Title: Improvements in or relating to apparatus for measuring time intervals
IPC: G04F8/00
Filed: 1937-04-14
Abstract: 493,912. Measuring time intervals ; timing races. GRASEBY, R. C. April 14, 1937, No. 10601. [Class 139] [Also in Group XIX] Apparatus for measuring time-intervals (e.g. timing races) comprises a rotatable gear wheel 2 driven at constant speed, a normally stationary gear wheel 3 acting as stop member, a second rotatable gear wheel 4 operatively connected to an indicator 16 (not shown) and normally engaging the stop wheel 3, means whereby wheel 4 is disengaged from stop wheel 3 and engaged with wheel 2 for the time interval to be measured and means for adjusting the stop wheel 3, whilst engaged by wheel 4, to zeroize the indicator. The contrate wheel 2 is driven directly by a synchronous motor 1 and the wheel 4, which is permanently geared to a indicator needle 16, Fig. 2 (not shown), is carried by the lower end of a lever 8, pivoted at 9 and pulled to the right by armature 10 and normally energized magnet 11 against spring 12. This holds wheel 4 in mesh with a contrate stop wheel 3 which is normally stationary but may be rotated by knob 20 to zeroize the indicator needle. An impulse at the beginning and end of the time interval to be measured de-energizes and energizes the magnet 11 respectively, so that during the interval the wheel 4 is in mesh with the constantly driven wheel 2. Parts 26-28 permit adjustment of spring 12. The magnet 11 may be normally de-energized and the spring 12 then holds wheel 4 normally against the stop wheel 3. The wheel 4 may be displaced mechanically by push buttons acting directly or indirectly on the arm 8. To isolate the first and last impulses marking a time interval from intermediate impulses, the device of Fig. 4 is used, e.g. the first and last of ten impulses as in testing the dials of automatic telephone installations. A normally de-energized magnet 30 drives, through arm 32 and pawl 34, a ratchet wheel 35 rigid with a cam 39 and having ten teeth in the angular distance between two successive notches 40 of the cam. The lower of two contacts 41, 42 carries a block 43a having a pin 43 which rides on the edge of the cam. The winding of magnet 30 is in the circuit in which the impulses are produced and contacts 41, 42 are in circuit with magnet 11, Fig. 1. Cam 39 is set, by pin 48, so that a notch 40 is opposite the pin 43 and contacts 41, 42 are closed; magnet 11 is energized and wheel 4 held against wheel 3. Immediately the first of the ten impulses is received by magnet 30, pin 43 is forced out of notch 40, contacts 41, 42 open and wheel 4 leaves wheel 3 and engages the running wheel 2. This persists until at the tenth impulse the pin 43 rises into the next notch 40 and magnet 11 is re-energized to re-engage wheels 4 and 3.

Title: Improvements in and relating to the production of artificial filaments, threads, fibres, bands and the like
Inventor: WORMELL ROBERT LOUIS
IPC: D01D10/04
Filed: 1950-05-03
Abstract: Freshly - extruded protein threads are hardened in a bath containing formaldehyde and one or more metal salts until the threads become resistant to the solvent or swelling action of cold water.  They are then treated in a bath comprising methyl alcohol or ethyl alcohol, together with an esterification catalyst, to effect esterification of the threads, and the esterified threads are subjected to a curing treatment consisting of either a further hardening treatment in a bath containing formaldehyde and one or more metal salts or an insolubilizing treatment, i.e. a treatment to render the threads resistant to the solvent or swelling action of hot water and hot aqueous liquids.  The esterification may be effected at 35-50 DEG  C. and the catalyst may be sulphuric acid or ethyl or methyl sulphuric acid.  The hardening bath may be one containing formaldehyde and sodium, aluminium, or magnesium sulphate and, if desired, sulphuric acid.  The insolubilizing agent may be acetic anhydride, or a compound giving rise to cyanate ions, or aluminium sulphate.  After treating with a cyanate, the threads are preferably submitted to a heat treatment at 60-70 DEG  C.  The pre-hardened threads may be knitted, woven, or otherwise formed into fabrics and then submitted to the esterification and curing treatments.  The esterification liquid may contain water in a proportion not exceeding 30 per cent based on the weight of the alcohol.  It may also contain a dialkyl sulphate, e.g. diethyl sulphate, e.g. in a proportion of 30 per cent based on the weight of the alcohol.  The esterification liquid may be aqueous alcohol (75-80 per cent of alcohol to 25-20 per cent of water) containing 160-240 grams per litre of sulphuric acid.  The pre-hardened threads may be pretreated with alcohol immediately before the esterification step.  The treatment reduces the water-imbibition of the threads and gives greater fastness to dyeings.  The treated threads are stable to hot acid dyebaths.  In an example, threads are obtained by extruding an alkaline solution of milk casein.  After hardening in formaldehyde, the threads are stretched and then further hardened in a solution of formaldehyde and sodium sulphate.  The threads are esterified by treatment with ethyl alcohol and sulphuric acid, and then further hardened with a solution of formaldehyde and sodium sulphate.  In another example, threads of peanut protein are treated.  In other examples, the curing of the esterified threads is effected with a solution of sodium cyanate. Specifications 467,173, 495,885, 614,506 and 690,501 are referred to.

Crucible and metalheating furnaces. -A gaseous mixture of air and fuel in self-burning proportions is delivered by appropriate mixing- devices to annular or elongated combustion chambers with narrow outlets through which the flames issue into the heating-chambers. The products of combustion are discharged downwardly through conduits arranged to jacket the heating- chamber. Fig. 1 shows a crucible furnace wherein the crucible is supported on a block m which forms with the wall of the furnace an annular combustion chamber o and a narrow slot q connecting it to the furnace chamber. The air and fuel mixture is delivered tangentially to the space o, and the combustion products pass away through the jacket e and outlet l. In adapting the invention to a rectangular heating-furnace, Fig. 3, the floor is formed by a block 5 with inclined edges, forming with the furnace walls long slits 9 and combustion chambers 6, which are fired by two diagonally-opposite fuel and air supplying nozzles, supplemented, if necessary, by similar nozzles at the other corners. In applying the invention to a tall, tubular billet heating furnace such as described in Specification 9568/15, a series of annular combustion chambers 15, Fig. 5, are superposed around the heating chamber. These are fired each by a nozzle 18 tangentially arranged, and the burning gases pass through slots 16 to the heating chamber 17, and thence to the jacket 20, through which they pass downwards to the outlet. In a modification of this furnace, the combustion chamber 15 is a continuous helical chamber of considerable pitch, nozzles 18 being situated at intervals.
