Title: Improvements in or relating to the production of crude 4,4-dichlorodiphenyltrichloroethane
IPC: C07C25/20
Filed: 1945-10-10
Abstract: In the manufacture of crude 4 : 41-dichlorodiphenyl-trichloroethane, the product is obtained in a dry, divided condition by feeding molten, crude 4 : 41-dichloro-diphenyl-trichloroethane on to a flaking-surface, e.g. a horizontal, hollow, rotating drum, maintained at 40 DEG  to 80 DEG  C., and removing the solidified material. In examples: (1) a hollow, steel drum maintained at 63 DEG  C. by internal circulation of hot water, has its lower portion immersed in a steel trough containing crude, molten 4 : 41-dichlorodi-phenyl-trichloroethane, of which 70 per cent consists of the pure substance and is rotated so as to complete one revolution in 34 seconds thereby allowing sufficient time for the film of material which is collected by the drum to solidify before being removed in a dry, divided condition by a scraper knife disposed at an angle of 240 degrees from the line where the drum leaves the trough; (2) as in (1), the temperature and time of rotation of the drum being changed to 65 DEG  C. and 49.5 seconds respectively.

Title: Preparation of vinyl stearate
Filed: 1957-08-21
Abstract: Vinyl stearate is extracted from a mixture comprising vinyl stearate and stearic acid by means of a paraffin hydrocarbon containing 7 or less carbon atoms, preferably below 15 DEG C., more preferably between about 0 and 5 DEG C.  The vinyl stearate may be further purified by distillation and or treatment with calcium hydroxide or advantageously by treatment with a series of adsorbents comprising magnesium oxide, magnesium silicate and activated carbon, the stearate being preferably passed through the adsorbents.  The vinyl stearate/stearic acid mixture is particularly that derived from a vinyl ester interchange reaction between stearic acid and a vinyl ester such as vinyl acetate in the presence of an interchange catalyst, particularly a mercury compound, e.g. a mercury salt strong acid, e.g. H2SO4, catalyst, which may also be present in the mixture extracted.  The acid byproduct of the interchange is preferably removed before the extraction, e.g. by entrainment during the interchange reaction.  The reaction mixture may also be neutralised, preferably with calcium hydroxide, although sodium acetate, magnesium silicate, magnesium oxide and calcium acetate are also mentioned, any precipitate removed, and volatiles also removed before the extraction.  The stearic acid used to prepare the vinyl stearate may contain up to about 30% palmitic acid. Specifications 869,828 and 869,829 are referred to.

Abstract: 955,982. Toy guns. LOUIS MARX & CO. Ltd. July 29, 1960 [April 15, 1960 No. 26577/60. Heading A6S. A toy gun simulates used shell ejection from the breech portion of the gun, the gun having a magazine for receiving a quantity of shells, a shell ejector at the breech portion of the gun for ejecting a shell transversely of its length, a spring in the magazine urging the shells to the ejector and means to operate the ejector to eject a shell, the spring serving to feed the next shell from the magazine to the ejector after retraction of the ejector. The magazine 40 in the barrel of the gun houses the shells 48, 50 which are urged rearwardly by a spring acting on a pusher 46. The shells are introduced into the magazine through an inwardly pivoting spring-urged door in the breech. The end shell abuts a ledge 56 on a slide 60 carrying an arm 78 with a pivoting ejector 42. Cooking the lever 24 moves the slide 60 rearwardly by a stud 66 on the lever engaged in a notch 64 in the slide and allows the end shell to move to an opening. The trunnions 80 of the ejector 42 move in guides 90 until a finger 84 on the ejector strikes an abutment 86 which rotates the ejector to eject a shell from the breech. Pressing a fingertab 18 forwards a feed dog 144 for the caps which move over a slotted plate to an integral anvil. The finger tab 18 has a lever arm with a stud which engages in a slot 162 in the feed dog. The feed dog has two pins 146 which pass through the slotted plate and grip the caps. The finger tab carries a lateral hammer 128 for striking caps on the anvil. The feed-dog 144 carries a stud 168 which moves over a guide 170 during forward movement, drops at the end of the guide to release the pins 146 from the caps, passes under the guide, is raised at the end by a spring 172 to again abut the top of the guide 170 with the pins 146 engaged in and ready to feed the caps. Pressing the finger tab 18 stretches a spring 152 connecting the hammer end to the gun and pulling the trigger 20 releases the hammer 128 to explode a cap. The end of the branch 122 of the trigger engages the cammed end of the arm 156 of the hammer and when the trigger is pulled the arm 156 is released and the hammer strikes the cap on the anvil. The cocking lever 24 which is provided with a camming edge 182 co-operates with a cam follower 158 on the live arm 156 to cock the hammer lever which is locked by the branch 122 of the trigger 20 until the trigger 20 is pulled, this results in a cap being exploded and a shell being ejected. The outer body of the gun is moulded from plastics material in two halves aligned by dowels engaging in holes and cemented together and with sockets for studs on the frame member 200. Specification 955,983 is referred to.

Abstract: 1301154 Pulse-width modulated inverters B S RUDERT 3 June 1970 [9 June 1969] 26815/70 Heading H2F In an inverter comprising a pair of thyristors T1, T2 each arranged to commutate the other, trigger signals A, B (Fig. 2) are applied to the respective gates, comprising short pulses 3 of duration less than the turn-off time of a, thyristor and capable of turning off both thyristors in succession followed by a longer pulse 4 of duration greater than the turn-off time of a thyristor, the effective value of the output being determined by varying the duration of the long pulses 4. As described, when thyristor T1 is turned on by a short pulse 3, T2 is turned off by action of the commutating capacitor C1; L2 and C1 ringing so as to turn off T1 after the termination of pulse 3. T1 is then turned on by pulse 4 and remains conductive until a pulse 3 is applied to T2. C1 and L4 are arranged to resonate at two or three times the operating frequency. C2 and L4 normally resonate at the operating frequency, but in the event of excessive load current, double Zener diode M breaks down so as to limit the load current. Diodes D1, D2, D3 return reactive energy to the supply B. The inverter may be finally turned off by application of a single pulse 3 to the conducting thyristor. Fig. 3 (not shown), depicts a block diagram of a control pulse generator comprising an oscillator feeding a pulse modulator arranged to determine the duration of the wide pulses 4 in response to the load voltage.
