Patent GB-660277-A (GB)
Title: Improvements in or relating to the production of finely-divided cellulosic material
IPC: D21B1/06
Filed: 1948-09-03
Abstract: Relates to a process for the production of a cellulose powder suitable as a raw material for conversion into cellulose derivatives or as a filler, wherein a fibrous cellulose is mechanically reduced in particle size in water and the resulting comminuted fibrous hydrated cellulose is mechanically dewatered and is dried, and consists in subjecting the dewatered comminuted fibrous hydrated cellulose to drying by evaporation while applying mechanical forces which prevent the formation of a dry mass or cake and effect the continuous exposing of fresh surfaces to the atmosphere, the said mechanical forces being applied at least until the product is dried to a powder form.  In an example 12 parts of wood pulp (91 per cent alpha-cellulose) are put into a pulper with 260 parts of water and pulped for 3 hours.  At the conclusion of pulping the slurry is dewatered in a centrifuge to a moisture content of 72 per cent.  The centrifuge cake is transferred to a steam heated Werner Pfleiderer Incorporator and heated with continuous agitation until the moisture content is 35 per cent, by which time the cellulose is in a finely divided powdery condition.  In a second example in which the materials are pulped for 6 hours and centrifuged to a moisture content of 80 per cent, the centrifuge cake is treated in a steam heated Werner Pfleiderer Incorporator until dry.

Title: Improvements in and relating to the production of artificial filaments, threads and the like
Inventor: TALLIS ERNEST EDWARD
IPC: F23R3/60
Filed: 1952-09-18
Abstract: In the production of artificial filament s threads, fibres and like products by the extrusion of viscose into an aqueous coagulating bath containing sulphuric acid, sodium sulphate and zinc sulphate, products having a thicker skin, a non-crenulated surface and a reduced water-imbibition and gel swelling factor are obtained by adding to the viscose at least 0.1 millimole per 100 gms. of the viscose of a dithiocarbamate having the formula <FORM:0739072/IV (a)/1> where M is a monovalent metal or a monovalent basic radical, R1 is hydrogen or an aliphatic hydrocarbon radical and, when R1 is hydrogen, R is an aliphatic or cycloaliphatic hydrocarbon radical or a monoalkylene monoamine chain or a dialkylene monoamine chain or a polyalkylene polyamine chain or a substituted polyalkylene polyamine chain and, when R1 is an aliphatic hydrocarbon radical, R is an aliphatic or a cycloaliphatic hydrocarbon radical or an aliphatic hydrocarbon radical joined to R1 to form therewith a closed aliphatic hydrocarbon chain, n is 1 or more and R has the same valency as n. The process also enables unripened viscose to be spun.  Specified dithiocarbamates are the sodium salt of 2-aminoethyl dithiocarbamate, di-sodium ethylene bis-dithiocarbamate, the disodium salts of the bis-dithiocarbamates of polyamines such as diethylene triamine, triethylene tetramine, tetraethylene pentamine and pentaethylene hexamine, sodium pentamethylene dithiocarbamate, sodium dimethyl dithiocarbamate, sodium cyclohexyl dithiocarbamate and diethyl ammonium diethyl dithiocarbamate.

Title: Safety devices for powered machines
IPC: F16P3/06
Filed: 1973-05-17
Abstract: 1460902 Machinery guards HWL ENG Ltd 9 May 1974 [17 May 1973] 23560/73 Heading F2J A powered, electrically-controlled machine, such as a paper guillotine, has a sweep-away safety guard coupled to a safety switch in the control circuit, such that the machine cannot be operated until the safety switch becomes closed upon the completion of each sweeping operation of the guard. A stack of paper sheets on table 1 becomes held beneath a clamping press (not shown), for cutting by a downwardly reciprocating knife (not shown) at the aperture 2, and a U-shaped pivoted safety guard 3 is first caused to swing forwards and upwards before the clamp and knife operate, in order to sweep away an operator's hand or limb, or other article, from the danger area beneath the clamp and knife. The sweeping movement of the safety guard may be actuated by a solenoid 6 which is energized by simultaneous pressure on two push-button switches 7, 8, spaced apart so that the operator must use both hands. When the safety guard 3 reaches the end of its sweeping motion, cams 9, 10, secured to its pivots 4 cause cam switch contacts a, b and c<SP>1</SP>, d<SP>1</SP> to become closed, thereby completing an interlock circuit, Fig. 2, which initiates a machine switching sequence by energizing a clamp-down relay 16 via clamp-up switch contacts 15, and also starting a timer 13 which subsequently operates a timer relay 14. Contacts 17 on relay 16 close to energize a knife auxiliary relay 18, which in turn closes contacts (19) in the circuit of a knife motor relay (20), Fig. 4 (not shown). This knife relay (20) can however become energized only after further conditions have been met, involving "non- repeat relay" (24, 25), timer relay contacts (26), and mechanically-linked manual safety switches (27, 28) which are also related to a brake relay (29).
