Title: Apparatus for removing volatile constituents contained in liquid synthetic plastic melts
IPC: B29C48/38
Filed: 1962-12-17
Abstract: 989,449. Removal of volatile constituents from plastic melts; evaporators. FARBENFABRIKEN BAYER A.G. Dec. 17, 1962 [Dec. 22, 1961], No. 45768/62. Heading BIB. An evaporator for removing volatile constituents from plastic melts comprises a vertical cylindrical chamber 8, in which rotates a worm 9 so that the edge of its thread is in wiping contact with the inside wall of the chamber, the lower section of the chamber having an annular horizontal slot 11 which communicates with an annular chamber 13 connected via outlet 14 to a vacuum pump (not shown). The evaporator is heated by radiant heating means 25 and heating jacket 24. The plastic melt to be treated enters chamber 8 via line 1, gear pump 2, pipe 4 and worm 5, and flows down the hot inside surface of the chamber and the thread of worm 9. The volatile constituents are vaporized and the vapours pass into chamber 13 via slot 11, and are withdrawn via outlet 14. The edges of slot 11 are sharp, and a lip 12 is provided on the lower edge to prevent the plastic melt entering chamber 13. Any foaming of the plastic melt will occur in the upper section of chamber 8, and will have subsided by the time the plastic melt passes slot 11. The plastic melt leaves chamber 8 via worm 16, and passes into discharge outlet 17. Some of the plastic melt flows back to the worm 16 via passage 18 and capillary tube 20, and the pressure of this recirculated material is measured by pressure sensitive device 19 connected to pressure gauge 26, which controls gear pump 2 via pipe 21 and variable drive means 3. The plastic melt is removed from outlet 17 by gear pump 22. One example is given of the removal of monomeric caprolactam from a melt of polycaprolactam. Also described is a modification of the evaporator wherein the central worm, at the annular slot, meshes with a worm wheel in such a way that the plastic melt is scraped from the worm.

IPC: C21D1/60
Filed: 1963-12-10
Abstract: A method for quenching metal or alloy, particularly ferrous metal such as steel or cast iron but including other metal such as aluminium, comprises contacting a heated metal or alloy e.g. at a temperature above its austenite start temperature, with an aqueous solution of a liquid water-soluble polyalkylene glycol, the water-solubility of which decreases as temperature increases.  The glycol preferably contains oxyethylene and higher oxyalkylene units, e.g. oxybutylene or oxypropylene, and has a molecular weight of 600-40,000.  The solution may comprise 0.1-30% polyalkylene glycol and 45-99.9% water, the remainder, if any, being corrosion protection additives such as nitrites, glucomates, phosphates, silicates, borates, or hydroxides, e.g. sodium nitrite and meta-borate.

Title: Digital print and punch tape recorder
IPC: G06K1/00
Filed: 1974-11-13
Abstract: 1438928 Selective printing LEUPOLD & STEVENS Inc 13 Nov 1974 [5 Dec 1973] 49201/74 Heading B6F [Also in Divisions G4 and B4] In a recorder, data supplied via electronic memory means is printed on and punched (using cam means) into a tape. The memory means is a counter consisting of a shift register recirculating through a full adder. To record road traffic, pulses from pneumatically-actuated road tube switches are supplied via flip-flops to a central processing unit from which they are sent to the adder to be counted in. The count can be recorded (printed and punched) on the tape at a slower rate by the central processor which, by means of pulses supplied to the adder via complement logic, reduces each digit of the stored count in turn (most significant first) progressively (e.g. subtracts a thousand repeatedly) to discover the value of each digit. Each digit is printed and punched by rotating a shaft 80, carrying a print wheel 88 and a set of cams 74, from the position used for the previous digit (i.e. without homing between digits) to the required angular position, then raising a head carrying a spring-biased print anvil 92, the tape 22 and a set of punch pins 30, so that the print wheel presses the tape against the print anvil and some of the cams arrest the upward movement of the corresponding punch pins to cause punching. The recorder is portable and battery-operated. The tape is advanced intermittently by a pawl and ratchet arrangement driven by the same motor that raises the head carrying the print anvil, &c.

