Title: Improvements in and relating to lathe tool holders
IPC: B23Q16/08
Filed: 1938-02-09
Abstract: 488,539. Lathe tool-holders ; turrets. SIMMEL, M. Feb. 9, 1938, No. 4090. [Class 83 (iii)] In a turret-type lathe tool-holder, the tools m are fixed in slots l in a conical head k by screws n whose heads lie in recesses o and thus do not cause an obstruction when the head k is rotated. The head is attached to a stem g passing through a shank a and is located by pins r on the head engaging recesses f in the shank. The lower endof the stem g has a left-hand screw-thread h co-operating with a hand-operated nut u by which the head is secured in operative position, a spring s normally pressing the head downwards. In order to change the tool position, the nut u is screwed downwards against a stop w, secured to the stem by a right-hand thread i, and the head is pushed upwards to withdraw the pins r from the recesses f and allow rotation of the head. A flanged collar q attached to the head prevents ingress of cuttings &c. between the head and shank in the raised position. Two sides of the shank are flattened to enable it to be clamped to the cross-slide y of a lathe by a plate x, and the upper end b is conical to form a continuation of the head k.

Title: Improvements in or relating to cooling members of absorption refrigerating apparatus
IPC: F25B39/02
Filed: 1949-02-17
Abstract: 665,683. Refrigerators. ELECTROLUX, Ltd. Feb. 17, 1949 [March 2, 1948], No. 4340/49. Class 29 A cooling member of plate-like form for absorption apparatus of the continuouscycle inert gas type includes two plane pipe coils 18, 19 operating at different temperatures and interconnected to provide series flow of refrigerant, a plane tangential to one coil being located between planes tangential to the other coil. A deep-freeze compartment 14 is separated from the food space by an insulating partition 11 and from an icemaking compartment 13 by the cooling member having upper and lower plates 15, 20 with the evaporator coils 18, 19 between them and secured by clips 17 to the lower and upper plates respectively. The two plates are insulated from each other by a filling 21. The coils comprise a number of U-bends as shown in plan in Fig. 2 and refrigerant is supplied by a pipe 23 to the coil 18 so that the lower plate 20, forming the ceiling of the deep freeze compartment, is strongly cooled. The refrigerant then passes into the coil 19 cooling the upper plate 15, unevaporated refrigerant passing to a finned coil 26 cooling the food space. When water-filled ice trays are placed on the plate 15 for freezing, the consequent rise of temperature does not affect the coil 18 and plate 20, avoiding deterioration of deep frozen foods in the compartment 14. Inert gas flows in the same direction as the refrigerant. A cold accumulator comprising a flat receptacle containing a eutectic may be arranged on either or both sides of the cooling plate. In a modification the icemaking compartment is arranged below the deep-freeze compartment and is cooled by coils in its ceiling, the ice-making compartment being cooled by the upper plate of the cooling member, and the food storage compartment by the lower plate, which has fins projecting into the compartment. The roof of the refrigerator may be of thicker insulation than the walls. The incoming refrigerant is cooled by connections 24 to the gas heat exchanger 22, Specification 665,731. is referred to. The Specification as open to inspection under Sect. 91 descibes also a single coil clamped between an upper plate and a lower cold accumulator. This subjectmatter does not appear in the Specification as accepted.

Patent GB-415383-A (GB)
Title: Improvements in the manufacture of carbohydrate compounds
IPC: C08B11/08
Filed: 1933-02-16
Abstract: In the manufacture of oxyalkyl ethers of carbohydrates suitable for use as sizes, dressings and finishes for textile and other purposes, the carbohydrates are reacted with alkylene oxides under pressures of at least five atmospheres.  The invention is concerned more particularly with the production of cellulose ethers containing 1--2 oxyalkyl groups per C6H10O5.  The temperature may be such that the alkylene oxide is wholly liquid or it may be partially or wholly gaseous and the pressure may be due entirely to the vapour of alkylene oxide or may be partly due to the presence of other gases or vapours, e.g. nitrogen or carbon-dioxide.  The reaction may be carried out in the presence of acids or acid salts, alkalies, or bases.  Cellulose may be pretreated with acids or bases, strong acids when used for such a treatment being preferably removed before the oxyalkylation.  The reagents used for the oxyalkylation include ethylene oxide and its homologues, glycide, epichlorhydrin or mixtures of alkylene oxides.  When using the epichlorhydrin type of reagent, if the halogen atom constitutes the etherifying group alkali must be present, while if the alkylene oxide group is to react, the reaction should be under neutral or acid conditions.  The oxyalkyl derivatives may be esterified, to produce substances suitable for the production of lacquers, plastics, filaments or films by the usual methods, the said products being then subjected, if desired, to any suitable after treatment processes.  In an example, cotton linters containing about 10 per cent by weight of caustic soda are heated with 2--4 times their weight of ethylene oxide at a temperature of 80--100 DEG  C. and a pressure of 6--8 atmospheres for 4--6 hours, or until the desired content of ether groups is obtained.  In a modification, cotton linters pretreated with acetic acid are treated with 2--4 times their weight of ethylene oxide in the presence of nitrogen or other inert gas at a temperature of 40--60 DEG  C. and a pressure of 12--15 atmospheres, and in a third example, cotton linters either pretreated with acetic acid or containing about 10 per cent of caustic soda are heated with 3--5 times their weight of propylene oxide in the presence of nitrogen at a temperature of 50--70 DEG  C. and a pressure of 25--30 atmospheres.

[Class 38 (v)] [Also in Group XXIV] The shafts operating each group or bank of resistances, reactances, or shutters forming dimmers for lamps are each coupled with a master shaft through electromagnetic friction clutches whereby, on selective excitation of the clutches, a given motion of the master shaft produces movement of any dimmer shaft in one direction or the other. In the arrangement shown, the master shaft 1 may be rotated in either direction by gearing 2, 3 so as to move the links 11, 12 oppositely up or down. The links are coupled to dimmer shafts 4, 5; 6 through electromagnetic friction clutches 7, 8 which are independently operated as required to secure actuation of any of the dimmer shafts in either direction. The movement of the clutches is in this construction limited to 180‹, but in alternative constructions, the master and other shafts may rotate continuously, chain and toothed gearing being employed in one construction and bevel gearing in another. Reference has been directed by the Comptroller to Specifications 373,625 and 377,363.
