In a crank-shaft forging apparatus having horizontally slidable opposed end tools A, B and a synchronized transversely acting centretool C for forging the crank throw, the inner face of each end tool has an open-ended vertical channel 13, 6 for confining lateral spread of the web whilst lower and upper parts 16, 18 of the centre tool have side pads 15, 17 for restricting metal flow at the heels and toes of the webs. The end tool B has upper and lower halves 2, 3 with inner end walls 5 providing the vertical channel 6. One or more location plates 4 positions an unforged portion 1c of the workpiece 1 or alternatively a previously forged crank throw. The other end tool A which receives the unforged portion 1d of the workpiece has separate end walls 9, 10 providing the vertical channel 13. The pads 15, 16 of the centre tool C close the lower and upper ends of the channels to define cavities for forming the crank webs.

Title: Improvements in electro-mechanical transducers
IPC: H04R11/00
Filed: 1946-10-10
Abstract: 628,587. Circuits for magnetic instruments. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 10, 1946, No. 30307. Convention date, Feb. 3, 1943. [Class 40 (iv)] Two coils 1, 2 of a transducer, e.g. a record cutter, are separated by an inductance 3, and the series circuits 1, 3 and 2, 3 are shunted respectively by condensers 4, 5, which form together with the inductance 3 series resonant circuits shunting the coils 1, 2. The resonant frequencies of these circuits are made equal to the mechanical resonance frequency of the system, thereby reducing the response at this frequency. The condensers 4, 5 are also of such a value as to produce a resonance with the mechanical system at a frequency higher than the mechanical resonance frequency where the response would normally fall off.

Title: Circuit arrangement to establish testing connections in telecommunication, particularly telephone exchange systems which have switching grids, controlled by markers
IPC: H04Q1/22
Filed: 1965-07-16
Abstract: 1,101,022. Automatic exchange system. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 16 July, 1965 [23 July, 1964], No. 30310/65. Heading H4K. In a system employing a read relay switching network that is controlled by a route simulating network, testing of particular crosspoints is effected by means of a test circuit which can mark particular outlets of the one-only-selectors associated with each node of the simulating network. A single oneonly-selector may be used by each node in turn. It should be noted that normally in marker controlled systems test calls between particular inlets and outlets may use any route depending on the whim of the marker, the present system preselects a route and sets it up by acting on the marker and not (as is also known) by acting on special test wires associated with the switches. The simulator is of the type wherein " forward " (from the junctor end of a connection to be set up) offering potentials are passed via all free guide wire paths whereafter " backward" access (or accepting) potentials are transmitted whereby at each node a one-only-selector selects one of the double-marked guide wires. As shown, the one-only-selectors PK1, PK2 when supplied with suitable potentials over the guide wires z11-z13 and z21-z23 associated with switching stages KS1 and KS2 respectively, operate one of their relays p11-p23 so as to select a unique path. In order to set up a test connection, an operator actuates key St whereby relay pr in a so-called group marker, comes up and seizes the individual markers SM1, SM2 of the switching stages. Switches VS1, VS2 are then set (in an unspecified manner) to one of their outlets whereby potentials, which effectively simulate the normal offering and access potentials, are applied over particular ones of the wires 8p11-8p23 to the markers whereby a particular pk relay in each comes up and the corresponding switching network testpath is then completed. It is suggested (without details) that a single marker for controlling all of the switching stages may alternatively be used.

The stud 10 has a body 11 and is provided with an annular groove 24. A disc 13 is clamped between the body 11 and face 14 of the member 1. The plate 3 is provided with a slot 15 and a circular recess 18. The locking member 17 is received in the recess 18 in the plate 3 to effect locking and comprises a body 19 having a central bore 20 with a cylinder 21 therein, the latter being urged by a spring 22 and having holes with balls 23 therein for engagement with the annular groove 24. A catch 25 is fitted in the body 19 where it is held by a plate 26 so that it can be moved into a locking position, to hold the cylinder 21 against the force of the spring 22, and a release position in which the cylinder can be moved down by the spring, an enlargement 27 of the bore receiving the balls 23 when in the release position. The catch 25 is actuated by a key-operated cylinder lock 28. In a modification a locking member 31, Figs. 4, 5 and 6, comprises a body 33, a plate 34 held by screw 35, a cylinder 36 which receives a stud 32, and a spring 37 which urges the cylinder 36 towards the plate 34. The cylinder 36 is stepped at 38 to provide a portion 39 which projects through the plate 34 and engages a collar 40 on the stud 32, and has a hole 41 with a ball 42 therein, the ball being engageable with an annular groove 43 formed in the stud 32. The cylinder 36 is held in its upper locked position by a ball 45 which is forced under the step 38 by a cam ring 46 having arcuate slots 47 through which the screws 35 pass, the cam ring 46 being urged by a compression spring 48. The movement from the locked position in Fig. 5 to the unlocked position in Fig. 6 is effected by a cylinder lock 49 which is mounted in the body 33 and carries a projecting pin 50 which engages surface 51 of the cam 46. The cam surface 51 can engage the ball 45 and forces it under the step 38 of the cylinder 36. The ball 45 can move outwardly into a hollow 52 in the cam to allow outward movement of the cylinder 36. The locking mechanism 31 is provided with a dead lock which comprises a pawl 53 which is pivoted at 54 in a slot 55 in the cam 46, is engaged by the pin 50 and is urged by a leaf-spring 56. A ball 57, located in a hole in the cam 46 is held by the pawl 53 in a recess 58 in the body 33 when the pawl is in its locking position as shown in Figs. 4 and 5. Operation of the cylinder lock to unlock the device rotates the cylinder 49 and causes the pin 50 to pivot the pawl 53 outwardly to clear the ball 57, the latter drops out of the recess 58 and unlocks the cam 46. Continued movement of the pin 50 moves the cam 46 to its unlocked position shown in Fig. 6.
