Title: Cabin pressure regulator
IPC: G05D16/00
Filed: 1967-06-26
Abstract: 1,128,936. Pressurizing aircraft. UNITED AIRCRAFT CORP. 26 June, 1967 [11 July, 1966], No. 29415/67. Heading F4V. [Also in Division G1] The air pressure inside an aircraft cabin is automatically regulated by an electric control system fed with signals representing the measured pressures inside and outside the cabin, and the predetermined values of the pressures corresponding to the take-off, cruising and landing altitudes of a particular flight plan, the system maintaining the maximum permitted difference between the internal and external pressures, limiting the rate of change of internal pressure to one which will not prove uncomfortable to the passengers, and ensuring that the internal cabin pressure is equal to the external pressure at landing. The circuit regulates the cabin pressure in three modes, namely ascent, cruising and descent, the changeovers being effected automatically. The predetermined values of ambient pressure at the cruising altitude P acr  and at the landing altititude P al  are set up initially on non-linear potentiometers, and modified in accordance with the barometric variations in ambient pressure. These signals are individually fed to function generators 404, 408 respectively (Fig. 6), together with the measured ambient pressure signal P a  to provide a control signal P d , the circuit selecting the appropriate calculating network consistent with the particular mode of the flight plan, ascent, cruising or descent. The selection is controlled by (a) a number of wheel switches, operated when the aircraft is on land, (b) a cruise relay 452, operated when the ambient pressure P a  is substantially equal to the predetermined cruise pressure P acr , (c) a descent relay 428, energized with cruising relay 452, but remaining closed when 452 subsequently opens. The cabin pressure control signal P d  is compared with the measured cabin pressure signal P c  (Fig. 5) in a comparator 524, and the amplified error signal # energizes a motor 534 to control an out flow valve 540 which adjusts the internal cabin pressure to eliminate the error signal. Circuit 458 ensures that the difference between the external and internal cabin pressures does not exceed the permitted maximum, and circuit 502 limits the rate of change of cabin pressure. The control system incoporates facilities for coping with modifications to the scheduled flight plan during flight.

Title: Method of treating brewing yeast
IPC: C12N1/00
Filed: 1929-09-30
Abstract: 320,021. Marescu, N. Sept. 28, 1928, [Convention date]. Yeast.-Yeast from fermenting vats is made suitable for baking purposes by treating it in succession with such acids and alkalis as will form a salt which will maintain or even strengthen the vital functions of the yeast, particularly with phosphoric acid and subsequent neutralization with ammonia resulting in the production of ammonium phosphate which can nourish the yeast. The yeast is then washed with water, ammonium carbonate solution, and again with water preferably with the addition of a small amount of ammonium phosphate. To give the finally washed yeast good keeping properties it is found desirable to acidify strongly the last washing water with acetic acid and to free the yeast from this acid solution by pressing when it is ready for sale.

Abstract: 675,083. Printing processes. NATIONAL CASH REGISTER CO. Dec. 4, 1950 [Dec. 9, 1949], No. 29613/50. Addition to 666,438. Class 100 (ii). [Also in Group XV] The production of accurately aligned duplicate printed matter is effected by assembling a stack of superimposed sheets, each of which, as described in the parent Specification, is coated on its rear surface with a film including a profusion of minute liquid droplets containing an adsorbate substance and on its front surface with a coating of absorbate substance which on contact with the adsorbate substance causes a colour change on the latter, so that the absorbate and adsorbate surfaces of adjacent sheets are in contact, placing the stack in a printing press and operating the press so that absorbate film is ruptured locally under the pressure of the type to express the adsorbate on to the adsorbent surface thereby producing local coloration in the latter. Fig. 1 shows a two-page folded assembly with the corner of the first page turned back to show alignment of printed matter an( later applied writ ten matter. Fig. 3 shows an accordion folded assembly of three sheets. Fig. 4 shows four sheets secured marginally by staples. Storage of the printed folders between the time of printing and use, in such a manner that no absorbate surface is in contact with an adsorbate surface, is obtained, as shown in Fig. 5, by placing the folded sheets one inside the other with an insulating sheet 50 separating the facing surfaces of the innermost sheets.

Pulpwood, i.e. logs of wood for conversion to wood pulp, is fed to defibrer magazines 11 from a debarking unit by a feed conveyer 1 to the lower strand 3 of a horizontal conveyer 2 where it is pushed by pushers 5 along a guide frame 6 having outlets 7 each of which is controlled by a gate 8. A dog 32 of a selector 22 (Fig. 3) is driven through a friction clutch by an electric motor (not shown) to contact a core 33 to close the circuit of an electromagnet 35 in an electropneumatic valve 24 to lift a needle 36 and cause a piston 43 to move to open gate 8 of the first outlet 7. Pulpwood is delivered into the first magazine 11 and builds up on the left hand side until it actuates a sensor 21 which causes a plate 16 to move to the right to close the left-hand part of the entrance to the hopper. Pulpwood builds up on the right-hand side until it causes the right-hand sensor 21 to operate which effects closing of the gate 8 and opening of the next gate 8. Jamming of pulpwood in a gate is prevented by a sensor (Fig. 5, not shown). Excess pulpwood is passed to the upper strand of the conveyer 2 by a device 18, 19. When pulpwood is on the upper strand it operates a switch 31 to switch off the feed conveyer 1. Pulpwood on the upper strand of the conveyer 2 is fed back to the lower strand through an opening 79.

Filed: 1920-10-21
Abstract: 172,485. Jardine, Sir E., Watchorn, E., and Swindall, J. W. Oct. 21, 1920 No Patent granted (Sealing fee not paid). Lace machines.-To assist the operation of putting-up fresh sets of warp threads, the guidebars A of twist-lace machines, particularly plainnet machines, are mounted on arms H carried on the inner ends B<2> of a number of levers B looselv disposed on longitudinal shafts C at the front or rear of the machine. The guide-bars can be raised out of the normal working position determined by stops R by turning screws E mounted in bearings D<1> of fixed brackets D, the screws turning in nuts F the projections F<1> of which engage recesses in the outer ends B<1> of the levers B. The front and rear guide-bars are thus raised until the guides 0 project above the combs Q. The guide-bars also open out or separate when in the raised position, the operation of putting-up warp threads being thus facilitated. The guide-bars are pivoted for freedom of longitudinal movement to parallel arms H mounted on axles on the inner ends B<2> of the supporting levers B. The bars are connected to the cam levers at one end and to the springs at the other end by means of flexible connections such as stranded wire cables J which are hooked on to adjustable draw-bars M which carry coil springs N disposed between adjusting-nuts M<1> and a cross-head L. The springs N are simultaneously released by slackening a screw K carrying a hand-wheel K<1> and passing through the crosshead L, the strain being thus taken off the guidebars A which can then be raised without difficulty. When the guide-bars are lowered again into working position the original compression is restored without trial by tightening up the screw K until a stop collar K<2> comes in contact with the frame &c.
