[Also in Division B3] The torques transmitted by the work rods of a rolling mill are measured by strain gauge bridges and lubrication between the rolls and the workpiece is adjusted to reduce the difference in torque to zero, thereby improving the quality of the strip fed through the mill. As shown (Complete Figure), a rolling mill stand 3 comprises two work rolls 1, 2 driven by a motor 4 through gears 5 and driving spindles 6, 6A. Each spindle carries four resistance-wire strain gauges 17, 18, 19, 20 (Fig. 1) connected into a D.C. bridge (Fig. 2) whose output signal is used to control the frequency of interruption of a radio frequency oscillator feeding an aerial 24. The above apparatus is mounted in a transmitter unit 23 carried by the drive spindle 16. The radio frequency signal is picked up by a receiving aerial 25, reconverted to a D.C. signal at 26, and fed to a differential microammeter 7 together with a torque signal derived in analagous manner from the other drive spindle 16A, whereby meter 7 indicates the difference in torques. The meter reading is used to control, manually or automatically, two valves 12, 13, controlling the supply of roll lubricant to the rolls 1, 2. The transmitter 23 is powered from a unit 27, also carried by the spindle, having batteries 42, 49 whose circuits are selectively opened or closed by a signal of characteristic frequency transmitted by oscillator 30 and received via aerials 29, 28 to operate a control relay, through a resonant circuit tuned to the frequency. A signal of a different frequency from oscillator 31 may be transmitted to cause a further control relay to add a predetermined unbalance to one of the strain gauge bridges, to check the calibration. In a modification the transmitters 23 are powered through slip rings from a stationary battery.

Title: Method of and device for producing patterning or fancy effects on yarn
IPC: D01H5/36
Filed: 1937-07-13
Abstract: 498,684. Producing patterned yarns. HAMEL, E. July 13, 1937, No. 19387. [Class 120 (ii)] Pattern or fancy effects are produced on yarns by imparting a varying retardation or acceleration to the means, for example a cam and lever system, which variably operates the pattern-thread guide, for example, a knopping-plate, by introducing a disturbing element in the driving-train, whereby uneven spacing of the effects is ensured and grouping in the fabric is avoided. The cam 8, which controls the movement of the knopping or guide plate 1, is eccentrically mounted on a rotary support, or it may be irregularly driven through a clutch, and the delivery rollers of the patterning thread may also be irregularly driven through a clutch. As shown in Fig. 2, the cam is mounted on a pin 17 eccentrically mounted on a driving-shaft 18 eccentrically mounted in a sleeve 21 rotated by a chain drive 25 in a bearing 24. In the arrangement shown in Fig. 6, the cam 8 is driven through a clutch 28, the clutch lever 29 being operated by an endless chain 32 carrying cam elements and driven intermittently and preferably in irregular steps. A clutch 36 may be provided and operated by a lever 34 and link from the lever 29 so as to control the delivery rollers 38, 39.

Title: Improvements in or relating to hydraulic rams
IPC: F04F7/02
Filed: 1957-06-20
Abstract: 803,966. Hydraulic rams. YAMAGUCHI, T. June 20, 1957 [Aug. 2, 1956], No. 19477/57. Class 102(2). [Also in Group XXIX] A hydraulic ram is provided with a check valve comprising a ball valve member 7 in the form of a bladder of flexible material filled with a light gas, e.g., hydrogen. When the flow of water through the inlet chamber 3 reaches a critical velocity the waste valve 6 closes and the water pressure moves the ball 7 away from its seating 9 to allow water to flow into the air chamber 8 compressing the air trapped therein. The sudden decrease in pressure draws the ball member 7 onto its seat 9 and the water in the chamber 8 is expelled by the compressed air until it reaches a desired level, e.g., M when the air is allowed to escape through an inverted cup 14 to a pipe 15 to aerate and increase the lift in the rising column of water. Valve member 5 opens due to the reduction of pressure in the inlet chamber 3 whereby a quantity of air is drawn into the chamber 3 and collects under the valve member 7 in readiness for the next cycle of operations. By varying the position of the stop member 17 the cyclic period is varied and the quantity of air sucked into the inlet chamber is varied by the water level in the penstock 10.

