Title: Process for the preparation of amino-alkoxy-diphenyl derivatives
IPC: C07D295/092
Filed: 1938-11-23
Abstract: 521,575. Diphenyl derivatives. ELLIS, L. S. E. (Soc. des Usines Chimiques Rhone- Poulenc). Nov. 23, 1938, No. 34077. [Class 2 (iii)] Aminoalkoxy derivatives of diphenyl of the formula in which Rand R<SP>1</SP> represent hydrogen or alkyl or together signify a polymethylene chain, are prepared by (1) treating an alkali metal compound of a hydroxydiphenyl with a chloralkylamine, or (2) first reacting the same alkali metal compoundwith an alkylene dihalide, and treating the product with ammonia, a mono- or di-alkylamine, or a cyclic amine. The products possess therapeutic properties. According to the examples, (1) diethylaminoethoxy-, piperidinoethoxy- and diethylaminopropoxy-2- diphenyl are prepared by reacting 2-hydroxydiphenyl with 1-chlor-2-diethylaminoethane, chlorethylpiperidine and 1-chlor-3-diethylaminopropane respectively in presence of sodium alcoholate ; diethylaminoethoxy-3 and 4- diphenyl are similarly prepared ; (2) dimethylaminoethoxy-2-diphenyl is obtained by treating 2-hydroxydiphenyl with ethylene dibromide in the presence of sodium alcoholate and reacting the 2-bromethoxydiphenyl so formed with dimethylamine ; similar products are prepared by replacing the dimethylamine by ammonia or ethylamine or by using trimethylene dibromide instead of ethylene dibromide.

Title: A Method and an Apparatus for the Production of a Control Signal for Automatically Controlled Devices
IPC: G05B1/02
Filed: 1967-07-26
Abstract: 1,199,174. Automatic control. OSTERREICHISCHE STUDIENGESELLSCHAFT FUR ATOMENERGIE G.m.b.H. July 26, 1967 [July 26, 1966], No.34226/67. Heading G3R. Electrical signals corresponding to the magnitude of a process variable are produced periodically and compared with a desired magnitude, any errors greater than a predetermined magnitude being effective to correct the variable but any greater than a higher predetermined magnitude being rendered ineffective for control purposes. As shown, a digital signal corresponding to the magnitude of a variable is produced at 2 and periodically compared at 3 with a desired value set at 4. Successive errors enter a store 5 and are compared at 6 with predetermined limiting values so that, if one limit is exceeded, a signal is applied from a generator 7 through a store 8 to cause a fixed or variable adjustment of a member 21 which corrects the variable and operates an indicator 22. At the same time a signal from generator 7 is applied through a logic circuit 11 to a number of stores 10 which respectively store an initial excessive error and the amounts by which, in a given period, any subsequent errors exceed the initial error. These stored values are summed over the period by an integrator 13 and, if the sum exceeds a predetermined value determined by a unit 15, an additional correction is applied to store 8. The integral is periodically reduced at 17 and the correction is made inversely dependent on the period of integration by a unit 18. If the error exceeds a second higher limit in unit 6, indicating a fault in the control system or the controlled process, operation of member 21 is prevented. The number of times this occurs in a given period is counted at 19 so that an alarm 20 is operated if the number is excessive. Control of thickness and the use of optical and radio-active detectors are referred to.

Class 80(2) [Also in Group XXV] A knob fastener for assembly on to the end of a shaft 12 passing through a motor car dashboard, comprises a first knob portion 16 having an aperture 24 to receive the shaft and a channel shaped member 32 extending therefrom, a fastening device 20 assembled in the upper part 36 of the channel to engage the inserted shaft, a peripheral wall 22 on the knob portion 16 surrounding the annular channel member, and a second knob portion 18 snapped into the first knob portion. The fastening device 20 is a metal clip having a downwardly extending flange 46 with a hole 48 through which passes the end of the shaft, an edge 50 of the hole engaging a slot 14 in the shaft. A bent up tongue 42 of the fastening device engages a stop 44 on the knob portion 16. The body portions 16, 18 are made from moulded plastic material and are provided with interengaging lips 28, 54 which snap together. A cylindrical projection 56 in the knob portion 18 receives the end of the shaft 12. To assemble the device, the knob portions 16, 18 are snapped together, the fastener 20 placed in the upper channel 36 so that the tongue 42 engages the stop 44, and the knob pushed on to the shaft till the edge 50 of the fastener 20 engages the slot 14. The knob is then retained on the shaft against both rotative and push-pull forces. To release the knob from the shaft, either the knob portion 18 is unsnapped from the portion 16 and the tongue 42 released from the stop 44, or the flange 46 of the fastener 20 is raised to disengage the edge 50 of the fastener hole 48 from the slot 14.

[Class 80 (ii).] An automatically variable-speed gear of the kind comprising in combination a multiple free wheel in which the speed ratio is varied by the eccentricity of the driving member in respect to the driven member, and an epicyclic gear train, comprises a drum 2 driven by the shaft 1 through a number of pairs of slider cranks 11, 11<a>, and free wheel devices 27, 26, 23, rotatably mounted in supports 32, 33, 34, 35, which can swing about a secondary shaft 3 to vary the eccentricity and hence the speed ratio of the drum 2 with respect to the shaft 1. The drum 2 is geared to the shaft 3 by wheels 4, 5, and clutch 36 and so to the planet carrier 8 of the epicyclic gear of which the annulus 12 is driven direct from the shaft 1 and the sun is connected to the driven shaft 9. The torque transmitted by the drum to the secondary shaft tends to rotate the drum about the said shaft which movement is controlled by a helical spring 42 on a shaft 41 connected to the drum by levers 51, 48, so that for every value of the torque transmitted the drum takes up a corresponding position and varies automatically the speed ratio of the gear. The gears 14, 39, and clutch 37 provide a reverse drive independent of the multiple free wheel device.

Abstract: 872,054. Fuel injection pumps. BESSIERE, P. E. Nov 12, 1957 [Nov. 20, 1956], No. 35260/57. Class 102(1). A self regulating fuel injection pump comprises a pump piston 2 reciprocating in a cylinder 1 having a feed conduit 4 in which there is interposed a reciprocable member 9. The member 9 is loaded by a spring and is acted upon by a liquid to move the member to close the feed. In the embodiment shown the piston 2 after closing the port 3 delivers fuel through passage 14, 14a and past valve 15 to act on the member 9 causing it to close the feed conduit 4. At the commencement of the return stroke of the piston 2 the member 9 begins its upward movement under the action of the spring 18 and drives the liquid past a throttle 16 in passage 14b to the cylinder 1. As the speed of the piston 2 increases there comes a time when the member 9 does not complete its return stroke before the next delivery stroke of the piston 2 and consequently the feed of fuel to the cylinder when the port 2 is opened is throttled and reduced, this reduction increases as the speed of the piston 2 increases. In modification the passage 14 may open into the cylinder immediately above the port 3 or the feed passage 4 may lead to the passage 14. In a further modification the liquid actuating the member 9 may be supplied by a separate pump piston moving in synchronism with the piston 2 or may be formed on the piston 2. Specifications 861,754 and 872,053 are referred to.
