Title: Improvements in or relating to measuring or recording instruments
IPC: G01R13/00
Filed: 1935-03-04
Abstract: 453,191. Electric signalling systems. ELECTROFLO METERS CO., Ltd., Abbey Road, Park Royal, London.-(Republic Flow Meters, Inc. ; 2240, Diversey Parkway, Chicago, U.S.A.) March 4, 1935, No. 30425. Divided out of 453,130. Drawings to Specification. [Class 40 (i)] In an instrument in which a pair of feelers periodically find the position of a clamped pointer, the feelers have extensions which ride in slots in a rotatable disc until one of the feelers passes its central position when its extension engages the end of its slot and carries the disc along until the feeler reaches the clamped pointer. An auxiliary motor then drives the disc back to normal, and a recording or indicating device is moved a distance proportional to this resetting distance. The instrument is arranged to bo connected in turn to a number of devices, such as pyrometers, and to record the readings in turn on a chart, the recording point being non- symmetrical in shape and being rotated slightly as each device is associated so that the records relating to the various devices may be identified.

Abstract: 1,187,742. Telegraphy. SIEMENS A.G. 27 June, 1968 [28 June, 1967], No. 30642/68. Heading H4P. In a telegraph exchange including a central control and in which each bit transition received at the exchange is transmitted over a multichannel line, common to all the subscribers, in the form of a pulse on a combination of the channels which is unique to the called subscriber, the loading on the exchange is determined and the exchange is blocked if a certain loading is exceeded. In one embodiment, Fig. 1 (not shown), each channel is connected to an OR gate whose output feeds two integrators. The integrator outputs pass to respective threshold units. The integrators determine the number of times the multichannel line is seized in the duration of one bit. Each is discharged by a respective clock pulse train at bit rate, trains being 180 degree phase displaced. If the threshold is exceeded an engaged signal is generated. In a second embodiment, Fig. 3 (not shown), the received data may have different speeds from different subscribers. The central control provides signals indicative of the number of seizings at each particular speed. The numbers are multiplied by factors indicative of the ratio of the speed to the lowest speed and the results summed. If the sum exceeds a certain value an engaged signal is generated. When a connection ceases the sum is decreased by the corresponding factor.

Title: Manufacture of condensation products of the anthracene series
IPC: C09B3/04
Filed: 1925-12-04
Abstract: Bz-methylbenzanthrones are obtained by condensing crotonic aldehyde with anthracenes containing an oxygen atom in the meso position, such as anthrones, anthranols, or oxyanthranols.  As condensing agent sulphuric acid may be used with or without an oxidizing substance such as arsenic acid or mercuric oxide or sulphate, and a diluent such as acetic acid or chlorobenzene.  The reaction may also be effected in two stages, the first of which, namely, the addition of the aldehyde to the anthranol, can be effected in the presence of sulphuric acid, hydrochloric acid, or a base such as piperidine, while the ring closure is effected by heating with aluminium chloride or a mixture thereof with sodium chloride.  The following examples are given:-(1) anthranol and crotonic aldehyde are condensed at 115-120 DEG  C. in a mixture of sulphuric and glacial acetic acids containing arsenic acid; the Bz-methylbenzanthrone formed is purified by distillation with superheated steam and freed from anthraquinone by treating with a reducing agent; (2) anthranol and crotonic aldehyde suspended in chlorobenzene are treated with gaseous hydrochloric acid at 0-3 DEG  C. and the resinous product further treated with an oxidizing and condensing agent as in (1); (3) a -oxyanthranol (m.pt. 133-135 DEG  C.) is condensed with crotonic aldehyde and the oxymethylbenzanthrone worked up as in (1); (4) anthrone and crotonic aldehyde are boiled in a mixture of pyridine and piperidine and the condensation product, after purification by solution in acetone, further condensed by heating with aluminium and sodium chlorides.  The Specification as open to inspection under Sect. 91 (3) (a) states that the products produced by the use of aluminium chloride contain chlorine.  This subject-matter does not appear in the Specification as accepted.

Abstract: 935,443. Injection moulding machines. E. G. HULTGREN. Aug. 28, 1961, No. 30993/61. Class 87(2). A machine for moulding e.g. lipstick cases comprises two mould parts between which is a mould cavity, and a core pin mounted so that it projects into the mould cavity when the mould is closed and is retracted when the mould is opened to strip the finished article from the core pin. Cavities 14, 15 in the fixed mould part 10 co-operate with cavities 18, 19 in the movable mould part 11 to form the mould cavity into which projects the core pin 20. The core pin 20 is mounted on a carrier 22 through the bore 26 of which passes an inclined cam rod 25 so that as the mould is opened the carrier 22 follows the rod 25 and retracts the core pin 20 from the mould cavity. On initial opening of the mould the core pin and carrier are kept in contact with the mould part 10 by means of springs 48 and the moulded article is thus removed from the cavities 18, 19. On further opening of the mould the moulded article is removed from cavities 14, 15, and thereafter the core pin is withdrawn and the finished article is stripped from the core pin. After initial opening of the mould the spruce will remain in cavity 31, from which it may be removed by a knock-out pin 50, the head 51 of which engages fixed pins 52, 53 as the mould continues opening. In a modification (not shown) the core pin and carrier can be reciprocated by fluid pressure or electrical means.
