Patent GB-398637-A (GB)
Title: Improvements in control mechanism for motor vehicles
Filed: 1932-08-29
Abstract: 398,637. Fluid-pressure brakes. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Aug. 29, 1932, No. 24061. Convention date, Aug. 28, 1931. Addition to 398,635. [Class 103 (i).] In a motor vehicle having a throttle, a poweroperated clutch, and a power-operated brake all controlled by a single operating member, a second member is provided also to control the power for the brake. The second member may be such that the driver can thereby apply the brake directly as well as by the power means. In the construction shown, a pedal 66 controls (1) the throttle 16 by a rod 64, (2) a valve 32 adapted to connect a clutch-operating cylinder 26 to the induction pipe 12 so as to disconnect the clutch, and (3) a similar valve 132 controlling a brake-operating cylinder 126, the latter valve being operated by means of a clamp 162 on the throttle rod 64, a spring 160, and a rod 148. The second control member for the brake is a pedal 80 loosely pivoted on the shaft of a bell-crank lever 24 operating the brake rod 22, the pedal being connected by a wire 84 and spring 260 to the valve 132, so that when the pedal is depressed the valve is operated and the brake applied by the cylinder 126. When the brake pedal is thus depressed it bears against a pin 78 on the lever 24 and thus also applies the brake directly. The accelerator pedal 66 is also arranged to apply the brake directly by means of a thrust-link 76 having a slotted lost-motion connection with the pin 78 of the brake lever. The valve 32 comprises a piston 40, Fig. 2, operated by a wire 48 against the action of a spring 42 so as to cut off admission of air through ports 44 and establish a connection between ports 36, 38 and therefore between the induction pipe 12 and the clutch cylinder 26. This movement of the valve piston to the right is facilitated by a vent 54 in the valve casing and by an inwardly-opening check valve 56 which retards movement to the left for clutch engagement. A friction washer 58 on the valve piston tends to ensure uniformity of movement during the engagement of the clutch. A modification is described in which the accelerator pedal is connected to the brake lever 24 without any lost-motion connection, so that when the brake is operated and the brake lever rotated the accelerator pedal is rocked to close the throttle and disengage the clutch.

Abstract: 660,660. Velocity-moduleted tubes. STANDARD TELEPHONES & CABLES, Ltd. Sept. 15, 1948, No. 24219/48. Class 39 (i). Electromagnetic wave amplifying apparatus, designed to lie between the extremes of sharply tuned apparatus employing cavity resonators and aperiodic travelling wave tubes, comprises a coaxial transmission line having an outer conductor and a plurality of separated annular inner conductors, the said inner conductors being arranged so that each successive pair forms a quarter wave sleeve at a frequency within the amplifying range of said apparatus and providing successive gaps for interchange of energy between electromagnetic waves propagated by said line and an electron beam projected axially through said hollow inner conductors. In one embodiment, Fig. 1, a pair of coaxial transmission lines have a common outer conductor 1 and inner conductors comprising a plurality of stepped cylinders 2 supported by means such as ceramic insulators 5, the portion 3 of one cylinder overlapping the portion 4 of the adjacent cylinder by a distance A -, where A is the mean wavelength to be 4 amplified, and forming a quarter-wave sleeve. The ends of the first quarter-wave sleeves in the direction of wave propagation are separated from one end plate 6 and dividing plate 8 by a quarter-wavelength and a half-wavelength respectively, and the input and output feeders 9 and 10 are positioned a quateer-wavelength from respective end-plates 6 and 7. An absorbent partition 11 is located a quarterwavelength from member 8 to provide a proper termination for the input section. An electron beam passing between electron gun 12 and collector 13 interacts at the inner ends of the quarter-wave sleeves with the waves travelling along the coaxial line, the distance X separating the points of interaction being chosen so that electrons pass the ends of the sleeves at the same phase of the wave. The electron gun and collector may be enclosed in an evacuated glass envelope 14, or the latter may be omitted and arrangements provided for evacuating the complete transmission line sections. In an alternative embodiment, Fig. 5, the centre conductor of the transmission line comprises a plurality of hollow cylinders 15, supported by means such as ceramic bases 17, and forming a plurality of quarter-wave sleeves. The line has a right-angled bend at its input end and a high impedance matching section 23 provided with a reflecting termination 24 through which may be taken the leads 25 to the electron gun 12 and collector electrode 13 of the tube 20 which is mounted on an insulating member 26 fitting into portion 22 of the centre conductor. Alternatively, the line may be terminated as in Fig. 1 and input and output loops provided. The glass envelope of the tube 20 may be omitted and the beam projected directly through the openings in conductors 15.

Title: Improvements in and relating to the manufacture of cellulose ethers
IPC: C08B11/08
Filed: 1929-08-14
Abstract: Specially-prepared, water-soluble, cellulose glycol ethers are used as emulsifying agents.ALSO:Cellulose glycol ethers soluble in water, but insoluble in common organic solvents, e.g. benzene, ether, acetone, chloroform, are produced by mixing matured alkali cellulose with powdered caustic soda and ethylene chlorhydrin and heating the mixture.  In an example, cotton linters or wood pulp is mercerized with 18-25 per cent caustic soda solution for a period up to 24 hours, preferably one hour; the alkali cellulose is pressed to 2-4 times the weight of the cellulose, shredded, and matured for about 48 hours at 15-35 DEG  C., and is then mixed with 1-1 1/2 parts of finely powdered caustic soda and 1 1/2 -2 parts ethylene chlorhydrin; and the mixture is heated on a water-bath or in a steam-jacketed kettle for about 8 hours.  A further 1/2 -1 p  part of powdered caustic soda and 1 1/2 -2 parts ethylene chlorhydrin are added and the mixture again heated for 8 hours, after which 1/2 -1 part ethylene chlorhydrin is added and heating continued for 8 to 10 hours.  The yellow, sticky reaction mass is made into a viscous solution with water and dialyzed till free from alkali and chloride, after which the ether is precipated with acetone, filtered and washed with acetone followed by ether. The product is a white, fibrous material, readily soluble in water giving a very viscous solution. It is useful as a thickening agent for textile printing, as a fixing agent for printing, and as an emulsifying agent and for sizing yarns. In a second example, the alkali cellulose is matured up to 96 hours and the quantity of powdered caustic soda is reduced.  The reaction product is malaxated with alcohol and filtered and after several such treatments the product is finally washed with ether.ALSO:Specially prepared, water-soluble, cellulose glycol ethers are used as a binding-agent, preparation for sizing yarn &c.
