Patent GB-405980-A (GB)
Title: Improvements relating to the injection of fuel to the cylinders of internal combustion engines
IPC: F02M59/10
Filed: 1932-07-12
Abstract: 405,980. Fuel injectors. MILLAR, W. H., 19, Sandford Avenue, Bloomfield, Belfast. July 12, 1932, No. 19660. [Class 7 (iii).] An improved fuel injector is actuated by the cylinder pressure on a piston 14 which is controlled by a spring 15 (Fig. 1). Integral with the piston 14 is a combined nozzle and plunger 18 which works in a rotatable sleeve 19 which has suction ports 20 communicating with a suction space 21 and a fuel chamber 22. The plunger has two helical ledges 18a at its upper end that, when the piston is forced upward by the cylinder pressure, cover the ports 20 and trap a measured quantity of fuel in the chamber 22, the amount of which is regulated by the angular position of the sleeve. The fuel is held under pressure until a timing valve 25 operated by a cam 35 uncovers the ports 27 and admits the fuel to the nozzle orifice 23, 23a, and to the cylinder. At the end of the injection period the timing valve 25 rises to withdraw residual fuel from the nozzle and prevent dribble. In a modified construction the actuating piston is external to the cylinder but connected thereto by a pipe and an annular passage around the nozzle. In another modification (Fig. 5), the fuel is measured by adjusting the axial position of an opposed plunger 74 under the control of a spring 75 and balanced by a second piston 83 connected to the cylinder. In this case the timing valve is kept stationary but is axially adjustable by hand and the movement of the actuating piston automatically times the injection.

Title: Improvements in or relating to cereal composition for moist batters and dough and method of making same
Inventor: HARREL CHASTAIN G
IPC: A21D13/06
Filed: 1955-07-11
Abstract: In making batters and doughs which may be stored, e.g. at 35-50 DEG F., without viscosity decrease as a result of "thinning" of the starch, the ordinary flow is replaced wholly or partly by an intimate admixture of dry, discrete, wheat starch particles free from diastatic enzymes, small and broken starch cells and mould spores, and a small proportion of dry, discrete, undenatured gluten particles also free from diastatic enzymes and mould spores.  The batter or dough may be packaged under partial vacuum. According to examples, a griddle cake better contains 66 per cent of the wheat starch-gluten mixture, with non-fat solids of milk, shortening, salt, baking powder, dried whole egg and an emulsifier, and a biscuit dough contains 18.5 per cent of the wheat starch-gluten mixture, and 55 per cent of wheat flour, with shortening, non-fat solids of milk, baking powder and salt.

Title: Singeing and warping machines
IPC: D02J3/16
Filed: 1929-06-29
Abstract: 335,916. Triggs, W. W., (Standard- Coosa-Thatcher Co.). June 29, 1929. Stop-motions.-In a, combined singeing and warping machine, an electric stop-motion is operated and the burners turned off when the yarn breaks or when a measured length of yarn has passed through the machine. On breakage of a yarn, a detector completes a circuit which operates a mercury switch, and causes a relay to disconnect the mains supply. This stops the motor, and de-energizes an electromagnet which controls a. latch holding the bracket 62 against the tension of the chain 63; thus the weight 65 causes the lever 61 to rotate. The lever, through a series of links, rotates the burners to an inoperative, position. The circuit to the mercury switch is also completed, and the stop-motion operated when a given length of yarn has passed through an attached measuring machine, or when a switch is closed manually.

Abstract: 963,094. Ophthalmometers. SOC. ANON. GUILBERT ROUTIT & CIE. May 21, 1963 [May 22, 1962], No. 20221/63. Heading G2J. An ophthalmometer of the kind having two sighting marks which are projected on to the cornea of an eye under examination so as to form by reflection at the cornea images for observation through an eyepiece and having a beam splitting and beam combining system for duplicating the image of each sighting mark, is characterized by means for selectively rendering one or other of the sighting marks inoperative and control means adapted to enable the two images of the operative sighting mark to be linked to give the specific radius of curvature of the cornea at a particular point. Light from lamps 1a, 1b is projected through sighting marks A, B on to the cornea of the eye under test, and is reflected thereby through the objective 3 on to a beam splitting and beam combining arrangement of prisms 5, 6 whereby two images of each sighting mark are formed for viewing in an eye piece 13. Each sighting mark comprises a male and a female section so that the two images of one mark may be linked when the second mark is inoperative. The images are brought into coincidence by moving the mirrors 7, 8. The apparatus shown in Fig. 10 may be used in conjunction with the ophthalmometer to measure the radius of curvature of other surfaces, e.g. a lens. The lens is held, by suction, in the cup 45 which is rotatable about a horizontal axis to bring different points on the surface of the lens under examination, the angle of rotation being recorded by the pointer 54 on the scale 55. A mirror 56, inclined at 45 degrees to the horizontal, directs light rays from the surface of the lens to the ophthalmometer.

Filed: 1929-07-03
Abstract: 335,935. Standard Telephones & Cables, Ltd., and Blumlein, A. D. July 3, 1929. Simultaneous telegraphy and telephony.-In a composite system in which the circuit is alternately arranged for speech transmission in one or other direction only, the telegraph facilities. operate only in the same direction as the telephone transmission, i.e. East-West telegraphy proceeds only during East-West periods of conversion. All frequencies below the speech band may be used for telegraph transmission and arrangements can be made to retransmit the last part of a message cut off in transmission when the transmission conditions are again set up. For those telegraph systems in which the receiver must be running a preliminary series of impulses may be sent to start the receiver. The Figure gives a schematic representation of the apparatus at one end of a cable, that at the other end being similar. The apparatus is set for receiving signals, telephone signals passing through filter VF and amplifier RA and telegraph signals through filter TF to TR. Detector RD enables PR to pull up when signals are being received to short MSR. When speech currents are to be transmitted they pass through amplifier TA to delay network DN and also to detector TD allowing MSR to pull up connecting the cable to DN and also connecting the telegraph transmitter TT to cable. The devices TS and RS stop and step back the telegraph transmitter and receiver respectively when the relay MSR pulls up and releases.
