Title: Bag gathering and clipping mechanism
IPC: B65B51/00
Filed: 1972-01-13
Abstract: 1361142 Closing bag mouths W R GRACE & CO 2 Jan 1973 [13 Jan 1972] 1751/72 Heading B8C A bag-mouth clipping and gathering mechanism comprises a reciprocal die 19 for crimping a clip 11 against an anvil 27 around a bag-mouth, a pair of arms 12 for gathering the bag mouth into a neck, a common reciprocable drive plate 1 coupled to both the arms and the die, and an adjustably biased telescopic strut 14 facilitating selective variation of the crimping force to be applied to the clip. The strut is coupled between the drive plate and an eccentric pin 6 of a motordriven gear, the strut, plate and die being driven upwards on rotaton of the pin to cause the arms to pivot together to gather the bag mouth and the die to crimp the clip about the gathered bag mouth. The strut comprises a set of belleville spring washers mounted on the piston-rod 30b of a piston 30a within a sleeve 30. The piston is coupled to a collar 6a on the eccentric pin by threaded stud 30c. The deforming crimping force transmitted by the strut may be varied by adjustment of the threaded stud/collar connection to change the effective strut length or by. removing one or more of the spring washers, or replacement thereof by incompressible spacers; to vary the spring rate of the strut. The gathering arms 12 are pivoted by pins 14 to the housing 20 of the mechanism and are moved inwardly together on upwards motion of the plate 1 by plate pins 2 engaging in arm grooves 15. The free grooved ends 25 of the arms are held in abutment during the final upwards movement of the die by inclined arm groove portions d so that the passage formed by the abutting grooved arm ends forms a continuation of a guide passage 24 for the clip. A knife 16 is raised to trim excess bag material by engagement of one arm 7 of a bellcrank lever 3 and 7 by roller 6a of the eccentric drive pin 6. In a modification, Figs. 4 and 5 (not shown), the bag mouth gathering arms 44 are pivoted together by eccentric pins 47 of gearwheels 42 engaging in cam tracks 46 on the arms, the gear-wheels being rotated by rack-formations 41 on a reciprocal plate 40. Plate projections 58 engage in arm slots 48 to maintain the arms together during the final upwards motion of the plate and clipping die. An adjustment device 50 is provided on the bell-crank lever of the knife mechanism to vary the lower-most end of the knife stroke. In another modification, Fig. 6 (not shown), the strut 4 is replaced by an hydraulic strut 84 linked by an hydraulic line 78 to a remotely-positioned strut 80, which incorporates removable spring-washers and a screw-threaded stud 88 to permit the spring rate or loading of the strut 80, and hence strut 84, to to be varied. The mechanism is incorporated in a vacuum-packaging arrangement, Fig. 10 (not shown), wherein the bag is placed on a pivotable conveyer, a cover 97 replaced, and the formed chamber evacuated. Alternatively, the bag may be evacuated by means of tube inserted into the bag mouth.

Title: Improvements in or relating to talking machines
IPC: G11B17/02
Filed: 1951-01-31
Abstract: 698,558. Automatic gramophones. PAILLARD SOC. ANON. Jan. 31, 1951 [Feb. 15, 1950], No. 2399/51. Class 40 (ii). When the tone-arm 23 reaches the vicinity of the central record supporting spindle 2, a finger 22 on the tone-arm moves one end of a rod 26, causing the other end to move a pawl 27 on a cam 15 into the path of a projection 28 on the turntable 1. The cam 15 is thus rotated until a boss 36 on a cam 37 disengages the pawl from the projection. As the cam 15 rotates it moves a finger 17 which pivots a lever 16 about a shaft 31 against the action of a spring 18. The lever 16 engages a finger 20 and as it moves it allows a lever 19 to pivot about a shaft 32 under the action of a spring 21. Movement of the lever 19 causes a cam edge on the lever to push the finger 22 and lift the tone-arm until the finger engages the edge of an opening 24. At this moment the lever 16 no longer engages the finger 20, but it engages and moves the finger 22 (Fig. 2, not shown) to move the tone-arm outside the records. At the same time, a ramp 33 on the lever 16 raises a spindle 4 to operate the record supporting members 6, which may be as described in Specification 698,557, and allow the bottom record to fall on to the turntable. The finger 17 is then moved in the reverse direction by the cam 15, and the lever 16 on its return, allows the finger 22 to return until it engages in a notch 30 in the lever 19 and returns the record supporting members. When the finger is in the notch 30, the tone-arm is at its correct distance from the edge of the record. The lever 16 again engages the finger 20 and returns the lever 19, the finger 22 remaining in the notch 30 until the needle engages the record. The levers 16, 19 then continue their movements to their rest positions. The position of the opening 24 may be adjusted to vary the spacing between the needle and the upper disc of the pile. The rest position of the tone-arm may be adjusted by varying the position of the notch 30. For this purpose the cam edge on the lever 19 may be a separate member adjustably fixed to the lever. Alternatively, the position of the pivot point 32 may be varied. The mechanism may be operated manually by moving the rod 26.

