Title: Improved pigments
IPC: C01B33/113
Filed: 1962-09-06
Abstract: 970,958. Silica coated-barium metaborate pigment. BUCKMAN LABORATORIES Inc. Sept. 6, 1962 [Jan. 24, 1962], No. 34194/62. Addition to 879,499. Heading C1A. A process for producing a silica-coated 'barium metaborate pigment, the coating being amorphous hydrated silica in a proportion between 3 and 20% by weight of the pigment comprising the mixing of barium metaborate particles with a silicon-containing compound selected from amorphous silica, silicic acid, silica gel, colloidal silica suspension, colloidal silica powder and barium silicate, in an aqueous medium, said silicon-containing compound in' an aqueous medium being prepared other than by deionization of an alkali metal silicate solution, the silica comprising from between 3 and 25% by weight of the barium metaborate, heating the mixture at a temperature of at least 75‹ C., and subsequently separating the solid particles from the aqueous medium. The mixture may be heated at a temperature between 75‹ and 200‹ C. for a period not in excess of 8 hours. Barium metaborate may be prepared in situ in the aqueous medium by reaction of barium sulphide and alkali metal tetraborate. Barium hydroxide and other water-soluble barium salts may be used instead of barium sulphide, and boric acid or other water-soluble borates may be used instead of alkali metal tetraborate. When using barium sulphide, a soluble zinc salt may be added to the wet product, after separation but before drying, in order to react with sulphide present thus forming insoluble, inert zinc sulphide. A typical example tabulates quantities of various forms of silica which are refluxed with barium metaborate and water for six hours as well as the percentage loss of product in the filtrate.

Title: A process for the manufacture of unsaturated ketones
IPC: C07C49/203
Filed: 1955-12-02
Abstract: In a process for the manufacture of the unsaturated ketones of the general formula: <FORM:0789411/IV (b)/1> wherein R1 represents an alkyl radical containing from 2 to 5 carbon atoms or the phenyl radical, R2 represents the methyl radical of R1 and R1 together represent the pentamethylene radical, an alcohol of the general formula: <FORM:0789411/IV (b)/2> wherein R1 and R2 have the aforesaid values, is reacted with diketene or an acetoacetic ester and the resulting acetoacetate is subjected to decarboxylation and rearrangement by heating same.  The latter process may be carried out in the presence of a transesterification catalyst, e.g. sodium methylate. Alcohols employed as starting materials include 3-methyl-penten-(1)-ol - 3; 3,5 - dimethyl - hexen - (1) - ol - (3), 3-phenyl - buten - (1) - ol - (3) and 1 - vinylcyclohexanol.  In examples: 6-methyl-octen-(5)-one-(2) is obtained by adding diketene to a mixture of 3-methyl-penten-(1)-ol-(3) petroleum ether, pyridine and acetic acid to form 3-methyl-penten-(1)-yl-(3) acetoacetate which is separated and heated until evolution of carbon dioxide ceases (1); in similar processes 6,8-dimethyl-nonen-(5)-one-(2) is obtained by converting 3,5-dimethyl-hexen-(1)-ol-(3) to the acetoacetate and heating the latter (2); 6-phenyl-hepten-(5)-one-(2) is obtained by converting 3 - phenyl - buten - (1) - ol - (3) to the acetate and heating the latter (3); 5-cyclohexylidene - pentanone - (2) is similarly obtained by converting 1-vinyl-cyclohexanol-(1) to the acetate and heating the latter (4); 6-phenyl - hepten - (5) - one - (2) is also obtained by heating 3-phenyl-buten-(1)-ol-(3) with ethyl acetoacetate when separation of ethyl alcohol and carbon dioxide occur.

