Abstract: Paper is made by forming a thick stock cellulosic suspension, flocculating the thick stock by adding a relatively high molecular weight and relatively low cationic charge density polymer, diluting the flocculated thick stock to form a thin stock and then draining the thin stock to form a sheet. Usually coagulant is added to the thin stock before drainage and best results are achieved by adding coagulant followed by anionic colloidal material such as bentonite. The process can be operated to give good retention and good formation and, if the thick stock is dirty, to minimise pitch problems.

Abstract: 857,856. Gravity-separation apparatus. DORR-OLIVER Inc. Jan. 11, 1957 [Jan. 11, 1956 ; Feb. 24, 1956], No. 1157/57. Class 46. Feed liquid carrying solids is introduced at 46, Fig. 2, to a feed-distributing conduit 32 surrounding, at a location below the normal liquid level, a feed-well 25, which extends above and below the liquid level in a circular settling tank (not shown) incorporating rotary scrapers mounted on a shaft 17. Part of the stream is split off from the main stream at each of the overhangs O 1  to O 5 , Fig. 6, (which shows the conduit developed), each part being diverted by one of a number of curved members S 1  to S 5  through one of a number of openings 26 to 30 in the feed-well wall and thence through a mouth portion 33 having a vertically-adjustable cover plate 34. The remainder of the stream flows in similarly at 31. In Fig. 10 the feeddistributing conduit 49 comprises two channels 50, 51, each completely surrounding the feedwell 52 and each open throughout its length to the feed-wall interior. The main feed conduit 53 discharges into two branches 54, 55 communicating tangentially with channels 50, 51 respectively but on opposite sides of the feed-well so that the directions of liquid flow in the two channels are opposite. The channels are separated by a partition 56 whose inner margin lies outside the feed-well boundary. The purpose of the method is to rapidly disperse the influent energy of the feed and promote quiescence in the feed well.

Abstract: 555,011. Bomb-dropping apparatus. ASSOCIATED ELECTRIC LABORATORIES, Inc. Jan. 27, 1942, No. 1161. Convention date, Jan. 31, 1941. [Class 9 (ii)] [Also in Group XL] An impulse producing arrangement in an electric control for operating bomb release gear on aircraft comprises a valve with a relay in its anode circuit arranged to alter the grid potential of the valve. to cause the relay alternately to operate and release and produce impulses which operate the bomb release gear and also a manually adjustable counter which determines the number of impulses produced. The arrangement may be used to control bomb dropping mechanism in an aircraft to enable a predetermined member to be dropped with any predetermined interval. The valve t has a relay winding 60 in its cathode lead adapted to operate a contact 80 associated with the load and a contact 75 which controls grid-bias to render the system oscillatory. Timing is controlled by the resistance 73 associated with condenser 75a. The circuit is energized from a battery 10 switch 14 energizing the heater and pilot lamp 93 while switch 16 supplies energy to a vibratory high tension supply 26 and the winding 38 of a hold or relay which short-circuits the switch 16. In this way closure of switch 16 ensures a number of actuations determined by the setting of the counting mechanism 22 which then opens the circuit at contacts 20, 21 after it has been advanced step-by-step in response to each successive operation. The operation is substantially independent of temperature as the valve is preheated and in addition the spring 66 may be of material of zero temperature co-efficient. In a modification a pentode valve is used the electrodes being strapped for operation as a triode.

