spaces in or between the parts are at least partly filled with an insulating material consisting of a synthetic resin derived from a cashew-nut shell oil. As shown, the stem 11 of the electrode 12 has a drive fit in a copper or soft-metal sleeve 13 surrounded by a mica sleeve 14 and stacks 15, 17 of mica washers. The stack 17 is engaged by a washer 18 over which the counterbored end of the stem 11 is peened. The sleeve 14 is tightly fitted in a member 7 threaded in the body member 5 and having a shielding extension 8 lined by an insulating sleeve 16. The insulating parts surrounding the stem 11 are embedded in a filling material prepared by polymerizing cashew-nut shell oil in the presence of sulphuric or other acid and condensing with a aldehyde such as paraformaldehyde and a small quantity of xylol, linseed oil or other solvent or thinning agent. The liquid obtained is forced into the crevices of the insulation after evacuating the air; excess liquid is squeezed out by axial pressure, and the assembly is baked at a gradually increasing temperature.

Filed: 1917-05-10
Abstract: 116,517. Parsons, Sir C. A., Parsons Marine Steam Turbine Co., and Aldis, A. J. May 10, 1917. Blades.-Relates to blade-fixing devices wherein the containing groove is formed with lateral projections, and consists in forming the individual packing members in two or more parts, each contiguous with not more than one side of the groove, so that they may be inserted in their proper positions without driving round the groove, the said groove being formed as wide as the blade while the packing-pieces are arranged to fill the whole space between successive blades and the sides and bottom of the groove. In one example, Figs. 1,2, and 3, the blade b is introduced radially into the groove a and twisted round into position, its lateral recesses engaging the projections c, and the divided packing-sections d, e are then successively inserted. The last packing-piece, which may be formed with a beyelled edge p, is inserted at a place where the projection c is locally removed, and a projection j left at this place on the rotor is hammered down on the bevelled edge. The line of division of the packing-pieces may be inclined to the plane of the groove, and a central wedge-piece may be inserted between two sidepieces. The blades may be serrated to facilitate effective caulking, or pins l, Fig. 17, may be driven through holes k, Fig. 19, or the blades and packing-pieces may be threaded on to short lengths of wire. Four packing-pieces may be inserted in the order 1, 2, 3, 4, 5, Figs. 6 and 7, and the piece 3 may be wedge-shaped. The last pacliing-piece may be fixed by screws or locking-pieces of the usual type. Some or all of the packing- sections may be secured to the fronts or/and the backs of the blades.

Abstract: The invention comprises compounds of the general formula <FORM:0923702/IV(a)/1> in which R and R1 and alkyl, cycloalkyl, aralkyl, aryl or heterocyclic residues which may be substituted and which alkyl residue may be interrupted by at least one oxygen atom, R2 is a hydrogen atom or an alkyl or acyl residue containing at most 4 carbon atoms, R3 is a hydrogen atom or an alkyl residue containing at most 4 carbon atoms, R4 is the group -CH2-, -CH2-CH2- or -CH(R5)- in which R5 is an alkyl residue containing at most 4 carbon atoms and X is an oxygen or sulphur atom.  They may be obtained by reacting a compound of formula (RO)(R1O)P(X)SMe in which Me is a salt-forming cation, especially in alkali metal, with a compound of the formula Hal.R4.CON(OR2) (R3) in which Hal is a halogen atom, e.g. Br or Cl. The reaction may be effected at ordinary or elevated temperature, e.g. within the range of 0 DEG  to 120 DEG C. and an inert solvent, e.g. an alcohol or ketone, may be present, or water may be added.  If desired the reaction may be carried out in an atmosphere of an inert gas, e.g. nitrogen, and/or under reduced pressure.  Several examples are given and the products have pesticidal properties (see Group VI).ALSO:A pesticidal composition comprises, in admixture with a liquid, gaseous, or solid diluent, an organo-phosphorus compound of the general formula <FORM:0923702/VI/1> in which R and R1 each represent an alkyl, cycloalkyl, aralkyl, aryl or heterocyclic residue which may be substituted and which alkyl residue may be interrupted by at least one oxygen atom, R2 is a hydrogen atom or an alkyl or acyl residue containing at most 4 carbon atoms, R3 is a hydrogen atom or an alkyl residue containing at most 4 carbon atoms, R4 represents the group -CH2-, -CH2, -CH2-, or <FORM:0923702/VI/2> in which R5 is an alkyl residue containing at most 4 carbon atoms, and X is an oxygen or a sulphur atom.

Abstract: 838,333. Electrolytic capacitors. PLESSEY CO. Ltd. March 6, 1957 [March 6, 1956], No. 6989/56. Class 37. [Also in Group XV] In the manufacture of electrolytic capacitors, such as those described in Specification 836,392, in which two continuous conducting electrode foils 10, 13 are brought together with at least one insulating (e.g. paper) strip between them and are then cut through together to out off a predetermined length of the foils for the purpose of forming an individual capacitor, the foils are provided with perforations 15, 16 at line of severance, the perforations being so shaped and positioned that at no point across the width of the foils along the line of severance does there occur more than one thickness of electrode strip. This ensures that the exposed cut ends of the foil after severance are separated from each other and short-circuits cannot occur. In the arrangement illustrated the anode strip 10 consists of aluminium-sprayed gauze and the cathode strip 13 consists of etched aluminium foil, these being separated by absorbent paper strips 11, 12. As shown, the perforations 15, 16 are circular: they may alternatively be in the form of slots which extend either parallel to or transverse to the length of the foils.

Gyroscope testing apparatus comprises a gimbal ring 34, Fig. 1, adapted to, receive the gyroscope to be tested, the gimbal 34 being pivoted by stub shafts and ball or roller bearings 33, Fig. 2, within a cage 23 which is itself pivoted by trunnions 21, 22, in bearings 20 on a pair of pillars 18, 19 rising from a table 12. The table 12 may rotate, as shown, about a vertical pivot pin 13, or, in a modification, the trunnions 21, 22, are pivoted in bearing in a yoke which is rotated about an axis parallel to the earth's axis at the rate of one complete revolution per siderial day in the opposite direction to that of the earth to eliminate the effect of the earth's rotation. Fine adjustment devices are provided for rotation about the various axes, means such as 62 being provided to allow them to be disengaged. Circular scales 15, 24 are read by microscopes 16,25 respectively whilst scale 36 is associated with light source 41, half silvered prism 38, double prism 39 and microscope 37 for direct reading, and light source 41, prisms 38,39,42,43, 44, objectives 45, 46 and photo-electric cell 40 for automatically reading or recording the angular position of gimbal 34 with respect to cage 23. The graduations on scale 36 may be formed as transparent markings on an opaque background and the photo-cell 40 provides a signal, such as at each minute of arc movement, when the image of the transparent marking on one side of the circle coincides with a transparent mark on the diametrically opposite side. Instead of the gimbal 34 being rotated by hand a servomotor mounted on end plate 29 of cage 23 may drive the rim of a disc 56 mounted on the upper end of the gimbal 34. Various tests which can be made on a gyroscope and the associated electrical circuits are described in the Specification.
