Filed: 1970-11-24
Abstract: 1291162 Riveting OLYMPIC SCREW & RIVET CORP 24 Nov 1970 [24 Nov 1969] 55825/70 Heading B3U [Also in Division F2] A headed sleeve 13 of a blind rivet assembly is deformed by a setting pin 15 whose locking head 22 has a hard core 38 and a soft peripheral layer 39, the soft peripheral layer being drawn, during the riveting operation, toward the end of the locking head 22 so as to produce a radial outward force to form a shoulder 37 in the sleeve 13. The locking head 22 is initially hardened during its formation and the peripheral portion is subsequently annealed by heating, using a high frequency induction heater, and cooling rapidly. In operation the sleeve is inserted in holes 18 and 19 of the plates, Fig. 3, and the end 17 of the setting pin 15 pulled by device 20. A hardened shoulder 29 of the setting pin sets up an expansion wave as it is drawn into the sleeve 13 so that the plates 11 and 12 are clinched together and the sleeve expanded into tight engagement with the plates. As the locking head 22 is pulled into the sleeve 13, a taper 22a is gradually drawn into a flare 22d, Fig. 6, due to the deformation of the soft peripheral layer 39, and the shoulder 37 formed against the plate 12. At this point the shoulder 29 abuts a shoulder 32 in the sleeve and, on continued pulling of pin 15, a locking crown 24 is swaged into a locking groove 25 in the setting pin together with the breaking of the setting pin at groove 28. In other embodiments a weakening recess is formed in the end face of the locking head, either with or without an inturned flange around the outer portion of the recess.

Title: Catcher mechanism for the laying of quilting material
IPC: A41H43/00
Filed: 1971-12-01
Abstract: 1299809 Laying fabrics CUTTERS MACHINE CO Inc 1 Dec 1971 [20 Jan 1971] 55860/ 71 Heading D1S A catcher mechanism 20 for a machine for laying fabric 16, e.g. quilting material, comprises vertically movable upper and lower catcher bars 27, 37 both mounted on a standard 21. A laying carriage 10 having a laying mechanism 11 reciprocates on wheels 12 over a table 13. The catcher mechanism includes a pair of standards 21 each having vertical tracks 23, 24. The upper catcher bar 27 is supported by arms 26 supported by roller bearings 25 riding in the tracks 23 and carriers cams 28 for engagement by followers 29 on the mechanism 11. A shaft 30 is journalled through the arms 26 and carries, on its ends, sprockets 31 engaging sprocket chain racks 32 on the standards 21. The lower bar 37 is free to reciprocate vertically between the table 13 and the bar 27 and is supported by arms 36 supported by bearing blocks 35 having roller bearings 34 riding in the tracks 24. Each block 35 has a hook 45 to which a loop attachment 44 on a cable 43 is connected. The opposite end of the cable 43 is fixed to a shaft 41 of a windlass 40. Manual rotation of the shaft 41 raises or lowers the bar 37 which may be locked in an elevated position by the engagement of a pawl 49 pivoted to a fixed bracket 50 with a ratchet 48 on the shaft 41. The bar 27 may be locked in an elevated position when the stack has been laid by the automatic engagement of a spring pressed plunger 53 on the arm 26 in a hole 52 in the track 23. In operation, after a few layers have been laid, the bar 27 rests on top of the folded ends of the stock 16 and the bar 37 rests below the stack on the table 13. For quilting fabric, the bar 27 crushes the folded fabric and sinks into the fabric whilst the mechanism 11 continues to rise in accordance with the number of layers laid. Eventually the mechanism 11 rises so high that there is no engagement between the cams 28 and the followers 29 so that the bar 27 ceases to function. The operator rotates the shaft 41 to raise the bar 37 to compress the folded ends of the quilting fabric and the bar is locked in this raised position so that the cams 28 and the followers 29 re-engage. This is repeated periodically.

