Filed: 1921-03-12
Abstract: 174,659. Bossini, R. F. March 12, 1921. Ball and float valves.-A hydraulic air compressor comprises a water outlet valve of large area which is opened by a float-actuated rod the force of which is sufficient to lift a small central portion of the valve and thereby balance the pressure on the remainder and allow it to rise; the valve is held open until the discharge of water is completed by a float-actuated pawl. Fig. 1 shows' a tank D which is alternately and automatically filled with air and water respectively, the water driving the air under pressure through a valve T into a reservoir. The water on rising to its highest position lifts a float P the lever of which closes the water inlet A and lifts a rod T<2> by which the outlet valve M, N, O, Fig. 2, is raised. The rod carries a rack V engaging a pawl Q which is raised by a float C; the discharge valve is thus held open until the level falls below the point at which the float C is upheld, whereupon the water outlet closes and the inlet is opened. Air is drawn in through a valve E.

Filed: 1976-06-04
Abstract: 1504482 -Photometric plasma analysis BIO/ DATA CORP 4 June 1976 23214/76 Heading G1A A platelet aggregation monitoring device comprises: means 14-20 Fig. 1 for generating a signal representing the difference in optical densities of platelet-rich 12 and platelet-poor 10 plasma samples; means 22 for multiplying the signal by a variable factor; means 25, 26, 28, 30 for automatically adjusting the factor so that an initial value of the multiplied signal is equal to a predetermined value; and means 32 for maintaining the factor constant once it has been adjusted.  The output of a variable-gain amplifier 22 and (A3) Fig. 3 (not shown), represented by AB Fig. 2, may correspond to e.g. four scale divisions on a chart recorder 24 when photo-resistors 16, 18 first begin comparing samples 10, 12. When a start switch (not shown) is closed, pulses from a clock 28 and (46) Fig. 5 (not shown) cause a gain network 30 and Fig. 4 (not shown) to step up the gain of the amplifier 22 by switching resistors (R11-R29) into a feedback network. When, as at C Fig. 2, the amplifier output reaches a value corresponding to 9 scale divisions, a comparator 26 and (A4) Fig. 5 connected to reference source  25 enables a clock inhibit circuit 32 (48) Fig. 5 to stop further changes. The system is thus standardised against the effects of diversity in the samples taken from different patients, the gain remaining constant until the system is reset by the start switch to deal with the next samples. At point D Fig. 2, when adenosine diphosphate is added to the platelet-rich sample, the optical density follows a characteristic pattern illustrated by the curve D-H. Ripple due to the action of a magnetic stirrer 19 Fig. 1 may be smoothed out by switching a feedback capacitor (C5) Fig. 3 (not shown) across the amplifier 20, the capacitor having been kept appropriately charged by auxiliary means (A2) Fig. 3 when not in use, so that it does not introduce a step change into the amplifier 28 output when switched in.

Abstract: 1398939 Sleeve couplings RELIABLE ELECTRIC CO 16 May 1973 [16 Aug 1972] 23274/73 Heading H2E To connect two bare or insulated wires 50, 52, soft metal channel 10 with toothed inturned flanges 12, 14, containing a slightly shorter resilient metal unflanged channel 16 carrying spikes 28 over its inner surfaces, the whole being wrapped in adherent insulating tape. U-shaped piece 30 with toothed edges 43, is crimped over the wires laid along the channels. The tape pieces are optionally cut in the crimping operation from ladder-like pre-perforated continuous strip carrying the channels. To make a tapping connection, the tapped wire 50 is laid straight while tapping wire 52 changes sides near the mid point of length to position 54. On crimping, optionally by a device described but not claimed (Figs. 1, 2, 3, not shown) and also described in Specification 1,366,626, base 18 and sides 22 of channel 16 wrap round the conductors, allowing spikes 28 to penetrate the insulation, with soft outer channel 10 lying outside the turn of channel 16. The overhanging edges 40 of tape 30 turn inwards inside channel (16, see Fig. 9) where the conductors lie together, and (see (Fig. 10) where they lie on opposite sides of the channel. The teeth 43 of the tape edge under the upper conductor in Fig. 9, and under the lower conductor in Fig. 10, can never completely prevent spikes 28 from penetrating any of the respective conductors, unlike a plain tape edge. Where the lower conductor crosses over, teeth 15 on the edge of outer channel 10 allow the conductor to pass without interference with the crimping action. In the course of the crimping process one end of tapping wire 52 is cut short.

Title: Utilization of by-products from manufacture of 2,5-dimethyl-piperazine
Inventor: IANO JOSEPH JOSEPH SCIGL
IPC: C07D295/023
Filed: 1957-07-24
Abstract: In the manufacture of 2.5-dimethyl-piperazines by heating isopropanolamine with an hydrogenation catalyst, the 2.5-dimethyl-piperazines are separated from the higher boiling material which is heated with a hydrogenation catalyst at a temperature in the range 130-300 DEG  C. to give at least one of the compounds 2.5-dimethyl-pyrazine and 2.5-dimethyl-piperazines. The relative yields of 2.5-dimethylpyrazine and 2.5-dimethyl-piperazines is dependent partly on the hydrogenation catalyst used.  For example, copper chromite, copper powder and the less active nickel catalysts favour the formation of 2.5-dimethyl-pyrazine whereas the more active nickel catalysts, e.g. Raney nickel and the finely-divided nickel formed by the reduction of precipitated nickel hydroxide, favour the formation of cis- and trans-2.5-dimethyl-piperazines.  If some of the by-product material is mixed with isopropanolamine and heated with an hydrogenation catalyst to a temperature in the range 130-300 DEG  C. less of the by-product material is formed than when the isopropanolamine is used alone.  The high-boiling by-product material may be heated at atmospheric or superatmospheric pressure and preferably 5 to 15 per cent of catalyst is used based on the combined weight of the catalyst and by-product material. The process may be carried out continuously by recycling the higher boiling by-products but advantageously from one quarter to half of the high boiling by-product is withdrawn from the system and may be treated separately.  In the examples: (a) a high-boiling fraction of the residue obtained after separating 2.5-dimethyl-piperazines from a mixture obtained by heating isopropanolamine with a hydrogenation catalyst is heated at 200 DEG  C. under pressure with Raney nickel to give 2.5-dimethyl-pyrazine and 2.5-dimethyl-piperazines; (b) a mixture of isopropanolamine, a high-boiling residue from a previous reaction and Raney nickel is heated to 200 DEG  C. to give 2.5-dimethyl-piperazines with very little high-boiling residue; (c) a higher-boiling fraction from a previous reaction, isopropanolamine and reduced nickel hydroxide are heated to 200 DEG  C. to give 2.5-dimethyl-pyrazine, and 2.5-dimethyl-piperazines with a very little high-boiling residue; (d) isopropanolamine, a high-boiling residue from a previous reaction, and copper powder are heated to 200 DEG  C. to give 2.5-dimethyl-pyrazine and 2.5-dimethyl-piperazines with very little higher boiling residue; (e) isopropanolamine, a high-boiling residue from a previous reaction and a supported nickel catalyst are heated to 200 DEG  C. to give 2.5-dimethyl-pyrazine, 2.5-dimethyl-piperazines and a small amount of high-boiling residue; (f) isopropanolamine, a high-boiling residue from a previous reaction and Raney nicel are heated to 200 DEG  C. to give mainly 2.5-dimethylpiperazines; and (g) the process of (f) is carried out continuously at 195-205 DEG  C. to give mainly 2.5-dimethylpiperazines.
