IPC: B23P15/10
Filed: 1964-08-14
Abstract: 1,060,225. Making pistons. A.M.O. (AVIATION, MARINE, OUTILLAGE). Aug. 14, 1964 [Sept. 5, 1963], No. 33388/64. Heading B3A. [Also in Division F2] In a process for manufacturing an aluminium alloy piston having an annular coolant duct, a plurality of inwardly directed recesses are formed in the mass of the piston into which mechanical or electrical machining means are inserted to join up the recesses and form the duct, the recesses being finally sealed by segments fitted thereinto. The recesses may be machined inwardly from the piston skirt. from the crown or from the interior of the piston. The electrical means may comprise spark erosion apparatus and the segments may be welded in position if the weld is in an area not subjected to high temperature. Normally the segments are a shrink fit or may be welded when located in a zone of the piston which is not subjected to high temperature.

Title: A method of treating various diseases by sleep and a device for the realisation of the method
IPC: A61N1/34
Filed: 1959-10-02
Abstract: 930,116. Electrotherapeutic apparatus. J. B. HOODYI, V. P. KOOTINOV, and V. S. BULBA-POPKOV. Oct. 2, 1959, No. 33446/59. Class 81 (2). Electrotherapeutic apparatus for inducing sleep in a patient comprises means for producing square waves superimposed on a D.C. component. In the basic circuit two valves 5, 5, connected as a multivibrator, produce pulses which are passed to a third valve 6 which limits the voltage peaks and so provides an output which is of a substantially square waveform. This is passed through an output valve 7 where the D.C. component is added by a tapping on a potentiometer connected in the anode circuit at 18. The final output is passed through a meter 12 to electrodes for application to the patient. Coarse adjustment of the pulse frequency is provided by varying the circuit capacitance by a switch 9 while fine adjustment is made by potentiometer 8. Variation of the time constant, to determine the pulse width, is obtained by potentiometer 10 and alteration of the direct current component is effected by changing the bias of valve 7 by means of potentiometer 11. Additional parallel output stages may be used to supply further patients.

Abstract: The exterior rear-view mirror described in the main patent, in which a mirror glass support is fastened on a base part by means of an intermediate part in such a way that it can be adjusted by hand to an optimum rear view position, was to be further developed in such a way that it can also be equipped with a mirror glass support which can be adjusted remotely electrically by means of control switches or feed cables without fundamental changes to the base part or the intermediate part. An electrically insulating support part (37, 41) is therefore now attached in each case inside the longitudinal guides (33, 22) provided on the intermediate part and on the base part (3 and 2); both support parts are provided at regular intervals with contacts (39, 43) serving for the connection to feed cables and discharge cables (44 and 40). <IMAGE>

Title: Improvements in or relating to cold cathode electron discharge tubes
IPC: H01J35/06
Filed: 1935-12-06
Abstract: 463,210. Discharge apparatus. ROGOWSKI, W. Dec. 6, 1935, No. 33878. [Class 39 (i)] A cold-cathode tube, such as a cathode-ray tube or a R÷ntgen-ray tube, has means for producing rotation-symmetrical fields which control the intensity of the beam in a region in which the electron velocity is low before the beam is deflected. Electrostatic or electromagnetic fields may be used. A hollow cold cathode 1, Fig. 2, houses a control electrode 6 and preferably an anode 7. An anode 2 is provided. The cathode may consist of an openended box which is closed by the electrode 6 or may be curved or plane. In another form, a tube is provided with a cathode 1, Fig. 6, anodes 2, 10, 11, perforated diaphragms 9 which form part of a box in which the control electrode 6 is housed. An electrode 8, which is negative with respect to the cathode, provides a rotation-symmetrical counter field to retard, and also to concentrate, the electrons before they reach the control electrode. To compensate for the variation in the anode potential in dependence upon the variation of the current, the perforated anode 2, Fig. 7, is connected through a resistance 13, and preferably a perforated anode 16 is connected directly to the voltage source 14. The anode potential may be controlled through an electron tube in dependence upon the voltage drop across the resistance 13. The tube may be operated by means of an auxiliary discharge.

Abstract: 1482116 Lubricating differential gearing EATON CORP 1 Aug 1974 [6 Aug 1973] 33930/74 Headings F2A and F2D An axle mechanism is provided with a lubrication system including four different lubrication channels such that lubricant is directed to the differential irrespective of the direction in which the mechanism is driven, and irrespective of the orientation of the mechanism. The axle mechanism has an axle housing 12 (which can be mounted in one of two positions) having an opening into which a differential carrier housing 10 mounted on the axle housing extends. The carrier housing has a drive pinion gear 14, a ring gear 16 engaging the drive pinion gear, and a differential 15 is secured to the ring gear. A pair of output members 46 extend from the differential through bearings 32, 33 which mount the ring gear and differential on the carrier housing. The axle housing and carrier nousing constitute a lubricant sump in which a static lubricant level is established such that the ring gear, drive pinion and differential are at least partially submerged. A lubricant duct 81 in the differential communicates with the channels through which lubricant flows having been picked up from the sump by the ring gear 16 or drive pinion gear 15 and directed to the channels by director members (83, Fig. ], not shown) and specially shaped walls (66, 70, Fig. 4, not shown) within the two housings, the channel to which lubricant is directed being dependent upon the orientation of the mechanism and the direction of drive. The axle mechanism, being suitable for mounting in a given position or upside down, may thus be used for either forward or rear driven axles.

Abstract: 1,269,632. Welding by pressure; brazing. BURNLEY ENG. PRODUCTS Ltd. 14 April, 1969 [6 May, 1968; 16 May, 1968 (2); 17 July, 1968], Nos. 21441/68, 23207/68, 23208/68 and 34136/68. Heading B3R. In a unit comprising a first metal sheet 11, a second metal sheet 14 and a cellular metal core 12 between the sheets, the first sheet 11 is welded to attachment elements 15 formed on the core and the second sheet 14 is brazed to the core, the brazing material extending into the corners of the cells of the core but not reaching the first sheet. The unit may form an acoustic panel for silencing a gas turbine engine or a heat resistant tubular element for use in association with the hot end equipment for exhaust gases of such an engine. Metal strips are spot welded together to form the cellular core 12, the strips being plain as shown or corrugated or fluted, and having discontinuous flanges 15 on one edge interrupted by cut-outs 16. The flanges are spot welded to the metal sheet 11, which may be formed of metal mesh filled with metal fibrous material, brazing alloy is applied to the junction of the strips at the corners of the cells 13 at positions remote from the flanges 15 and a thin dispersion of brazing alloy is also applied to the face of the metal sheet 14, the sheet 14 is optionally locally welded to projections 19 formed on the core 12 and the assembly is heated in a furnace to braze the sheet 14 to the core 12. During heating brazing alloy flows along the edges of the strips remote from the flanges 15 and along the corners of the cells towards the cut-outs 16 but without contacting the sheet 11. The ends of the strips forming the core, remote from sheet 11, may also be formed with flanges to facilitate brazing. Corrugations in the strips forming the core permit bending of the strips when a curved panel is formed. In a curved panel a continuous metal ribbon may be brazed to the sheet 14 between cells which may become separated or mismatched. Although the cells may be of equilateral diamond shape they may be formed by abutting antiphase sinusoidal strips or the strips may provide circular cells. Instead of flanges 15 to permit spot welding projecting teeth may be provided to facilitate welding to sheet 11. Instead of providing cut-outs 16 the comers of the cells may be stopped off by surface treatment to prevent brazing material flowing on to the sheet 11.
