Patent GB-909220-A (GB)
Title: Titanium dioxide pigment particles
Inventor: MYERS MYRON LEWIS
IPC: C09C1/36
Filed: 1960-09-30
Abstract: Titanium dioxide pigment particles are coated with at least 0,01% based on the dry weight of the pigment of a salt, soluble in water to the extent of at least 1% by weight, of a tertiary amine with an organic acid, the acid having a solubility between 1/20 % and 2% by weight in water at 20 DEG C. in order to improve the dispersibility in surface-coating compositions after compaction and storage.  The pigment may be coated by leading the tertiary amine salt and the pigment into a fluid energy mill, or by dissolving the salt in water or an organic liquid, and adding the solution to a slurry of titanium dioxide pigment.  It is preferred to add the amine salt to the slurry resulting from the hydroclassification step to which pigment is subjected to remove oversize (>4n ) particles.  The slurry is dewatered and dried and passed through a fluid energy mill.  The amine salts may be prepared by mixing a tertiary amine and an organic acid in stoichiometric proportions.  Specified acids are 2,4-hexadienoic acid, octadecyl sulphonic acid, cinnamic acid, adipic acid, 2-ethyl hexanoic acid, benzoic acid and the diester of phosphoric acid with two mols of 2-ethyl-1-pentanol.  Suitable amines specified are N-methyl morpholine, pyridine, tribenzylamine, triethylamine, 2-methyl pyridine, 4-picoline and triethanolamine. The grades of titanium dioxide which may be coated include those containing conditioning agents such as alkali and alkaline earth metal salts, brighteners and rutile converters, e.g. antimony and zinc salts extending agents such as calcium sulphate, barium sulphate and lithopone and agents for improving the colour and chalk resistance of the pigment, e.g. oxides and hydrous oxides of aluminium, zirconium, titanium and silicon.

Title: Cover latching mechanism for dishwashing apparatus
IPC: A47L15/42
Filed: 1955-11-24
Abstract: 797,900. Latches. GENERAL ELECTRIC CO. Nov. 24, 1955 [Nov. 30, 1954], No. 33735/55. Class 44 [Also in Group XXIII] Relates to a latch for the lid of the tub of a dishwashing machine (see Group XXIII). Referring to Fig. 5, the latch mechanism is carried on a mounting plate 20. The latch 22 is pivoted on the plate 20 at 23 and has a cam portion 24 and hook portion 25. Also pivotal with the latch 22 on the pivot 23 is a latch arm 26 engaging in an opening in one side flange 32 of a slide member 27 also having a side flange 33. The slide 27 has slots 30, 31 engaging pins 28, 29 on the plate 20 and is urged to the position shown against a stop 36 by a spring 35 disposed between the pin 29 and a tab 37 on the slide. Pivotal on the pin 29 is a trip lever 38 having an arm 39 engageable between the flanges 32, 33, an arm 40 engageable with a spring blade 41 of an interlock switch 42 in the machine circuit and an adjustable arm 44 carrying a cam follower 43. When the lid is closed a catch 21 moveable between fixed guides 23a, Fig. 3, engages the cam 24 to pivot the latch 22 so that the hook 25 engages and locks the catch and the arm 26 urges the slide 27 to the position shown in Fig. 3. where it is retained by the trip lever arm 39 engaging the slide flange 33 under the urge of the switch spring 41. Moreover, the switch 42 is then closed to prepare the electrical circuit of an impeller motor. A manual control knob 45, Fig. 7, is now turned so as to rotate a shaft 17 and sprocket 18 and thence by a chain 19 and sprocket, a timer motor shaft which is thereafter rotated in known manner by its motor to rotate the knob through 180 degrees and cause a washing and rinsing cycle to be performed. Coaxial and moveable with the knob 45, Fig. 7, are a pair of cams 46, 49 having pairs of projecting portions 47, 48 and 50, 51 respectively. As the knob rotates to complete the cycle of operations one of the portions 47, 48 engages the cam follower 43 and trips the lever 38 so that slide moves to the position shown in Fig. 5, wherein the lid is released. During these operations, the knob 45 has an axial position relative to the shaft 17 as indicated in Fig. 7 a detent spring 54 then engaging a groove in the shaft. If the knob is moved inwardly on the shaft the detent engages another groove on the shaft and the cam 46 engages an inclined portion of the cam follower 43 to trip the lever 38. The slide is prevented from engaging the stop 36 by engaging the cam surface 49, as described with reference to Fig. 6 (not shown) and the catch 21 is not released from the latch hook 25: On retracting the knob and cams however, the slide can move to itsstop and the lid is then released. The inward movement of the knob however causes the switch 42 to be opened so that the impeller motor is de-energized and the time lag occurring before the knob is retracted is sufficient to ensure that the impeller has stopped rotating when the lid is actually released.

Title: Improvements in or relating to secondary radar
Inventor: BATTY NEVILLE GEORGE
IPC: G01S13/78
Filed: 1961-09-21
Abstract: 959,217. Pulse radar. A. C. COSSOR Ltd. Dec. 19, 1962 [Sept. 21, 1961], No. 33922/61. Heading H4D. Relates to a secondary radar system of the kind in which a target station in response to an interrogating signal transmitted thereto in a rotating beam, transmits a reply in the form of a signal having a " start " pulse, followed by a sequence of pulses in a code carrying information such as target station identity, height, heading and speed, and an " end " pulse, the start and end pulses being referred to as " frame pulses " and always having the same time separation T. In general, the number of responses in a given period will be large and thereby necessitate a data transmission link of wide bandwidth, e.g. exceeding 100 kc/s.; to avoid this, the present invention comprises (a) a first limiter 11, fed with the reply signals and giving a first predetermined pulse amplitude; (b) a circulating pulse store 20 to 25, fed from the first limiter, which store affords a circulation delay equal to the repetition period of the interrogating signals, adds each reply signal to those already stored and attenuates circulating pulses by a predetermined factor on each circulation; (c) means 45, 48, responsive to a circulating pulse, the amplitude of which has risen to a second predetermined value, for adding a " labelling " signal (applied to terminal 51), representing the bearing at which the beam begins to sweep over the target, to the resultant recirculating reply signal in the store; (d) means 24, limiting the amplitude of pulses circulating in the store to a third predetermined value; and (e) means 47, responsive to a circulating pulse, the amplitude of which has fallen from the third to a fourth predetermined value, giving a signal representing the bearing at which the beam ended its sweep over the target. Delay line 12 and AND gate 15 pass only frame pulses of correct spacing. A second store 2 is provided for a second target station. Gate 39, delay circuit 40 and multivibrator 41 are included to prevent maloperation if two targets each transmit reply signals so delayed with respect to each other that a frame pulse from one reply signal is delayed with respect to a frame pulse from the other reply signal by the interval T. The bearing " labelling " signal is in binary code form. A special identity pulse may follow the last frame pulse of a reply signal and if such pulse is spaced from a preceding pulse by the interval T the transfer of information to the store is adversely affected; gate 58, delay circuit 60 and a pulse generator 61 are therefore provided. Gates 33, 64 may incorporate a differential amplifier, Fig. 2 (not shown), or may comprise AND and NOT gates, Fig. 3 (not shown).
