Title: Improvements in or relating to the treatment of edible fats
IPC: A23D9/02
Filed: 1921-03-01
Abstract: 181,077. Douglas & Sons, Ltd., W., and Nicol, J. S. March 1, 1921. Emulsions, making.-Edible fat such as lard or lard compound is strained and homogenized by forcing it through perforations and grooves in and spaces between two or more concentric hollow cylinders, one or more of which may be rotated. In the form shown, fat from the usual pickertrough 2, Fig. 5, is forced by a pump 3 to a casing 1 containing slightly tapering cylinders 4, 5, 6, Fig. 1, formed with perforations 9, shallow grooves 11, and deaper grooves 10, which may have serrated edges. Fat is forced into the annular space 7, and passes through the perforations, grooves, and spaces between the cylinders to the interior of the inner cylinder and thence to the valve controlled outlet 16. The valve 17 on the outlet 16 is interconnected with a valve 21 on a by-pass pipe 20, so that when the outlet 16 is closed the valve 21 is opened and the fat circulates back to the pump without passing through the cylinders. The inner cylinder 6 is rotated by a shaft 13, the outer cylinder is fixed, and the central cylinder may be fixed or may be loosely mounted so as to be rotatable bv friction. In modifications the inner of two cylinders, or the central cylinder, or both the inner and the central cylinders may be rotated. The Provisional Specification also describes a form of apparatus in which the fat passes through two or more perforated and grooved plates, one or more of which may be rotated.

Title: Improvements in or relating to electric motors
IPC: H02P7/00
Filed: 1942-05-20
Abstract: 558,914. Control of D.C. motors. MORRIS, E. H. May 20, 1942, No. 6886. [Class 38 (iii)] A motor 10 driving a load which may overrun in one direction, e.g. a blade-adjusting device of a variable pitch propeller, has two series fields 11, 12, one for each direction of rotation, controlled by a two-way switch 13, 14, 15, the contact 15 of which may be moved by an engine speed governor. During drive in the overrun direction, e.g. adjusting the propeller to fine pitch, the series winding 11 is energized and contactor 19, 21 converts the winding 12 into an aiding shunt field in series with a resistance 18 which may be an aiding auxiliary field winding of the motor. If the load overruns a braking current circulates in the field 12, and eventually the current in the field 11 drops to zero. whereupon contactor 19 opens, the motor thereupon ceases to develop a back E.M.F. and a brake coil 22 releases a spring-applied brake. The brake release coil 22 may be in series with the field 22.

Title: Manufacture of new polymers
IPC: C08F20/00
Filed: 1946-03-06
Abstract: One or more unsaturated monomers containing an aldehyde group masked either by ether groups or by an ether group and a halogen, said group being inactive in polymerization and readily convertible to an aldehyde group by hydrolysis, alcoholysis or saponification, are polymerized in known manner to linear polymers.  Catalysts, e.g. benzoyl or diethyl peroxide or ammonium persulphate, which may be activated by sodium bisulphite or metabisulphite, may be present. Specified monomers are aerolein acetal and butyral, the acetals of methacrolein, phenyl acrolein, crotonaldehyde, cinnamic aldehyde, and allylidene ethoxide-chloride.  They may be interpolymerized with vinyl acetate, thioacetate, chloride, cyanide, fluoride, carbazole and pyridine; butadiene, chloroprene; styrene; methyl acrylate and methacrylate; vinylidene chloride; ethylene, vinyl acetylene, isobutylene.  The second monomer may contain masked hydroxyl groups, e.g. as in vinyl acetate.  On hydrolysing such an interpolymer in alkaline media, the ester groups only are removed, but in acid media the ether groups are also removed and the free hydroxyl and aldehyde groups cross-link to form an insoluble, infusible product.  The masked aldehyde polymers may be spun into filaments or cast into films or used as coatings and adhesives. Specification 562,092 is referred to.

