Title: Continuous Casting Process and Apparatus
IPC: B29C39/42
Filed: 1966-09-20
Abstract: 1,168,084. Continuous casting. SWEDLOW Inc. 20 Sept., 1966 [28 Sept., 1965], No. 42039/66. Heading B5A. A continuous polymeric sheet, of e.g. an acrylic resin, is cast between moving surfaces, the path of which is inclined to the horizontal at such an angle that the hydrostatic pressure of the working material is sufficient to keep the surfaces separated to the required extent. The inclined path may be straight, angled or may follow the " natural curvature " of the surface as is disclosed in Specification 1,168,083. In the embodiment illustrated in the Figure, the material is cast between two variable-tension endless steel belts 50 and 51 the co-operating runs of which are inclined in a straight line to the horizontal and converge slightly so as to accommodate the shrinkage of the working material which occurs on curing. The cast material is first heated to cure it by flooding the belt with hot water from pipes 65, 66 and 68 and then heated to post cure it by hot air blowers 80. Alternatively, curing may be effected by spraying the belts with hot water.

A fluid flow control valve is provided with apparatus for operating it to a closed position after a predetermined period of opening. The apparatus as applied to a rotary valve, comprises a plate 14 secured to the valve spindle 12, which carries a bob-weight 25, the plate being provided with notches 15, 16, 17 and 18 and carrying a pivoted pawl 27. A first lever 30 pivoted at 31 and having a cam 29 carries a bobweight 37 at one end and pin 32a at the other which engages a slot of a head 33, mounted on rods 34, 35, of a timing device 36. A second lever 38 pivoted at 39 and having a bobweight 40 is provided with a first arm 41 whose end bears on the head 33 and a second arm 43 having a detent 44. When the valve and plate 14 is rotated in a counterclockwise direction, the pawl 37 acts through cam 39 to move the head 33 to the dotted line position to set the timing device. The plate 14 is rotated to the required valve position and the detent 44 engages the appropriate notch 16, 17 or 18. The shapes of the notches and detent 44 allow the detent to ride out of notches 16, 17, for example if the position corresponding to notch 18 is required. At the end of the set time, the head 33 rises to lift the detent outward of the notch and the bobweight 25 falls, thus closing the valve. The bobweights may be replaced by suitable springs.

Filed: 1967-09-22
Abstract: 1,161,951. Telegraphy. SIEMENS A.G. 22 Sept., 1967 [23 Sept., 1966], No. 43145/67. Heading H4P. A telegraph pulse distortion measuring circuit displays the distortion value of a pulse on an oscilloscope until arrival of the next pulse; at the occurrence of a pulse edge the count on a counter is fed to a store which controls the display. In one embodiment, Fig. 2 (part shown), the start bit of a telegraph signal fed in at M enables cyclic counter Z1 to count clock pulses from unit TG. There may be 100 pulses in each bit period. Each transition in the signal enables gate G to pass the instantaneous count on Z1  to store S1 so this stores an indication of the percentage lead or lag of the transition. The indication is converted to analogue form by DAU, the analogue signal controlling the X- deflection of the C.R.T. at a corresponding level until the next transition occurs. Each transition also causes oscillator G to produce an alternating signal which controls the Y-deflection and has an amplitude dependent on the polarity of the bit so that it can be seen whether the distortion value relates to a Mark or a Space. Counter Z2 stops the clock pulse unit TG when Z1 has cycled a selected number of times depending on the number of bits in a signal. In a second embodiment, Fig. 3 (not shown), which is generally similar to that described above, the circuit is elaborated to allow the selective measurement of start-stop, synchronism, and bit length, distortion.

IPC: C23C8/36
Filed: 1963-11-01
Abstract: In a method and apparatus for the surface hardening of bodies e.g. of steel by gaseous treatment, e.g. with nitrogen or ammonia or with the hydrides of silicon, boron or phosphorus the bodies are placed in a container which is rotated at such a speed or range of speeds that they are held against the container wall by centrifugal force but move continuously or intermittently in relation thereto so that the body surfaces will be uniformly hardened.  In a preferred embodiment the bodies are subjected to a glow discharge during treatment, while prior to hardening they may be cleaned by vacuum treatment or treatment in atomic hydrogen in the apparatus.  In the particular apparatus illustrated in the Specification the container (7) for the parts to be treated, which is adapted to be water-cooled, is rotatably and gas-tightly mounted in a treatment vessel (18). Treatment gas is introduced to the vessel (7) through a pipe (16) and leaves through a centrally disposed conduit (10) which extends downwards into the container. This conduit also functions as the anode for a glow discharge while by connection through the treatment vessel (18) the surface of the container (7) is caused to act as cathode.  The invention is particularly concerned with the treatment of ball-pen cages and balls.

Title: Ozone generating apparatus
IPC: C01B13/11
Filed: 1975-10-27
Abstract: The system comprises an ozoniser (1) and an adsorption dryer with at least two chambers (5, 6) which can be switched to adsorption and desorption. The gas fed to the ozoniser first flows through that chamber (5 or 6) which is ready for adsorbing the humidity and is thus dried. In order to regenerate the adsorbent in the chamber (6 or 5) switched to desorption, this chamber has part of the ozonised gas passed through it, which gas is discharged from the ozoniser (1). Then the humidified ozonised gas is passed on to its final use. The system is connected in such a way that the gas to be ozonised always enters the ozoniser on the same side, so that gas always flows through the ozoniser in the same direction, independent of the switching state at any given time of the chambers of the adsorption dryer. This measure makes it possible to optimise, on the one hand, the cooling and thus also the efficiency of the system, while, on the other hand, the complexity of the construction is considerably reduced. <IMAGE>
