Title: Improvements in work-holding fixtures of vice form
IPC: B25B1/08
Filed: 1945-03-22
Abstract: 580,874. Vices. REAY, H. March 22, 1945, No. 7264. [Class 61 (ii)] In a vice, having a small travel, arrangement is made for the travel to be increased without turning the screw, by moving a pivoted plate against which the screw normally bears. The vice consists of a fixed jaw 4 having a base 1 and a movable jaw 5 slidable on a seating 6 on the base 1. Interchangeable pairs of pads 7 and 8 are secured to the jaws by dowels. A pair of guide rods 11 and 11a pass through bushed holes 12 in the fixed jaw and are connected to the movable jaw 5. The opposite ends of the guide rods are connected by a yoke 14 carrying a clamping screw 15. Pivotally mounted on the guide rod 11 is a sidewardly extending lever 16, constituting a spacing member, formed with a gap 17 in which the other guide rod 11a fits. The lever 16 lies hard against the back of the fixed jaw 4 and is thus interposed between the fixed jaw and the clamping screw 15. A hardened steel button 18 is mounted on the lever to contact with the end of the clamping screw. As an alternative to the pivoted member 16 a slidable spacer may be used. When an extensive movement of the jaws 4 and 5 is required the lever 16 or other spacing member is moved, so that normal clearance between the end of the clamping screw 15 and the position of the abutment face is increased, by the thickness of the spacing member. Spring plungers may be used to separate the jaws when the clamping pressure is removed.

Title: Improvements in or relating to apparatus for and method of making hollow plastic articles
IPC: B29C49/04
Filed: 1957-03-06
Abstract: 818,904. Blow moulding hollow plastic articles. PLAX CORPORATION. March 6, 1957 [April 18, 1956], No. 7431/57. Class 87(2). Individual moulds M are moved successively to a charging station to receive lengths of tubing P of softened organic plastic material continuously extruded from the nozzle 20, the nozzle then being moved away from each charged mould faster than and in the opposite direction to the extrusion of the material from the nozzle, and the length of plastic in each mould is blow moulded. The extruder E is pivotally mounted on horizontal trunnion pins 9 to provide for up-and-down pivotal movement of the head H of the extruder. This movement is effected bv a fluid motor 11 which is operated by an hydraulic pressure medium supplied at intervals from the timer T. In the machine shown, four of the moulds M are mounted on a rotating carrier C and each is successively positioned beneath the nozzle 20 to receive a length of the tubular plastic P which is severed by means of a knife 62 reciprocated by an air motor 63. Each shearing operation of the knife is effected simultaneously with the raising of the extruder head H, by the motor 11, at a rate which is at least slightly more rapid than the rate of extrusion of the plastic from the nozzle so that the severed ends of the plastic are drawn out of contact. The head H is raised high enough for the mould which is about to receive a charge to be movable to the charging station without contacting the plastic P. Air or other suitable pressure fluid is discharged from the blow head 73 into the tubular plastic charge in the mould, the various moulds being located successively at the extruding and blowing positions and opened and closed when necessary as the carrier C advances. A complete mould cycle involves a full revolution of the mould carrier C, and for each quarter turn of the carrier the extruder E and associated parts go through a complete cycle of operation in co-operative relation with one of the moulds M on the carrier.

Abstract: 829,344. Rejection circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 6, 1957 [March 6, 1956], No. 7499/57. Class 40 (8). A wavetrap in a power-transmission line for isolating switchgear &c. from high - frequency telecommunication channels using the same line, comprises an inductance divided by tapping points, each part of the inductance being tuned by a separate network to one of the h.f. channels, the mutual inductance between the separate parts being compensated by additional inductance elements. In a two-channel system, Fig. 2a, an inductance is connected in series with the power line AB and is divided into two portions L1, L2 at a tapping point C. The mutual inductance M between the two parts L1, L2 is compensated by connecting an inductance of value M to the point C, thus enabling the resultant inductances L<1>1 =L1 +M and L12=L2+M to be tuned by circuits N1, N2 independently of each other. The single compensating inductance M may be replaced by an auto-transformer having a transformation ratio of 1 : 1 (Fig. 3, not shown). In the threechannel system of Fig. 4a, two of the compensating inductances M12, M23 are in the form of simple inductors whilst the third element M13 is in form of a 1 : 1 transformer. The inductances are tuned to the three channels by networks N1, N2, N3. In a modification (Fig. 5, not shown), the main inductance is shunted by a further inductance which is tapped at the appropriate intervals. In the arrangement of Fig. 6, both the main inductance and the shunting inductance are tapped and two compensating inductors M12, M<1>34 used to provide a three-channel wavetrap. The main inductance may be divided into several parallel inductors having mutual inductance between them. Only one of these need be tapped. The compensating networks N may be purely reactive or may contain resistances.
