Title: Improvements in and relating to bleaching of proteinaceous materials
IPC: D06L3/08
Filed: 1947-03-19
Abstract: Wool or other proteinaceous materials of animal origin such as hair, fur, feathers or untanned skins, are bleached with an aqueous solution of alkali metal or alkaline earth chlorite brought to a pH from 4 to 5 by previous acidification, the value of the pH being maintained during the operation, if necessary, by the presence of a buffer, e.g. acetic acid.  A wetting agent may be added to the solution, e.g. a fatty acid ester of polyglycol or polyglycerol or an alkyl sulphonate.  For the treatment of wool the preferred wetting agents are sodium oleylsulphonate, octylphenoxy (8) glycol of the formula CH3(CH2)7C6H4O(CH2CH2 O)7CH2-CH2OH, octylsulphophthalate and triethanolamine.  In the examples, degreased wool, a rabbit's skin, degummed silk and depilated calf skin are bleached.

Title: Improvements in or relating to record-card-controlled statistical machines
Filed: 1925-03-25
Abstract: 231,498. British Tabulating Machine Co., Ltd., (Assignees of Lake, C. D.). March 26, 1924, [Convention date]. Addition to 190,144. Statistical machines; printing totals; adjusting for computing or recording only.-The machine according to the parent Specification, which included means for total-printing on resetting of the counters, is modified by the provision of means for total-printing without listing and means for subtotal-printing. The invention is described as applied to the machine described in Specification 216,142. The common connecting line 126 from contacts T5 to the common bars 103 of the various banks of printing magnets in the apparatus described in Specification 216,142, is replaced in the present invention in the case of banks 3, 4, and 5 by lines 126<a>, 412, 413 and 415 and hand-operable non-list switches 409, 410 and 411. If switch 410, say, is opened registering occurs in bank 4, but listing of the items is suppressed since the circuit from bar 103<b> is broken. When, however, total-taking occurs the circuits from the bars 103<a>, 103<b> and 125 are completed, if the non-list switches be open, through leads 416, 417 and 418 and contacts 400, 401 and 402 which are only closed at total-taking by the rocking of the total-printing shaft. Totalprinting may also be suppressed in the usual manner by opening the main switch 237. Printing subtotals.-The usual manual resetting key 243 is shunted by lines 431 and 432 from posts 4 and 6 and by contacts 433 which are closed by the subtotal key 434. The latter also closes contacts 435, so that on depression of this subtotal key the resetting motor RM is operated by the setting up of a circuit through left-hand line 82, wire 437, contact 438, wire 439, contacts 435, lines 440, 441, subtotal relay 436, line 442, post 2, resetting-clutch magnet 233, posts 3 and 4, line 431, contacts 433, line 432, post 6 and to the right-hand line as in the machine described in Specification 216,142. Relay 436 attracts its armature and provides a short from line 437 to line 442, cutting out the subtotal key. If it be desired to print a subtotal in, say, bank 3 the resetting control contacts 128 are opened by the bell-crank 129 in the same manner as described for switches 108, 107, and 139 in Specification 190,144 and the corresponding switch 445 is closed with the supplementary lead 444 to the bar 127. Then, when the subtotal key is depressed and circuits are set up as above, resetting is prevented by the open contacts 128, but subtotal printing is permitted by a circuit through left line 82, wire 437, armature of 436, wire 441, line 446, switch 445, line 444, bar 127 of bank 3, stepped cam contacts 112, and bar 103<a> through to right side of line.

Abstract: 895,140. Electromagnets; selsyns. PER. RANTI Ltd. March 12, 1959 [March 13, 1958], No. 8023/58. Class 35. A torque motor, e.g. for servo control systems, has an unwound rotor 16 with salient poles, the extremities 17 of which are embraced by stator coils 15 large enough to permit limited angular movement of the rotor. Each stator coil is associated with, but does not necessarily embrace, a stator pole 12 ; these may be stepped as shown or may comprise steps in the stator ring (Fig. 3, not shown), and are in diametrically opposite pairs. Opposite windings are connected in series and each such pair is energized by a separate current to produce opposing torques. The pairs of poles of either the stator (as shown), or the rotor, are asymmetrically spaced, so that the rotor assumes a position dependent upon the relative current strengths, and it is arranged (e.g. by a device described in Specification 692,203) that their difference is proportional to a control signal while their sum remains constant. The rotor poles are made as long as possible, and those of the stator correspondingly short, to provide a maximum output torque.

Filed: 1923-03-26
Abstract: 212,753. Dehn, F. B., (National Pneumatic Co.). March 26, 1923. Operating doors pneumatically.- Apparatus of the kind in which variations of pressure in the fluid pressure brake system are utilized to control the movements of railway carriage doors is arranged so that the brakes can be operated to a limited extent without affecting the doors. Each car is fitted with a door control reservoir 10 fed from the. auxiliary brake reservoir 9 through a valve 12 which only allows air to pass when the pressure in the reservoir 9 is near its maximum, and also acts as a check valve to prevent air passing back into the brake system. The reservoir 10 is connected through a reducing valve 13 with a door-control valve 14 adapted in one position to put it into communication through pipes 16 with door motors 4, and in the other position to open these motors to exhaust. A pipe 26 connects the door-control valve 14 with the main brake pipe 5, and this valve is made less sensitive than the triple valve 6 for the brakes, so that putting on the brakes to a small extent does not affect the doors, but applying the brakes sufficiently to stop the train moves the valve 14 to release the doors. Figs. 4 and 5 show a fluidpressure motor for closing the doors adapted to close them slowly until the movement is almost completed when they are closed with a final " slam." In operation, fluid under pressure is admitted to a cylinder 31 through an orifice 37 and moves the pistons 33, 34 to the right, thus closing the doors, which are connected by a lug 36 to the rod 35 common to both pistons 33, 34. The air imprisoned on the right of the piston 34 escapes slowly through holes 50, 45. Near the end of the stroke, the piston 34 strikes the rod 51 of a small piston 43 and thus opens an additional exhaust port 41. This frees the final movement and allows the doors to close suddenly. The piston 43 is urged to the left by pressure fluid entering an orifice 47. A modification for use with vacuum brakes is also described.