Title: Parking equipment
IPC: E04H6/42
Filed: 1973-07-19
Abstract: 1436234 Vehicle barriers NIPPON SIGNAL CO Ltd 19 July 1973 [29 Nov 1972] 34555/73 Heading E2M [Also in Division G4] Parking equipment comprises a ramp 12 over which the leading wheels of a vehicle to be parked pass, the ramp being thereby depressed to energise a spring 23, mechanism operated by the spring to cause the ramp to rise to detain a vehicle when the wheels have passed over it, and means, which may be coinfreed, operable to allow the ramp to return to its original postion and enable the vehicle to leave. An auxiliary ramp 31 is positioned in front of ramp 12 and is connected to the ramp to prevent it being raised unless the vehicle wheels depress the auxiliary ramp before the main ramp. In the embodiment shown the ramp 12 is fixed to a shaft 11 which carries a fixed bellcrank 13 and a relatively rotatable latch plate 14. On depression of ramp 12, Fig. 3, bellcrank engages and rotates plate 14 the spring 23 being compressed between the end of a cylinder 20 moved downwardly by the plate 14 and the head 22 of a rod 21 pulled upwardly through linkage 17, 18 connected to the bellcrank 13. The plate is held in its rotated position by a latch 25 and as the vehicle wheels leave the ramp the spring acts on rod 21 to pivot bellcrank 13 and raise the ramp behind the wheels, the ramp being held raised by a pawl 57 engaging a ratchet 51 on rod 18. At the end of the parking period the insertion of a coin in meter (B) enables the depression of a pedal (60a) to pull rod 61 downwardly, release latch 25 and pawl 57, and enable the ramp to return to its initial position (Figs. 1, 2 and 15, not shown). The ratchet 51 is fixed to the rod 18 by means of a pin 53 which shears when there is an excessive load on the ramp, and prevents damage to the remainder of the mechansim (Figs. 12 to 14, not shown). Auxiliary ramp 31 is connected via a transmission mechanism to means for preventing a full depression of the ramp 12 sufficient for plate 14 to be engaged by latch 25 unless ramp 31 is previously depressed, (Figs. 5 to 11, not shown).

Abstract: 349,005. Rotary electric rectifiers. GOZZANO, A. and SOC. ANON. ACCUMULATORI DR. SCAINI, 340, Viale Monza, Milan, Italy. Nov. 12, 1929, No. 34566. Convention date, Nov. 13, 1928. [Class 38 (ii).] Commutator switching arrangements. - An alternating current rectifier comprises a commutator mounted on the shaft of a synchronized asynchronous motor, the commutator having alternate segments isolated. Single-phase A.C. is supplied through slip rings and D.C. collected from the commutator by a special arrangement of brush gear. The commutator is composed of active segments 5, 7, 9, 11, interspaced by isolated segments 6, 8, 10, 12, the active segments being connected alternately to the rings 13, 14 to which the A.C. supply is connected. The four brushes are connected together in pairs. They are separately adjustable and set so that when brush 15 leaves an active segment connected to (say) ring 14 brush 16 passes on to an active segment connected to ring 13, the reverse operation simultaneously taking place at the brushes 17, 18, so that at any instant one of the brushes of pair 15, 16 is connected to one ring and one of the brushes of the pair 17, 18 is connected to the other ring. As a fresh set of segments come under the brushes a reversal of connections takes place thus giving complete cycle rectification. Fig. 3 (not shown) is a modified arrangement in which the brushes of each pair are placed close together so as to connect with the same segment. The brush positions are adjustable as before. In a further modification of the arrangement shown in Fig. 5, each pair of brushes is replaced by a single brush having a suitable arc length. By adjusting the brush positions it is possible to make the commutator conduct only for voltages over a certain value. When three-phase supply is available a static transformer is used to convert the supply into two-phase and then each phase is rectified and the outputs combined. Reference has been directed by the Comptroller to Specifications 19729/92 and 8412/94, [both in Class 38, Electricity, Regulating &c.].

A space is left between the cones to permit adjustment for wear. The tube fits on a stud 29 which is threaded into a hole 30 in the carriage and is formed with a head 31 abutting on a finished surface 32. The tube 25 and cones are held stationary by means of a screw 33 threaded into the stud. The rollers may have a peripheral groove 18 to prevent contact with the top of the rail 14. The front roller consists of two parts of different diameters, the small part 42 running in a groove 43 in a frame-bar 16, and the large part 41 being mounted on a ball-bearing consisting of balls 39 running in a groove 40 in the roller, and on cones 38 mounted on a tube 48 which is secured by means of a screw 34 to the carriage 11. The tube is formed with a flange at one end, and the other end is expanded. The roller and bearing constitute a detachable unit. The small part 42 permits the employment of a low narrow frame-bar 16 that does not hide the printing line, and the part 41 provides a substantial bearing for the roller.
