Title: Improvements in or relating to preserving oxidizable hydrocarbons
IPC: C08K5/29
Filed: 1930-04-29
Abstract: The ageing of oxidizable hydrocarbons, e.g. rubber and oils, is retarded by the addition of a naphthyl formamidine of general formula R-N=CH-NH-R1 (where R1 and R represent naphthyl groups), produced by reaction between a naphthylamine and formic acid.  Specified compounds are di-a -naphthyl formamidine and di-b  naphthyl formamidine.  Example: Equi-molecular amounts of a -naphthylamine and formic acid are mixed in a sufficient quantity of aniline and refluxed for 4-6 hours, the water formed in the reaction being allowed to escape.  The temperature is then raised to drive off any remaining volatile liquids and the residue is crystallized from alcohol.ALSO:The ageing of oxidizable hydrocarbons, e.g. rubber and oils is retarded by the addition of a naphthyl formamidine of the general formula R-N = CH-NH-R1 (where R, and R1 represent naphthyl groups), produced by reaction between a naphthylamine and formic acid.

The tray is on a support 29 which is perforated front and rear. All air which enters the cabinet is blown by a blower 25 through an exhaust plenum 21 and exhaust filter 17. Make-up air is supplied to the work chamber 45 by a blower 20 via a filter 35, the filtered air being in laminar flow. Air also enters the cabinet through the access port 14. Motors which drive the blowers 25 and 20 are so powered that (a) the quantity of air passing through the access port 14 is equal to or greater than the quantity of filtered make-up air and (b) the access air velocity is at least double the make-up air velocity whereby contaminated air over the work tray is inhibited from passage outwardly through the access port. There is no recirculation of air in the cabinet. Air flow rates within the apparatus may be monitored by an anemometer or pitot tube. The air which leaves the exhaust filter may pass through charcoal, chemical scrubbers and air incinerators. The cabinet may be constructed from stainless steel, fibreglass or polypropylene. A connection between the motors driving the exhaust and make-up air blowers 25 and 20 is such that in the event of the failure or reduction in speed of the exhaust motor relative to the make-up air motor an alarm is sounded and the entire unit is shut down for decontamination.

Title: Electric resonators for ultra-high frequencies
IPC: H01P7/06
Filed: 1946-05-03
Abstract: 611,667. Electric resonators. STANDARD TELEPHONES & CABLES, Ltd. May 3, 1946, No. 13523. Convention date, Feb. 22, 1944. [Class 40 (viii)] In a cylindrical cavity resonator the height h is adjusted simultaneously with the turning plunger 2, so that when the cylinder is tuned to Eo waves of the required frequency, which depends on the diameter D but not on the height h, it shall not resonate to undesired H1 waves, whose frequency depends on the height h, while the excess-voltage factor Q is prevented from decreasing with frequency. Thus the bottom 3, Fig. 2, of the cylinder may be adjusted simultaneously with the tuning plunger 2, or a partition 3a, Fig. 3, may be moved so..as to vary the exposed length a of the plunger while it simultaneously varies the height h. Mechanical details of this embodiment are given in Fig. 4 (not shown).

IPC: B27G11/00
Filed: 1957-04-29
Abstract: <PICT:0840510/III/1> In a machine for cutting packs of veneers 3, glue is applied to the cut surface 3 of the veneer pack by a constantly driven roller 9 that extends parallel to the knife 5, is arranged for up-anddown movement in the machine frame, and is controlled by guideways arranged beside its path, so that it approaches the cut surface C on being lowered from its uppermost, rest position, shown in solid lines, rolls along the cut surface from top to bottom, and is lifted away from the cut surface at the beginning of the return movement.  The roller 9 receives glue from a reservoir formed in the nip between it and roller 10.  Rollers 9 and 10 are mounted between two arms 11 suspended from a shaft 12 which is constrained to follow the elongated path B by reason of driven pinions at its ends being held in contact with an elongated, vertical, toothed cam.  The lower parts of arms 11, and hence rollers 9 and 10, are caused to follow the desired path by pulleys 19 and 21 mounted on arms 11 to engage resiliently fixed guide bars 20. Cutting bar 7 and shoot 8 are moved out of the way of roller 9, and subsequently returned to position, by means including an electromagnet controlled by switches actuated by the movement of the cutting knife and glue roller carrier.  Similar means control the starting and stopping of an electric motor driving the pinions on shaft 12.  Air from nozzles 24 removes dust from the cut surface before glue is applied.

Abstract: 1351355 Automatic speed control INTERNATIONAL BUSINESS MACHINES CORP 7 May 1971 [27 May 1970] 13615/71 Heading G3R The acceleration of a D.C. motor 10 e.g. driving a carriage in a printer is controlled through a bistable latch 21, which energizes the motor for main periods equal to the difference between the time interval of actual speed pulses from a generator 12 and the time interval of reference pulses from a single shot device 24, each reference pulse interval being initiated by a speed pulse, the motor also being energized for additional time periods which are dependent on the main periods. The speed pulses from generator 12 are fed through pulse former 22 into latch 21, which has a feedback loop to single shot 24, and directly into single shot 24 which emits a reference pulse after a reference time interval e.g. 250 ÁS, the pulse from single shot 24 turning latch 21 on, the next speed pulse turning it off. Thus the motor is periodically energized until the speed pulse interval equals the reference time interval. If the motor runs at overspeed, no pulses are applied to latch 21 from single shot 24, which is reset by feedback (from latch 21 into B1) before the reference time interval has elapsed, the motor is not energized and thus slows down. For a faster response, latch 21 is fed into a proportional single shot 26 which energizes the motor for additional periods proportional to the length of pulse emitted from latch 21. A starting pulse is obtained from single shot device 20. Pulse generator 12 may be magnetic, optical, capacitative or inductive.
