Patent GB-1024811-A (GB)
Title: Improvements in or relating to peroxy compounds
Inventor: MANLY THOMAS DAVID
IPC: C07C409/38
Filed: 1962-01-12
Abstract: Compounds of the general formula <FORM:1024811/C3/1> wherein R is a hydrogen atom, an acyl or alkyl group, or the group CH3-CH(OR1)-CH2-C(CH3)2-, and R1 is a hydrogen atom or an acyl or alkyl group (see Division C2), may be used in the cross-linking of substantially saturated polymers such as polyethylene, polypropylene and silicone rubbers where free radical generation at temperatures of the order of 150 DEG  C. is desirable.ALSO:The invention comprises compounds of the general formula <FORM:1024811/C2/1> wherein R is a hydrogen atom, an acyl, for example aroyl, group or an alkyl group, or the hexylene glycol residue CH3-CH(OR1)-CH2-C(CH3)2-, and R1 is a hydrogen atom, an acyl, for example aroyl, group or an alkyl group. The compounds in which R is a hydrogen atom or an alkyl group and R1 is an alkyl or acyl group may be prepared by reacting the secondary alcoholic group of hexylene glycol (2-methyl-penton-2,4-diol) with an acyl halide or an alkylating agent under conditions such that substantially no reaction occurs with the tertiary alcoholic group, and then reacting the product thus obtained, in the presence of strong acid, either with hydrogen peroxide to give a product in which R=H or with an alkyl hydroperoxide to give a product in which R=alkyl.  The compound in which R=R1=H may be obtained by careful hydrolysis of the product of the above process in which R=H. If the above procedure employing hydrogen peroxide is conducted with a molar ratio of hexylene glycol: hydrogen peroxide of 2: 1, careful hydrolysis of the product yields the compound of the above formula in which R1=H and R=hexylene glycol residue.  Compounds in which R is acyl or alkyl and R1 is acyl or alkyl can be obtained from the product of the hydrogen peroxide process above in which R=H and R1=acyl or alkyl by reaction with an acylating or alkylating agent. In a modification, the step involving hydrogen peroxide or an alkyl hydroperoxide may be conducted as an aceotropic distillation under mildly acid conditions.  Using the latter process the first step of protecting the secondary alcoholic group by acylation or alkylation may be omitted unless, in the product, R and R1 are not H and are to be different in which case the group R1 must be introduced prior to the introduction of the peroxide group.  Products in which R and R1 are not H and are the same may be obtained by preparing the compound in which R and R1=H and then acylating or alkylating both the hydroperoxide and the secondary alcoholic group simultaneously. Examples are given.

IPC: B23Q35/10
Filed: 1924-01-17
Abstract: 231,609. British-American Tobacco Co., Ltd., and Marsh, H. J. Jan. 17, 1924. Milling - machines; attachments for milling.-A device for milling grooves of varying width and depth and described particularly tvith reference to milling the grooves of bell-mouthed formers for cigarettemaking machines, comprises a work-carrying table D which is pivoted at d on a slide C, the latter being guided to make angular movements about a vertical axis, as it is traversed past a stationary cutter H. A screw G driven through bevel-gearing traverses the slide and transmits motion through spur gearing to one of the members of a clutch I through which the screw f may be driven to move the wedge F relatively to the slide C, thereby varying the inclination of the pivoted work-table and correspondingly varying the depth of the groove being cut. The clutch may be automatically controlled either mechanically by linkage and tappet, or electrically by a contact-maker on the slide, which completes a solenoid circuit actuating the clutch lever. The slide C carries a roller c<2> engaging a guide k on a table K whereby angular movement about a vertical axis is transmitted to the work E, Fig. 3. The guideway is formed as a switch-cam, the roller c' first travelling along one arm k<3> and the arm k<5> while the cutter produces one side of the groove e<2>, after which the plate k<2> is switched transversely to cause the roller to traverse the arm k<4> on the return movement of the slide, during which movement the cutter generates the other side of the groove. The switch-plate is guided by slots engaging pins k<9> and spring plungers k are provided to snap into fixed recesses k<7> to retain the switch-plate in the set position. The apparatus may be fitted as an attachment to, or may be built as, a machine.

Title: Improvements in or relating to thermopiles
IPC: H01L35/34
Filed: 1959-01-15
Abstract: 902,457. Thermopiles. SIEMENS-SCHUCKERTWERKE A.G. Jan. 15, 1959 [Jan. 17, 1958], No. 1526/59. Class 37. [Also in Group II] A method of constructing a thermopile comprises forming thermopile elements on a support of poor thermally conductive insulating material by a process including vapour deposition and subsequently vapour depositing a material of high thermal conductivity over each boundary between two of said elements. In a preferred embodiment a continuous strip of bismuth tellurium alloy is formed on a support of glass or ceramic by vacuum deposition from the mixed vapours of bismuth and tellurium through a mask. Selenium is then vapour deposited through a mask on to a series of evenly spaced regions B of the strip and antimony deposited from the vapour phase on the intervening regions A. The selenium and antimony are incorporated in the bismuthtellurium alloy on solidification to form alternate regions consisting of solid solutions of bismuth telluride/bismuth selenide and bismuth telluride/antimony telluride respectively. Silver iodide is next vapour deposited on the former regions B and incorporated therein as a donor impurity, and tin vapour deposited on the regions A to provide acceptor doping. Copper or aluminium is subsequently vapour deposited through a mask to form layers overlying the junctions of regions A and B and lugs C integral therewith disposed alternately on opposite sides of the thermopile. In an alternative embodiment in which the regions A and B are respectively of P and N type bismuth telluride, the selenium and antimony depositing steps are omitted from the above process.

