Title: Improved process and apparatus for the production of inspissated sugar fruits and vegetables
IPC: A23B7/08
Filed: 1932-02-24
Abstract: 397,196. Crystallizing fruit. BRAMIGK & CO., Ltd., 15, Creechurch Lane, London. Feb. 24, 1932, No. 5492. [Class 28 (i).] Relates to the crystallization of fruit and vegetables, the fruit &c. being placed in wire gauze baskets in a container f which together with a preheater g is filled with cold water which is heated bv steam and circulated through the pipes e, w until the desired temperature is attained. The cold water is supplied from a tank a, pipe b and valve s, and the steam enters the heater g through a pipe q and leaves through a pipe r. The fruit is kept in the hot water until it becomes soft, when the pump c is started to pump weak warm syrup from the pan h into the container f. The syrup displaces the water which escapes through the valve u and the overflow v. When the container f is full of syrup, a vacuum pump m, having an exhaust open to the atmosphere, creates a partial vacuum in the container f which assists the syrup in penetrating into the fruit. After an appropriate time, the pump m is stopped and further syrup is forced under pressure into the container f by the pump c. This pressure is maintained for a desired period, preferably by automatic means, e.g. a diaphragm which controls the switch of the motor of the pump c. The valves x, y, z<1> are then opened and the remainder closed, the vacuum pump m is started, and the weakened syrup is withdrawn from the container f into the vacuum pan for reconcentration. Additional sugar is added in the pan which is provided with beaters h<1>. The strengthened solution is then pumped back into the container f which is again partially exhausted by the pump m, pressure is again applied and the process repeated until the fruit is sufficiently impregnated. For certain kinds of fruits, such as citrous fruits, it may be desirable to insert a separator o between the pump m and the pan h whereby oils and fruit juices may be separated.

Title: Improvements in control mechanism for printing and other machines
Inventor: WARNER-JONES KENNETH
IPC: F16H53/08
Filed: 1954-02-26
Abstract: 802,999. Cam mechanism. WARNERJONES & CO., Ltd., K. Feb. 25, 1955 [Feb. 26, 1954], No. 5670/54. Class 80 (3). [Also in Group XVI] A mechanism for converting rotary motion to oscillatory motion comprises a rotating shaft 1 carrying cams 2, 3 and a rocking shaft 5 which carries a lever 7, on the free end of which is displaceably mounted a cam follower 13 adapted to co-operate with one cam or the other so as to displace the shaft 5 into one of two control positions. The cam 2 acts on its outer surface and serves to displace the lever 7, shaft 5 and control lever 6 in an anti-clockwise direction into the full line position of lever 6. The cam 3 acts through an inward facing surface 12 and serves to rock shaft 5 in the opposite direction. The follower 13 is slidable from the left-hand position shown, where its end 9 engages cam 2, to the right-hand position where its end 10 engages the surface 12 of cam 3. The position of the follower is controlled by a lever 14 connected by vacuum-operated bellows 16, 17. Alternatively the lever may be displaced mechanically or electrically. Since the cams 2, 3 are only quadrants, the shaft 5 has to be held for the remaining part of the revolution in the position to which it was last moved. For this purpose another lever 8 co-operates with a disc 4 having circular tracks 20, 21 to receive a follower 11 on lever 8. The grooves are separated by a wall 22 in which is formed a gap 23 allowing the lever to be moved from one position to the other. By controlling the bellows 16, 17 through a rotating valve a desired sequence of operative and non-operative revolutions of the printing machine is obtained. This may be used for instance to print alternate forms and leave the others blank. The mechanism may otherwise be applied to the operation of numbering units so as to reprint numbers as required. Other applications are to delivery mechanism folding mechanism, perforating or punching apparatus.

Filed: 1970-02-06
Abstract: 1,247,826. Gloves. AKWELL INDUSTRIES Inc. 6 Feb., 1970 [12 Sept., 1969], No. 5800/ 70. Heading A3V. A unitary elastomeric glove to fit tightly over a wearer's hand and lower forearm comprises an open end cuff portion 18, to receive the end of a garment sleeve, which includes spaced circumferential bands 22, 24, adjacent the open end, of thicker material than that of the other parts of the glove. The glove thus grips the sleeve between the bands and is suitable for use, when sterilised, by a surgeon. A terminal bead 21 formed around the open cuff end may form one of said bands and the thickness of the material, other than that of the bands, is within the range 0.005-0.010 in. and is substantially uniform. The thickened bands may be formed by applying coagulants to the glove material during the moulding stages of formation and are usually 2-3 times as thick as the rest of the glove, the widths of these bands being in the range 3/8-3/4 in. For use as a surgical glove, when the material is as thin as possible, the material may be 0.005 in. thick apart from 0.014 thick bands which are 1/2 in. wide and separted by 1¢- 2¢ inches. The unthickened band of material 23 bulges in use to accommodate the material of a garment sleeve which is trapped between the thickened bands.

