Abstract: 1329646 Tool changers; drilling machines B W-WEBER VERWALTUNGS GmbH 18 May 1971 [29 May 1970 4 Dec 1970] 15484/71 Headings B3B and B3C A machine tool comprises a base 1, a headstock 3 slidable along said base in a working direction, and a spindle tool head 4 rotatable about an axis 5 on the headstock at 45 degrees to the working direction, said tool head having a plurality of tool supports 6, 7 having supporting planes inclined equally around the axis 5 and at least two tool supports 6, 7 having supporting planes at a right angles to each other which is bisected by the axis 5. Means are provided to rotate the tool head 4 to a number of positions and to releasably lock it thereat, and wherein one of said tool supports 6 faces in said working direction and another tool support 7 forms an exchanging position at right angle to said working direction. At least two multiplespindle heads 8, 9 are mounted on at least two tool supports 6, 7 and rotation of the tool head 4 through 180 degrees enables a head 8 to operate on a workpiece while head 9 can be exchanged. A magazine 13 is formed of an endless track 17 on which carriages 18, 19 move as an endless train to carry multi-spindle heads to an exchange position. A rack 24 and pinion 25 drive operates a push-pull device 21 having a gripper 26 for moving the multi-spindle heads between the magazine and tool head 4. The magazine is connected to the headstock 3 by a guide track 12 having inner and outer telescopic rails so that a spindle head exchanges can take place at any position of the headstock 3. A sensing device comprising cam operated switches senses the arrival of a spindle head 9 on the tool support 7 and stops its movement smoothly to prevent disturbance of the tools 2 in the spindle head 8 that may be operating on a workpiece during a spindle head interchange. In a second embodiment the tool head 104 has four tool supports that carry a pair of oppositely arranged multi-spindle heads 108, 109 and a pair of oppositely arranged single tool heads 164, 165. Two separate magazines are provided. The single tool heads are carried in a chain conveyer magazine 168 mounted on and movable with the headstock 103 and a fluid pressure operated transfer gripper device 178, 179 is provided. The multi-spindle heads are arranged in two parallel rows of compartments 118 and a carriage 182 having a pivoting beam 184 for extracting the heads moves a selected head in line with a rack and pinion drive device 121 to be fed to the tool head 104. The machine tool is programme controlled.

Abstract: 417,571. Printing - surfaces. MASCHINENFABRIK WINKLER, FALLERT, & CO. AKT.-GES., 36,Wylerringstrasse, Berne, Switzerland. May 24, 1934, No. 15523. Convention date, May 31, 1933. [Class 100 (ii).] In a machine for casting stereotype or backing electrotype of the kind in which the mould a, b is adapted to be pressed against a valvecontrolled opening c of the melting pot and in which, when the mould is opened, the cast plate x hangs from the edge of the core a, fingers e are provided to lift the plate into a position where by a longitudinal movement of the fingers it can be slid out of the mould. The plate is cast with a projection on the concave side for engagement by the fingers. The fingers are attached to a shaft f which can be oscillated by means of a crank n, connection m, and cam i from the main shaft of the machine The cam i also acts, through the connections k, l, to reciprocate the shaft and cause the fingers e to push the plate on to a saddle g through which cooling-water is circulated. The shaft is provided with a wiper w which passes over the edge of the core and the mouldopening to remove any adhering metal. The plate x, when raised by the fingers, raises a lever u connected by a link t to a lever s to lift the inner end thereof out of the path of movement of a projection v on the main shaft. If no plate is present, the projection forces the other end of the lever against a hand-lever p causing it to release a foot-lever q and disconnect the clutch r.

May 28, 1931, No. 15675. Convention date, May 28, 1930. [Class 39 (i).] X-ray tubes are protected against excess consumption by thermal switches which are so connected in circuit as to be heated proportionally to the heat of the anode and on a lower scale. As shown the thermal element 17. carries the current in the primary of the transformer 15 which supplies the current input to the tube. The effective part of the current input to operate the thermal element may be varied by the adjustable shunt-resistance 27. The voltage of the supply may be varied by the potentiometer tapping arrangement shown. In shunt across the applied voltage is a heating element 18 located near the thermal strip which is thus heated in accordance with a measure of the wattage input to the tube and may be designed to reproduce the thermal characteristics of the anode. The cathode 13 is supplied from a potential transformer 14. When the input is so great as to endanger the anode the thermal switch closes its contacts and energizes the breaker 22 to open the supply circuit which is reclosed when the thermal switch cools again.

Abstract: 130,346. Shaw, J. C. Oct. 31, 1917. Preserving meat &c. by cooling and cold storage. A preliminary chilling or cooling is effected under a partial vacuum, the vapours from the meat being withdrawn from the cooling-chamber, and the further chilling carried out by cold air circulation; the final freezing of the meat is effected by direct expansion or by brine circulation in the usual manner. Apparatus for carrying out the above process comprises a series of chambers 1, 2, 3, 4, fitted with direct expansion cooling-pipes 5 connected to headers 6, 7 leading to the ammonia plant 8. Above the chambers 1 - - 4 is a centrally-disposed air-cooling chamber 10 fitted with pipes 11 and a fan 16. This chamber communicates with the passage 12, 13, having openings 14, 15 leading to the chambers 1, 4, and an outlet door 21. The carcases having been placed within one or more of the chilling-chambers 1 - - 4, the doors closing the openings 15 are closed and those of the openings 14 opened. During the chilling by the pipes 5, a partial vacuum is maintained by the fan 16, which draws the vapours &c. from the meat through the openings 14 to the outlet 21. The meat being chilled to about 35‹ F. in 12 hours, the outlet 21 is closed, the doors of the ports 15 are opened, and the air-cooling pipes 11 put into action, so that the meat is further chilled to about 28‹ F. by the cold air circulation for another 12 hours. The openings 14, 15 are now closed, and the meat is then frozen for about six days by means of the pipes 5, when they can be removed to the cold storage room 26.

Abstract: 563,633. Non-return valves. DOWTY EQUIPMENT, Ltd., and KILLNER, F. E. Nov. 17, 1942, No. 16279. [Class 135] A non-return valve, particularly adapted for use as an inflating valve for tyres, oleo-pneumatic shock-absorbers and the like, has a valve member adapted to be deformed laterally into sealing engagement with a conical or cylindrical seat by the pressure operating to shut the valve. The Figure shows the invention applied to an inflating valve. The valve inside is screwed into the usual stem 3 by the engagement of a suitable tool with projections 4 to bring a rectangular packing 5 housed in a groove of greater axial length into engagement with a conical shoulder in the stem 3. The valve spindle 11, loosely mounted in the tubular member 2, carries the deformable member 15 housed in a groove of greater axial length 14 immediately beneath a flange 12 on the spindle. As the valve closes the member 15 passes into a cylindrical seat 9 formed on the lower end of the member 2 and when the flange 12 engages stop projections 13, the pressure deforms the member 15 to complete the seal. The valve is urged towards its closed position by a light spring 16 housed in a recess 17 and bearing against an abutment 18 secured to the spindle by crimping the outer end of the spindle. The member 15 when unstressed may be conical, or may be cylindrical with a chamfered leading edge. According to the Provisional Specification, the flange may seat on the bottom of the seat recess and the valve spindle may be extended inwards and fitted with a flexible diaphragm.
