Title: Improvements in and relating to hydraulic presses
IPC: B30B15/16
Filed: 1941-07-10
Abstract: 544,331. Hydraulic presses. SHAW & SONS (SALFORD), Ltd., J., and SHAW, J. B. July 10, 1941, No. 8686. [Class 69 (ii)] In a hydraulic press of the kind in which a reversible pump A supplies operating liquid to the pressure cylinder B and also to the pushback cylinders C, shock is prevented on reversal of the pump by preventing the supply of pressure fluid to the cylinders C until pressure has dropped in the cylinder B to a predetermined amount. A bye-pass valve 8 is maintained open against the action of a spring by pressure admitted by a pipe 6 connected to the supply pipe 1 of the cylinder B, and it is only when the valve 8 closes that pressure liquid can pass from the pipe 2 to the cyclinders C, and the closure of the valve takes place when the pressure in the pipe 6 reaches a predetermined value. Specification 525,913, [Group XXII], is referred to.

Abstract: 417,055. Waffle irons. RICHERT, J., (trading as SIMON & CO., W.), 44, Forsthofstrasse, Nuremberg, Germany. March 23, 1933, No. 8787. [Class 28 (i).] In apparatus for cooking wafers, waffles, and the like, of the kind in which opposed electrically heated plates are used, temperature control means are provided in each plate. The heaters may be arranged in series or in parallel. Fig. 4 shows a series arrangement and Fig. 3 shows the arrangement of the heat-sensitive device in each plate. A bi-metallic strip 10 is anchored to a fixed post 11 and has contact studs 12, 13 which make contact either with a contact 14 or a contact 16, the latter being carried on a springy strip 17 in electrical connection with a terminal 18. A lever 21 enables the device to be used as a simple thermal switch or as a change-over switch. The strip 10 is adjusted and controlled by a nut 20. The current passes from the post 11 to the terminal 15 or to the terminal 18. The heating-means in the upper plate comprises elements 4, 4<a> and in the bottom plate comprises elements 5, 5a. According to the operation of the thermostats, one or both of the elements in each iron may be functioning or both elements may be cut out in one iron whilst both are functioning in the other. The current is supplied to the heaters from terminals 7, 8, Fig. 2. At the front of the top plate 2 is pivotally connected a locking-lever 22 having a hook-shaped part 22b which engages under a roller 23 to lock the plates together. The roller is carried on a plate 24 pivoted at one end at 24<a> and having a screw 25 at the other end for adjusting the plate. The plate is formed with a slot 24b in which a bush 26 is slidable, and a screw 27, passing through the bush, is tightened to lock the plate 24 in its adjusted position.

Title: Hydrogenated spiramycins
IPC: C07G11/00
Filed: 1956-03-23
Abstract: <PICT:0785191/IV (a)/1> A new antibiotic is an hydrogenated spiramycin containing at most 4 hydrogen atoms, additional to those present in the spiramycin, or a salt of such hydrogenated product. The spiramycin is the mixture of the spiramycins I, II and III which is obtained by the fermentation of S. ambofaciens, according to Specification 758,726, the individual spiramycins I, II and III or any admixture thereof.  The spiramycin or a salt thereof, is subjected to catalytic hydrogenation preferably in solution and under normal pressures and room temperature.  The catalyst may be Raney nickel, but a noble metal, e.g. palladium or platinum is preferred, particularly palladium which may be supported on alumina, carbon or barium sulphate.  Using a palladium catalyst absorption stops automatically after four hydrogen atoms have been absorbed and is particularly suitable for the preparation of dihydrospiramycin I. Specified solvents are alcohols such as methanol, ethanol and isopropanol, ethers such as diethyl ether and dioxane and esters such as ethyl acetate.  Examples relate to the preparation of (a) tetrahydrospiramycin, (b) tetrahydrospiramycin sulphate, (c) dihydrospiramycin I, (d) tetrahydrospiramycin I, (e) tetrahydrospiramycin II, (f) tetrahydrospiramycin III, (g) mixture of tetrahydrospiramycins II and III.  Tetrahydrospiramycin has a melting point of 120-125 DEG  C., optical rotation of [d]17D = - 71.5 DEG (C=1 per cent methanol), ultraviolet absorption maximum 820 mm , E1cm.1%=14 (ethanol) and infrared absorption spectrum at the following frequencies expressed in reciprocal centimetres 3470, 2930, 2800, 1730, 1620, 1462, 1453, 1410, 1372, 1318, 1289, 1270, 1232, 1182, 1160, 1120, 1075, 1050, 1015, 991, 971, 956, 903, 841, 808 and 783.

