Title: Improvements in or relating to a windshield cleaner
IPC: B60S1/38
Filed: 1948-04-26
Abstract: 675,757. Windscreen-cleaners. TRICO PRODUCTS CORPORATION. April 26, 1948 [May 12, 1947], No. 11429/48. Class 138 (i). A windscreen cleaner comprises a flexible squeegee unit conformable to the surface being wiped, a pressure distributing holder having relatively movable parts and means for attachment to an actuating arm and means whereby the squeegee unit may be connected to and disconnected from said holder by relative movement between the unit and the holder in the lengthwise direction of the unit. The squeegee unit, Fig. 1, comprising a rubber wiper 19 supported in a flexible backing strip 22 provided with clamping fingers 23 which grip both sides of the wiper, is connected to the pressure distributing holder attached to the wiper arm 2. The pressure distributing holder comprises a channelled primary yoke 5 connected at 10 to the arm 2, the ends of which primary yoke are pivotally connected at 7 to channelled secondary yokes 6. The pivotal connections 7 are nearer to the inner ends of the secondary yokes than to the outer ends but they may be connected nearer to the outer ends. The backing strip 22, Fig. 4, is provided on each side with four laterally projecting lugs 25 which pivotally and slidably engage in seats formed in the ends of the secondary yokes by underlying hooked portions 27. The open ends of the seats all face in a common direction lengthwise of the wiper. In order to maintain the squeegee unit in position the upper face of one end of the right hand secondary yoke 6, Fig. 4, is apertured to receive a pin 30 resiliently mounted on the squeegee unit. As shown in Fig. 5 the pin 30 has a head 33 confined between the backing strip 22 and the top of the rubber wiper 19. In order to disengage the squeegee unit from the holder the pin 30 is depressed and the unit is pulled to the left as indicated in Fig. 4. When replacing the squeegee unit the pin 30 is depressed, as the unit is slid to the right as indicated in Fig. 4, and snaps into the aperture in the end of the secondary yoke. The wiper 19 may be removed from the backing strip 22 by springing one of the downturned stops 34, and then withdrawing the wiper lengthwise. The wiper may also be removed by compressing it sufficiently so that one end may be withdrawn through the gap provided between the fingers 23 by the lug 25 at the end of the strip. The means for connecting the curved end of the wiper arm 2 to the yoke 5 is described with reference to Fig. 2 (not shown). Specification 675,849 is referred to.

Title: Improvements in means for regulating the working of internal combustion engines
IPC: F02D1/00
Filed: 1927-04-29
Abstract: 270,326. B³chi, A. April 30, 1926, [Convention date]. Cam-actuated pumps; stroke, varying; regulating.-The supply of fuel to an internalcombustion engine is regulated according to the working condition of the air-compressor, either by the pressure of the charging-air, or by the pressure in, or in the supply to, an exhaustdriven turbine actuating the compressor. Fig. 2 shows a fuel pump 22 driven by an eccentric 20 and supplying the engine cylinders by a pipe 25. In addition to the usual regulation of the fuel pump by variation in the time of closing of the suction valve 24 by a governor 8 acting to adjust an eccentric 27 which actuates a plunger 28 and lever 29, the closing of the valve 24 is further controlled by the action of the charging-air pressure and the exhaust or exhaust-turbine pressure on a piston 34. The air is supplied by a pipe 18 and the exhaust by a pipe 19, to opposite sides of the piston 34, which is further acted on bv a spring 37, and is connected by linkage 36 to an eccentric mounting 30 of the lever 29. Hand adjustment is also provided by means of a screw actuated by a hand wheel 38. In a modification, the piston 34 is arranged to hold the suction valve 24 more or less open, so as to reduce or interrupt the supply of fuel, and an additional hand adjustment acts through a lever on the eccentric mounting 30. In another form, the governor acts on an axially-sliding cam to vary the stroke of the fuel pump, and the piston 34 actuates a cock in the fuel supply to the pump, so as to cut off this supply when the charging-air pressure falls too' low or becomes excessive. In the form shown in Fig. 7, the fuel pump is regulated by a hand lever 40, the movement of which over a segment 43 is restricted by a stop 44 connected to the piston 34. A handle 38 connected to the piston 34 allows hand adjustment of the stop. According to the Specification as open to inspection under Sect. 91 (3) (a), the fuel supply may be regulated by a speed regulator on the exhaust-driven turbine, or by the voltage from an electromotor driving the compressor. This subject-matter does not appear in the Specification as accepted.

At the end of the stroke the cylinder is locked and the piston retracted, Fig. 4 (not shown). This procedure is then repeated. The blocking keys may be operated hydraulically or mechanically. The piston 11, Fig. 9, has a central bore 20 in which a piston 12 connected to the cylinder 2 is slidable. The hydraulic fluid is selectively introduced through ducts 14, 16, 18 in the piston rod. The press is used for light scrap metal.

Abstract: 216,140. Gelsenkirchener Bergwerks- Akt.-Ges., and Hock, H. May 16, 1923, [Convention date]. Separating gaseous mixtures by liquefaction.- Low temperature distillation gases are treated for the separation of light oils and hydrocarbons of low boiling point by being subjected to compression and subsequent liquefaction bv expansion in a vessel in which they are subject to a counterflow of cooling liquid, any carbonic acid, sulphuretted hydrogen, and water vapour being previouslv removed. The condensation of the hvdrocarbons may be carried out fractionally, at different pressure stages. The Specification as open to inspection under Sect. 91 (3) (a) states also that gases from the low temperature distillation of coal and other carbonaceous substances are treated with solvents such as acetone at increased pressure and reduced temperature to obtain hydrocarbons of the olefine and paraffin series, these hydrocarbons being recovered from solution by heating or reduction of presure and condensed to form a linuid of high calorific value and suitable for illuminating or heating purposes or for internal combustion engines. The oil used for absorbing these hydrocarbons is, after the latter have been driven off, used again for absorption purposes. This subject-matter does not appear in the Specification as accepted.

Title: Process for the removal of pyrogens from pharmaceutical preparations for injection
IPC: C07K14/315
Filed: 1957-04-12
Abstract: A process for removing pyrogens from pharmaceutical preparations intended for use by injection comprises the addition of a phosphate of calcium, strontium or barium to the sterile solution of the preparation and the subsequent removal of the phosphate after a period of at least two minutes, the said manipulations being carried out under aseptic conditions.  The phosphor may be allowed to form in situ by the addition, first of a soluble phosphate and then an addition of an ion which will form the insoluble phosphate.  The pH of the sterile solution should be between 8 and 10 during the treatment with the phosphate, which preferentially adsorbs the pyrogens.  Any amount of phosphate may be used so long as it is possible to form a precipitate capable of being centrifuged or otherwise removed, but it is preferred to use between 0.025 and 0.15 milligram equivalents of the phosphate per mol. of the sterile solution.  The examples illustrate the removal of pyrogens from preparations containing bacterial hyaluranidase, streptokinase-streptodornase, heparin, and choriogonadotrophin. The treated solution may be that to be used for injection, or one formed during the recovery or synthesis of the particular active ingredient, in which case the treated solution may be further treated to yield the active ingredient in a thus purified solid form which may then be made up into a form suitable for injection. Specification 766,993 is referred to.
