Abstract: 1280250 Feeding webs RICOH KK 3 Dec 1970 [16 Dec 1969] 57410/70 Heading B8R An electrophotographic copying machine 6, 7, 10 is fed with copy paper from a roll 1, the paper passing into the machine by way of feed rollers 3 and a cutter 4 which are electrically controlled so as to cause the paper to be severed in equal portions of predetermined length; a photo-electric sensing arrangement 11-14 senses the presence or absence of the paper at a predetermined position A which is so located that when the arrangement senses the passage of the trailing end of the copy paper past the position A it provides a signal indicating that the remaining paper is of sufficient length for obtaining only one more portion of said predetermined length, said signal being operative to halt operation of the cutter 4 so that the said remaining paper can pass through the cutter uncut. Thus the possibility of jamming the machine by feeding through a sheet of paper less than the required predetermined length is avoided. Warning means, e.g. a lamp or buzzer associated with the sensing arrangement, indicating the absence of paper at point A may be provided. A suitable circuit arrangement for the control and sensing system is described with reference to Fig. 2 (not shown).

Abstract: 1295500 Rolling gears TELEDYNE Inc 21 Dec 1970 60690/70 Heading B3M Apparatus for roll-forming a pre-hobbed gear-wheel W comprises a rotatable tool 54 on one side of the gear-wheel and supporting rollers 34 and 36 on the opposite side, the rollers bearing on discs 96 and 98 between which the gearwheel is clamped. The disc 96 is formed with a central spigot which passes through the gearwheel (Fig. 2, not shown) and co-operates with the disc 98. By moving the disc 98 longitudinally the gear-wheel is unclamped. The two discs are mounted on a carriage 56 which'is horizontally movable so that the discs can be shifted between a rolling position and a feeding position. To start rolling, the carriage is moved to the left, Fig. 3, and a blank is raised by a fluidpressure ram 120 to a position between the discs 96 and 98. Further blanks are prevented from moving by a roller 120 associated with the carriage 56. The carriage then moves the clamped blank between the tool and the rollers 34 and 36. The rollers can either be retracted to allow location of the workpiece in a rolling position, and then be raised to exert the rolling force, or the rollers can be held in position and the workpiece be drawn slowly between them. A safety device can be used to stop the machine if a faulty blank causes a delay in the feeding procedure. A shoot 126 guides finished blanks away from the apparatus. The carriage 56 may be mounted on stiff springs to accommodate slight vertical movements of the gear-wheel.

Title: Method and apparatus for generating stable coherent pulses of optical radiation
IPC: H01S3/082
Filed: 1968-12-23
Abstract: 1,255,807. Lasers. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP. 23 Dec., 1968 [25 Dec., 1967], No. 61087/68. Heading H1C. A laser produces a train of pulses having a repetition frequency which is a multiple p of the axial mode separation C/2L, the pulse train being produced as a result of (a) an auxiliary resonator, and (b) modulation of the optical emission within the resonator at a frequency corresponding to the repetition frequency. In one arrangement, Fig. 2, an He-Ne gas discharge tube 7 is located in a primary resonator formed by mirrors 2, 21, and the optical path length is disturbed periodically at the repetition frequency by an electrooptic crystal 8 excited by a modulating signal source 16. The auxiliary resonator is formed by mirrors 21 and 15 which are coupled by a beam splitter 12 of low reflectivity, the auxiliary resonator causing the Q factor of the primary resonator to vary periodically within the band width of the emitted radiation. The auxiliary resonator is arranged so that its optical path length is 1/p of the optical path length of the main resonator. An alternative arrangement, Fig. 7, uses a YAG laser rod 17 which is pumped by tungsten lamp 20, the rod and lamp being located at respective foci of an elliptical reflector 21. A duct is formed by a quartz tube 19 for circulated cooling water. The resonator is defined by mirrors 2, 25 of which mirror 2 is axially displaceable by a hollow cylinder of piezo-electric material 34, while mirror 25 is formed on part of a fused quartz block 24 which incorporates the beam splitter and the auxiliary resonator reflector 26. Phase modulation is effected by a crystal 8, e.g. LiTaO 3 , which is housed in a microwave resonator 27 and is energized by a modulating signal source 16. The oscillatory mode is stabilized by using a photo-detector 30 in the laser output path and passing the detector output through a narrow band-pass filter 31 where it is compared with the modulating signal in a phase-sensitive detector 32. Any deviation detected by the phase detector is amplified at 33 and is applied to the piezo-electric cylinder 34 to axially adjust the mirror 2. An interferometer of the Michelson type is used in Fig. 8 and comprises quartz components 35, 36 with their boundary surfaces coupled by a dielectric film 37 to form the low reflectivity beam splitter. Use of a beam splitter is avoided in Fig. 9 by providing a fused quartz block 40 in the laser optical path, the block having polished end surfaces with one end 41 coated with reflecting material to form the resonator mirror. A ring laser is also described, Fig. 10, which comprises four laser active media 17 and corner reflecting mirrors 43-46 forming a closed optical path including a modulator 8. Mirror 46 is slightly transmissive and couples a second ring optical path formed by mirrors 47-49 to the primary ring, the second ring path length being 1/p of the primary ring path length.

[Also in Division B2] A suede-like material is produced by applying a layer of a polyurethane elastomer solution to a support, coagulating the polyurethane solution by treatment with a coagulating bath to form a polymeric layer having a relatively large spongy structure in the inner part thereof, bonding a first substrate to the surface of the polymer layer by means of an adhesive, peeling off the support from the polymer layer, bonding a second substrate to the surface of the polymer layer exposed by peeling off the support by means of an adhesive, and tearing the polymeric layer in two along a plane extending through the centre of the layer by pulling the substrates apart. The support may be a glass or metal plate, or a synthetic polymer, e.g. nylon, polyester, polyethylene, polyvinyl alcohol or a derivative thereof. The polymer solution may comprise mixtures of polyurethanes and other polymers, e.g. polyvinyl chloride, polyacrylic esters, polyvinylidene chloride, poly-alphamethyl styrene, polyamides, polyester amides, polyesters, polybutadiene and copolymers of butadiene and acrylonitrile can be used in admixture with polyurethane elastomer. Pigments, dyestuffs, fillers and plasticizers may be included in the polymer solution. The coagulating bath may be made of a liquid which is at least partially miscible in the solvent for the polymer but which is not a solvent for the polymer, or a mixture of a solvent for the polymer and a non-solvent for the polymer. Suitable substrates are woven fabrics, knitted fabrics, non- woven fabrics and such fabrics finished with resins. The adhesive may be a two-part type polyurethane adhesive, a substantially linear, one-part type polyurethane adhesive, a mixture of polyvinyl acetate and a polyacrylate or a self-cross-linkable nitrile-butadiene rubber applied in the form of a solution or dispersion by spraying,brushing, roller coating orknife coating. The polymeric layer may be torn into two by hand or preferably by pulling the substrates in the opposite direction by the rotation of rollers. Prior to applying the polymer solution, there may be applied to the support a solution or dispersion which may also contain polymer of a coagulation regulator which is capable of making a polymeric layer having a microporous structure. Suitable coagulation regulators include hydrocarbons, carboxylic acids, carboxylates, amides, nitriles, sulphonates, ureides or urethanes which contain an alkyl group having from 4 to 50 carbon atoms. A coagulation regulator such as an alkyl alcohol having an alkyl group containing from 4 to 50 carbon atoms may also be added to the polymer solution to give the inner part of the polymeric. layer a macroporous structure. The products are suitable for clothes, bags, shoe uppers and cloth for lining furniture.