Title: Improvements in and relating to the manufacture or cellular products of thermosetting resins
IPC: C08L61/10
Filed: 1969-11-18
Abstract: 1280680 Continuous production of thermo-setting foam. COMPAGNIE DE SAINT-GOBAIN 18 Nov 1969 [29 Nov 1968] 56391/69 Heading B5A [Also in Division C3] Cellular products of thermosetting resin are continuously manufactured by uniformly distributing resin with blowing agent and catalyst over a lower conveyer, allowing the resin to expand as it is carried by the lower conveyer, containing the foamed resin between the lower conveyer and an upper conveyer, heating the upper and lower surfaces of the web so as to form hardened surface layers and drying and/or removing volatile substances from the resin. Each conveyer is preferably covered with an intermediate conveyer which has a smooth surface and may comprise a glass fibre fabric impregnated or covered with polytetrafluoroethylene. As shown, the mixture of resin (preferably phenolic), blowing agent and catalyst is supplied from reciprocating nozzle 1 in a uniform layer on the lower intermediate conveyer 2 which covers lower conveyer 6. The resin foams and is then brought into contact with upper intermediate conveyer 9 which covers upper conveyer 12. Hardening of the resin and formation of hardened surface layers is completed by heaters 19, 20 and the resin layer is separated from the conveyers, resin particles being removed from the conveyers by brushes 22, 23. The resin is then completely dried with optional cutting into panels before drying. The belts are preferably preheated by infra-red radiant tubes 3, 14 and 15 to about 40 C. and infra-red radiant tubes 19, 20 are also used at the ends of the main conveyers. The final drying is preferably performed using ultra-high frequency radiation. When a phenolic resin is used, it preferably contains a surface active silicone oil and CCl 3 F or CCl 2 F-CClF 2  or a mixture thereof as blowing agent. Organic nitrogen compounds which are decomposed by heat, releasing a gas which does not support combustion may be added to the resin alone or mixed with an acid catalyst. Resorcinol may also be added to reduce the amount of acid needed for the exothermic reaction that initiates foaming.

Title: Photographic type face reproducers
IPC: G03F1/00
Filed: 1971-12-09
Abstract: 1381102 Phototypsetting LINOTYPE PAUL Ltd 25 Oct 1972 [9 Dec 1971] 57421/71 Heading H4F The image of a selected character on a rotating transparent drum C, Fig. 1, is projected using light source LS on to a vertical array of photodiodes PDA, the character being horizontally scanned by movement of the drum and vertically scanned by sequential switching of the diodes. The start of a sequence of characters is detected by detector SC when double line DS passes in front of detector SC. The beginning of a new character space is similarly detected using the passage of the shown boundary lines. A detector DF detects clock pulse lines G for synchronizing the circuit operations. In the processing circuit, Fig. 3, the code number CR of a desired character is set in a code request store CRS, and the number NL of vertical scans needed to scan the character is set in a count-down counter LPC. The sequence start double pulse DS is detected at PDP and resets a character counter CCT. Each boundary line output of detector SC increases the count in counter CCT until, as determined by a coincidence detector CD, the character count reaches the code number stored at CRS. The resulting pulse from the coincidence detector acts on flip/flop SFF1, and so primes AND gate AG1. The pulses from detector DF are fed by a frequency divider FD to give pulses defining each scan line. The first such pulse after the setting of SFF1 passes through gate AG1, to set flip-flop SFF2, the output of which primes diode array drive AND gate AG2. Drive pulses at 10 Mc/s from generator OS pass through the gate and sequentially enable the diode samplers SS, to give a successsion of output video signals VO. The drive pulses are counted in counter FDC and when a count is reached indicating that the scan is finished, AND gate AG3 produces a signal which, via one shot OS4, resets flip-flop SFF2 and disables AND gate AG2. This AND gate remains disabled until the next scan defining pulse is produced by the divider FD. The can proceeds, with each end of scan signal from gate AG3 decreasing the count of counter LPC by one, until said count reaches zero, whereupon AND gate AG4 resets flip-flop SFF1, and stops the scanning. The video signals VO are converted to binary form by threshold and limiter, TCL flip-flop VFF and one shots OS1, OS2 and are converted from serial to parallel format by AND gates AGS feeding the count in counter FDC into a digital store DM. The digital store DM eventually stores the entire character for readout, e.g. by CRT. Various methods of increasing the character selection rate are described, e.g. using a plurality of scanners spaced round the drum, or having a plurality of characters C1-C4, Fig. 4, with respective scanners LS1-LS4 arranged axially on the drum.
