Title: Apparatus for continuously forwarding moving tensioned webs of film with beaded edges
Inventor: ZYGAN HIERONYMUS
IPC: B21D43/11
Filed: 1964-01-28
Abstract: 1,033,093. Apparatus for stretching; shrinking heat-setting films. FARBENFABRIKEN BAYER A.G. Jan. 28, 1964 [Jan. 30, 1963], No. 3645/64. Heading B5B. An apparatus for guiding the beaded edges of a travelling web of film along two predetermined paths while the film is being, for example, transversely stretched, or caused to shrink transversely to a predetermined degree or is heat set under transverse tension comprises, as illustrated in Figs. 1 to 3 (not shown), endless travelling conveyer roller chains 3, 4 carrying members 5 and 6 which constitute the guide channels for the beads 2 of the film web 1. The chains 3, 4 are engaged by driven sprocketwheels 7 and are tensioned by means not shown. The channel members 5 and 6 are mounted on and form units with the chain links 8. The rollers 9 of the chain links 8 run on rails 10 extending along the whole length in which the guide channels are formed, the rails 10 forcing the channel members 5 and 6 into engagement with one another through pins 11, springs 12 and the screw 13. Each channel member 5 of the upper conveyer chains 3 has a protuberance fitting into a corresponding recess of the channel member 6 of the lower conveyer chains 4 with which it engages, the channel members 5 and 6 thus being brought into correct alignment with one another. The apparatus shown in Figs. 1 to 3 is for the stretching of a film web transversely in a continuous manner, and the transverse tension of the web is taken up by the ball-bearings 14 which travel along longitudinal channels in the upper and lower parts of the housing 15 attached to the vertical baseplate 16 by screws 17. The base-plates can be pivoted about vertical axes and thereby swung in a horizontal plane and adjusted to positions in which they are parallel, diverging or converging according to whether the film web during its travel between the plates 16, is to be prevented from shrinking transversely, stretched transversely, or allowed to shrink transversely to a predetermined degree.

Title: Brake systems for rail vehicles
Inventor: TONEY HOWARD
IPC: B60T13/46
Filed: 1960-02-03
Abstract: 900,044. Vacuum brakes. LUCAS (INDUSTRIES) Ltd., JOSEPH. Jan. 25, 1961 [Feb. 3, 1960], No. 3780/60. Class 103 (1). In a vacuum braking system in whicn a reservoir 2 is connected to the main pipe 1 through a non-return valve 3 and the reservoir is connected to a chamber 4a on one side of a brake-operating diaphragm 5, the chamber 4b on the other side of the diaphragm is normally connected to the main pipe 1 through a valve 6 which, in response to wheel locking, changes the connection from the chamber 4b from the main pipe 1 to the reservoir 2. The brakes are applied by a reduction in vacuum in the pipe 1 being transmitted through the valve 6. When a wheel-looking responsive means, such as described in Specification 880,767, moves the valve 6, communication between chamber 4b and pipe 1 is shut off and chamber 4b is connected to the reservoir 2, thus reducing the braking pressure. This reduces the vacuum in the reservoir and thus reduces the available braking effort during continued operation of the brake.

Filed: 1920-02-09
Abstract: 163,097. British Thomson - Houston Co., Ltd., and Clinker, R. C. Feb. 9, 1920. Frequency, inductances, capacities, and resistances, measuring.- A movable coil in inductive relation to a fixed primary coil, but having no conductive connection therewith, is connected to a condenser, and takes up a position in which the natural frequency of its circuit is equal to the frequency of the current in the primary coil, no mechanical controlling- device being provided. Frequencies may thus be directly measured. If the primary coil is supplied with current of definite frequency, the instrument may be used for measuring an inductance placed in series in the circuit of the moving coil, or a capacity or resistance placed in shunt to the condenser, the scale being correspondingly graduated. As shown, the movable coil 3 and fixed coil 2 surround a curved iron core 1. A balance weight 11 may be provided, or the arrangement may be duplicated, the two moving coils which balance each other being in series with a single condenser. A straight core may be used if the moving coil is of large aperture. In another form, the moving coil surrounds an iron cylinder placed between eccentrically-curved pole faces of an electromagnet carrying the primary winding. In series with the moving coil in any of the forms described there may be connected an inductance, or an additional fixed coil on the core. The moving coil may be mechanically connected to one element of a second and variable condenser in its circuit so that either the capacity alone or both inductance and capacity vary. The instruments are suitable for making graphic records.

Title: Novel unsaturated keto-esters and a process for the manufacture and conversion thereof
Filed: 1956-02-08
Abstract: The invention comprises unsaturated keto-esters of the general formula: <FORM:0789487/IV (b)/1> in which R1 stands for an alkyl radical containing from 2 to 4 carbon atoms, R2 stands for the methyl radical or R1 and R2, together with the carbon atom to which they are attached, stand for the cyclohexylidene radical.  The novel acetoacetates may be prepared by reacting a tertiary alcohol of the formula: <FORM:0789487/IV (b)/2> with diketene in the presence of a transesterification catalyst (e.g. pyridine, admixed if desired with acetic acid) or with an acetoacetic ester with or without a transesterification catalyst. Suitable tertiary alcohols are described in Specification 786,349.  The novel keto esters may be converted into unsaturated ketones of the general formula: <FORM:0789487/IV (b)/3> by heating at above 140 DEG  C., preferably at 150 DEG  C. to 180 DEG  C., whereby a loss of carbon dioxide and a rearrangement takes place. The unsaturated ketones may also be prepared with only transient existence of the acetoacetates by heating the tertiary alcohols with an acetoacetic acid ester in the presence of a transesterification catalyst, e.g. sodium methoxide, and preferably in the absence of a solvent.  In examples: (1) 3 - methyl - 6 - cyclohexylidene - hexen - (1) - ol-(3) in petroleum ether solution is reacted with diketene at 25-30 DEG  C. with stirring in the presence of pyridine and acetic acid and 3-methyl - 6 - cyclohexylidene - hexen - (1) - yl-(3)-acetoacetate is isolated and heated to 150-175 DEG  C. to evolve carbon dioxide and form 6-methyl - 9 - cyclohexylidene - nonene - (5) - one-(2); (2) 3,7,9-trimethyl-decadien-(1,6)-ol-(3) is similarly converted to 3,7,9-trimethyl-decadien-(1,6)-yl-(3) acetoacetate which is heated to yield 6,10,12 - trimethyl - tridecadien - (5,9) - one - 2; (3) 3,7 - dimethyl - nonadien - (1,6) - ol - (3) is similarly converted to 3,7-dimethyl-nonadien-(1,6)-yl-(3) acetoacetate which is heated to yield 6,10 - dimethyl - dodecadien - (5,9) - one - (2). Specification 786,350 also is referred to.
