Title: Improvements in derricks of the self-slewing type
IPC: B66C23/60
Filed: 1928-12-11
Abstract: 326,458. Gray, A. G. Dec. 11, 1928. Blocks acting on drums; actuated by springs and weights; actuated b y speed regulators; fluidpressure brakes.-Relates to self-slueing derricks controlled by brake-blocks acting on drums on which the guy-ropes are wound, and is a modification of the arrangement described in Specification 231,581. Two guy ropes at opposite sides of the derrick are wound on two drums 3 loose on a shaft 2, and a tail-rope from the two drums forms a bight in which hangs a bob-weight, to take up slack in the guy ropes. A spring may be used instead of the weight. The brake-block 4 which acts upon the two drums 3 to hold the derrick by means of the guys, is now arranged vertically over the drums so that its weight is added to the braking pressure of the spring 9. The brake-block is of piston form, and screws 5b in the casing engage grooves 5, 5<a> in the block to prevent twisting. The brake-block is lifted from the drums 3 by turning a lever 7 and spindle 6 which works in a quick-threaded nut 8 in the block. The drums are mounted on a T-head on the mast and the brake-release lever 7 may be operated by a hand-lever or by steam or electric gear. The steam release gear comprises a single-acting single-stroke cylinder 21, Fig. 7, the piston 24 being raised by a spring 27, and forced down by steam admitted through the hand-operated valve 23 so as to pull on a rope connected to the lever 7. The electric release gear comprises a motor 41 with an extended spindle 42 fitted with weighted arms 51, 52 which act by centrifugal force against the resistance of a spring and draw down a sleeve 43 which is connected by a rope with the lever 7.

Title: Improvements in sliver roll-forming machines
IPC: D01G27/04
Filed: 1932-12-28
Abstract: 408,405. Sliver roll-forming machines. FRASER, G., FRASER, N., and FRASER, J., Westburn Foundry, Arbroath, Angus, Forfarshire. Dec. 28, 1932, Nos. 36649/32 and 9286/33. [Class 120 (i).] A sliver roll-forming machine comprises a pair of spaced relatively fixed cheek plates 1, Fig. 1, mounted for joint pivotal movement on a horizontal shaft 2, a frictional pressure or driving roller 5, a coaxial pair of arbor sections 4, 4<a> carried one by each cheek plate and retractable to permit ejection of the completed roll, a segment member 21 concentric with the shaft 2, and at least one friction member engageable with the segment 21, either the segment 21 or the friction member being fixed and the other movable with the cheek plates 1. Each arbor section 4, 4<a> is carried by a sleeve 9, Fig. 2, formed with a cam groove 11 engaged by a fixed pin 12 so that rotation of the sleeve 9 causes axial displacement of the arbor section. The arbor sections are connected by operating arms 14, 14<a> links 15, 15<a> and arms 16, 16<a> to a rock shaft 17 for simultaneous operation by a handle 18. The sliver 49 is traversed by a guide 31 carried by a horizontal tube 32 and reciprocated by differential drive mechanism comprising a friction wheel 35, Fig. 3, moved radially of its driving disc 34 as the roll grows by means of a bell-crank lever 39, 41 controlled by a cam 37 moving with the cheek plates 1. A disc 42 on one end of the shaft 36 carrying the wheel 35 is provided with a crank pin 43 which through a link 45 reciprocates a spindle 44, a bar 46 secured to the tube 32 being pivotally connected to the spindle 44 and serving to reciprocate the guide 31. The tube 32 engages a fender-cam 33 to prevent contact with the roll. The segment 21 is engaged by opposed arcuate friction pads 19, 20 secured to shoes 19<a>, 20<a> slidably guided in the cheek plate 1 and embraced by a yoke 23 provided with pins 24, 25 engaging the shoes. The pin 24 is screwed through the pivoted end of a lever 26 pivoted at 27 to the yoke 23 and through which pressure may be applied to the pads 19, 20. A bar 30 is provided to support the completed roll 29 during removal, while the cheek plates 1 may be raised or lowered by handles 47. The main shaft 6 is driven through change speed gearing from the drawing-frame delivering the sliver 49.

