Title: Temperature controlled systems
IPC: B29C45/73
Filed: 1972-04-21
Abstract: 1391848 Temperature control of injection moulds CHURCHILL INSTRUMENT CO Ltd 16 March 1973 18598/72 Heading B5A [Also in Division G3] A temperature control system controls the temperatures in mould halves 8, 11 of a plastics injection moulding machine, by controlling the temperatures of fluid (e.g. water) in a heating fluid circuit including mould half 8 and a cooling fluid circuit including mould half 11, to hold the respective temperatures substantially within a respective predetermined range and to maintain half 8 at a higher temp. than 11. In general if the temp. of water in the HW circuit increases beyond a given max. water from the CW circuit is mixed therewith. If water in the CW circuit falls below a given min. then water from the HW circuit is mixed therewith. As shown, the HW circuit includes a pump 1, a heater 6 and the mould half 8. The CW circuit includes a pump 2, cooler 9, and mould half 11. Max.-min. thermal switches 7, 10 are responsive to the temperature of the heating and cooling water respectively. Cold water is fed initially to the circiuts form a source 17 via a one way valve 18. Volume balance of water in the circuits is maintained by a passage 16 linking equal pressure points.  In operation, with the water temp. less than the min. set by switch contacts 7a and 10a. The heater 6 is energized and a solenoid valve 15 in a transfer passage 14, is opened. The temp. of water in the HW circuit increases and some is drawn into the CW circuit. When the CW temp. is higher than the min., the valve 15 is closed by switch 10 and likewise, when the HW temp. exceeds the min. set by switch 7, the heater 6 is deenergized. The pumps 1 and 2 continue to circulate water through the mould halves. With hot plastics material in the mould 8, 11, the water temp. in the two circuits will tend to increase. If this causes the max. contact 7b to be engaged by contact 7c then a solenoid valve 13 will be opened so that relatively cooler water from the CW circuit will be drawn by the pump 1 via a transfer passage 12 to the HW circuit. If the CW circuit temp. exceeds its max. then switch 10 will open a solenoid valve 21 to pass cold water from the inlet 17 through the cooler and out via a drain 20 until the CW temp. drops below its set max.

Title: Power driven stapling machine
IPC: B25C5/13
Filed: 1964-05-06
Abstract: 1,013,995. Stapling machines. W. SCHAFROTH. May 6, 1964 [May 13, 1963], No. 18941/64. Heading B4C. A power-operated stapling machine comprises a stapling mechanism 3 driven downwardly by a pneumatically-operated piston 7 upon actuation of a valve 21 by a trigger 2, and stop means 39, 40 for contacting the underside of the piston in order to actuate a trip lever 32 and thereby move the valve to cause compressed air to raise the piston and exhaust the air above it. The trip-lever 32 is mounted on rollers 51 in the trigger 2 which is pivoted on a pin 47 in the machine housing the lever being normally loaded by a spring 46 to the position shown in Fig. 4. In operation, upon activation of the trigger, the valve 21 is raised by the abut. ment of the lever 32 with an extension 22 on the valve, air then being directed from a reservoir 1 via passages to act upon the top side of the piston thereby driving it downwardly. Nearing the end of the stroke the underside of the piston abuts a spring-loaded pin 39 which strikes the lever 32 so as to cause the extension 22, under the action of a spring 30, to enter a hole 63 in the lever and thereby allow the valve to return to the position in which air is fed to the underside of the piston to return it. Passages are provided so that exhaust air, together with an oil mist, flow over the stapling mechanism 3 which comprises a staple driver and a retractable anvil. The bottom edge of the driver is chamfered in order to co-operate with a similar front edge of the staple pusher 62 so that, if the machine is operated after the last staple has been used, the driver merely strikes the front edge of the pusher and so moves the latter rearwardly. A buffer spring 12 is mounted on the piston rod 9.

