Title: A method of Forming Welding Studs
Inventor: GONZALEZ RICARDO
IPC: F16B37/04
Filed: 1968-12-12
Abstract: 1,194,449. Making welding studs; coining; welding by pressure. OMARK INDUSTRIES Inc. 12 Dec., 1968 No. 59233/68. Headings B3A, B3H and B3R. [Also in Division F2] A method of forming a welding stud comprises drawing a flat piece of metal 20 to form a cup 28 having an end wall and coining the end wall to cause metal to flow outwardly to form a sharp peripheral edge. A disc-shaped blank 22 is cut by a punch and die 23 and 24 except for carrying webs 25. The central portion of the blank is then drawn by opposed dies 26 and 27 into the cup 28 with a flange 13. A punch and die 32 and 34 completes the drawing process and also coins the drawn cup causing the metal in the bottom of the stud to flow outwardly giving a frusto-conical base 16 with a sharp corner 17. An air ejector passage 39 is provided for detaching the stud from the punch 32. Finally the formed stud 10 is cut completely from the blank 22 by a punch and die 43 and 44 to leave an annular trim 45 in the strip. In one embodiment the inside walls of the stud have threads 52 (see Fig. 4). In a second embodiment the stud 56 is bent to form arms 58 and a nut 59 locked therein (see Fig. 5). In a third embodiment the stud 61 is initially formed of round stock material, one end 62 of which has been flattened to provide a wide weld base area (see Fig. 6).

Title: Shoe Making Machine
Inventor: KAMBORIAN JACOB SIMON
IPC: A43D21/12
Filed: 1968-12-13
Abstract: 1,185,760. Boots &c. J. S. KAMBORIAN. 13 Dec., 1968 [14 Dec., 1967], No. 59392/68. Heading A3B. The lasting machine described in Specification No. 1,133,560 is provided with a modified toe conforming yoke 152. The yoke consists of a band 166 of p.t.f.e. on a spring-like backing member 158 which urges the legs 156 of the yoke 152 inwardly. The bight of the yoke (Fig. 9) is adjustably mounted on a bracket 164 which is connected by a pin 240 to a piston 234 in a bore 236. With the yoke 152 in its operative position the piston 234 abuts a resilient spacer 246. The forward ends of the legs 156 of the yoke are pivoted by pins 214 to links 212 whose other ends are pivoted by pins 210 to drive bars 168. The links 212 have shoulders 218 which abut the drive bars 168 to limit the pivotal movement of the links 212 about the pins 210. The drive bars 168 are pivoted to bell cranks 180 which are also connected to the piston rods 180 of air motors 186. The bars 168 are urged forwardly by cam followers 226 carried by pistons 222, 224. In operation the yoke is positioned above the shoe assembly with the inner edge of the yoke overlapping the outer edge of the shoe assembly so that when the shoe assembly is raised the yoke performs a downwiping operation on the shoe. When the shoe assembly has been raised to the correct height with respect to the wipers (not shown) the air motors 186 are operated to move the drive bars 168 inwardly to clamp the yoke against the shoe assembly. The resilient spacer 246 (Fig. 9) allows forward movement of the bight of the yoke during the clamping operation. When lasting moccasins and other shoe uppers having a similar ridged seam the yoke is retracted to an inoperative position during the rise of the shoe assembly by supplying compressed air through a fitting 248 into the bore 236 to move the piston 234 and hence the bight of the yoke rearwardly. The air pressure is also sufficient to overcome the forward force exerted by the pistons 222, 224 thus allowing the legs 156 to move rearwardly. The machine also includes heaters 300 which are resiliently mounted on brackets 302 and which are pressed against the wipers (not shown) when they are in their retracted position.

A golf club handle is constructed by providing a hand grip 14 whose interior configuration generally mates with the exterior configuration of the handle portion 12 of a golf club shaft 10, and bonding means bonding the hand grip 14 directly to the handle portion 12. In the preferred embodiment both the hand grip interior and the handle portion exterior are generally circular cylindrical, but it is also possible that the handle portion may be tapered and the grip interior shaped accordingly (Fig. 4, not shown). The exterior of the hand grip 14 preferably has a tapered or frusto-conical configuration. The open end 18 of the grip 14 may be slightly inturned to grip the shaft 10 in the area of the reduced reduced shoulder 20. A vent 22 is formed in the closed end of the grip 14 to permit the escape of air trapped during assembly. The shaft 10 may be formed of metal, wood or plastics, and the hand grip 14 may be moulded of a suitable rubber or plastics material or leather. In the preferred embodiment, the handle portion 12 is provided with a bonding material 24 which acts as a lubricant whilst the grip 14 is being assembled on to the handle portion 12 and then sets securely. Alternatively, the securement of the grip 14 to the handle 12 may be accomplished by activating the material either of the interior of the grip 14 or by the handle 12 by means of a suitable solvent, so that a bond is formed upon contact. If the bonding material 24 does not possess lubricating properties, the grip 14 may be expanded by mechanical or heat means to facilitate assembly.

Abstract: 1292553 Photo-electric sorting AMERICAN CYANAMID CO 31 Dec 1970 [9 Feb 1970] 62080/70 Heading G1A A device for identifying and sorting in ambient light articles 1 marked with luminescent material 3, whereby an ultraviolet light source 6 pulsating at a predetermined pulse frequency is directed at the articles the resulting radiation being received by a photo-detector 7 whose output is fed to an amplifier and control circuit (8), Fig. 2 (not shown) adapted to discriminate between pulse frequencies of the ultraviolet light source and other ambient frequencies in order to generate a control signal to sort and identify said articles on the basis of the presence or absence of the luminescent material. The pulsating frequency of the ultraviolet light source is chosen to be different from any pulsating frequency present in the ambient light. Furthermore by employing narrow band width luminescent material and using optical filters the device can be adapted to distinguish between articles labelled with different luminescent materials. In one embodiment Fig. 3 (not shown), in which the articles are moved on a conveyor belt, the control signal is utilized to activate a plunger solenoid which pushes the article into an "accept" chute. In a further embodiment similar to above Fig. 4, two sets of pulsating ultraviolet sources 26 and 28 and detectors 27 and 29 are placed as shown. The sources 26 and 28 pulse at different frequencies from one another, and each detector has a filter which only passes the pulse frequency of its corresponding light source. Thus any possibility of the light from a lamp on one side of conveyor belt 25 affecting the detector amplifier on the other side is eliminated.
