Respiratory apparatus to be fed with a constant flow of gas, which it then supplies to a patient, comprises an expansible and contractible reservoir 16 having an outlet valve 24 actuated by the contraction to pass gas to the patient, and a vent valve 36 opened by the inhalation of the patient and providing for the contraction of the reservoir. As shown, the apparatus also includes a gas supply from an electric turbine pump 10, a mouthpiece 40, an exhalation valve 44, and a linkage 48, 22 between the exhalation valve 44 and the outlet valve 24. The variations in the size of reservoir are effected by the movement of a diaphragm 18 to which is secured the rod 22 of the valve linkage. The arrangement of the apparatus for supplying inhaling gas is as shown. Upon exhalation, the valve 44 opens and causes the valve 24 to close and this valve 24 remains closed until inhalation causes a diaphragm 68 to open the vent valve 60 whereupon the diaphragm 18 moves to contract the reservoir and through the rod 22, to open the outlet valve 24. The apparatus is suitable to supply air or anaesthetic gas.

Filed: 1964-11-10
Abstract: 1,076,178. Seaming cans. FMC CORPORATION. Nov. 10, 1964 [Nov. 29, 1963], No. 45688/64. Headings B3J and B3K. [Also in Division B8] Apparatus for seaming the closure (C) on cylindrical or other cans (B) comprises a die (65, Fig. 6) for folding over the closure a margin (B2) of the can, which is held in a contracting collet-die (38), and a die (68) for pressing the margin (B2) against a rim (C2) on the closure, the margin (B2) being plastically stressed and stressing the rim (C2) below the rim's elastic limit so as to maintain the seal. Aluminium cans may be sealed the closures of which may be of harder metal than that of the bodies. Two or more sets of the dies are mounted in a cage (22- 26, Fig. 1) rotatable on bearings (19, 20) about a post (12) which supports a stationary cam (14) for moving the lower dies (38) towards the upper dies (65, 68) as the cage rotates. The die (38) on the left (Fig. 1) is in position to receive a can on a platform (48) which is supported on a rod (50). As the cage rotates the die (38) is raised relatively to the platform (48) and the can, the platform coming to bear against a spring washer (54) at the bottom of the cavity of die (38). The platform (48) and the can now rise with the die, compressing a spring (58) at the end of rod (50) and then collapsing the washer (54). This carries a shoulder (B1) on the can against shoulders (46, Fig. 6) on the jaws (42) of the collet-die (38), which is contracted against the surface of the can by engagement between outer surfaces (44) on the jaws and a bevel-closing ring (65) surrounding the top die. Continued upward movement of the can carries it away from the platform (54), held by compression of a further spring (61), and into engagement with the curling die (65). This die and the closing ring (65) recede, compressing springs (70, 75), as the can rises against the inner die (68). If the can and closure gauges are thicker than desired, pressure exerted by the closing die (68) will expand the jaws (42) and raise the ring (65) slightly. The die (65) assists in stripping the can from the supportng die (38).

Inventor: ROSENKRANZ HANS-GEORG
IPC: C07C37/86
Filed: 1965-10-29
Abstract: p-Cresol is separated from cresol mixtures by treating the mixtures with aqueous oxalic acid while subjecting them to azeotropic distillation until the water content has fallen to 0.5-1.8 mols. per mol. of p-cresol.  The treatment results in the formation of the semi-ester of p-cresol and oxalic acid, which is separated from the mixture and then decomposed by treatment with water.  Both the esterification and the decomposition may be effected in an organic solvent, e.g. benzene or benzine. Examples are given.

Abstract: 1281269 Control of DC motors TEXACO DEVELOPMENT CORP 29 Sept 1970 46221/70 Heading H2J A motor M driving a potentiometer P is selectively controlled by a signal at either of two frequencies (e.g. 400 Hz or 800 Hz) by a system which includes a band pass filter for each frequency, L1, C1 and L2, C2, connected to respective emitter follower amplifiers QA, QE which are followed by differential amplifiers QB, QC, QD and QF, QG, QH whose outputs are connected to a motor control circuit. The motor control circuit comprises further transistors, the arrangement being that an output from the 400 Hz channel causes Q1, Q2, Q3 to conduct and so energize the motor from the signal supply terminal 10 in one direction, while an 800 Hz signal causes conduction of Q4, Q5, Q6 so that the motor is energized in the reverse direction. The coupling of the transistors is such that if both signals appear together the transistors are biased off, thereby protecting them. The system is located at the bottom of a deep borehole, for remote control from the surface by cable, and the potentiometer adjusts the output of an amplifier connected to a detector, e.g. of gamma rays or neutrons.
