Abstract: 903,541. Control of wagon haulage apparatus. NORTONS-TIVIDALE Ltd. Jan. 9, 1961 [Oct. 8, 1959], No. 30650/59. Class 105. In wagon haulage apparatus of the type described in Specification 815,432, in which a remote-controlled rope-operated haulage bogie running on a narrow gauge track 3 between the wagon rails is provided with retractable arms, terminated with rollers 7, 8, which can be extended to engage the wheels and associated axle of a selected wagon, the bogie is provided with magnetic proximity devices 9, 10 which detect the presence of a wagon wheel flange and indicate to an operator, via a circuit which extends'over the bogie rails 3, the correct position for extending the arms to engage a wagon. The detectors each comprise two coils (9 only shown) and form with pick-up shoes 14, rails 3 and condenser 30, one arm of an A.C. bridge circuit which includes resistors R1, R2 and R3. The change of impedance as the detectors pass a first flange produces a signal which is amplified, 31, and switches a bi-stable circuit 33 to its first state in which a signal appears on lead 35. This is amplified, 37, and operates a relay 38 to a position in which a green lamp 17 is illuminated. The next flange produces a signal which resets the bi-stable circuit and a red lamp 18 is illuminated. Specification 688,467 also is referred to.

Abstract: 761,320. Angular bending. VEB SCHWERMASCHINENBAU H. RAU. Oct. 27, 1954, No. 31017/54. Class 83 (4). [Also in Group XL (b)] A process for bending flat or profiled metal plate in which the plate is passed between rollers which extend one side more than the other, the more extended side forming the outer part of the bend, and which are adjustable to vary the pressure on the plate is characterized in that the pressure of the rolls is controlled during bending by means co-operating with a curved guide which the leading end of the plate being bent follows. A flanged plate 1, to be bent to form a ship rib, is fed between a driven roller 3 and a roller 2 carried by a plate 4 adjustable vertically by the rotation of eccentrics 5 and 6. The initial adjustment is effected by a hand wheel 7, turning eccentrics 5, 6. The hand wheel 7 is then uncoupled and a worm wheel 9, adapted to be rotated by a motor 12, coupled tothe eccentric 5 and the rolling is commenced. The leading end of the plate being bent follows a curved guide 13 and carries means which co-operate with the guide 13 so that as the end tends to deviate therefrom the roll pressure is increased or reduced accordingly to effect correction by causing the motor 12 to rotate the eccentric 5 one way or the other. The means may comprise a lever coupled to the motor, or as shown, a photo-electric cell 10, the output of which actuates the motor 12, in which latter case the guide 13 comprises a white wire on a black plate.

Abstract: 1516835 Bookbinding machines PLESSEY CO Ltd 11 July 1975 [13 July 1974] 31120/74 Heading B6A [Also in Division B8] A bookbinding machine includes a first pusher head 7 movable to position one edge of a cheque or like book 31 at a first location, and a second head 11 movable to position the opposite edges at a second location, for bookbinding operations to be effected. Each head 7, 11 is coupled to linkages which bias the heads together. A common, pneumatically actuated bar 14 has projections 18, 19 which engage the linkages. Initially the bar is moved leftwards, head 7 abuts stop 20 at the first location 21, and a pneumatic motor 27 draws head 11 leftwards. A conveyer then moves a stapled book 31 between the heads, and head 11 is released to clamp it. Adhesive tape 32 is pressed on to the one edge of the book by a roller 37 and the bar 14 is moved rightwards causing the head 11 to push the book past the roller 37, to press the tape along the book end. The head 11 then engages a second stop defining the second location which coincides with the first. The tape is cut by rollers 37, 39, the head 7 is moved against spring 12 and the book is removed. The tape is unwound from a spool by a vacuum clamp 40. In a second embodiment the heads define different locations on either side of a stapling head.

