Title: Improvements in friction clutches of the single or multiple disc or plate type
IPC: F16D13/70
Filed: 1927-04-05
Abstract: 276,588. Shepherd, L. W. April 5, 1927. Clutches, friction, of the single or multiple plate type. Pins E affixed in the pressure plate C are adapted to be engaged by adjustable screw studs F on levers G rocked by the movement of the operating sleeve H, springs E<1> under the heads of the pressure pins E being compressed on putting the clutch into action and acting to relieve the pressure between the clutch surfaces immediately the sleeve is moved away therefrom. The links g<1> connecting the levers G to the sleeve are preferably arranged as nearly as possible at right angles to the shah to obviate automatic clutching under the action of centrifugal force. As shown, the clutch comprises a friction disc B of fibre, wood or similar material, slidable on keys a on the hub or inside periphery of a shell A, co-operating with the pressure plate C slidable on keys d on the boss of the driving member D, the pins E passing through holes in the driving member. A ring K or a number of segmental flanges secured to the shell A surrounds and is normally clear of the driving member D but engages therewith when the clutch is put into engagement to take up end pressure and prevent the transmission thereof to collars on the shaft.

Class 110(iii) [Also in Group XXIX] An internal-combustion engine, e.g. gas turbine, fuel system comprising a variable-swashplate pump 1 adjusted by a spring-loaded piston 12 subject to the pressure in a chamber 14 connected directly tb the pump outlet and to a control pressure in a chamber 16 connected, through a restricted passage, to the pump outlet and also to leak-off valves 25, 47, has the restricted passage constituted by two restrictions 50, 51 with the leak-off valve 25 connected to a point between the two restrictions and the valve 47 connected directly to the chamber 16. The arrangement permits of a substantial flow through the valve 25 during normal operation of the engine without sacrificing sensitivity of control by the valve 47 which opens only during abnormal running conditions. As shown, two pumps 1, 2 are driven through gearing 6 by a gas turbine engine and discharge into a common fuel delivery pipe 4 having a throttle 5. The valve 25 is loaded by a spring 29 and actuated by an evacuated bellows 31 subject to barometric pressure and a diaphragm 34 subject to the fuel delivery pressure. Two valves 47, one for each pump, are opened by a diaphragm 43 subject to the delivery pressure of a centrifugal impeller 37 upon the attainment of an excessive engine speed. The valves 47 may be operated at slightly different speeds. Specification 577,016. [Group XXIX], is referred to.

Title: Process for the production of tetralin derivatives
Inventor: KES KLAAS
IPC: C07C45/69
Filed: 1962-03-14
Abstract: Acylated tetralins of the formula: <FORM:0948697/C2/1> in which Ac is a lower acyl group, R1 is an alkyl group of 1-5 carbon atoms, R2 is hydrogen or a methyl group in o-position to R1, R3, R4, R6, R7 and R8 are the same or different and represent methyl or ethyl groups and R5 is hydrogen or a methyl group, are prepared by a reaction sequence in which (a) a substituted benzene of the formula: <FORM:0948697/C2/2> and an unsaturated ketone of the formula: <FORM:0948697/C2/3> are reacted to yield a ketone of the formula: <FORM:0948697/C2/4> (b) this ketone is reacted with a Grignard reagent of the formula R7R8CHMgX, where X is a halogen atom, to yield a carbinol of the formula: <FORM:0948697/C2/5> which (c) is cyclized to yield a tetralin of the formula: <FORM:0948697/C2/6> whereafter (d) the tetralin is acylated. In step (a) a saturated ketone of the formula: <FORM:0948697/C2/7> in which X is a halogen atom, may be used instead of the unsaturated ketone, and in step (c) the carbinol may be dehydrated to yield a hydrocarbon of the formula: <FORM:0948697/C2/8> before the cyclization. The reactions are carried out by standard methods. In an example, (a) toluene and mesityl oxide yield 4-methyl-4-(p-tolyl) - pentan - 2 - one which (b) by reaction with isopropyl magnesium bromide, yields 2,3,5-trimethyl -5- (p-tolyl) - hexan - 3-ol; (c) the latter is cyclized to yield 1,1,3,4,4,6-hexamethyltetralin either directly or after dehydration to 2,3,5-trimethyl -5- (p-tolyl)- hexene-2, and (d) the tetralin derivative is acylated with acetyl chloride. Replacement of the mesityl oxide by 3,4-dimethylhex-3-ene-2-one yields, successively. 3,4-dimethyl -4- (p-tolyl) -hexan -2- one, 2,3,5-trimethyl -5- (p-tolyl) -heptan -3- ol, 1-ethyl -1, 3, 4, 4, 6-pentamethyltetralin and 7-acetyl -1- ethyl -1, 3, 4, 4, 6-pentamethyl tetralin. The products have musk-like odours.ALSO:Alkenyl benzenes of the formula <FORM:0948697/C3/1> are prepared by dehydrating the corresponding carbinols of the formula <FORM:0948697/C3/2> The hydrocarbons or the carbinols may then be subjected to ring-closure to yield tetralin derivatives of the formula <FORM:0948697/C3/3> R2 is hydrogen or methyl ortho to R1 which is a C1-C5 alkyl group, R5 is hydrogen or methyl and the remaining R groups are methyl or ethyl. An example is given in which 2,3,5-trimethyl-5-(p-tolyl) - hexene - 2 and 1,1,3,4,4,6 - hexamethyltetralin are prepared, and reference is made also to the production of 1-ethyl-1,3,4,4,6-pentamethyltetralin.

Abstract: In prepn. of fluidised bed material, a core is first formed, using a silicate based material of the desired density, or of a neutral material, preferably perlite or foam glass, by the addition of a vaporising binding material and simultaneous pelletising or forming. A crust is added to the core and the form is dried at temperatures between ambient and 120 deg. By raising the temperature, the crust is baked to become self-supporting. The binding component of the core is evaporated through the crust. Raising the temperature further transforms the core into a glass-like coating on the inside of the crust. Finally, the crust is baked at 1350-1890 deg.C.

Filed: 1980-01-09
Abstract: PURPOSE:To enable to transmit digital modulation wave efficiently by obtaining the predicted signal showing the prediction value of digital signal output from the absolute value circuit after one sampling interval from the output at present time of the absolute value circuit. CONSTITUTION:The digital modulation wave in n-bit per one sampling incoming to the terminal 7, is stored in the shift register 8 and fed to the absolute value circuit 9 for the absolute value. The output of this circuit 9 is delayed by one sampling interval or more at the delay register circuit 10, then it is fed to the adder 12 and added with the signal at present time from the circuit 9. Thus, the output signal of the circuit 12 is fed to the multiplier 13 as the difference signal and it is multiplied with the weighting coefficient from the coefficient device 14. Further, the output from the multiplier 13 is fed to the adder 15, and it is added with the output of the circuit 9 to obtain the prediction signal representing the prediction value of digital signal outputted from the circuit 9 after one sampling interval from the output at present time from the circuit 9. Thus, the transmission of digital modulation wave can be made efficiently.
