Title: Improvements in the manufacture and production of methyl chloride
IPC: C07C17/16
Filed: 1933-10-21
Abstract: Methyl chloride is made by heating methanol and hydrogen chloride to 100--200 DEG  C., in a body of zinc chloride solution, the methanol being in excess.  The zinc chloride solution may be of 45--75 per cent strength.  The methanol may be caused to dissolve in the zinc chloride solution before the hydrogen chloride is introduced.  In an example a zinc chloride solution of 68 per cent is heated to 126 DEG C., and methanol is allowed to flow in through a heat-insulated inlet tube opening in the lower third of the vessel.  Hydrogen chloride is introduced through a sieve plate at the bottom crude synthetic methanol may be employed as starting material.

Abstract: 361,506. Drying-ovens. GEHNRICH OVEN CO., Inc., Skillman Avenue, Long Island City, New York, U.S.A.-(Assignees of Gehnrich, C. L. ; Elmhurst, New York, U.S.A.) Sept. 30, 1930, No. 29260. Convention date, Sept. 30, 1929. [Class 34 (ii).] An oven for baking materials, such as iapanned articles, which give off combustible vapours is provided with a damper which connects the outlet pipe from the oven with the atmosphere for a predetermined period from the commencement of the bake, until the combustible vapours have all been evolved, and then connects it to an inlet pipe to cause re-circulation of the gases through the oven. Means are also provided for switching out the electric heating elements should the exhaust draught cease from any cause. In the oven shown, gases are withdrawn through pipes 3 by a fan 4 and passed to a pipe 7 containing a pivoted damper 9 which is weighted at the inner end to set it to direct the gases to atmosphere. The outer end of the damper is connected to the plunger of a solenoid 12, in the circuit of which is a time relay 14. On closing the oven door, a switch 15 is closed which completes the circuit of the relay 14, the latter after a predetermined time causing the solenoid to be energized and so to move the damper 9 to the position shown in broken lines, in which the gases are returned to the oven. The quantity of gases re-circulated may be controlled by a damper 16 and by an adjustable screw 10 which limits the position of the damper 9 so that part of the gases are returned to atmosphere. The magnetic motor starting switch 5 is also in the circuit of the switch 15, so that the motor is started and stopped respectively when the door is closed and open. In order to switch out the heating elements when no draught is produced in the oven a safety switch 17 is operated by a vane exposed to the current in the exhaust pipe, and controls a magnetic switch 19 in the heating circuit.

Title: Improvements in pistons for high speed internal combustion engines
IPC: F02F3/22
Filed: 1950-12-05
Abstract: 690,298. Pistons. MAYBACH, K. Dec. 5, 1950 [Sept. 9, 1950], No. 29737/50. Class 122(i) In a piston 1 suitable for high speed internal combustion engines and having a crown space 2 supplied with cooling oil through a stationary tube 4 telescoping with a tube 3 secured to the piston and in communication with the space 2, and from which space oil is withdrawn through a second pair of telescoping tubes 5, 6 variations in pressure to which the cooling oil is subjected in the space 2 during piston working are compensated for by varying the volume of the space 2 by means e.g., a piston 20 in the piston head whereby the quantity of oil supplied is limited to the amount required for cooling. During the upward stroke of the piston 1 the rate of increase of effective volume of the tube 3 is greater than the rate of oil fed through a duct 9, a non-return valve 13 and the tube 4, hence pressure in the space 2 falls causing the compensating piston 20 to rise and so restore the pressure. Back-flow of oil through the discharge tubes 5, 6 is prevented by a non-return valve 14. During the downward stroke of the piston 1 the valve 13 closes and so cuts off oil-feed from the duct 9, but oil is forced from the tube 3 into the space 2 and is discharged therefrom through the tubes 5, 6 the valve 14, and a discharge duct 10. Cooling oil for other pistons in parallel is supplied and discharged through ducts 11, 12 respectively. In a modification the compensating piston is guided on a central sleeve depending from the crown of the piston and communicates with the cooling space and with the little end bearing of the connecting rod for lubrication thereof.

Abstract: 1506859 Waveform and phase changing IRD MECHANALYSIS Inc 26 Nov 1974 [30 Nov 1973] 29744/77 Divided out of 1506856 Heading H2F The invention relates to apparatus for developing synchronous sine and cosine signals from a pulse train. As shown (Fig. 4), a pulse train, developed, e.g., by a mark on a rotating body, is fed through a one-shot multivibrator 209 to form pulses A (Fig. 2) of width determined by switch 160E. These pulses control sawtooth generator 211 fed with constant current from terminal 212 to form waveform B, which is applied to a free-running multivibrator 214 to produce square pulses C. The amplitudes are made proportional to the input pulse frequency by the circuit of Fig. 3 (not shown) and fed to an integrator 84 to form triangular waveform D, which is converted in shaping circuit 85 to a sine wave K. To form the corresponding cosine wave the square wave C is fed to differentiator 218 to produce positive and negative pulses E, which are all converted at 219, 220 to positive pulses F and modified to have uniform width by one-shot multivibrator 221. These control sawtooth generator 222 to form pulses G, which produce square pulse train H from free running multivibrator 226. The frequency of pulse train H is halved at 229, 230 to form pulse train I, integrated at 92 to produce waveform J, and converted in shaping circuit 93 to sine wave L, leading by 90 degrees on sine wave K. The two sinusoidal waveforms K, L are compared in a logic circuit (Fig. 5, not shown) to ensure that they bear the correct phase relationship.