Title: Improvements in or relating to high frequency electrical conductors or radiators
IPC: H01P5/10
Filed: 1938-03-07
Abstract: 515,684. Wireless signalling ; aerials; artificial lines. BLUMLEIN, A. D. March 7, 1938, No. 7066. [Classes 40 (iii) and 40 (v)] [Also in Group XXX-X7I] A high-frequency transmission-line, which also acts as a radiator, consists of a metal conducting tube 1, Fig. 1, of copper with a longitudinal slot 2. The tube forms a "channel for the transmission of magnetic flux," and is equivalent to a line having inductance in series, and shunted by elements of inductance and capacity in parallel. High-frequency signalling currents may be fed to the line by a coil 4, or by leads 4a connected across the slot, and are taken off by a coil 5. Flux leakage across the slot may be regulated by a plate 6, Fig. 2. Or the size of the slot may be adjusted, in order to tune the line to the working frequency, as shown in Figs. 3 and 5. The tube may be used as a transmitting aerial, giving maximum radiation at rightangles to its length, and comparatively little radiation axially. It is equivalent to a singleturn loop or frame, one wavelength long. The feed may be central or at one end. As shown in Fig. 6, the tube 7 is supported at voltage nodes 9 from a hollow mast 8, and is fed with signal energy at points 10, 11, half a wave length apart, from leads which are led up through the mast as shown in Fig. 7. A tube with a diameter of from six to twelve inches is suitable for transmitting a wavelength of 5 metres, though tubes of greater diameter, provided with more than one slot, may be used for covering a wide frequency-range.

Title: Improvements in apparatus for testing and recording the cutting efficiency of saw blades
IPC: G07C3/12
Filed: 1920-03-11
Abstract: 164,503. Herbert, E. A., and Fletcher, C. March 11, 1920. Recording particular operations.-A sawing machine is provided with a recorder for showing the number of strokes, or the time, taken to perform each cut, and also the number of cuts completed. The chief use of the apparatus is to record the performance.of saws in cutting standard pieces, and thereby to test their efficiency. As applied, for recording the number of strokes and cuts, to the hack-sawing machine described in Specification 17372/13 [Class 145 (ii), Wood, Working], a cam c rotated by the repeat shaft of the machine controls a lever o pivoted at o<3> and bearing by means of a spring plunger n upon one end of an endwise movable spindle j<1>. The saw reciprocating crank-shaft of the machine is provided with a cam which at each rotation reciprocates a pawl f<1> engaging a ratchet wheel h and so through reducing gearing rotates a spur wheel j fixed on the spindle j<1>. A friction disc k and a pinion l are loosely mounted on this spindle, and when the lever o is in its opertive position the pinion l is driven by the wheel j and raises a rack m carrying a pencil p bearing against a chart drum q. When a cut has been completed, the lever o is shifted and so releases the pinion l and allows the rack and pencil to fall to initial position. The drum q meanwhile has been rotated one step by a pawl r' engaging a ratchet wheel r and carried by a spring controlled arm s pivoted on the lever o. The fall of the rack m is cushioned and adjustably limited by a resilient pad g and a co-operating screwed pin m<1> adjustable on the rack. The pencil may be actuated by a clock instead of by the machine. and in the case of non-automatic machines the rotations of the drum and the release of the pencil may be effected by hand.

Abstract: 1,254,601. Endless conveyers. SCHWEIZERISCHE INDUSTRIE-GES. 12 Feb., 1969 [13 Feb., 1968], No. 7518/69. Heading B8A. A device for separating contiguous, flat objects 3 moved forward in a continuous row by a first advancing means 1 and for further advancing the objects, uniformly spaced, by a second advancing means 4, comprises a control means 12. The latter is positioned between the first and second advancing means for adjusting the movement of the foremost object 3 from the first advancing means 1 so that it moves at the same velocity as the second advancing means 4. At least one first gripping means 13a, 13b is operated synchronously with the second advancing means 4 and is movable in a closed path 18 which includes over a part of its length, the path of forward movement of the foremost object. Thus the object is gripped over at least part of this common path length and is accelerated with respect to the first advancing means 1 to the second advancing means 4, and is there released. The control means 12 is carried by arms 10 and 11 which are operated by respective cam mechanisms (not shown) in synchronism with the drive of the second advancing means 4. As shown, the latter is an endless chain conveyer, but it may alternatively be in the form of a pair of reciprocating pushers. The means 12 carries two buffers 29 for engaging the leading object 3, and grippers 13a, 13b. The gripper 13a is a fixed part of the means 12, while the gripper 13b is pivotally mounted on the latter. A cam 17 engages a follower 16 connected to the gripper 13b so as to cause it to engage the object 3 after it has been engaged by the buffers 29. As shown, there is a second means 12 having associated grippers 13<SP>1</SP>a, and 13<SP>1</SP>b, operating alternately with the first means 12. Grippers 24, 26, associated with the conveyer 1 operate to grip each object 3 immediately following an object 3 being engaged by the means 12. The grippers 24, 26 move along a slide 21 at the speed of the conveyer 1 and prevent a double feed of the objects 3.
