Title: Improvements in or relating to Apparatus for Forging Crankshafts and like Forgings.
IPC: B21K1/08
Filed: 1967-06-28
Abstract: 1,190,664. Forging crankshafts. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (St. Chamond-Firminy-St. Etienne- Jacob-Holtzer). 28 June, 1967 [29 July, 1966], No. 29791/67. Heading B3H. In a crankshaft forging apparatus having a pair of slidable cradles 14, 14a movable towards each other for upsetting therebetween a workpiece 21, and a transversely movable anvil 16 for forging the crankpin, the movements of the cradles and anvil are effected by an hydraulic actuator unit B through hydraulic transmission means. Workpiece 21 may be preformed with enlarged portions or these may be produced by the upsetting. Cradles 14, 14a slide on stationary rods 19, 19a having stationary pistons 20, 20a working in moving cylinders 13, 13a. These are supplied with hydraulic fluid from actuator cylinders 11, 11a which may be interconnected to ensure uniform movements of the cradles. The inner forging surfaces of the cradles may have die portions for shaping the crank webs. The crank pin is formed by a forked anvil 16 consisting of two halves (16), (16a), Fig. 7 (not shown), pivoted at 29 to a vertical slide (30) actuated by a pair of pistons 15 supplied with hydraulic fluid from actuator cylinder 12. The two fork halves (16), (16a) are pivoted by hydraulic cylinders (28) and locked in their closed position by a clamp (31) actuated by an hydraulic cylinder (33). The cradles 14, 14a have pivoted caps (25), Fig. 5 (not shown), actuated by hydraulic cylinders (26). The actuator unit B may be operated by the ram 17 of a press and the hydraulic system provides a force multiplication of at least 2: 1. The actuator cylinders 11, 11a, 12 are dimensioned so that the cradles 14, 14a are moved before the anvil 16. Alternatively the actuator units may be operated by an hydraulic pressure generator. An auxiliary pressure generator is used to supply the ancillary cylinders (26), (28), (33) and for retracting the cradles. For determining the angular position of the crank throws, a rotary jig (22), Fig. 6 (not shown), is housed in cradle 14 and rotated by a chain (23) driven by a reduction motor unit (24), or alternatively by a rack transmission driven by a cylinder unit. In another embodiment, Figs. 8-10 (not shown), the cradles are moved by pistons working in single stationary cylinders (35) and are retracted by cylinders (36).

Title: Improvements in and relating to synchronisation in television
Inventor: HOLT LEONARD
IPC: H04N5/213
Filed: 1955-10-19
Abstract: 806,646. Television. BRITISH BROADCASTING CORPORATION. Oct. 18, 1956 [Oct. 19, 1955], No. 29895/55. Class 40 (3). Relates to an arrangement for reducing the effect of noise on synchronization in a television receiver and particularly that which occurs during the suppression interval preceding the synchronizing pulse. The received signal 11, Fig. 1 (a), having noise occurring during both the synchronizing pulse 13 and suppression interval 12 is applied at terminal 14, Fig. 3, to the grid of cathode follower V1 and thence via resistor 16 to a valve V2 from which an output is derived at 17. The signal at the grid of V1 is clamped by stage 15 during the suppression intervals and is also applied via a synchronizing pulse separator 18 to trigger a " flywheel " pulse generator 19 which generates pulses, Fig. 1 (b), having leading edges 20 occurring a short time (1.75 microseconds in the example given) before the synchronizing pulses and trailing edges 21 coinciding with the trailing edges of the synchronizing pulses. These " flywheel " pulses are applied via valve V3 and transformer 22, Fig. 3, to actuate a normally open clamp circuit 23, and are also applied via a delay line 24 having a delay of 1.75 microseconds to a cathode follower V4 whereby the potential at the cathode varies as shown in Fig. 1 (c) Clamp circuit 23 operates on the signal at the grid of V2 and when actuated clamps the grid to the potential of V4 cathode, attenuating any noise that may be present in proportion to the value of the potential division provided by the resistance of the clamp and resistor 16. In operation, therefore, when the leading edge 20 of a " flywheel " pulse occurs, the clamp conducts and holds the signal, Fig. I (d), steady at potential level 25, Fig. 1 (c), which is arranged to be equal to black level. Subsequently, when the pulse reaches V4 via delay line 24 the signal is pulled down to and held steady at level 27 which is arranged to equal the original amplitude of the synchronizing pulses. At the simultaneous termination of the synchronizing and " flywheel " pulses the clamp opens, the noise during the post - synchronizing suppression period remaining unaffected.

