Filed: 1927-03-07
Abstract: 307,126. Lambert, F. T. March 7, 1927. Addition to 266,813. Cutting slices in succession.-The means for controlling the compensating movements of the meat holder described in the parent Specification are modified, and comprise a lever arm, pivoted to one side of the feed table and extending across the feed table to engage in anchoring means. The lever arm engages the swinging meat hobler at an adjustable position to one side of the pivot of the meat holder. As shown in Figs. 1, 3, a last slice holder f is carried by a frame f<1> pivoted in lugs c<3> on a frame c which is supported on the usual uprights d. The other end of the frame f<1> is coupled to the frame c by a folding hinge member f<2> which assists in supporting the holder. A lever arm h is pivoted at g to the lug c<4> of the frame c and extends across the feed table to engage in a bifurcated guide i rotatably mounted on a rod i<1> and is retained in the raised position by a spring-pressed pin i<2> engaging in a circumferential groove in the rod i<1>. The lever h is connected to the holder f by a pin k engaging in a slot k<1> in the top edge of the frame f<1>. The point of connection is adjustable, to suit the initial shape of the meat being sliced; by moving the sleeve j, carrying the pin, along the lever h by rack and pinion mechanism i<1>, j<2>. A clamping screw j<3> is provided. In a modification, Fig. 7, the pivots g, e of the lever and meat holder are on the same side of the feed table. In a further modification, Fig. 8. a horizontal meat table m is pivoted on the clamp post o, and is angularly 'adjusted by the bar h pivoted at g and working in the stationary guide i. The adjustable clamp i carries a pin which works in a slot q in a bracket p on the meat table.

Title: Improvements in or relating to methods for the transmission of weather charts
IPC: G08C21/00
Filed: 1965-02-15
Abstract: 1,100,979. Transmitting weather information. R. HELL. 15 Feb., 1965 [14 Feb., 1964], No. 6488/65. Heading H4F. In a method of transmitting the information plotted on a weather chart, coded electrical signals representative of the various meteorlogical symbols, curves, &c. only are transmitted and at the receiving end such signals are decoded and utilized to control the recording of the appropriate symbols &c. on a weather chart blank. To effect the transmission the chart, on which the various " iso " curves have already been plotted, is covered by a regular mesh network and the various symbols, numerals &c. are then entered by manual plotting (e.g. by the use of standardized stamps) such that only one symbol is contained in any one mesh. The chart is then optically scanned mesh-by-mesh along consecutive lines and the various symbols &c. encountered are successively compared optically with all the symbols in a store, containing all the standardized symbols together with a plurality of straight line elements (Fig. 2, not shown) approximating to portions of curves lying in a single mesh. Code combinations of electrical pulses representative of the identified symbols are then transmitted, if necessary after temporary storage on a magnetic drum where the speed of identification is slower than the transmission rate, and after decoding at the receiving station are utilized to control the deflection of the beam of a special cathoderay tube, e.g. of the " Charactron (RTM) type, to recreate the symbols as luminous images on the screen thereof. A positively charged selenium layer carried by a rotating metallic drum is then exposed to the images which discharge the exposed areas of the layer so that when positively charged xerographic powder is sprinkled on the layer it adheres to such areas. The " powder picture " is then transferred to a weather chart blank as shown in Fig. 1, on which it is " fixed " by means of infra-red light which fuses the powder particles with the paper.

The contour of the surface 15 of the rotor is determined by an equation involving the distance from the shaft 13 to the outer surface of the leading face 18 of the rotor, the diameter L of the rotor at the inner edges of the blades .14 and a distance dy from the leading tips 22 of the blades to a plane X-X through the rotor at right angles to the shaft 13. The leading face of the housing 11 is curved from the edge 25 to its throat 26 to produce a venturi effect and the radius of curvature of this face should be at least a quarter of the diameter of the throat 26. The diameter of throat 26 is about equal to or slightly less than L, and the curve of the surface inside the throat is shaped according to a formula O = #Ldy + L<2>/4 , where O is the distance 4 of the surface from the shaft 13. The exhaust of the engine driving the rotor may be led into the air entering the blades to heat same.

Patent GB-370151-A (GB)
Title: Improvements in electric heating devices
IPC: C04B28/24
Filed: 1931-03-06
Abstract: A heating element consists of a resistance wire embedded or enclosed in, or supported by, a refractory body consisting of silica or other refractory material bound by means of silica and free from substances capable of electrolysis in presence of water. Powdered silica or sillimanite which has passed through a sieve with 60 meshes to the square inch is washed free from salts and mixed with a cement of silica derived from silicon ethyl ester so as to yield a paste in which the heating element is embedded. Alternatively the paste may be moulded into the form of a core to which the resistance wire is fitted externally.  A thin layer of the paste may then be coated over the wire.  The whole is allowed to dry in the air for several hours, and may then be heated by passing a current through the wire for a short time.  The setting of the refractory body may be hastened by burning off the alcohol from the paste.  In an example, 2 kilos of powdered sillimanite are mixed with 270 c.c. of silica solution prepared from silicon esters as described in Example 1 of Specification 290,717, [Class 22, Cements &c.].  The mixture is placed in a mould, the resistance wire placed on the layer thus formed, and covered with a further layer of the mixture, and the whole is allowed to set with or without pressure.  After drying, the mass is warmed by passing current of about half the maximum load through the resistance for three minutes, the plate then being set aside to harden.  In a second example, 200 grams of powdered sillimanite are mixed with 100 c.c. of the silica solution, the heating element is dipped into the paste so obtained, the alcohol is removed by ignition, and the sillimanite insulator left as an adherent coating round the wire.  This operation is repeated to build up an insulating layer.  An iron casting may be lined with the paste, the insulated element inserted, cemented into position by covering with the paste, and the whole allowed to set. Alternatively the moulded composition may be made in two parts which, when fitted together, form a compartment in which the heating element is arranged.
