Inventor: EISENBERG BERNARD C
IPC: B65B25/04
Filed: 1968-07-15
Abstract: 1,220,960. Cutting and packing elongate articles. B. C. EISENBERG. 15 July, 1968 [21 July, 1967], No. 33661/68. Heading B8C. [Also in Division A4] Cucumbers 17 fall one at a time from a feeding device 15 into a hopper 18, are centred by interconnected sets of rollers 37, 36 and are pushed by reciprocating plunger assembly 25 through radial slicing blades 19 to slit them longitudinally into segments 17a which are moved through individual twisted shoots 20 which guide them into a jar 21 with their longitudinally-slit surfaces outwards (to improve appearance); the shoots 20, hopper 18, blades 19, plunger assembly 25 and jar 21 are rotated in unison about a vertical axis so that the segments 17a are flung outwards against the wall of the jar 21. Feeding device 15. Cucumbers 16 (Fig. 9) are loaded by an operator into pockets 61, 67 &c. on an endless chain 62 intermittently driven by a reciprocating pneumatic piston and ratchet arrangement controlled by limit valves, to advance the cucumbers 16 past cutting discs 68 which determine the length thereof prior to their falling into the hopper 18. Plunger assembly 25. Flexible pushers 25a in the form of beads strung on metal threads are secured to a rotated shaft 88 slidable through a casing 90 rotatably mounted on an arm 91 which is latched at 92e to a rod 83 sharing a cross-head 82 with the piston-rod 81 of a pneumatic cylinder 80. When a cucumber 17 falls into the hopper 18, the piston-rod 81 is retracted and the arm 91 moves to the chain-dotted position (Fig. 1) where it becomes unlatched from the rod 83, while the casing 90 moves into the hopper 18 and a pin 90a thereon engages a slot 18a in the hopper 18 to synchronize rotations, and the cross-head 82 continues to descend taking with it the flexible pushers 25a which enter the shoots 20 to force the segments 17a into the jar 21. Jar feeding apparatus.-Jars 21 are carried in single file by conveyer chains 51. When a jar is located above an elevator platform 22 (dashed lines in Fig. 1) a control valve is operated and acts to advance a bifurcated gate which engages each side of the jar 21 and a further valve operates to cause cylinder 23 to raise the jar 21 into frictional engagement with the rotating pulley 26. Spaced pins on chain 62 (Fig. 9) operate a valve after every third cucumber so as to lower the filled jar 21 back on to the chains 51. Pneumatic control circuit.-In Fig. 12, the circuit ensures that the apparatus will stop if the control valves are not operated. Additional segments may be inserted in random orientation into a jar filled by the apparatus.

Title: Semiconductor diode
IPC: H01L29/00
Filed: 1961-09-22
Abstract: 994,883. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Sept. 22, 1961 [Sept. 29, 1960], No. 34043/61. Heading H1K. A semi-conductor diode comprises a first zone of one type of conductivity disposed within a second zone of the opposite type with a multiplanar junction therebetween, the resistivity of the first zone being greater than 100 ohm cms. and of the second less tnan 10 ohm cms. Fig. 1 shows a PN junction diode suitable for reverse biasing to form a voltage variable capacitor comprising a 100 to 1000 ohm cm. N-type zone 1 in a 10 ohm cm. P-type zone 2. A variable reverse voltage may be applied from battery 13 which modifies the extent and shape of the depletion zone, particularly in the central N-type region and thus provides a variable capacitor. The resistance of the diode is also variable with the applied voltage so that the device may be used as a phase-shift network or as a voltage-variable resistor if the applied frequency is high enough to render the capacitance ineffective. It is also stated that forward biasing of the device provides characteristic as shown in Fig. 2 which possesses a negative resistance region, a constant current region and a constant voltage region. Fig. 4 shows a circuit in which a variable bias from voltage source 24 is used to control the effect of the PN diode which is acting as a phase shifter to vary the signal from source 25. Other devices with P and N regions of different shapes to achieve the same effect are also described.

Title: Improvements in and connected with thermostats for safety control of oil, gas or powdered fuel furnaces
IPC: G05D23/02
Filed: 1930-11-12
Abstract: 369,618. Thermostats. SATCHWELL, L., Farnham Road, Slough, Buckinghamshire. Nov. 12, 1930, No. 34055. [Class 64 (ii).] A thermostatic switch for the control of furnaces comprises two thermal elements of different mass area relations, so that one changes temperature more rapidly than the other, and of slightly different coefficients of expansion. The elements are preferably an outer split tube B of thin metal having strengthening ribs C, and an inner tube or rod D of less expansibility. These elements are secured together at their outer ends and the outer element is welded to a fixed plate F of a switch A, while the rod D carries a screwed pin H adjustable by an arm K and lock nut L and adapted to engage the switch element. The switch is preferably of the type employing contacts under the influence of a magnet, and the action of the whole device is such that after establishment of flame in the furnace the rapid expansion of the outer element moves the pin H from the switch to allow it to open and subsequent expansion of the inner rod brings the pin back to a position ready for immediate reverse actuation of the switch on sudden' fall of temperature.