IPC: A61K38/00

Abstract: 1,117,948. Extracting medicinal protein. TEIKOKU HORMONE MFG. CO. Ltd. 3 March, 1966 [3 March, 1965], No. 9396/66. Heading A5B. An active material having biological activity with respect to the nervous system is obtained from the submaxillary glands of ungulate mammals, e.g. cattle, horses and swine, by extraction with an aqueous medium e.g. water or 2% saline, precipitating the protein therefrom, redissolving the precipitate and separating the active fraction from the large amount of inactive mucoid present therein. This may be achieved by fractional precipitation of the mucoid by addition of a salt, acid or watermiscible organic solvent or by adding a watersoluble zinc salt which forms a complex with the active material, which may be precipitated free from mucoid by addition of acetone or ethanol. The active material is separable into two fractions e.g. by treating an aqueous saline solution thereof with a weakly basic solution of acrinol, a protein/acrinol complex effective with respect to the proliferation of glial cells is precipitated and a protein effective with respect to the growth of neurons and the regeneration of axons remains in solution. Both may be purified by ion-exchange techniques.
Patent GB-727484-A (GB)
Title: Method and apparatus for welding
IPC: B23K9/167
Filed: 1952-04-15
Abstract: 727,484. Welding by fusion. AIR REDUCTION CO., Inc. April 15, 1952 [April 26, 1951], No. 9405/62. Class 83 (4). A method of propelling a welding electrode 4, Fig. 1, to form a weld bead comprises establishing an arc between the electrode and a workpiece, positioning a filler wire 14 so that when the arc is moved over the surface of the work-piece in the direction of the filler wire an end of the wire is frictionally restrained by the work-piece at the edge of the weld puddle and then melted to form a constituent of the puddle, and applying a force to the wire to create a reaction force which is applied to the electrode to propel it over the surface of the work-piece in the direction of the wire. Two circumferentially-grooved rolls 25, Fig. 6, one of which is mounted on a pivoted spring-loaded arm 29 are driven through reduction gearing 19, Fig. 4, by a governor-controlled motor 17 to feed the wire from a rotatable drum 43 through a flexible conduit 13 to the weld puddle. The drum 43, which is enclosed by a transparent plastic cover 62 and a fabric cover 66 secured by a slide fastener 67, is removably mounted on a fixed spindle 49 and braked by an adjustably spring- loaded collar 55 to prevent back-lash. A wirestraightening device preceding the rolls 25, 26 comprises three rolls 72, 73, 74, the position of the roll 74 being adjusted by a screw 79 until it abuts an adjustable stop-screw 80. An arc may be struck by bringing the electrode into momentary contact with the work or by a highfrequency oscillator 92, Fig. 5, which is energized by a pedal switch 93 connected across an A.C. supply 88, 89. This switch simultaneously open-circuits a time delay relay 94 which closes contacts 94a to energize solenoids 96, 97 controlling cooling water and gas valves. After the arc has been established welding current is supplied by a generator 85 which, through relays 90 and 91, closes contacts 91a to start the wire feed motor 17 and opens contacts 91b to prevent re-energization of the relay 94 when the switch 93 is released. A resistance 99 and a condenser 100 ensure quick response of the relay 90 and a high-frequency by-pass condenser 101 protects the relays and generator when the oscillator is energized. The means for supporting and feeding the filler wire are insulated from earth and a condenser 84, Fig. 6, by providing a low-resistance path for high-frequency current, eliminates any tendency to arcing across the insulation. Cooling water passes through hoses 5 and 6, Fig. 1, while an inert shielding gas, such as argon or helium, passes through a hose 7. The conductor for welding current may pass through the hose 6. Specification 687,666 is referred to.