Title: Improvements relating to resilient materials
Inventor: GILDEA COLIN THOMAS
IPC: C08L75/04
Filed: 1957-01-12
Abstract: A bonded resilient material comprises a noncompacted mass of resilient fibres bonded together by a flexible solid reaction product obtained by reaction between (a) an organic compound having at least two -NCX radicals in its molecule, where X represents in the case of each radical either an oxygen atom or a sulphur atom, and (b) a monomeric ester having a molecular weight withint the range 200 to 10000 and having in its molecule at least two isocyanatereactive groupings.  By a "non-compacted mass" of resilient fibres bonded together is meant a mass in which air spaces account for a substantial proportion of the total volume, at least when the material is not under load.  Specified for compound (a) are toluene diisocyanate, with or without a triisocyanate such as triphenylmethane triisocyanate.  The -NCO or -NCS groups may be masked.  Non-dissociable reaction products still containing -NCS or -NCO groups, from polyhydroxy compounds such as di- or trimethylolpropane are also suitable.  As compound (b) there are mentioned a tri-ester of glycerol with a hydroxy acid, such as castor oil or ground-nut oil, or a diester obtained by partial hydrolysis of the tri-esters, or products of hydrolysis and subsequent re-esterification of glycerides.  Before use the bonding agent may be thinned with ethyl acetate.  It may contain as retarding agent adipic or stearic acid or an acid chloride. Shortly before application to the fibre a catalyst and cross-linking agents, e.g. primary diamines, glycols, pyridine, urea, cobalt naphthenate may be added.  An organo-metallic compound such as an alcoholate, ester or an alkanolamine chelate compound of titanium, vanadium, zirconium, aluminium or antimony may also be added to promote cross-linking. Fibres which may be bonded are straight or curled animal hair (especially hog and horse hair), coir fibre, casein fibre, nylon monofil and cactus fibre.  In making mouldings or bodies such as cushions, inserts such as bent, straight or helical springy steel strips or bodies of foam rubber may be incorporated.
Patent GB-599015-A (GB)
Title: Improvements in or relating to the preparation of triacyl pentoses
IPC: C07H15/12
Filed: 1945-01-16
Abstract: Triacylpentoses are obtained by heating a primary aromatic amine N-triacylpentoside in solution within a pH range between about 2 to 8 in the presence of water until hydrolysis is substantially complete, separating the liberated primary aromatic amine, e.g. by reaction in situ with an aldehyde, such as benzaldehyde, a substituted benzaldehyde or formaldehyde, or by steam distillation, and isolating the triacylpentose. Advantageously there may be added a small quantity of a volatile lower fatty acid, e.g. formic, acetic or propionic acid, or traces of strong acids, and a non-oxidizing atmosphere is desirable.  The hydrolysis is applicable equally to the two types of primary aromatic amine N-triacylpentosides obtained by acylating the respective products obtained by effecting condensation of the aromatic amine and the pentose (e.g. ribose), (a) by applying heat, and (b) at room temperature.  The term "acyl" is used to denote acyl residues of the lower fatty acids, and of the benzene series, e.g. acetyl, propionyl, benzoyl, p-methoxybenzoyl and p-nitrobenzoyl. In examples: (1) a -2 : 3 : 4-triacetylaniline - N - d - ribopyranoside in ethanol is added to 0.5 per cent aqueous acetic acid, the mixture is steam-distilled to remove aniline, and the aqueous decolorized filtrate is evaporated to dryness in vacuo to isolate 2 : 3 : 4-triacetyl-d-ribose; (2) a -2 : 3 : 5-triacetylaniline - N - d - ribofuranoside 0.5 per cent aqueous acetic acid, is steam-distilled, and subsequently treated as in (1) to isolate 2 : 3 : 5-triacetyl-d-ribofuranose. Specification 599,013 is referred to.  a  - 2 : 3 : 5 - Triacetylaniline - N - d - ribofuranoside is obtained by treating a -aniline-N-d-ribofuranoside (prepared by heating a -aniline-N-d-ribopycanoside in alcohol) in dry pyridine at 0 DEG  C. with acetic anhydride.

Abstract: 431,699. Road - traffic signals on vehicles. LUCAS, Ltd., J., and EGGINTON, W. H., Great King Street, Birmingham. Jan. 15, 1934, No. 1393. [Class 118 (ii)] A switch for a direction indicator is set by hand to one of its two operative positions and is locked by a cam engaging a corner of a channel section plate, the lock being removed by the return movement of the steering-wheel operating a spring-controlled rod bearing the cam, to allow the switch to be restored by its spring. As shown in the drawing the switch, mounted on arm a secured to the steering column, is set by rotating the handle f so that the cam s engages one of the corners p on the flange o of plate n which is rotated with the switch and holds the switch in its operated position, as shown, against action of its restoring spring. When the steering wheel is moved to make the turn the cam x carried by the wheel rides over the pawl t but on the return movement of the wheel the cam forces the pawl t and with it the arm q and cam s away from the steering column against the pull of spring r. The cam s is thus moved out of the corner p allowing the switch with its operating handle f and holding plate n to return to its normal position under action of its restoring spring.