Abstract: 411,434. Bobbins &c. SCHWARZ, P., 3, Diekerstrasse, Barmen, Wuppertal, Germany. Dec. 1, 1932, No. 34065. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 2, 1933.] [Class 120 (iii) ] In a metal spool of the type in which the barrel a is inserted into a central boss-shaped portion 1 in the flange b, Fig. 4, each flange is provided around its central boss with an inwardly directed crease 2 having at least one substantially conical wall, so that on bending the barrel end outwardly, the crease engages the barrel tightly. The barrel may either be cylindrical and be inserted in the boss-shaped portion 1 and bending over subsequently effected, which latter operation may be facilitated by making an indentation 3 in the boss-shaped portion, Fig. 5, axial pressure being finally applied by dies 6, 7, Fig. 6 ; or the ends of the barrel may be spun out before insertion ; or the barrel may be forced into a flange, the crease 4 of which has already been turned over, final axial pressure not then being essential. In a modification, the outer wall of the inwardly directed crease 2 is conical and extends to the edge of the flange b, such conical surface being flattened by axial pressure during assembly. In further modifications, the top of the boss-shaped portion 1 is level with the periphery of the flange b before assembly. The mounting hole f is preferably not formed until after the formation of the indentation 3, to avoid distortion of the hole.

Abstract: 1,132,861. Packaging stockings. PRETTY POLLY Ltd. 1 Aug., 1966 [10 Aug., 1965], No. 34109/65. Heading B8C. A method of packaging ladies' stockings comprises winding the stocking 12 about a widthwise axis intermediate its ends within a sheath 20 into a spiral roll 38 which commences at its centre as and continues for at least a substantial part of the roll as a two-start spiral, placing a tube-like receptacle 37 on sheath 20, and then separating the sheath from the roll and receptacle by relative axial movement, leaving the roll within the receptacle. A twostart spiral roll stocking package of the above type is also claimed. As described, the roll 38 is formed on a winder 15; sheath 20 has a cleft 22 for inserting the stocking into a cleft 16 of winder 15 when clefts 16, 22 are horizontally disposed. After winding, casing 37 is slipped over sheath 20 and the latter driven through 90‹. The operator presses casing 37 into one or both of slots 21 in the sheath and removes roll 38 from winder head 20 by frictional engagement with the casing 37. A number of the resulting packages may be inserted into separable pockets 40 of a web 41. Alternatively the receptacles themselves may be joined side by side along tear lines. The receptacles may have closure flaps. A sheet of paper may be incorporated in the outermost convolution of a roll 38, and each roll may comprise two simultaneously rolled stockings. The apparatus may include a butterfly cam (30), Fig. 2 (not shown) so that cleft 16 ends up parallel with bench top 11 when rotation ceases.

Title: Improvements in or relating to duplicating machines
IPC: B41L11/00
Filed: 1956-11-08
Abstract: 811,761. Copying documents. RITZERFELD, W., and RITZERFELD, G. Nov. 8, 1956 [Nov. 22, 1955], No. 34122/56. Class 100(2) A duplicating machine for printing lines or sections from a master sheet on to copy sheets comprises a printing element, a counter pressure element, and hydraulic means for creating pressure between the elements for printing. The counter pressure roller 12 is moved towards or away from the printing drum 1 by a toggle mechanism 14, 15 and rod 21 operated by a hydraulic piston 20 controlled by the setting of a valve 19, liquid from a container 17 passing by means of a pump 18 to the valve. Spring-urged valves 23, 24 leading to liquid return passages limit the pressure on the piston. The spring pressure of the valve 24 is adjustable by a lever 29 to vary the printing pressure. Rotating synchronously with the drum 1 is a disc 33 carrying a series of pins S1-S10 each settable in one of two positions, in one of which it trips a lever 36 and swings it counterclockwise so as to set the valve 19 in position F and cause the printing pressure to be applied at the time that the line or section of the master sheet 2 corresponding to the set pin arrives at the printing position. A lever 46 may be set so as to restore all set pins after they have passed the lever 36, or so as not to restore the pins in the case of repeat printing of the same lines. A lever 44 can be moved so as to prevent clockwise movement of the lever 36, so that the valve 19 is held in position F, for printing the whole text. In another form, a control arm connected to one side of an electric supply source revolves over a disc synchronously with the drum so as to contact in succession a series of contacts corresponding to the lines of the master sheet. The lines to be printed are selected by keys, depression of a key connecting the corresponding contact to the other side of the supply through a magnet, energization of which causes a rod to be attracted and move the valve 19 to position F.
