Title: Preparation of chlorocyanuric acids
Inventor: ALLCOCK HARRY REX
IPC: C07D251/36
Filed: 1959-01-15
Abstract: <PICT:0930643/III/1> Chlorocyanuric acids are prepared by passing a solution of a cyanurate, or cyanuric acid in an alkali, the solution having a pH above 7, in countercurrent to a stream of chlorine, such that the pH of the liquid effluent has a pH in the range 3 to 5.  The reaction is carried out in a column such that the ascending chlorine bubbles through a series of pools of the descending cyanurate solution, for example a bubble cap column, as shown in the Figure, or a sieve-plate column.  The concentration of the cyanurate solution is preferably 2-5%, and its temperature when introduced -10 DEG C. to +25 DEG C.  The chlorocyanuric acid product, which leaves the column as a suspension, may be recovered by centrifuging, decanting, or filtering.  To obtain trichlorocyanuric acid, trisubstituted salts are used as starting materials, and for the dichlorocyanuric acid, disubstituted salts.  Mixed salts may also be used.  The column is preferably transparent to ultraviolet radiation, which favours the desired reaction.  Specification 634,801 and U.S.A. Specification 2,607,738 are referred to.

Title: Improvements relating to fluid-pressure operated motors and to windshield cleaners operated thereby
IPC: B60S1/06
Filed: 1943-02-01
Abstract: 563,252. Semi-rotary motors. TRICO PRODUCTS CORPORATION. Feb. 1, 1943, No. 1660. Convention date, Feb. 2, 1942. [Class 110 (ii)] To maintain the wiper stroke uniform a fluid pressure (or suction) operated motor for driving a, windsoreen wiper blade, has a valve to reverse the pressure differential on the two sides of the piston and speed-responsive means whereby the functioning of the valve is advanced so as to shorten the stroke of the piston as the speed increases. A valve 7 oscillates over a valve seat 8 having suitable ports 9 to direct the working fluid to either side of the piston 2. Legs 10 on the valve limit its travel by coacting with a stop ring 11. A part 13 (termed a picker) has a hub 14 pivotally mounted on a shaft 3 and has a seat 15 held by a hanger 16 to which one end of a snap spring 17 is hung. The lower end of the spring engages an eye 18 in a valve-pressure plate 19 which bears on the valve 7 to press the latter lightly on to its seat. Stops 25, on the picker, alternately engage a governor actuator 26 so that the picker is carried across its dead-centre position with respect to the spring 17, the latter then moving the picker independently of the actuator and reversing the valve 7. A seat 29, on the actuator, normally rests on the shaft 3 under the urge of a spring 30, which may be adjustable. A weighted disc 32 is rotatably mounted on a shaft extension 31 and is provided with a pair of cam lugs 33 which normally engages a pair of shoes 34 on the actuator to establish a yieldable driving connection between the shaft 3<1> and the disc for oscillation. During fast operation of the motor, the inertia of the disc 32 will carry through from the preceding stroke into the beginning of the following piston stroke so that a lug 33 lifts a shoe 34 and thus the actuator 26. A stop 25 on the picker then engages a wider part of the actuator, thus shortening the stroke of the picker and effecting an earlier shifting of the valve 7.

Abstract: 776,764. Television. SOC. NOUVELLE DE L'OUTILLAGE R.B.V. ET DE LA RADIOINDUSTRIE. Jan. 22, 1954 [Jan. 24, 1953], No. 1984/54. Drawings to Specification. Class 40 (3). At an intermediate point in a television transmission channel a " negative" image is produced and then scanned to produce corresponding signals. This arrangement improves the contrast of the finally reproduced image since the non-linear response of the final picture tube is, in effect, neutralized by a similar response in the intermediate picture tube. " Shading " effects are also wholly or partly corrected since the shading effect of the intermediate pick-up tube is, in effect, opposite to that of the main camera tube. Complete correction of shading effects may be assured by providing a black border surrounding at least two non-parallel sides of the intermediate image produced on the pick-up tube. The arrangement may be employed in film recording apparatus. Specification 776,763, [Group XL (a)], is referred to.
