Title: Brake assembly
IPC: F16D65/09
Filed: 1972-03-28
Abstract: 1401661 Internal shoe-drum brakes; automatic adjustment AUTOMOTIVE PRODUCTS Ltd 19 March 1973 [28 March 1972] 14457/72 Heading F2E The shoes of an internal shoe-drum brake have an operating means such as a cam between one pair of adjacent shoe ends and a pair of screwthreaded fulcrum tappets 21, 22 respectively engaging the opposite shoe ends; the tappets 21, 22 are spread apart to adjust for shoe lining wear by an arrangement comprising a ratchet wheel 9, a driving pawl 10 rockable on a main lever 13 and a spring-loaded secondary lever 26 pivoted on the main lever 13 and connected to the shoe operating means so that, at each brake operation, the secondary lever 26 is moved in opposition to the load of the spring 28 and tends to move the main lever 13 in a direction causing brake adjustment but pivots idly on the main lever 13 if the load applied to the fulcrum tappets 21, 22 by the shoes and opposing the adjusting movement is greater than the spring load on the secondary lever 26. The fulcrum tappets 21, 22 are held against turning by the engagement of the webs of the respective brake shoes with slots 23, but they are engaged with rotatable nuts 3, 4 in a stationary cylindrical housing 2 which nuts 3, 4 have outer collars 5, 6: between the nuts 3, 4 is a floating driving plate 7 having dogs 8 engaging notches in the nuts 3, 4 and serving as a coupling for the two nuts 3, 4 to turn together. The ratchet wheel 9 is carried fast by the nut 4 and can be turned by the driving pawl 10 in anti-clockwise direction as seen in Fig. 3. A lug 14 on the main lever 13 freely enters a locating slot 15 in the pawl 10 so that the pawl 10 can rock on lever 13 to engage the wheel 9 under the load of a tension spring 16 anchored to a stud 17 on the housing 2. The spring 16 also biases the lever 13 towards stud 17. The main lever 13 is pivoted on a bush 19 attached to the housing 2 while the secondary lever 26 is pivoted about a trunnion stud 27 on the main lever 13 and is linked to the operating means by a pull rod 25. The spring 28 is anchored between notches 29, 30 on levers 13, 26 respectively, and under the action of spring 28 a shoulder 31 on lever 26 abuts against an edge 32 of lever 13. The spring 28 acts to restrain the secondary lever 26 to move as one with the main lever 13 under the pull of rod 25 so long as pawl 10 can engage and turn ratchet wheel 9 despite the load of nut collars 5, 6 against the housing 2 under the action of the shoes rocking on tappets 21, 22. This load is small until the shoes contact the drum whereupon it outweighs the pull of spring 28 which yields to allow the secondary lever 26 to move idly and the main lever 13 and pawl 10 to retain their positions. On release of the brake operating means the lever 16 engages stud 17 and the pawl 10 engages the adjacent tooth of ratchet wheel 9.

A constant velocity-ratio universal joint comprises torque-transmitting generally barrelshaped rollers 14 disposed between pairs of registering generally axially extending grooves 18, 34 respectively in the outer and inner surfaces 16, 32 of inner and outer members 10, 12, and cams 25 fast in the bottoms of the inner member grooves 18 engage radially inwardly facing spherical recesses (48) in the rollers to position the latter in a plane bisecting the rotational planes of the members 10, 12. The inner member outer surface 16 is spherical with meridian grooves and engages the outer member inner surface 32 which may be spherical also or, as shown, to permit relative axial movement between the members, cylindrical. The grooves 18, 34 are equally spaced and have flat or slightly curved side walls. The rollers comprise oppositely directed frusto-conical surfaces, alternatively the surfaces may be slightly curved. The groove width is slightly greater than the roller diameter for contact on one side only, thereby avoiding rubbing on the other side. The rollers are bored merely to facilitate manufacture and hardening. The cams may be integral with the inner member or, as shown, flat plates fitting closely in slots 24 in the bottom of the grooves 18 and confined as by spring snap rings 26. The radially outer surfaces of the cams have central convex portions (56), with a radius approximately that of the roller recesses (48), and straight end portions (58) into which the portions (56) blend.

Title: Heat treatment apparatus and method

Filed: 1973-03-27
Abstract: 1425742 Automatic control of micro-wave systems L'OREAL 27 March 1973 [27 March 1972] 14740/73 Heading G3R [Also in Divisions H3-5] The matching of a micro-wave cavity resonator to a coaxial feeder, or of the feeder to a microwave generator, is carried out by sensing the power flow and automatically adjusting a coupling component accordingly to obtain the best transfer of energy. In one embodiment the current flow in a feeder 34 is sensed by connecting a lamp 37 across a resistor 36 so that when no current flows, and thus no energy is transferrred, the lamp does not light and photo-cell 38 has no output thus leaving relay 39 in a closed state when motor 40 drives the moving plates of a variable coupling capacitor 33 to adjust the matching. When current does flow in feeder 34 lamp 37 lights and the output of photo-cell 38 is amplified to change relay 39 to an open condition when the motor 40 is deenergized. In a second embodiment, Fig. 15 (not shown), the standing waves on the feeder are detected by two coils connected in a frequency selective network to two balanced resistors at the input of an operational amplifier, so that unbalance of the signals at these resistors controls a motor to adjust a capacitor as before.

Abstract: 593,122. Electric clocks. TRUVOX ENGINEERING CO., Ltd., and THILO, H. A. June 12, 1945, No. 14903. [Class 139] In an electric clock the transmission gearing between the synchronous motor shaft and the seconds hand consists solely of a pin mounted slightly eccentrically with respect to the driving shaft adapted to engage the teeth of the seconds wheel so as to give a large step down of gearing at a single stage. As shown in Figs, 2, 5 and 6, a synchronous electric motor 13 has an armature 10 mounted on a shaft 14 rotated at 120 revs. per minute. The shaft 14 drives by means of an eccentrically mounted pin 15, Fig. 5, a 120 toothed seconds wheel 16 on the shaft 17 of which is mounted a seconds disc bearing the numbers of the seconds which numbers are viewed through an opening in the dial. A spring pawl 25 ensures correct " stepping on " of the seconds wheel 16. The drive from the seconds wheel 16 to the 120- toothed minutes wheel 19 is also by means of an eccentric pin 18 on the shaft 17 which in this case is shaped to act like a Geneva stop mechanism to ensure correct " stepping on " of the minutes wheel. There is just an ordinary drive between the minutes wheel and the hours wheel.

Title: Improvements in and relating to processes for purifying sulphuric acid
IPC: A01F15/10
Filed: 1934-05-17
Abstract: Sulphuric acid is purified by passing hydrogen sulphide through the acid until the impurities are completely precipitated, filtering the acid, heating the filtered acid to a temperature above 80 DEG  C., and again filtering it.  The filtration steps may be carried out in a pressure filter of the kind described in Specification 322,091, [Class 46], using auxiliary filtering agents such as kieselguhr and fullers earth; the filter cake after being broken up can be repeatedly re-used.  The acid may be cooled before the second filtration.  If the acid to to be treated contains sulphur dioxide, this should be removed by blowing air or another inert gas into the acid prior to the process.  The process is particularly applicable to acid of a concentration of greater than 70 per cent and removes impurities such as arsenic, selenium and copper.  Examples are given.