Patent GB-368389-A (GB)
Title: Improvements in or relating to electric upsetting apparatus
IPC: B21J9/08
Filed: 1930-12-06
Abstract: 368,389. Forging - machines. BENEDETTO, G., 45, Via Dante Alighieri, Novara, Italy, and OMES HOLDING CO., Ltd., 55, Pall Mall, London. Dec. 6, 1930, No. 36857. [Class 83 (iv).] Electric upsetting apparatus comprises a direct current driven rotary converter for producing alternating current, connections from the rotary converter to a step-down transformer and electric heating means supplied by the transformer. The rotary converter preferably has a steeply-falling load-speed characteristic so that when load is applied part of the energy required is supplied from the kinetic energy of the moving parts of the converter, which may have a heavy flywheel to increase the effect. The A.C. output terminals 31 of the rotary converter 32 supply the primary 28 of the step-down transformer, the secondary 27 of which has its terminals connected respectively to the anvil electrode 13 and vice electrode 15. The upsetting of the work-piece 26 is effected by the head 21 of a screw plunger 20 ; a spring 22 is interposed between head and plunger which are provided with contacts 56, 57 in a control circuit including a solenoid 51 adapted to close contacts 52, 53 in the transformer primary 28. The plunger 20 is advanced or retarded by a wheel nut 25 and pinion 38 on a shaft 43 adapted to be driven in opposite directions from the motor 34 by gear trains 35 .. 37, 39 .. 42, and electrically controlled friction clutches 44, 45. The operation is started by a normally-closed switch 46 which is opened automatically when the operation is complete. Switch 46 closes the circuit 48 of a solenoid 16 actuating the clamping jaw 17 of the vice electrode 15 and a solenoid 55 actuating friction clutch 44 so that plunger 20 is advanced. If overheating occurs the increased softening of the work-piece allows the head 21 to be forced away from plunger 20 by spring 22, contacts 56, 57 become separated, thus opening the control circuit of solenoid 51 and opening the contacts 52, 53 of the transformer primary 28. At the end of the operation a contact 61 on the head 21 engages a contact 60 and closes another control circuit including solenoid 58 which breaks the transformer primary circuit and another solenoid 47 which opens switch 46. This opens circuit 48, thus releasing the vice electrode gripping jaw 17 and friction clutch 44, thereby stopping advance of the plunger 20. At the same time switch 46 engages another contact 62 closing a circuit 63 including a solenoid 65 actuating clutch 45 so that plunger 20 is retracted ; when the plunger reaches the limit of its rearward movement it separates a contact 67 from contact 66 and opens circuit 63, 64, causing clutch 45 to be released. Specification 352,508 is referred to.

Title: Improvements in or relating to the trunk line systems in telecommunication systems
IPC: H04L12/00
Filed: 1964-09-09
Abstract: 1,046,188. Automatic exchange systems; telegraphy. SIEMENS & HALSKE A.G. Sept. 9, 1964 [Sept. 10, 1963], No. 36871/64. Headings H4K and H4P. A group of both-way junctions is provided at each end with delay means whereby on the termination of a call over one of the junctions one of said ends is released more slowly than the other. The invention is applicable to a group of intercontinental trunks provided at each end with a call queueing arrangement. When a junction becomes free, simultaneous seizure thereof from both ends by waiting calls is prevented by the longer delayed release at one end, the other end thus being given priority. The delay may be applied to only some of the junctions, to some of the junctions at one end and to other of the junctions at the other end, or to either end in dependence upon the time of day. As described, the junctions FL are 4-wire and are used for carrying telegraphic traffic. A junction is terminated at each end by a two-wire line a, b, but separate incoming and outgoing selectors VS are connected to this line. Upon seizure of a junction a monitoring relay M connected across the contacts of a polarized telegraphic relay AE at one end of the junction brings up a delayed-release control relay G, whose release time is governed by a shunting capacitor C1. This relay opens the energizing circuit of a busying relay CA in the P-wire so that upon relapse of CA on the termination of a call it cannot be re-operated until the control relay falls back.

Title: Process for the preparation of alkali metal salts of fructose diphosphate from insoluble salts thereof
Inventor: BARUCHELLO GIANFRANCO
IPC: C12Q1/527
Filed: 1960-11-03
Abstract: An alkali metal salt of fructose diphosphate is obtained by bringing a water-insoluble alkaline earth metal salt of fructose diphosphate, in aqueous medium, into intimate contact with a cation exchange resin whereby the free fructose diphosphate is liberated by ion exchange, and then bringing the latter into contact with alkali metal ions in an anhydrous organic medium.  In a preferred embodiment the insoluble alkaline earth metal salt is suspended in water and brought into solution by adding a readily volatile organic acid, e.g. acetic acid, the resultant solution is passed through a cation exchange resin column to obtain the free fructose diphosphate, the effluent solution is then concentrated under reduced pressure until all the water and volatile acid are removed and the residue dissolved in an anhydrous organic solvent, e.g. a C1-C3 alkanol and a solution of the alkali metal in the same organic solvent added, with stirring, to form the desired alkali metal salt which is then filtered off, washed with the anydrous organic solvent and dried under sterile conditions. Specified alkaline earth metal salts are the calcium and barium salts and specified alkali metals are sodium and potassium. The cation exchange resin is preferably one of the acid regenerated type, e.g. a sulphonated polystyrene resin.  The products are water-soluble and have therapeutic properties. They can also be used to determine the aldolase content of the blood.