Abstract: a -Chloroglutaric acid is prepared by treating 1,1,1,5-tetrachloropentene with a Friedel-Crafts catalyst under anhydrous conditions and elevated temperature, hydrolysing the resulting 1,1,5-trichloropentene-1 by heating in aqueous alkaline solution, chlorinating the resulting 1,1 -dichloro-5-hydroxypentene-1 by mixing with an acidic compound and passing chlorine through the mixture, and pouring the reaction mass into water and finally oxidizing the a  - chloro - 5 -hydroxy - valeric acid by con tacting with an oxidizing agent under non-alkaline conditions in the substantial absence of water.  The acid used in the chlorination step may be sulphuric, formic, acetic or phosphoric acid.  The oxidizing agent may be a perman ganate, a bichromate, anhydrous chromic acid, nitric acid or nitrogen peroxide, and the oxidizing medium may be chloroform or carbon tetrachloride.  An alternative method of hy drolysing 1,1,5-trichloropentene-1 is to heat it with an alkali metal salt of an aliphatic carb oxylic acid in a carboxylic acid solution and then hydrolyse the resulting ester.

When a bobbin feeler (not shown) indicates need of replenishment a feeler 15 is advanced by a lever 10 to initiate replenishment if the shuttle 1 is correctly positioned and if, in fact, replenishment is necessary. If the feeler 15 penetrates sufficiently far into the shuttle 1 the sley 5 pivots a lever 13 so that it abuts a slide 8 causing it to actuate the hammer 6 to insert the new bobbin 4 which, as it enters the shuttle, deflects the feeler 15 which cuts and grips the old weft end. A member 23 may, alternatively, deflect the feeler. If the feeler 15 does not enter sufficiently into the shuttle, due either to mislocation of the shuttle or to too much weft remaining on the bobbin, the feeler 15 is pushed back so that the sley 5 does not pivot the lever 13 (Fig. 3.)

Abstract: Heterocyclic compounds of the general formula <FORM:0617709/IV(b)/1> where R1 is a phenyl or substituted phenyl radical R1 is hydrogen or an alkoxy radical, R3 is hydrogen or an alkyl radical and <FORM:0617709/IV(b)/2> denotes the residue of a heterocyclic compound containing a cyclic secondary nitrogen atom, are prepared by treating an aroyl acid chloride R1COCl with the appropriate hydroxy-a -haloketone to give the ester <FORM:0617709/IV(b)/3> where Z is a halogen atom, and treating this with a heterocyclic amine to obtain the required product.  Preferably an esterified hydroxy-a -chloroketone is treated with two equivalents of the heterocyclic amine.  Alternatively the compounds may also be obtained by treating a hydroxy-a -haloketone first with the amine and then with the aroyl acid chloride.  Preferably a hydroxy-a -chloroketone is treated with three or more equivalents of the heterocyclic amine in the presence of a small amount of potassium iodide.  The bases are normally employed as their hydrochlorides or other acid salts.  In examples: (1) 4-benzoxy-o -chloroacetophenone is treated with piperidine to give N-(p-benzoxy-phenacyl) piperidine; (2) 3-methoxy-4-hydroxy-o -chloroacetophenone is treated with piperidine and the product is benzoylated to give N-[(3-methoxy-4-benzoxy) phenacyl] piperidine which is isolated as the hydrochloride; (3) 3-methoxy - 4 - hydroxy - o  - chloroacetophenone is treated with benzoyl chloride and the product is reacted with piperidine to give the product of (2); (4) 3-methoxy-4-hydroxy-o -chloroacetophenone reacts with anisoyl chloride followed by piperidine to give N-[3-methoxy-4-anisoxy)-phenacyl] piperidine hydrochloride; (5) 3-methoxy-4-benzoxy-o -chloroacetophenone reacts with tetrahydroquinoline to give N-[(3-methoxy - 4 - benzoxy)phenacetyl]tetrahydroquinoline; (6) by using morpholine in place of tetrahydroquinoline in the process of (5) N-[(3 - methoxy - 4 - benzoxy)phenacetyl)]tetra-hydroquinoline is obtained.
