Title: Improvements in the control of electrical spot welding
IPC: B23K11/11
Filed: 1970-04-13
Abstract: 1301149 Welding by pressure KRONPRINZ AG 13 April 1970 [14 April 1969] 17410/70 Heading B3R A method of checking the quality of spot welds is based upon measurements, taken after switching off the supply of welding current, of the movement of the electrodes towards each other i.e. measurements indicating the contraction of the workpieces due to cooling. The resulting values are compared with limiting values previously ascertained between which satisfactory welds were produced. Means may be provided to give a signal indicating a faulty weld if the measured value falls outside the limits set. The method may be applied where continuous or intermittent pulse welding current is used.

Title: Arrangement for stopping and starting a loom provided with automatic shuttle-changing means
IPC: D03D45/34
Filed: 1951-07-25
Abstract: 704,694. Loom stopping during shuttle changing. S.O.M.I.M. SOC DE MONTAGE POUR L'INDUSTRIE MECANIQUE. July 25. 1951 [Aug. 3, 1950], No. 17697/51. Class 142(2) Upon near-exhaustion of a cop, a weft feeler (not shown) raises an arm 11, Fig. 1, to release a plunger 14 which lifts an arm 8 through a rod 17. The arm 8 is continually oscillated while the loom is running by a cam 2, and when raised its, hook 9 engages a pin 18 to lock brake shoes 23 against. a, drum 26 forming part of a differential gear system. The drum 26 is normally rotated by a. continually revolving spur wheel 28 having an extensiom 29 carrying teeth 31 engaging the differential pinion 32. When the drum 26 is locked, pinions 32, 33 drive a gear 36 fast with a shaft 27 carrying cams 45, 46 for operating the shuttle-changing mechanism (not shown), and a cam 30 for stopping and restarting the loom. The loom starting and stopping mechanism (not shown) is connected to an arm 39 carrying a roller 38 running in the. groove of the cam 30. When the loom is running, the roller 38 lies in a recess 40 in this groove, but movement of the shaft 27 shifts it to the main track, moving the lever 39 to stop the loom. When the shaft 27 has almost completed one revolution, a pin 51 on the gear 36 engages a lever system 53, 55, 56, to depress the arm 8 and pull the hook 9 clear of the pin 18 and release the drum 26. A portion 48 of the cam groove, returns the roller 38 to the recess 40 to restart the loom. The shaft 27 is held stationary during normal weaving by a spring-pressed roller entering a notch in the gear 36 (not shown). The lever 39 may be hand-operated to reverse the loom. The dropping of the arm 8 resets the weft feeler device.

Title: Improvements in or relating to the catalytic processing of hydrocarbons
IPC: B01J27/06
Filed: 1943-10-27
Abstract: In catalytic processes for the treatment of hydrocarbons, such as polymerization, alkylation and isomerization processes, wherein volatilizable halide catalysts of limited solubility in the reaction products are employed, a cooling fluid is injected into the vaporous reaction products before their condensation in an amount sufficient to reduce the temperature to the dew-point. When the mixture reaches the condenser, sufficient liquid is present to dissolve any catalyst which may condense.  The cooling fluid may be the liquid product of the reaction or a gas or vapour, and may be introduced continuously or intermittently.  In the isomerization of normal paraffins with aluminium chloride and hydrogen chloride, part of the condensed reaction products from the condenser are fed back to a point just ahead of the same in an amount of from about 5 gals. per 100 gals. of reaction product, where the reactor outlet temperature is 200 DEG F., to about 60 gals. where the temperature is 340 DEG  F., using a pressure of about 200 lbs./sq. in.  The amount varies directly with the temperature and inversely with the pressure.

According to the construction shown in Fig. 1, combustible mixture, or air, is compressed in the crank casing and is transferred to the combustion space through ports g, the exhaust ports b being controlled by an auxiliary piston h connected to an eccentric on the crank shaft. To vary the moment at which the charge from the crank case enters, or is cut off from, the combustion space, a sliding ring-valve, actuated by cams or eccentrics,. is mounted in the annular transfer passage e. The functions of the ports b, g may be interchanged, in which case the exhaust ports adjacent to the crank end of the cylinder may be controlled by a. rotary or oscillating valve in the exhaust pipe. Modified constructions of engines are described, in which the diameter of the auxiliary piston is greater than that of the main position, and in which additional ports for the admission of scavenging air are located adjacent the inlet ports for combustible mixture. The additional ports are controlled by an extension of the main or auxiliary piston. A sparking-plug may be mounted in theauxiliary piston.
