Title: Apparatus for continuously manufacturing synthetic expanded plastics material sheaths and section members
IPC: B29C53/38
Filed: 1968-03-09
Abstract: Apparatus for continuously manufacturing sheaths and section members of expanded synthetic plastics material coated with a sheet material on the outside comprises an elongated outer tubular member 1 consisting of two halfcylinders mounted in a frame 2, reels such as 10 and 11 and 14, 15 and 16 (not shown) supplying coating film 12 to the inside of the tubular member 1, two injectors 20 and 21 for injecting the components required to form a rigid polyurethane foam into the annular space 6 in tubular member 1, and driving means generating a continuous longitudinal sliding movement between the tubular member 1 and the coating material 12 containing the polyurethane foam. The former 3 which may be a temporary or permanent framework slides freely inside the tubular member 1 and moves forward as the foaming material is delivered on to it by the injectors 20 and 21. As the coating film 12 is supplied its selvedges are joined to form a tubular member by welding, adhesion or by means of a sliding fastener having a slider connected to the tubular member 1. The driving means comprises a motor and four bi-conical rollers two of which 52 and 53 are supporting driven rollers and two of which 54 and 55 are guide rollers. Arms such as 524 and 544 connected to rollers 52 and 54 are connected to the same stirrup 56 biased by an adjustable spring 57. Diameter selectors such as 543 regulate the force with which the rollers grip the pipe. The machine may be used in the field for laying pipes directly into trenches.

Title: A conjugate staple fiber having an improved spinnability and method for producing same
IPC: D02G3/24
Filed: 1968-06-01
Abstract: A crimped conjugate staple fibre having an improved spinnability, wherein at least two different synthetic polymers are bonded in an eccentric relation to each other along the fibre axis, is chatacterized in that the length (L), free length (F), number of crimps (N 0 ) and fineness (d) of said fibres satisfy simultaneously all of the following four formul[mu]:- The ratio F/L is the free length ratio, where F is the maximum length of one of the staple fibres when it is mounted on a smooth plane under no tension and no mutual restriction between the fibres, and L is the fibre length when a load of 1 mg./denier is applied N 0 is the number of pitches/25 mm. of staple fibre. The staple fibres are made by feeding a tow composed of crimpable conjugate filaments into a liquid at a temperature of at least 70 C., e.g. boiling water or glycerine at 70 to 100 C., at a constant rate to develop crimps latent in the filament, removing the crimped tow at a lower rate than the feeding rate so that the tow proceeds under a tension of about 1 mg./denier, squeezing the tow, which is then dried and cut. The two different synthetic polymers may be a homopolyamide and a copolyamide such as poly-#-capramide and a copolymer of #-caprolactam and hexamethylene-diammonium isophthalate or terephthalate a homopolyester and a homopolyester ether such as polyethylene terephthalate and polyethylene paroxybenzoate polypropylenes having different intrinsic viscosities.

Patent ES-361058-A1 (ES)
Title: A device suitable for charging a storage battery from an alternating power source
IPC: H02J7/02
Filed: 1968-12-04
Abstract: Battery-charging circuit comprises an A.C. source, an impedance which limits the charging current, and a controlled rectifier, the firing angle of which is regulated in accordance with the battery voltage. In the circuit shown in Fig. 1, the battery B is charged from a mains transformer Tr by way of a limiting inductance L1, a rectifier bridge Rd, and a thyristor Th. The firing of the thyristor is controlled by a synchronized power supply system comprising transistors T10 and T11, and a pulse generator including transistors T2 and T3 and a capacitor C1 The emitter of transistor T10 is held at a fixed voltage derived from a secondary winding S1 of the transformer Tr, and when the output of the bridge Rd reaches a preset value each half-cycle, the transistor T10 is biased on and in turn switches on the transistor T11. This applies a steady voltage to the transistor T2 which charges up capacitor C1 until a unijunction transistor T1 breaks down, whereupon the capacitor discharges and applies a firing pulse to the gate of thyristor Th. A train of such pulses will be supplied during the period that transistors T10, T11 are conducting. The firing angle of the thyristor, i.e. the delay before the arrival of the first pulse, is determined by the rate of charging of capacitor C1, controlled in turn by the biasing of transistors T2 and T3. A voltage representative of the battery voltage is derived from a potential divider R8-R12, and this is compared with a reference voltage from a Zener diode Dz3 by transistor T3 in such a way that the firing delay varies inversely with the battery voltage. Temperature dependent resistors CTN, CTP, having respectively negative and positive temperature coefficients, regulate the charging current according to the battery temperature. Auxiliary devices, Figs. 3 and 4 (not shown), may be connected to the circuit of Fig. 1, and comprise means for automatically charging the battery more rapidly after mains failure. During any period of such failure, a secondary accumulator is charged by the battery B, and its subsequent discharge raises the main charging rate. A further device for increasing the charging rate when the battery voltage has dropped substantially due to heavy loading may also be connected.

Title: Fast Rewind of Tape in Recording and/or Playback Apparatus
IPC: G11B15/10
Filed: 1979-06-25
Abstract: When a manual actuator S4 moves between "normal" and "fast rewind" positions, in addition to lifting the pressure roller from the capstan, it briefly earths a monostable multivibrator 3 and hence causes a pulse to be delivered to relay R1 which reverses the direction of tape motion. When moving between "normal" and "fast forward" the line 2A is not earthed. Closing switch S3 also reverses the direction of tape movement. Automatic reversal of tape movement at each end of the tape is described also: a detector 1 senses the motion or otherwise of tape reel support 20 and hence causes a pulse to be delivered to the reversing relay R1 through logic break 2.
