Title: Novel compositions for suppressing growth of neoplasms
IPC: A61K31/655
Filed: 1963-01-25
Abstract: Substituted tetrazenes having the formula <FORM:0978367/C1/1> wherein R is phenyl or p-nitrophenyl and R1 is methyl or ethyl, are prepared by oxidising a substituted hydrazine having the formula <FORM:0978367/C1/2> wherein R and R1 have the meanings given above. The reaction is conveniently carried out in an inert solvent such as benzene, toluene, xylene or chloroform under reflux (50 DEG  to 120 DEG C.). Mercuric oxide is a suitable oxidising agent. An example illustrates the preparation of 1,4-dimethyl-1, 4-di-(p-nitrophenyl)-2-tetrazene from N-methyl -N-p-nitrophenylhydrazine, N-methyl-p-nitroaniline being formed as a by-product. The substituted tetrazenes are used in pharmaceutical compositions (see Division A5).ALSO:Compositions in dosage unit form for suppressing growth of neoplasms comprise as the active ingredient 1 to 250 mg. of a compound of the formula <FORM:0978367/A5-A6/1> wherein R is phenyl or p-nitrophenyl and R1 is methyl or ethyl, and a pharmaceutically acceptable carrier therefor.  Active ingredients specified are 1,4-dimethyl-1,4-diphenyl-2-tetrazene, 1,4-diethyl-1,4-diphenyl-2-tetrazene and 1,4 - dimethyl - 1,4 - di(4 - nitrophenyl) - 2 - tetrazene.  Suitable carriers include propylen, glycol, polyethylene glycol, ethyl lactate, ethyl succinate, dimethyl sulfoxide, hexamethyl phosphoramide, sesame oil, peanut oil, ethanol and starch.  The compositions may be used in the form of tablets, capsules, pills, powders or suspensions.

[Classes 7 (i) and 7 (ii)] In a power unit consisting of at least one installation for supplying power gas, and at least -one secondary engine employing such power gas, the installation for supplying power gas comprises a two-shaft opposed-piston two-stroke Diesel engine and reciprocating compressors in which the forces produced by the rotary parts both of the Diesel engine and of the compressors are balanced, and in which the pistons of the Diesel engine and of the compressors are arranged in pairs, the two pistons in each pair moving in phase but in opposite directions, while the two crankshafts have equal rotary momentum, but rotate in opposite directions. Alternatively, rotary compressors may be employed, the sum of the products of angular velocity and the moments of inertia of all the main rotating parts being zero. As shown, the Diesel engine has parallel cylinders with opposed pistons, 2, 2<1> connected to crankshafts 4, 5 synchronized by means of gearing 11, 12, 12<1>, 13. The bearings for the crankshafts may be tied together by tie bolts 38, 39. Piston-controlled inlet ports 18, 19 and exhaust ports 23, 24 are uncovered by the pistons 2<1>, 2 respectively at the end of their outstroke, the inlet ports being connected by pipes 20, 21 to the delivery side of the compressors, which are double-acting, with valvecontrolled inlet and delivery ports 37, 33. The pressure of the power gas at full load is at least four atmospheres and the compression pressure in the combustion chamber does not exceed 120 atmospheres. Starting and running on low load is facilitated by means such as throttling means for the exhaust, sparking plugs, or throttling and pre-heating means for the air drawn into the combustion chamber.