Abstract: 1491723 Milling cutters VALERON CORP 15 Nov 1974 [16 Nov 1973] 49448/74 Heading B3K  A rotary cutting tool comprises a shank 10, 12 to which is secured an indexable polygonal cutting insert 28 by way of a screw clamp 32 which holds the insert against a seating surface 26 in an annular groove 13 in one end of the shank. The seating surface 26 is so positioned that the cutting face 46 of the insert lies in a plane parallel to the axial plane of the shank and hence provide a negative cutting rake angle determined by the diametral line 36 in Fig. 4. The "offset" position of the insert also prevents the inoperative cutting of the insert from being damaged or damaging the side surfaces 14 of the groove which supports the sides of the insert. The angle of the groove 13 and the "offset" of the insert being correlated to obtain appropriate side support and rake angle of the insert. A plurality of inserts may be provided equally spaced around the axis of the shank.

Title: Cine camera

Abstract: 1411570 Cinematography K VOCKENHUBER and R HAUSER 30 Oct 1972 [28 Oct 1971] 49991/72 Heading G2E A camera for producing double exposures includes a motor 2 driving a take-up reel in a cartridge 1 through a one way clutch 10 and a film claw 7. Control member 29 activates an assembly which initially reverses the drive to the cartridge 1 but not the claw 7 during a first exposure, then reverses the claw drive and finally during a second exposure drives the claw forwards and causes film take-up to be resumed. In operation, when member 29 is moved to the right, followers 30, 31 track cams 27, 28 respectively, the cams being driven from shaft 23 through clutch 25 being engaged. Cams 27, 28 are sectors enclosing 120 degrees and 240 degrees respectively. Followers 30, 31 perform electrical switching. Follower 30 selectively switches the motor 2 between forward and reverse and selectively energizes coil 40. Follower 31 selectively energizes coils 21, 22. During the first 120 degrees of rotation of the cams both followers lie in the rebated portions of the cams. Motor 2 thus runs in reverse causing clutch 10 to absorb the drive and coil 21 is energized so that gear trains 50, 17 and 16, 15, 51 ensure the claw 7 still feeds the film forward. In the next 120 degrees of rotation follower 31 mounts the sectored part of cam 28 so that coil 22 is energized causing claw 7 to reverse. In the third 120 degrees of rotation follower 30 mounts the sectored part of cam 27 to switch the motor 2 into forward motion (the claw therefore resumes forward feed and film take-up is resumed) and de-energizes coil 40 so that member 29 is restored by spring 29 to the position shown. In another embodiment the motor 2 is not reversible and a cam controlled reversing device is located between the worm-wheel 9 and clutch 10.

The resistors may be replaced by photo-cells or transistors. The formant fitters may be included in the generator circuits and arranged to control the output frequencies of the generators (Figs. 3, 4, not shown). Each fitter may have a plurality of resonant frequencies, one to determine the ultimate pitch of the generator, and others to determine the ultimate formant. The ratio of the resonant frequencies may be 1 : 2 for simulating open organ pipe tones, or 1 : 3 for simulating stopped pipes, or may be non-integral for imitating reed pipes (Fig. 5, not shown).

Abstract: In a continuous non-catalytic process for the production of an alkyl chloride having 3-6 carbon atoms by esterification of the corresponding alkanol with hydrochloric acid at 100-140 DEG  C., the reaction mixture is such that it contains 30-45% by weight of water and 13-17% by weight of hydrochloric acid.  The process is particularly applicable to the preparation of butyl chloride. The Specification describes suitable apparatus for carrying out the process wherein the reaction circuit comprises a reactor and a vaporizing and dispersing device in which the reaction mixture is vaporized prior to entering a distillation column which has a decanter at the level at which the by-product alkylene oxide is selectively concentrated, the said decanter being connected to a secondary column wherein the ether is isolated, the head vapour from the main column being passed to a condenser and thence to a decanter in which the alkyl chloride is separated from the water. Examples describe the preparation of butyl chloride.