Title: Improvements in or relating to the electrical depositing of chromium
IPC: C25D5/02
Filed: 1927-07-23
Abstract: 275,223. Siemens & Halske Akt.-Ges., (Assignees of Fink, C. G.). July 27, 1926, [Convention date]. Chromium and other metals, depositing; cells; electrodes; electrolytes, circulating.-In electroplating objects with chromium, current is passed from an anode to a portion only of the object at a time, other parts being meanwhile protected from oxidation by exposure to the electrolyte or hydrogen or both. In an example a cylinder to be plated on the outside is partiallv immersed in the electrolyte above an anode of limited extent. The cell is surmounted by a hood, and electrolyte is distributed over the unimmersed portion of the cylinder from a rose. In coating a cylinder inside, it is mounted upright and fitted at the base with a cap so as to form a cell, and at the top with an extension. The level of electrolyte is preferably above the upper end of the cylinder. The anode consists of a horizontal ring. the height of which is adjustable; plating is preferably commenced from the top. The level of electrolyte is lowered as the anode is lowered. A tube to be plated internally is provided with cord rings 20 ,22, Fig. 4, the anode being mounted on a glass plate 29 surmounting a piston 28 ; in this case, plating is begun from the bottom. A large sheet to be plated is mounted vertically in a cell half-immersed and after plating of one half is quickly inverted. Electrolyte is distributed over the upper half from a perforated pipe. The invention is particularly applicable to the plating of cast-iron in which the conductive characteristics vary, owing to a honeycombed structure beneath the surface. The electrolyte may consist of chromic acid together with sulphuric acid or a sulphate. The current density may be ¢-1¢ amps. per sq. in. According to the Specification as open to inspection under Sect. 91 (3) (a) metals other than chromium may be deposited by the process. This subject-matter does not appear in the Specification as accepted.

Title: Process and apparatus for driving internal combustion engines with solid pulverised fuel
IPC: F02B45/02
Filed: 1924-08-19
Abstract: 236,756. Pawlikowski, R. Aug. 19, 1924. Regulating; valves.-In an engine supplied with powdered fuel mixed with a little air under pressure, a stream of the mixture preferably passing the admission valve: oil is also supplied to the engine to start ignition, but the engine may work exclusively with either fuel. Fig. 1 shows the invention applied to a four-stroke engine. Coal from a hopper 7 is ground in a mill 8 and conveyed by a fan 9 to a hopper 5. From the hopper, the fuel and air are circulated by worms 26 past the fuel-admission valves 32, 33, which admit the fuel in quantities controlled by the governor to a chamber 3, while the pressure in the cylinder is low, whence it is blown by air entering' the valve 42 into the cylinder. Oil is supplied to a cup 51 below the chamber 3 and is ignited by the heat of compression. The fuel-admission valves are formed as shown in Fig. 3. The face of the valve 33 is like a knifeedge; on its rising, the interior of the cylinder is put into communication with the exhaust pipe through ports 38 and its hollow stem 39 in order that it may be swept free from dust. As it continues to rise, the ports 38 are closed and the valve 32 is lifted by it; the ports 38 are agam opened before the valve 33 closes. The lift of this valve is controlled by the governor through the shifting fulcrum 48 of the valve lever. Fig. 8 shows an air compressor K driven by an electric motor M, coal-grinding mill 8, and a mixer comprising a cylinder 71 to which air from a passage 80 and dust from a hopper 63 are admitted by valves 32, 33 as described above. The mixture may be expelled by a plunger 73 or by the air pressure alone to pipes 75a, 75b leading to several cylinders 2. The high-pressure air acting upon pistons R, R<1> controls respectively a wedge 70 for limiting the lift of the valve 32, and a valve 102 at the inlet of the pump K.
