Title: New cyclopentano-naphthalene derivatives and processes for their production and use
IPC: C07C69/013
Filed: 1961-05-18
Abstract: The invention comprises cyclopentanonaphthalene derivatives of formula <FORM:0928317/IV(a)/1> where -OAc is acyloxy; either X and Y together constitute a double bond and Z is -NR1R2 (R1, R2 are C1-6 alkyl or -NR1R2 is an N or N + O heterocyclic residue), or X is g -chloro-2-butenyl while Y and Z constitute together the oxygen atom of a keto group.  The heterocyclic residue may be for example piperidinyl, morpholinyl or pyrrolidinyl.  Ac is preferably benzoyl, but may be also, e.g., acetyl, trimethylacetyl, phenoxyacetyl, propionyl, b -cyclopentylpropionyl, phenylpropionyl, 4,4-dimethylpentar???yl, 10-undecanoyl, hexahydroterephthaloyl or hexahydrobenzoyl.  The enamines of the invention are prepared by reacting a compound of the above formula, but in which the double bond is in the position common to the 6-membered rings, X is H and YZ is O=, with a secondary amine HNR1R2 in an inert organic solvent. The chlorobutenyl??? compounds of the invention are prepared by reacting an enamine of the invention with the compound X1CH2CH = CCl.CH3 (X1 = halogen); the latter, where X1 = I, is made by reacting an alkali metal iodide (e.g. NaI) with 1,3-dichloro-2-butene in a polar medium such as dimethylformamide.  The chlorobutenyl compounds of the invention may be hydrolysed to give products which are of the above general formula, but in which the double bond is now in the 8-position instead of the 9, X is acetonylmethyl and YZ is O=. Specifications 914,732 and 914,735 are referred to.

As shown device 1 is for fitting in the windowscreen of a car when the car is parked in a restricted area. It is switched on and switch 3 set to one of zones 3a, 3b or 3c. These zones correspond to different rates of count down frequency and correspond to different parking areas. Counters 2b, 2c and 2d show the count down. A disc 2a has different colours one of which is shown at a time. Normally a green colour is shown. When the counters reach zero, a red colour is shown. Device 1 can fit into recess 24 in device 20 and engage pins 25. There are detection means for ensuring that the storage device 1 is correct for the device 20. An operator of the device 20 operates it to transmit pulses to device 1 to operate the counting mechanism therein so that the time purchased is recorded. If a buyer purchases 999 units and say 020 is still shown on device 1, then on feeding the time into device 1 disc 2a shows white and the counters show 020. This denotes to a parking warden that when the counters reach 000 the parker is not committing an offence. Instead the counters will move on to 999 and disc 2a will show green.

Abstract: 110,990. Frazer, J. K. Dec. 30, 1916. Skips.-In a skip A for carrying coal, coke, &c., the bottom doors are locked and unlocked by mechanism located within a housing B and actuated by tensioning the rope 10 or depressing the rod 17. Each door 12 is hinged to a side of the skip, and prevented from opening too far by a chain 1 and/or stops 2. The doors are engaged by two opposed pairs of pivoted dogs 3, each pair of which is connected by toggle links 4 and links 5, 6 to a rock-shaft 26. An arm 7 fixed to the shaft 26 is connected by a rod 8 to a lever 9 pivoted at one end in the upper edge of the skip, weighted at the other end 11, and secured to the rope 10. When the rope 10 is tensioned, the dogs 3 are withdrawn, and the doors fall. If the skip is lowered so that the doors bear on joists, &c., the doors will swing upwards and be locked autornatically, but if it is desired to close them from overhead the rod 17 is depressed and the doors raised by the consequent upward movement of the ropes 16. A rack on the rod 17 engages pinions 14 secured to pulleys 15 around which the ropes 16 pass. The upward movement of the rod 17 which occurs when the doors open is cushioned by a spring 18. In a modification, the doors are closed by the upward movement of ropes which pass over pulleys on the top of the skip and are secured to a cross-head moved vertically by a rod similar to the rod 17. Means also are provided on an extension of the cross-head for bringing the dogs 3 to unlatching position for the doors to close, and for permitting the retraction of the dogs by the weight 11.

Title: Improvements in the production of bituminous emulsions
IPC: C08L95/00
Filed: 1935-07-02
Abstract: Aqueous dispersions of bituminous and like materials are obtained by dispersing such materials in a hot dilute solution of a fixed alkali, using fatty acid pitch, e.g. stearine pitch, and a protein compound as assistant emulsifying agents, the quantity of water in which the bituminous materials are first dispersed and the proportion of protein compound being sufficient to prevent reversal of the phases. The bituminous materials are defined as pyrogenous residues of organic substances and include pitches, tars, artificial or natural bitumens or viscous hydrocarbons. Hard and soft pitches may be combined or mixed with a suitable flux.  The protein material includes casein, glues, gelatine or albumens and is preferably added as alkali caseinate solution which may be neutralized, e.g. with tannic or boric acid and protected from decomposition.  Suitable alkalis include alkaline salts of organic or inorganic acids, esters or gels which are readily hydrolyzed.  The fatty acid pitch may be mixed with the bituminous material at 105--110 DEG  C. and then stirred into part of the alkali solution, e.g. at 90--100 DEG  C. followed by the solution of casein and sufficient water to give a 50 per cent emulsion. Alternatively, the bituminous material and fatty acid pitch may be added to the whole of the aqueous phase, or part of the fatty acid pitch may be added to the aqueous phase.  According to an example, 180 pts. of coal tar pitch and 20 pts. of stearine pitch at 105--110 DEG  C. are stirred into 45 pts. of casein solution (formed from 56 pts. casein, 10 pts. caustic potash, 50 per cent solution, 494 pts. water and 11 pts. cresylic acid) and 35 pts. water containing 1 pt. caustic potash at 100 DEG  C., followed by the addition of 120 pts. of water.  Specifications 255,074 and 308,051, [both in Class 81 (i)], are referred to.

Title: A hand operated machine for making precast blocks or bricks
IPC: B28B13/06
Filed: 1949-07-19
Abstract: 653,958. Moulding concrete blocks &c. STURTEVANT, R. L., STURTEVANT, B. J., and STURTEVANT, jun., R. L. July 19, 1949, No. 18921. [Class 87 (ii)] In a hand-operated machine for making blocks or bricks of concrete &c. the compression of the loose material within the mould box and the ejection of the finished article are effected in predetermined order by unidirectional movement of a hand lever. A wooden pallet 26 is positioned in'the mould box, the box charged from a hopper 38 and the charge levelled off by closing by hand the pivotal top cover 18. The operator then pulls lever 9 from the vertical position, Fig. 2, to the depressed position, Fig. 6, thus rotating the shaft 6 and cams 10, 11, 11. During this movement, (1) bars 15, 16 connected respectively to mould sides 12, 13 and engaging cams 11, 11 through rollers 17, are moved in opposite directions against the tension of a spring 14, thus causing the mould sides 12, 13 to move towards each other and compress the material in the mould ; (2) engagement of the rollers 17 on the bars 16 with low portions 11a on the cams 11 causes the mould side 13 to move back slightly and thus relieve the pressure ; (3) the peripheral portion 10a of the cam 10 contacts roller 21 of bars 23 and knocks back cover-plate 18 ; at the same time the side plates 12, 13 become free to open fully under the influence of the spring 14 ; (4) the cam 10 displaces roller 36, thus tilting bars 35, 28 and raising mould bottom 25 on its pillar 27. During ejection a peripheral extension 10b on the cam 10 bears against the roller 21 and prevents accidental closing of the cover 18.
