The blade 3, Fig. 1, is secured in ahead 2 formed on a handle 1 and the anvil 7 is formed integrally with a reed 5 also secured to the handle. A recess 10 is formed on the anvil such that as the reed is vibrated by an electrical drive unit, e.g. a vibrator or exciter 6, to effect shearing of a hair 9, the edge 8 on the anvil does not contact the cutting edge of the blade; the drive unit may be connected to an A.C. mains supply via wires passing through the handle. In a modification, Fig. 2 (not shown), the head (12) is formed with a guard surface 15, 16, the reed (19) extending through an opening (18) in the guard. A resilient stop (22), Fig. 3 (not shown), for abutment by the reed during reciprocation may be provided. In an alternative arrangement, the blade may be mounted for vibration while the anvil remains stationary. In the construction shown in Fig. 4, a pair of blades 24, 25 are mounted on a tuning-fork 26 arranged to be vibrated at its resonant frequency by an electric device 27; the second blade constitutes the anvil.

Title: Improvements in or relating to the manufacture of concrete elements
IPC: B28B7/28

Abstract: 1,207,190. Moulding concrete. DANSK SPAENDBETON A.S. 8 Dec., 1967 [9 Dec., 1966], No. 55931/67. Heading B5A. In casting concrete elements in a mould provided with parallel cores which are withdrawn from the partially set concrete one, or a few, at a time, those cores which are, at any instant, not being withdrawn absorb the reaction of the force necessary to withdraw the said one or few cores. An elongated mould 1, 2 has longitudinally extending cores 3 connected by rods 5 to pistons 4 of an assembly of hydraulic cylinders A-G carried by a wheeled structure mounted on the mould. The rear ends of the cylinders are interconnected by a pipe 6 and the front ends are connected by pipes 7 to a fluid distribution valve 8 supplied with fluid from a tank 11 by a pump 9. A return pipe 13, and a by-pass valve 14 and pipe 15 are provided. In the position of the cores shown, the valve 8 is operated, e.g. by a driven cam-shaft, to direct fluid to cylinder D via pipe 7, while for the other cylinders unobstructed passage exists through the other pipes 7 and valve 8 for fluid to return to the tank. Thus, the piston in cylinder D and its associated core is moved longitudinally and transfer of fluid from this cylinder to the others via pipe 6 produces a force on the rear of the other pistons and, since the cores associated therewith are held in the concrete, the assembly of cylinders is moved a further distance producing an additional advance of the said associated core. By feeding pressure fluid to different cylinders, in turn, the cores are withdrawn in stages from the cast concrete.

The pad assemblies 27, 29 are mounted on pins 36 having heads 37 which lie adjacent a flange 38 integral with caliper body 11 and split pins 39 secure the pins 36 in place. As shown, the bridge piece 12 acts on the pad assembly 29 via a back-up plate 33 which is welded to a straight central portion 34 of the bridge piece 12 and the side edges 35 of the plate 33 are bent up so that drag forces from the pad assembly 29 are transferred to the bridge piece 12: the pins 36 pass through bores in back up plate 33. Alternatively the central portion 34 of the bridge piece 12 can be deformed to receive a backplate 28 of pad assembly 29 thereby dispensing with the plate 33. The torque plate 14 slidably receives the pad assembly 27. The bridge piece 12 is secured to ears 31 integral with the body 11 by bolts 30, but rivets or other means may be used. Portions 40 of the limbs 32 of bridge piece 12 are shown deformed by means of a concave flattening (41). The arrangement minimizes the radial gap which must be left between the disc and a wheel when the disc brake is mounted on a vehicle. In a modification the pins 13 are attached to the caliper body and are slidably received in bores in the torque plate.

Class 38(5) [Also in Groups XXVII and XXXV] In a low-tension ignition-system (see Group XXVII) the flywheel magneto incorporates an insulated contact connected to the condenser 9, Fig. 1, the other terminal of the latter being connected to the flywheel which is earthed through a slip ring 10 and brush 12. The magneto coil 5 is connected between earth and contact 6 whilst contact 8 is connected to the sparking plug 13. When the contact 6 is touched by, or in spark-gap relationship with, contact 7 the condenser 9 is charged from the magneto, the contacts being arranged to break the charging circuit when the generated voltage is at its peak; the condenser discharges through the plug 13 when contacts 7 and 8 cooperate. The contact 8 may be adjustable to vary the time of ignition. In a modification, a third fixed contact 14, Fig. 2, is connected to one terminal of the condenser 9, a member 15 on the flywheel 1 serving to bridge coaxial contacts 6 and 14 to charge the condenser and then bridge contacts 8 and 14, to discharge it through the plug. In another modification, the condensers 9, 9a, Fig. 4, are charged simultaneously, the condenser 9a being connected to two fixed and diametrically opposed charging contacts 14a and 14b and the condenser 9 to fixed contact 14; the discharging contacts 8, 8a are diametrically opposed so as to obtain a delay equivalent to half a flywheel revolution between energization of the two plugs. In a further modification, the condenser and contacts are arranged so that one is charged by positive and the other by negative magneto impulses, the discharges occurring in spaced relationship as in Fig. 4. In a final modification, the set of opposed fixed contacts is dispensed with.
