Filed: 1973-04-24
Abstract: 1434059 Welding by pressure SIEMENS AG 24 April 1973 [24 April 1972] 19447/73 Heading B3R [Also in Division H2] In electric resistance welding an insulated metal wire 2 to an uninsulated metal member the wire is placed on the member and an electrode 3 having a cutting edge 4 is moved towards the member to sever the wire and complete a circuit for welding current through the electrode and member, current thus flowing to remove the insulation and to soften the member and wire by resistance heating and the wire being pressed into the member. In an embodiment an electrode 3, e.g. of tungsten, has its knife edge 4 defined by an inclined face 6 and a face of the electrode parallel to the longitudinal axis and is held by guide means for vertical movement. An enamelled copper wire 2 is supported, below the electrode, on a copper alloy connecting lug 1 and the electrode is lowered so that the edge 4 severs a portion 5 of the wire 2 and engages the lug 1. Current then passes between the electrode 3 and the lug 1, the enamel on the wire 2 burns and current passes through the wire 2 resulting in a weld between the wire 2 and the lug 1. Coil terminal connections to connecting lugs in electromagnetic valves may be similarly welded.

Title: Improvements in or relating to a process for making reticles and reticles produced thereby
IPC: G02B27/32
Filed: 1945-07-31
Abstract: 597,964. Reticles. BUCKBEE-MEARS CO. July 31, 1945, No. 19678. Convention date, Aug. 5, 1943. [Classes 97 (i) and 98 (ii)] Reticles are formed from a metal blank by coating both faces thereof with light-sensitive material, photo-printing a plurality of designs for the reticles and the outlines thereof on each face of the coated blank with the designs and outlines on one face registering with those on the other face, developing said designs and outlines to form in said coatings openings conforming therewith and etching through these openings to form designs pervious to light on a plurality of opaque reticles. In one way of carrying out the process, photographic negatives 16, 17, Fig. 5, prepared from line drawings of the designs and outlines are superposed with the lines 19, 20 of the designs and outlines respectively in register. Between the negatives and stuck to the negative 17 as at 22 is placed a blank 21 as of copper, coated on both faces with a cold top enamel, the negatives being held fast by adhesive strips 18. The negatives are then exposed, the blank removed and the lines formed thereon developed. One face of the blank may now be coated with asphaltum and attached to a glass plate, while the other face is etched in a machine to a predetermined depth as by ferric chloride. The blank is now removed, the asphaltum removed and the other face etched until the blank is perforated along the outlines and designs of the reticles. In forming dish-shaped reticles, the procedure is the same until the etching step is reached. After etching part-way through one face of the coated blank, the designs are masked and the outlines of the reticles etched completely through the blank to form separate blanks. These blanks are shaped by a die and after removal therefrom are each. placed concave downwards on a glass plate, the space between the blank and the plate being filled with an acid resist, such as wax. The convex face is then etched completely through the lines forming the design of the reticle. In each case, when the reticles are formed they are placed in a cleaning solution such as trichlorethylene and then in a caustic solution followed by a water bath. The reticle surfaces may be oxidized to render them non-reflecting or highly reflecting surfaces may be provided by the deposition of a white metal, e.g. silver. Specification 581,337 is referred to.

Filed: 1926-10-23
Abstract: 277,922. Fitzpatrick, H. D., (U.S. Slicing Machine Co.). Oct. 23, 1926. Cutting slices in succession. - A disc knife reciprocating table slicing machine is characterized by the combination of a substantially conical slice receiver, positively rotated by means connected with the mechanism of the slicing machine, and a stationary slice deflector extending partly around the edge of the knife. As shown in the Figure, the slice receiver 36 is journaled on a shaft 15 fixed in a bracket 14 extending from the machine base 10. The receiver is driven from the main shaft 13 by a shaft 17 and bevel gearing, the hub 18 of the receiver being secured to the gear 16. The receiver has an upright peripheral edge to prevent the slices from being thrown off by centrifugal force, the edge extending under the reciprocating table 12. The gears are so proportioned that the receiver 36 makes one revolution for each cutting stroke of the table, a stack of slices being thus produced. The peripheral speed of the receiver is slightly greater than the linear speed of the table 12 so that the slices, as they fall, are slightly stretched and the formation of wrinkles is prevented. The slice deflector and the slicing machine are preferably as described in Specification 271,308. The support 31 for the edges of the slices is carried by a bracket 32. The gearing may be designed to form a number of stacks or to arrange the slices in an overlapping formation similar to that described in Specification 214,908.

