Cellulose esters and ethers, processes for making filaments from.-Artificial silk &c. having filaments of the cellular or tubular type is obtained by extruding a solution of cellulose acetate or other ester or ether of cellulose into a cell or chamber through which passes a current of evaporative medium, and concentrating a supply of heat in the region of the extrusion dies as by the use of heated collector devices as described in Specification 300,998, so as to maintain in that region a temperature of the air higher than that necessary to produce the normal solid filaments. The temperature of the air in the other ports of the cell may be the same as or not substantially higher than that normally employed.

Title: Improvements in or relating to the drying of milk, milk products and milk mixtures
IPC: A23C9/15
Filed: 1935-07-31
Abstract: In the production of dried milk preparations from milk and liquid milk products, e.g. sweetened milk, milk containing a high proportion of fats or having starch products added thereto, or whey, in which the dried product contains less than 25 per cent by weight of casein, casein is added to the liquid to make the casein content at least 25 per cent by weight of the dried product, and the liquid is then dried on a roller machine.  The solids settle as a sheet on the drying rollers and can readily be detached and ground to powder.  The casein may be added in the form of soya bean flour which contains about 50 per cent thereof.  In an example, 3-5 per cent of soya bean flour is added to whey, and the mixture is homogenized and dried.

Title: Improvements in remote electrical system
IPC: G08C19/06
Filed: 1958-07-07
Abstract: 848,599. Electric telemetering systems. YARNALL-WARING CO. July 7, 1958 [July 11, 1957; May 7, 1958], No. 21720/58. Class 40(1). In a telemetering system the transmitter and receiver pointers are attached to the armatures of a transmitter and receiver transformer respectively, whose primary windings and secondary windings are connected in series aiding, the amplified secondary current being used to oppose a mechanical bias on the receiver pointer, any movement of the transmitter pointer producing an error signal in the secondary circuit which is used to reposition the receiver pointer, the mechanical bias on the receiver pointer causing it to move to an offscale position on failure the of power supply. As shown (Fig. 1) a pointer 22 whose position is to be telemetered is attached to the armature 25 of a transformer 26, and a remote indicator pointer 31 is attached to the armature 35 of a transformer 36, the transformer windings being connected in a circuit including a range adjusting transformer 48 and a zeroizing transformer 54. The four primary windings 27, 37, 50, 55 are connected in series aiding and fed from an A.C. source 60; the secondary windings 28, 38 are connected in opposition to the secondary windings 51, 56 to give a resultant current which after amplification at 67, is sufficient to energize a solenoid 40 to produce a force on pointer 31 to balance that produced by a weight 47, or by a spring. Any change in the position of pointer 22 produces a movement of armature 25 which alters the secondary current, and hence the energization of solenoid 40, and produce a corresponding movement of pointer 31 and armature 35 at which balance between the electromagnetic force and gravity forces on pointer 31 is restored. The movements of the armatures 25, 35 at the transmitter and receiver are in opposite directions. Zero adjustment is effected by a variable resistor 64 across windings 27, 50 or alternatively across windings 28, 51.

Abstract: 188,097. Roberts, J. T., Hardman, P. W., Roberts, W. S., and Railway Signal Co., Ltd. Aug. 16, 1921. Drawings to Specification. Staff, tablet, and ticket systems.-To provide for closing intermediate cabins on single track lines using token systems and to work several subsections, when required, as a long section, staff boxes for interchanging the staffs are provided at some or all the intermediate cabins which contain mechanically interlocked drawers each adapted to receive only an appropriate short section staff or the whole or a part of a long section staff, and in some cases to control contacts in the long-section line wire to render that useless when short-section working is in operation. For longsection working, a short section staff is withdrawn for each subsection and locked in the staff box either to release a portion of the long-section staff, which is then pieced together as a train proceeds through the section and collects the parts, or to release a drawer which controls contacts in the long section line wire. The return of the drawer in the latter case may be controlled by an electromagnetic lock controlled either from the remote end of the long section or from the next staff-box. The staff-boxes may be provided with an interlocked key which is released during long-section working for unlocking signal levers.

Abstract: The invention comprises compounds of the general formula <FORM:0825562/IV (b)/1> wherein m is one or two, R1 is hydrogen or methyl and R11 is hydrogen or a methyl or an oxo group and the preparation thereof by condensing a nitrocycloalkane of the general formula <FORM:0825562/IV (b)/2> with a compound of the general formula <FORM:0825562/IV (b)/3> wherein R is a methyl or a lower alkoxy group (one to eight carbon atoms), to form a compound of the general formula <FORM:0825562/IV (b)/4> and reductively cyclizing the formed compound to give a spiro-pyrrolidine of the invention.  In examples, nitro-cyclohexane is condensed with methyl acrylate in the presence of benzyl-trimethylammonium hydroxide to yield methyl b  - (1 - nitrocyclohexyl)-propionate which is hydrogenated in the presence of Raney nickel catalyst to give spiro-[cyclohexane-1,21-pyrroli-done-51], and which in turn is reduced by lithium aluminium hydride to form spiro-[cyclo-hexane-1,21-pyrrolidine].  Similarly is prepared methyl b  - (1 - nitrocyclopentyl) - propionate, spiro - [cyclopentane - 1,21 - pyrrolidone - 51] and spiro - [cyclopentane - 1,21 - pyrrolidine], the reduction to the pyrrilidone being carried out by hydrogenation under pressure in the presence of Raney nickel catalyst.
