Title: Improvements relating to means for registering and/or recording the load readings of cranes and the like
IPC: G01G23/18
Filed: 1933-04-25
Abstract: 418,987. Recording and registering apparatus; weighing apparatus. EAST FERRY ROAD ENGINEERING WORKS CO., Ltd., and KIBBLER, H., East Ferry Road, Millwall, London. April 25, 1933, No. 12102. [Class 106 (iv).] The load on a crane is registered and/or recorded when a follower member completes a circuit by engaging a weight-indicating pointer, a motor driving the follower and the registering and/or recording mechanism through a clutch or friction drive, the motor circuit being closed and the drive connected by means independent of the weighing mechanism, the motor circuit being opened and the drive disconnected upon the engagement of the follower and the pointer, whereupon the follower is returned to its initial position by independent means. The crane load is indicated by the pointer a of a hydrostatic gauge. When a registering and/or recording operation is to be effected, a switch m is manually closed. This completes the circuit of a motor C through lines 1, 2, 3, 4. It also completes the circuit of an electromagnet k which connects the motor C through a friction drive d to a shaft g which drives the follower b, the register f and the recorder e. The circuit of the electromagnet k is completed from the switch m through 1, 2, 6, k, 8, n<1>, 4. While the follower b is overtaking the pointer a the registering mechanism f is driven and the recorder printing wheels are advanced to a setting corresponding to the load. The switch m is meantime held closed by a retaining coil m<1>. When the follower overtakes the pointer, contacts a', b<1> close a circuit 11, 12, 13, n, 14, b, a, 4, the coil n opening the contacts n<1> whereby the holding coil m<1> and the electromagnet k are de-energized, the latter disconnecting the friction drive d. The coil m<1> allows the switch m to open, a tail m<3> on the switch arm momentarily closing contacts m<4> to complete a circuit to an electromagnet r which operates the printing mechanism q of the recorder e whereby the load is printed on a record strip. When the friction drive d is disconnected a spring o returns the follower to its normal position, the type wheels of the printer being zeroized and the register f retaining the registration by reason of a ratchet mechanism f<1>. While the follower member is overtaking the pointer, a red lamp l is lit. A relay may be provided to prevent a second recording of the same load before the pointer a has returned to zero. Another lamp may be lit until the pointer does return to zero.

Title: Improvements in or relating to a method for insolubilising artificial filaments, threads, fibres and the like obtained by the spinning of solutions of proteins
Inventor: DAVIDSON WALTER LAMB
IPC: D01F4/00
Filed: 1954-04-28
Abstract: <PICT:0762401/IV(a)/1> A continuous travelling tow of protein filaments, obtained by spinning aqueous alkaline solutions of vegetable seed globulins and (or) phospho-proteins into a sulphuric acid-sodium sulphate bath, is insolubilized under substantially tension-free conditions by impregnation first with a concentrated solution at a pH up to 7 of at least one salt which is a non-hardening agent for protein, the solution being retained in contact with the filaments at a temperature between 40-98 DEG  C. until a sample on washing and drying gives discrete filaments, and then at a raised temperature (70-98 DEG  C., preferably 90-98 DEG C.) with a strongly acidified aqueous formaldehyde solution containing at least 340 gms. sodium sulphate and 200 gms. sulphuric acid per litre, and preferably also containing sodium chloride.  The total treatment time with the two insolubilizing solutions is 1-30 minutes.  The salt, which is a non-hardening agent, preferably has a concentration of more than 10 per cent, and may be an alkali metal salt of hydro-chloric, sulphuric or phosphoric acid or ammonium or magnesium sulphate; this solution may additionally contain a colour-improving agent such as sodium chlorite, sodium formaldehyde sulphoxylate or sodium dithionite.  As shown, a tow 3 is obtained by spinning a globulin solution into the sodium sulphate-sulphuric acid bath 2.  The filaments are stretched by godets 4, 5 and by godets 6, 7 immersed in another sodium sulphate sulphuric acid bath 8, and then pass to godets 10, 11 which are immersed in the slightly alkaline bath 12 (pH8-9) containing sodium sulphate and sodium chloride at 25 DEG  C.  The emerging filaments have liquid adhering to them of pH3-6 and pass to a ring trough 13 (which slowly rotates) immersed in a bath of the same salt concentration, but at pH 4 and a temperature of 70 DEG  C., in which they stay for about 10 minutes for the first stage of the insolubilization.  The filaments then pass to a constant feed cone 20 and tube 24 for the second and final stage of the insolubilization with a solution of sodium sulphate, sodium chloride, sulphuric acid and formaldehyde at a temperature of 85-90 DEG  C., the second stage being completed in about 7 minutes.