Title: Improvements in and relating to the manufacture of soap-like materials
IPC: C11D1/14
Filed: 1933-07-14
Abstract: Soap-like materials which are unaffected by lime and magnesia and will lather with sea water are formed by mixing salts of the reaction products of sulphuric acid on saturated aliphatic alcohols containing more than 8 carbon atoms with similar salts of higher unsaturated fatty alcohols.  Instead of mixing the sulphonates, the alcohols may first be mixed and then sulphonated. Ordinary soaps may be added in an amount not exceeding 20 per cent together with disinfectants and scents and the soap-like materials can be shaped into ribbons, flakes, needles &c.  In an example, two parts of the sulphonates of the fatty alcohols obtained by the reduction of the acids of coconut or palm kernel oil are mixed with one part each of saturated and unsaturated fatty alcohol sulphonates having 16 or 18 carbon atoms. In a second example, 53 parts of a mixture of equal parts of olein alcohol sulphonate and a sulphonate of cetyl or octadecyl alcohol are mixed with 40 parts of lauric alcohol sulphonate and 7 parts of curd soap.

Title: Conveyor systems
IPC: B65G19/20
Filed: 1961-06-03
Abstract: 1,008,772. Conveyer systems. A. FREEMAN ENGINEERS Ltd., and A. FREEMAN. May 25, 1962 [June 3, 1961], No. 20103/61. Heading B7L. A conveyer system comprises a trackway 1 for the passage therealong of work carriers 2 and associated with this trackway and running in the same direction a fixed guideway formed by upstanding ribs 18, 19, along which runs a flexible elongated driving means of low friction material, the arrangement being such that the loaded carriers will have their centres of gravity vertically above or below the driving means and will be supported substantially only on the driving means. The trackway 1 is formed with a flat base 4 with a flange 5 at one side and turned over flange (not shown) at the other. The ribs 18, 19 are secured to the base 4. The driving means comprises a cable 20 with driving elements 21 secured at short intervals along it. The elements are made of a self-lubricating material, e.g. molybdenum disulphide or polytetrafluoroethylene, and are made so that they may be easily removed and replaced on the cable 20, on which they are held by welded collars 25, Fig. 5. The elements stand just proud of the ribs 18, 19 and engage with work carriers 2 on the trackway. The carriers 2 are formed as plate-like members with adjustable workpiece holders 12, e.g. for shoe lasts, secured thereon so that the weight is concentrated over the driving elements. The trackway 1 may be elevated and the carriers may have a suspended load arranged with its centre of gravity directly below the driving elements (Fig. 8, not shown). Each carrier has an upstanding wall 8 which at the forward end of the carrier supports a spindle 10 for a roller 9. The carriers may be arrested by ramps 30 which engage the rollers 9 and tilt the carriers about the ribs 18, thus disengaging the driving means. Each carrier has a ramp-like tail 31, which arrests a following trolley when stationary. The ramps 30 may be fixed or may be pivoted to the trackway to swing between operative and inoperative positions, or the ramp may be retractable out of the path of the rollers 9 under the action of control means (not shown.) To prevent slip when a carrier ascends a steep incline a catch element 33 is provided on the carrier which tilts to engage directly with the elements 21 through slots in the carrier. The driving elements 21 have rounded ends to enable them to roll on one another at bends in the trackway 1, and they may have laterally projecting flanges to engage with suitable guides at these bends to retain the elements in the guideway. The elements 21 may also have integral gear teeth at their sides to actuate control means for the conveyer system (Fig. 7, not shown) and several trackways 1 may be mounted one above the other. Specifications 733,419, 747,408, 779,127, 801,180, and 873,425 are referred to.
