Abstract: 1,071,336. Laminates and laminating. DECCA Ltd. Aug. 26, 1964 [Sept. 16, 1963], No. 36413/63. Heading B5N. [Also in Divisions B6 and G5] Gramophone records are labelled by pressing metal foil against the record by means of a heated line block, the record being supported by means permitting movement against a constant restoring force when the applied force exceeds a predetermined value. As shown, a line block 32 containing a heater is replaceably secured to a plate 21 by a bayonet fastening 33 having a handle 34. The plate 21 is slidably mounted on rails 22 and is pressed forward by toggle link mechanism 27, 28, 29 actuated by pneumatic means 26. Records 11, made by moulding blanks and embossing sound tracks therein, are fed in succession upwardly (i.e. normal to the plane of the fig.) by chains projections on the links of which engage the edges of the records, and are held by nylon guides 52 mounted on spring studs 53. A web of aluminium or other metal foil 58 preferably having a plastic backing, is fed in front of the record from a roll 59 on one side of the apparatus and the residue from the block labelling is wound on a similar roll on the other side. The record 11 is positioned by a stud 41 which serves to secure two sheets of nylon 38, constituting a resilient pad, to the head 43 of a hydraulic piston 35. The latter is connected hydraulically through bellows 45 to a chamber 49 containing a nitrogenfilled bag 51 the partial collapse of which, on backward movement of the piston, results in the maintenance on the piston of a hydraulic cushion of substantial constant pressure which is adjustable by adjusting the gas pressure in the bag. The plate 21 carries studs 54 which are opposite the studs 53 and are pressed by stronger springs. In use, with the record and metal foil in position, the plate 21 and line block 32 are moved forward, causing studs 54 to engage studs 53 and press them back against stops, not shown, together with the guides 52 and the record held thereby; further forward movement of the block 33 then presses the foil on to the record against the pad 38, which compensates for variations in thickness of the centre portion of the record, and against the constant hydraulic pressure of the piston 35. After retraction of the block 32 the record is moved upwardly to a similar apparatus reversely mounted for the labelling of its opposite side. The toggle mechanism 27-29 may be replaced by hydraulic pressing means, in which case the nylon pad 38 is used alone, the hydraulic cushioning means being dispensed with.

IPC: C07D501/24
Filed: 1973-08-01
Abstract: A process for the N-deacylation of 7-acylamido-3-hydroxymethylcephalosporins, in which, in a multi-stage process, the 7-amino group is liberated and the hydroxyl group in the 3-hydroxymethyl group is replaced by a halogen atom. First, the starting compound is reacted with an imide-halide-forming reagent in the presence of a base and thereafter the imide-halide formed is reacted with an iminoether-forming compound, after which the iminoether thus obtained is cleaved hydrolytically. The products of the process may be used as starting material or as precursors for the preparation of antibiotically active cephalosporins. To prepare cephaloridine and cefalozine, the product of the process is first N-acylated in an appropriate manner, after which the halogen atom in the 3-halogenomethyl group is replaced by the appropriate radical.

Abstract: 951,480. Exciting alternators. S. BROD. Jan. 18, 1963 [Oct. 23, 1961], No. 37919/61. Heading H2A. [Also in Divisions G3 and H4] The output voltage of a self-excited A.C. generator is regulated by controlling a variable shunt impedance connected across the field winding of the generator. As shown, a generator G having output leads B1, B2 and B3 is self-excited over a current transformer T1 and a rectifier MR1, the field winding F being shunted by a switching transistor Q3 controlled by a multivibrator circuit which includes transistors Q4, Q5. A direct voltage proportional to the output voltage of the generator is derived from a second rectifier MR2, and this direct voltage is compared with a reference voltage, across terminals BV1, RV2, to produce a control voltage which is applied to a transistor Q6 regulating the multivibrator circuit. Variations in the output voltage about a desired level produce corresponding variations in the conductivity of transistor Q6, thus altering the on/off ratio of each output cycle of the multivibrator circuit of Q4, Q5, whereby the period of conduction of transistor Q3 during each cycle of the multivibrator is varied in such a manner as to keep the output voltage constant. In another embodiment (Fig. 1, not shown), the field winding is shunted by a transductor controlled by an error voltage derived from a Wheatstone bridge which includes a Zener diode as a reference source.