Filed: 1962-01-26
Abstract: Novel compounds of the general formula: <FORM:0966837/C1/1> where R is nitrophenyl or cyanomethyl group and X is a halogen atom, the two alkyl groups in the 5-position are identical and the asterisks denote that the conformation of the bonds on carbon atoms are appropriate to an alpha glycoside, are made by halogenating, with concommittat ether fission a glycoside of the general formula: <FORM:0966837/C1/2> where the terms are as defined above. Preferred are the 2-O-benzoyl or para methoxy benzoyl derivatives. Per se claimed are 5, 5-dimethyl -4- (O methyl) -3- (O p-nitro-phenyloxy carbonyl) -2- (O benzoyl) -L- alpha lyxopyranosyl bromide, chloride and fluoride. The bromides are prepared by the use of hydrogen bromide in glacial acetic acid, the chlorides by hydrogen chloride in nitromethane or with dichloromethyl methyl ether in the presence of a catalytic amount of a Lewis acid; the chloride and the fluoride may be obtained from the bromide by treatment in an inert solvent with silver chloride or fluoride respectively. A further process for the preparation of the fluoride consists of the successive treatment of the bromide with silver carbonate followed by hydrogen fluoride.  The product may be converted into an aryl glycoside by reaction, in acidic medium with a phenol or a substituted phenol, and if desired the 3-(O substituent) may be replaced by the carbamoyl group e.g. with alcoholic ammonia and the O-acyl group in position 2 can be hydrolysed e.g. by alcoholic barium alkoxide solution. In the examples are described the preparation of 5, 5-dimethyl -4- (O methyl) -3- [O(p-nitrophenyloxy carbonyl)] -2- (O benzoyl)- -L- alpha lyxopyranosyl bromide, its conversion to the chloride and fluoride; treatment thereof with silver carbonate to yield the pyranose and the conversion of the pyranose to the fluoride is also featured. The direct synthesis of the chloride and the reaction of the bromide with orthocresol to yield the pyranoside are also described.
Patent GB-189895-A (GB)
Abstract: 189,895. Stibbe, G. Sept. 14, 1921. Circular machines.-Horizontally striped work is made on spring-beard needle machines with rotary needle-cylinders and individual pressers by the use of feeders with differently coloured yarn, one being automatically thrown out of action at one feed as another is thrown in at another feed. Each feed finger 5 is carried on an inclined shaft 6 journaled in a post 7 on a cap 8. A projection 10 on a collar 9 of the shaft bears against a slide-bar 10<1> lying in a groove in the base. of the post 7, and is operated by a cam 12 forming the upper part of a rotary member connected to a vertical shaft 14, the lower end of which carries a star-wheel 15 operated by projections 16', 16<11> of a member 16 carried by the rotary sinker ring. The feed-finger 5 is positively lifted out of work by a high part of the cam 12 and is forced down into work again when a low part of the cam 12 is against the bar 10<1> by the action of a spring 18 in a boss 19 on a pin 20 bearing against the end 21 of the finger 5. The star-wheel 15 has four arms 15<1>, 15<11> which are staggered in pairs and the shaft 14 is movable vertically to bring one or the other pair within range of the projections 16', 16<11> which turn the star-wheel two quarter revolutions in quick succession. The shaft 14 is shifted vertically against a spring 22 by a bell crank 23, 25, the arm 23 carrying an incline 23<1> while the arm 25 is connected by a rod 26 to pattern control mechanism. When the feeder 5 is thrown out of work the yarn end is caught under a retaining finger 25<1>. Fig. 5, pivoted at 26<1> to a. bracket and provided with a shoulder 28 against which the yarn end lodges. Surrounding the finger 25<1> is a loop 29 upon which the yarn rests. To prevent the needles from pressing off when the yarn is lifted therefrom and is out of work, the shank 37 of the presser cam 4<a> is provided with a stud 38 engaging a slide 39 having an inclined back edge which is operated by a bar or pusher 40 arranged below the slide-bar 10<1> and acted upon by a cam 12b, 12<c>, Fig. 6, secured to the cam 12. The parts are so arranged that just before the yarn finger is lifted out of work the cam 12b causes the presser cam 4<a> to be withdrawn against the action of its spring 41. The position of the presser cam is adjustable by means of a micrometer screw device 42, 43, 44. A guard 36 fixed to the stationary cam ring at a point in the machine circle at which the pressing is done, prevents the pressers 4 from moving out at their lower ends when acted on by the cam 4<a>.

Abstract: 1433968 Change speed control AUTOMOBILWERK EISENACH VEB 2 May 1974 [5 July 1973] 19218/74 Heading F2D Fluid delivered through a conduit 5 to operating means in an automatic transmission of a motor vehicle and controlled as to its pressure P by a valve 4 is supplied either from an enginedriven pump 1 or a road speed responsive pump 2 depending upon which at any instant delivers the higher pressure. As shown, the pressure from pump 1 is higher so that a valve 3 is displaced to the right and the pump 1 discharges through conduits 12, 312, 5 and, through a restriction 51, to an end surface 405 of the valve 4, leftward displacement of this valve against the loadings of a spring 43 and a piston 41 limiting pressure by connecting a passage 11 with exhaust R 1 . One side 413 of the piston 41 is subject to a load responsive pressure P d  controlled, e.g. in accordance with engine throttle opening or inlet depression, and the other side is exhausted through a passage 414 and the valve 3. A higher pressure P is determined by the valve 4 when low ratio or reverse is selected by admission of pressure P or P d  to a surface 409. When the valve 3 is displaced to the left, as pressure from pump 2 exceeds that from pump 1, the pump 2 is connected to the conduit 5, the conduit 312 is cut off [from the pump 1, and the loading applied by the piston 41 to the valve 4 is reduced by connection of the passage 414 to a road speed responsive pressure P v  instead of to exhaust R 3 . The valve 4 then connects the pump 1 to exhaust R 1  and governs pressure in the conduit 5 by controlling a passage to exhaust R 2 .