Title: A process for the chlorination of paraffin and/or aromatic hydrocarbons
IPC: C07C17/10
Filed: 1932-10-29
Abstract: In the chlorination of paraffin and aromatic hydrocarbons, substantial chlorination by substitution in the dark with free chlorine is induced by simultaneously carrying out an addition process in the same reaction zone between free chlorine and unsaturated hydrocarbons in the absence of substantial amounts of elementary oxygen.  The process is applicable to substantially pure individual paraffins or aromatic hydrocarbons (e.g. benzene or toluene) and mixtures thereof with each other or with diluents. Unsaturated hydrocarbons specified are olefines, acetylenes, diolefines and terpenes.  The reaction is not limited by the physical state of the reactants.  The chlorine may be employed in the uncombined state as a gas.  The reaction is preferably carried out in the "mixed" phase with liquid hydrocarbon in equilibrium with its saturated vapour, e.g. by introducing chlorine into a reaction zone between two fractionating zones of a fractionating column where it comes into contact with ascending hydrocarbon vapour and descending hydrocarbon reflux.  The gaseous hydrogen chloride formed passes upwards with the excess of hydrocarbon vapour (the latter being returned as reflux), whilst the chlorination products are carried downwards in the reflux and withdrawn from the base of the column or the kettle below it either pure or mixed with a small amount of unreacted hydrocarbon. Fresh hydrocarbon is introduced at any convenient point in the column, preferably at the top.  The process is effected at temperatures from below 0 DEG  C. (e.g. in the case of propane at its boiling point of -- 41 DEG  C.) up to 100 DEG  C., or, in the case of hydrocarbons boiling above 100 DEG  C., up to their boiling points. Metallic or other opaque structural material may be employed, whilst chlorine carriers, ultra-violet light and sunlight are dispensed with.  The rate and direction of chlorination may be controlled by means of the amount and nature of the unsaturated hydrocarbon added, and more than one atom of chlorine may be introduced into the hydrocarbon molecule by the substitution reaction.  An example describes the chlorination of a mixture of butane and butylene to produce mono- and dichlorbutane. Specifications 289,795, [Class 2 (iii), Dyes &c.], and 350,395 are referred to.  The Specification as open to inspection under Sect. 91 comprises the treatment of saturated hydrocarbons with halogens in general. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to speed responsive governor
IPC: G05D13/00
Filed: 1954-10-27
Abstract: 760,656. Fluid-pressure servomotor-control systems. GARRETT CORPORATION. Oct. 27, 1954 [Nov. 9, 1953], No. 30997/54. Class 135. A speed-responsive governor comprises a fixed housing containing a rotor driven by mechanism to be governed, a pressure fluid inlet to the interior of the housing, a centrifugally operated valve in the rotor controlling an output pressure which is applied to means for controlling the speed of the governed mechanism, and a pressure-responsive element interconnecting and sealing the centrifugallyresponsive element with the rotor and subject to the pressure difference across the valve. In an embodiment the rotor 24 is mounted in bearings 20, 21 and carries a spring-biased plunger 29 which has at its upper end a closure surface 49 co-acting with a fixed element 50. Pneumatic pressure, after passing through a restriction 18, enters the casing 10 and passes through openings 51 in the fixed member 50 to a space where it acts on a diaphragm 46 in a direction opposing the spring 31 and assisting the centrifugal force on the member 29. When a predetermined speed is reached the valve opens to allow escape of air through passages 52, 41, 42, 43, thereby lowering the pressure in the casing 10 and consequently in a passage 19 which leads to pneumatic mechanism for controlling the speed of the governed apparatus. To compensate for the variation in centrifugal force on the member 29 due to its displacement relative to the axis of the rotor the air on the outlet side of the valve has access to the lower surface of the diaphragm. In a modification, the valve member is arranged to be normally open and to close in response to increase of speed.