Title: Improvements relating to magnetic sound recording or reproducing apparatus
Inventor: DUTTON GILBERT FARADAY
IPC: G11B25/04
Filed: 1950-03-08
Abstract: 714,145. Magnetic sound recording and reproducing apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 1, 1951 [March 8, 1950], No. 5811/50. Class 40 (2). A transducing head 9, erasing head 16 and a tracking disc 21 are carried by a plate 4 pivoted about an axis 5. The head 9 is mounted on a carriage 8 which slides on rails 6, 7 under the action of a tracking wheel 10 which engages the disc 21. The erasing head 16 comprising a permanent magnet, may be lowered onto the record by moving a lever 18. The tracking wheel may be released from the disc 21 by depressing a plate 14, which action may also lift the transducing head. Movement of a stud 15 effects back-spacing; and the distance between the wheel 10 and the head 9 may be adjusted by a knob 13. In a modification, Fig. 2, the disc 21 may be replaced by a clutch member 31 which is driven either directly from the centre spindle or from the turntable. Rotation of the member 31 causes a lead screw 35 to rotate which engages a spring-loaded wheel 36 on a carriage for the head 9, thus causing the head to be tracked across the record. The wheel 36 may be moved against its spring away from the screw to allow the head to be moved independently of the screw. Back-spacing is effected by an electromagnet controlled by a switch. In both the constructions shown in Figs. 1 and 2, the plate 4 may be held in its operative position by locking bars 43, 44, Fig. 2, which engage in slots 41, 42 in fixed brackets. When a knob 26 is moved, a spring-loaded cam 45 releases the bars from the slots and the plate 4 is raised by springs. When the plate is lowered again, the bars automatically slip into the slots. An indicator 27, Fig. 1, may be fixed to the carriage to co-operate with a time scale 28. A cueing pointer 29 may also be fixed to the carriage and it co-operates, with a cueing pad 30 on the plate 4. The upper surface of the turntable, and the bottom of the tracking disc 21, and the clutch member 31 may have rubber friction pads. In a further modification, Fig. 3, the plate 4 is of rectangular shape. An indicator 49 is moved by a cord attached to the transducer carriage. The erasing head may be in the form of an electro-magnet, the current to which is applied by a press button switch, the actuation of which may also cause the turntable to be rotated. The plate 4 is locked by latches 51, 52 which are released by depressing a stud 55. The apparatus of Fig. 3, may have the tracking mechanism of Fig. 2 instead of the disc 21, in which case the tracking wheel may be connected to the transducing head by a flexible wire. In a further modification the lead screw instead of being driven by a clutch member 3. Various parts of the apparatus which are not described identical may be constructed as set forth in Specification 697,161. According to the Provisional Specification the central part of the record disc may be printed for use in noting memoranda.

Title: Improvements in or relating to the manufacture of grooved wheels and the like
IPC: B23F1/04
Filed: 1945-03-15
Abstract: 591,013. Shaping-machines. SANDOR, B. T., ESCHENAUER, J.,and MECHANICAL LIGHTERS & ENGINEERING CO., Ltd. March 15, 1945, No. 6476. [Class 83 (iii)] In a shaping machine for cutting the teeth of wheels such as the spark wheels of pyrophoric lighters, the work is indexed between each stroke of the cutter and after a complete revolution of the work a clutch is opened to stop the machine. The main shaft of the machine consists of two parts 2, 2a, carrying clutch members 3, 3a whereof the part 2 is driven by an electric motor or otherwise. A cam 4 on the clutch 3a reciprocates a cutter ram 19a carrying a roller 19 and a vertically and angularly adjustable cutter 19b and a further cam 5 on the shaft 2a actuates an arm 23 to rock a fork 22 having an abutment adjustable by a screw 24 engaging a pawl 21. This pawl acts on a toothed wheel 20 secured to the headstock spindle 15 which terminates in a mandrel 16 carrying the work 25. In operation, with the clutch 3, 3a open and the machine stationary, the .operator rocks a lever 12 to move a slidable plate 11 out of contact with a notch 13 on a disc 14 attached to the spindle 15, thereby causing a pin 10 on the .plate to rock a lever 6, pivoted at 7. The lever 6 moves clutch part 3 to engage the clutch and cause shaft 2a to be rotated, thus causing the cutter to be reciprocated by cam 4 and the work indexed by cam 5 between cutting strokes, and when the work has completed a revolution, the plate 11 drops into the notch 13 to release lever 6 which is then rocked by a spring 8 to open the clutch and stop the machine. The work 25 may be prevented from rotating on the mandrel 16 by serrations thereon, and is forced on the mandrel by a tailstock 29 carrying a ball bearing 28. If several work pieces are being operated upon simultaneously the burrs produced during cutting may be used to prevent rotation of the succeeding ones, or the blanks may interengage with each other, or the tailstock 29 may have a rib &c. to engage the end blank. The cutter may be adapted to operate on the internal periphery of a blank, and the cutter slide may be at an angle to the mandrel axis for the production of inclined teeth on the work, the roller 19 then having a curved surface. The periphery of the work blanks may be provided with circular or helical indentations or may be knurled before the teeth are cut thereon.