Abstract: 969,151. Selective positioning arrangements. GENERAL ELECTRIC CO. Jan. 21, 1963 [Feb. 14, 1962], No. 2491/63. Addition to 959,697. Heading B7N. An improvement in the selective positioning arrangement described in the parent Specification whereby means are provided for compensating for the unequal current division, due to unequal line impedances, when taps other than those centrally positioned on the current carrying line are selected, e.g. assuming tap 9 is selected current I L  is less than current IR, hence the voltage induced in the loop 18 is zero or a minimum value at a point slightly to the left of tap 9. The return current from each end of the line flows through respective halves 23, 24 of the primary winding of transformer 22 and induces a voltage in the secondary 25 which is a function of the difference in the two currents. This voltage is adjustable by means of the transformer core and is connected in series with the pick-up loop voltage in a sense to oppose the voltage induced in the loop due to the current difference.

Abstract: 777,077. Annealing. UNITED STATES STEEL CORPORATION. Jan 29; 1955 [Nov. 10, 1954], No. 2533/55. Class 72. Apparatus for controlling the temperature of moving strip comprises a series of hollow rolls round which the strip passes and means for controlling the surface temperature of the rolls so that it increases from the roll at one end to the roll at the other. As shown, a strip passes from an uncoiler 2, round preheating rolls 16A- 16D, through a furnace having a preheating zone 6, a heating zone 8, and a slow cooling zone 10, and round cooling rollers 16E-16J to a coiler 14. A cold liquid, e.g. a non-inflammable oil or a liquid silicone, enters roll 16J and passes through each roll to roll 16E during which it cools the roll surface while being heated itself. It then passes through rolls 16D to 16A giving up its heat and preheating the strip. It may finally return to a tank containing a cooling coil. The temperature of the liquid may be controlled as it enters each roll of the series in the cooling cycle, by means of a pyrometer operating electrical relays to heat or cool the liquid. The apparatus may also be used to dry strip before entering an electrostatic oiler. Specifications 718,738 and 754,478 are referred to.

Abstract: 1,039,407. Transistor amplifying and frequency-changing circuits. CSF. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 21, 1964 [Jan. 25, 1963], No. 2693/64. Heading H3T. A self-oscillating frequency-changer comprises a transistor whose collector circuit is coupled to a resonant line terminated in a tunable parallel resonant circuit, feedback to maintain oscillation being taken through a capacitor to the emitter circuit of the transistor from a point between a voltage node at the highest frequency of operation and the end of the line connected to the collector whereby the amplitude of oscillation is maintained substantially constant over the operative range. Received signals are amplified in common-base transistor 1 and then coupled from line 80 in the collector circuit thereof to an input line 13 for the frequency-changer transistor 14 through an aperture 34 in a screen 35. Line 13 is coupled magnetically to a line 17 in the emitter circuit of the transistor 14. The collector circuit of the transistor 14 comprises a line 22 terminated in a parallel-resonant circuit and a point X thereon is coupled through capacitor 24 to a point P in the line in the emitter circuit. A further magnetic coupling is provided between line 22 and portion PM of line 17. The point X lies between the end of line 22 connected to the collector of transistor 14 and the nodal point at the highest frequency of operation. It may be shown, Fig. 2 (not shown) that the magnitude of oscillation at the point X related to the amplitude of oscillation in transistor 14 decreases as the frequency increases; since however feedback increases with frequency the oscillation amplitude is maintained substantially constant. Intermediate-frequency output is taken through tuning components 28, 29 from tuned I.F. auto transformer 27, high-frequency being suppressed by coil 25. In modified circuits the coupling between lines 13 and 17 may be capacitive, Fig. 3 (not shown), the magnetically coupled feedback from line 22 may be omitted, Fig. 4 (not shown), or both these modifications applied simultaneously, Fig. 5 (not shown). A capacitor 5 in the base circuit of commonbase amplifier transistor 1 provides with the internal self-inductance of the transistor base circuit a series-tuned circuit resonant at that frequency in the operative range at which the amplifier gain is a maximum, thus providing a low impedance path from base to earth at this frequency and preventing self-oscillation in the amplifier.

Fig. 6 shows a substrate of one conductivity type in which are formed three zones of opposite conductivity type, two 78, 79 of which form the source and drain regions of an IGFET and the other of which 71 forms the body of the limiter. Two high conductivity regions 72, 73 of the same conductivity type as the substrate 77 complete the limiter. As shown the region 72 lies across the boundary between the zone 71 and the substrate. (The region 72 may be formed as an annular region to overlie the entire periphery.) In the variant of Fig. 7 one of the high conductivity regions 72 is an internal region. The design of the devices may be such that limiting is achieved by avalanche or Zener breakdown of that junction of the limiter which is reverse biased at the time or is achieved by punch-through between the two regions. The devices are designed to limit equally voltages of both polarities. In further variants, those high conductivity regions which lie in the major surface are replaced by Schottky barrier contacts.