Title: Improvements relating to the manufacture of hollow articles
Inventor: ZIMPEL ADOLF
IPC: B21C23/14
Filed: 1953-01-20
Abstract: 737,411. Making cupped articles. STAHLUND ROHRENWERK REISHOLZ GES., [formerly STAHLUND ROHRENWERK REISHOLZ AKT.-GES]. Jan. 20, 1953, No. 1662/53. Classes 83 (2) and 83 (4). A method of making tubular articles closed at one end includes piercing by a mandrel a billet positioned in a die, extruding said pierced billet through the nozzle of the die by the combined action of the mandrel and a ram coaxial therewith and engaging the end face of the billet, said mandrel moving through the nozzle and carrying the extruded material through annular draw-plates or rolls. Billet piercing.-A billet 21, Fig. 3, held by a ram 5 in a die 12 against an extrusion nozzle 13 thereof, whose outlet is blocked by a pressureplate 16, is pierced by a mandrel 6 extending through a central bore of the ram and given this piercing movement by a pair of hydraulic plungers 9. Extruding; cupping; rolling.-The pressure plate 16 is then removed and the mandrel 6 is forced forward by a rack 8, and the ram 5 by a pair of hydraulically-operated plungers 3, together to extrude the pierced billet through the nozzle 13, the mandrel 6 moving through the nozzle to carry the extruded material through similar draw-plates 14 or rolls. The ram exerts a force on the rear end of the workpiece sufficient to cause the work-piece to enter the plastic state and an additional force to overcome friction between the work-piece and the die. The ratio of the force exerted by the mandrel to the additional ram force is greater than or equal to the ratio of the diameter of the mandrel to the diameter of the die (i.e. the ram). A shaped disc 17, Fig. 5, on the face of the ram 5 ensures that the extruded article has only a thin collar in the die 12, which collar may be readily extracted from the die by further movement of the mandrel. Friction between the work-piece and the die 12 may be reduced by lubrication.

Filed: 1972-01-14
Abstract: 1434721 Testing spark gaps R W D MACDONALD 16 April 1973 [14 Jan 1972] 1805/72 Heading G1U Spark voltage is measured by connecting a measuring capacitor to the generating system such that the spark power generates a voltage on the capacitor, the peak value of which is measured. In Fig. 1 (not shown) a standard gap is connected to a high voltage line and to earth via a measuring capacitor. When the spark occurs, the breakdown voltage is applied to the capacitor. In Fig. 2 (not shown), a pair of capacitors is connected in parallel with the spark gap, the "earthy" capacitor having a diode across it. At the breakdown of the gap, the "earthy" capacitor receives a charge proportional to the breakdown voltage. For testing I.C. engine ignition systems, the circuit of Fig. 1, in unit 5 calibrates the system with the switches SW1, SW2 in position 1, using the standard gap in switch SW2. With the switches in position 3, the unit 6, (the circuit of Fig. 2) measures the breakdown of spark-plug. In position 2, the extended gap in SW2 allows any insulation breakdown to be detected. Peak voltage indication may be by a chain of neons across a ladder of resistors in parallel to the measuring capacitor, Fig. 6, (not shown) or by using the capacitor voltage to control the current through a Darlington pair Figs. 3, 4 (not shown).

Abstract: 346,837. Rotary pumps. REES, E., (Representative of REES, E. S. G.), Far Bentlands, Oaken, near Wolverhampton. Jan. 18, 1930, No. 1849. Addition to 324,905, [Class 110 (i), Centrifugal and screw fans &c.]. [Class 110 (i).] Starting, facilitating ; controlling.-A rotary pump, of the type described in the parent Specification, with an impeller provided with circumferential blades having the form of rotafoils, is rendered selfpriming by an arrangement of the suction and delivery pipes so that the pump is always filled with water. The impeller shaft M of the pump is driven by the motor N and the suction pipe I rises to the top of the chamber B. Pipes A, C connect the inlet chamber B to the discharge chamber D. The byepass thus formed may always be open, but so restricted, that only a small portion of the liquid passes through it. In the form shown in the drawing the byepass is controlled by a valve E which is shut during the normal operation of the pump. It is opened manually, by means of the handle F, or automatically, when the delivery pressure reaches a predetermined value; the operating piston G is subject on one side to the pressure in the suction pipe and on the other to the delivery pressure and when the pressure drops after operation of the piston, the spring K restores the parts to their original position. A pipe L is connected to the highest point on the suction side and to a point of strong suction on the pump so that any air may be carried through with the water. The water discharges from the pump into an expanding pipe O opening into a chamber D thus forming an annular expanding passage O<1>.
