Title: Improvements in or relating to control arrangements for interrelating engine speed control and operation of change speed gearing
IPC: B60W10/10
Filed: 1964-01-15
Abstract: 1,049,924. Change Speed and clutch control. REGIE NATIONALE DES USINES RENAULT. Jan. 15, 1964 [Jan. 30, 1963], No. 1876/64. Headings F2D and F2L. In a combined clutch, gear shift and throttle control for a motor vehicle wherein initial shift movement effected manually or by an output speed responsive control 27 changes a double switch 30, 31 to disengage an electromagnetically operated main clutch 8, 9 and to energize a throttle closing solenoid 47, the throttle 6 is reopened during down-shift when the following three conditions are fulfilled: (1) a ratio establishing clutch sleeve 20 is applied against a friction synchronizing ring 17 with a predetermined force, (2) the main clutch driven element 9 overruns the driving element 8 and (3) the throttle pedal 38 is depressed. The ratio shift control 27 operates a rod 26 which acts through a spring centred lost motion coupling 25 on a shift fork 21 so that when the rod 26 has completed its movement and closed a switch 28 the shift fork 21 and clutch sleeve 20 are biased towards the new ratio position by a predetermined force. The throttle 6 is reopened by energizing a solenoid 33 through a switch 34 closed when the accelerator pedal 38 is depressed, the switch 28 and a switch 37, 41 closed when the clutch driven element 9 overruns the driving element 8. The solenoid 33 opens a switch 36 to de-energize the throttle closing solenoid 47. Establishiment of a new ratio changes the switches 30, 31 to re-engage the clutch 8, 9 and de-energize the throttle control solenoid 47. During re-acceleration the clutch 8, 9 may be partially engaged by supplying a reduced current to its winding 7 through a resistor 50 and a switch 49 operated conjointly with the switch 28. The throttle valve 6 is independent of the main pedal controlled throttle valve 4 and only partially closes the duct 3. In Fig. 3 (not shown) the above device is applied to the clutch control circuit described in Specification 1,028,964.
Patent GB-979399-A (GB)
Title: Bis-(polychlorovinyl) sulphides
Filed: 1963-01-16
Abstract: The invention comprises bis-(polychlorovinyl) sulphides of the general formula <FORM:0979399/C1/1> wherein at least 4 X's are chlorine atoms and the remainder are hydrogen atoms or dichloromethyl or trichloromethyl radicals. The compounds are prepared by the reaction of sulphur dichloride or the appropriate polychloroalkyl-or polychlorovinyl-sulphenyl chlorides with polychloroolefines, which contain at least two chlorine atoms and at least one hydrogen at the double bond, in the presence of a Friedel-Crafts catalyst to give the bis (polychloroalkyl)- or polychloroalkyl-polychlorovinyl-sulphides which are subsequently dehydrohalogenated.  The addition of sulphur dichloride to the chlorinated olefines is preferably carried out using AlCl3, e.g. 0.05 moles based on SCl2, as the catalyst; the preferred reactant ratio is 2 moles olefine to 1 mole SCl2 and suitable temperatures lie in the range 0-40 DEG C.  The reaction using sulphenyl chlorides may be effected under similar conditions using 1 mole appropriate sulphenyl chloride per mole chloroolefine; this latter reaction permits the preparation of asymmetrical compounds of the above formula, e.g., 1, 2, 2, 2-tetrachloro-11, 21, 21-trichloro-ethyl sulphide, 1,2,2,21, 21, 21-hexachlorodiethyl sulphide. Suitable polychloroolefine starting materials are, e.g. 1,1- or 1,2-dichloroethylene, trichloroethylene, 1,2,3,3- or 1,1,3,3-tetrachloropropyl-1-ene or 1, 2, 3, 3, 3-pentachloropropylene. Hydrogen chloride is eliminated from the bis (polychloroalkyl)- or polychloroalkyl-polychlorovinyl-sulphides with the aid of known reagents, e.g., metal oxides, hydroxides or alcoholates or salts of weak acids, e.g., carbonates or acetates, or ammonia or amines. Dehydrohalogenation may be carried out at room temperatures or above.  The compounds of the invention are used as nematocides (see Division A5).  Examples describe the preparation of bis (1, 2-dichlorovinyl) sulphide and bis-(1, 2, 2-trichlorovinyl) sulphide.  Specification 954,440 is referred to.ALSO:Nematocidal compositions comprise bis-(polychlorovinyl) sulphides of the general formula <FORM:0979399/A5-A6/1> wherein at least 4 X's are chlorine and the remainder are hydrogen atoms or dichloromethyl or trichloromethyl radicals, and a solid or liquid diluent or carrier.

Title: Improvements in and relating to the moulding of bricks
Inventor: BIRCH FRED PARKER
IPC: B28B17/00
Filed: 1955-01-22
Abstract: 795,668. Brick-moulding machines. NUNEATON ENGINEERING CO., Ltd. Jan. 16. 1956 [Jan. 22, 1955], No. 1991/55. Class 87(2). [Also in Group XXXV] In a press of the kind in which material fed by an oscillating, cam-operated feed shoe 21 is pressed in a mould cavity 24 by a cam-operated plunger 33 and the moulded brick is ejected by a plunger 25 the position of which may be adjusted by a screw 32 to vary the amount of material to be moulded, a device is provided either to indicate a variation in moulding pressure to allow the position of the plunger 25 to be adjusted to compensate for such a variation or to operate a motor 54 to adjust the screw 32 automatically on such a variation. As shown, a lever 44 pivotally mounted on the frame at 45 is moved during pressing because of the stressing of the frame. If the moulding pressure is too high, a finger 48 operates a micro-switch 50 which causes the motor 54 to raise the plunger 25. Whereas if the pressure is too low, a finger 49 operates a switch 51 to lower the plunger. To prevent the switch 51 from operating when the machine is at rest, a switch 56 is provided in the circuit which is closed by a cam 60 only as the maximum pressure is applied. A further switch 61 is provided to prevent the plunger 25 from being lowered if the supply of material is stopped.

Title: Improvements in and relating to the preparation of penicillin salts
IPC: C07D499/14
Filed: 1948-01-23
Abstract: Ammonium penicillin is precipitated from a solution of penicillin in a non-polar organic solvent by addition thereto of concentrated aqueous ammonia, or, if the penicillin solution contains a proportion of water (not in excess of that required to saturate the solution), by passing in ammonia gas; the precipitate is separated and treated with acetone when substantially pure ammonium penicillin is left in the solid form.  The starting material may be (1) the solution obtained by extracting the acidified culture medium with butyl acetate, treating with water and sodium hydroxide at pH 7, acidifying the aqueous solution and reextracting with ether; (2) the result of extracting with ether an acidified aqueous solution of a partially-purified penicillin salt; or (3) solutions of the various penicillins such as G, X and F alone or mixed in any proportion. Chloroform is also mentioned as a suitable non-polar solvent.  The addition of ammonia is preferably continued until the supernatant liquor is slightly on the acid side of neutrality, e.g. pH 6.5-6.7. The final treatment with acetone is preferably carried out at or near room temperature.  Examples are given of the process of the invention using ammonia gas and the aqueous solution, and the conversion of the product into the sodium salt.  Specification 578,590 is referred to. According to the Provisional Specification, the acetone may contain water or may be replaced by any neutral water-miscible or partially water-miscible organic solvent or a mixture thereof with water, aqueous butanol being specified.