Title: Improvements in an engine starter and generator gearing
IPC: F02N99/00
Filed: 1930-02-04
Abstract: 354,687. Epicyclic variablespeed gearing. FORD MOTOR CO., Ltd., 93, Regent Street, London. Feb. 4, 1930, No. 3800. Convention date, Feb. 4, 1929. Void [Published under Sect. 91 of the Acts]. [Class 80 (ii).] An electric starting motor drives the engine shaft at starting through planetary gearing and is afterwards driven as a generator at engine speed, the gearing then rotating as a unit. In one form, Figs. 1, 2, and 3, the hubll of an internal gear 13 is mounted on the engine shaft 10, and a fan belt pulley 17 is bolted to the gear 13, the remainder of the gearing being enclosed within the pulley and the gear 13. A planet gear 37 meshing with the gear 13 is rotatable on roller bearings 36 upon an eccentric 28 on the end of a sleeve 27 connected directly to the armature of the starting motor and rotating in roller bearings 34 in a stationary sleeve 31. When driven from the starting motor, the planet gear 37 oscillates upon the eccentric 28 without rotation and effects a slow rotation of the internal gear 13. The means for restraining the planet gear from rotation comprises ratchet teeth 35 formed on the exterior of the sleeve 31 and engaged by pawls 38 pivoted on pins 39 secured at each end in rings 26, 40 rotatable within the pulley 17. A pair of driving pins 42 extending rearwardly from the ring 40 are provided with rollers 43 engaging radial slots 47 in a ring 46 within the sleeve portion 18 of the pulley 17. A second pair of radial slots 47 in the ring 46 are engaged by rollers 45 on pins 44 integral with the planet gear 37. When the sleeve 27 is driven by the starting motor, rotation of the ring 46 and the planet gear 37 is prevented by the pawls 38, and the internal gear 31 is driven at reduced speed, oscillation of the ring 46 being allowed by the slots 47. When the engine shaft 10 is the driver, the sleeve 27 is driven from the shaft 10 through a free-wheel clutch 30 on the part 24 of a manual starting shaft 21, which is permanently secured at 23 in the forward end of the engine shaft; and the gearing rotates as a unit, the pawls 38 being disengaged from the ratchet 35 by centrifugal action. In a modification, Fig. 5, the gearing is enclosed within the casing of the starting motor. A shaft 54, which can be manually actuated, is connected to the engine shaft 10 by a splined sleeve 55, and the internal gear 13 mounted on the shaft 54 is extended forwards to enclose the pawl mechanism 38 &c., the ratchet 35 of which is secured to a sleeve 61 on the cover 52. A freewheel roller clutch is provided between the rings carrying the pawls 38 and the extension 59 of the gear 13. The bell-shaped armature 65 has a sleeve 66 secured to the forward end of the sleeve 64.

Abstract: 641,384. Punching-machines. SLOPER & CO., Ltd., J., and FIRMINGER, R. T. Feb. 10, 1948, No. 3832. [Class 31 (ii)] A power-driven machine for perforating strip material with figures &c. comprises a set of keys and key-levers similar to those of a typewriter, with one key and lever for each symbol, each lever carrying at its end a perforated plate for action in conjunction with a perforating device having a number of pins which cover the whole area of the largest symbol and each plate being perforated so that unwanted pins can pass through the perforations, the arrangement being such that on striking a key the appropriate plate is moved into the perforating device and held there, the power drive is operated to effect perforation and all parts then return to normal. As shown in Fig. 2, a machine comprises a main frame 1, a frame 2 vertically movable in the main frame and carrying keys, not shown, and key-levers 4 similar to those of a typewriter, a main shaft 6 carrying an eccentric 5 adapted to raise and lower the movable frame, a carriage 8 for the material movable across the main frame and urged in one direction by spring means (not shown) and escapement means 30, 31, controlled by the movable frame 2 to allow the carriage to move step-by-step under the action of its spring. Secured to the movable frame is a block 18 having a number of holes therein and a block 19 having a number of coinciding holes each provided with a pin or punch, an anvil 21 having coinciding holes being secured to the main frame and the material 24 passing between the block 19 and the anvil. Upon depression of a key, a clutch 23 is engaged and shaft 6 commences to turn, and a plate 9 attached to the key-lever is swung into position between the blocks 18 and 19 and is held there whilst the frame 2 is raised by eccentric 5; the appropriate punches contact the plate 9 and are forced upwards to perforate the material whilst the unwanted pins pass through holes in the plate 9 and are not operated. When the shaft 6 has completed a single revolution the plate 9 and the clutch 23 both release and the machine returns to normal.
