Title: Apparatus for detecting cocked closure caps on containers
IPC: B65B57/04
Filed: 1965-01-20
Abstract: 1,086,366. Stoppering; conveyers &c. ANCHOR HOCKING GLASS CORPORATION. Jan. 20, 1965 [Jan. 20, 1964], No. 2515/65. Headings B8A and B8T. Containers 5a with closure caps 3a which have not been properly applied are removed from a conveyer 4 of capped containers by apparatus including a detecting mechanism 1 which operates an electric switch when a faulty capped container is detected, and causes a solenoid operated cam 20, Fig. 7, to move one of a series of pins 29a on a memory wheel 22 to an extended position. The wheel and conveyer are driven in synchronism, so that when the faulty container has past the detector and has reached a position in front of a pusher rod 19 of an ejector unit 8, the extended pin 29a on the wheel strikes a switch arm 30. This operates an air motor which drives the pusher rod forward to push the faulty container from the conveyer. The detector mechanism includes pins 6, 11a which bear down on a " floating " shoe 152 supported by rails 151. The shoe responds to the position of a closure cap on a container conveyed below it. An improperly positioned cap will raise the fingers thereby allowing movement of an arm 14 which operates the electric switch. A dog 33 strikes any extended pins to return them to their original retracted position. When the caps are screw caps the detecting mechanism may be positioned before or after the final sealing operation. In a modification the detecting mechanism is associated with a rotary sealing machine having a peripherally pocketed star wheel 51, Fig. 8, (not shown), to receive the capped containers. A detecting unit 54 detects a faulty container, a memory unit 100 stores this fact, and when that container is moved in front of an air ejection nozzle 91 the unit 100 causes the operation of the nozzle to remove the container. The detection unit, Fig. 12, (not shown), includes a hollow spindle 55 slidably mounted in fixed supports 57, 57a, and a shaft 70 movable axially therethrough and supported by a spring 71. The lower ends of the shaft and spindle are loosely attached to a plate 60 and the arrangement is such that when a faulty container passes beneath the plate the latter is tilted, the shaft moves axially downwardly relative the spindle and electric contacts 84, 85 are engaged; one of a series of peripherally located pins in a memory wheel, synchronized with the star wheel, is extended by a cam. The extended pin eventually actuates a switch to operate the ejector nozzle. A timing switch adjacent the memory wheel is in circuit with the detection switch and ensures that a pin in the memory wheel will be extended only when a container is located centrally in relation to the plate 60. If there is no container below the detector unit the parts 60, 55 and 57 are lowered and a further switch is operated to stop the machine.

Title: Improvements in or relating to machines for pasteurizing dairy or other plastic edible products
IPC: A01J27/04
Filed: 1931-01-29
Abstract: Apparatus for pasteurizing and homogenizing plastic dairy products such as cheese and butter or other plastic edible products consists of means for feeding the product along a predetermined path and means in said path for frictionally producing heat of pasteurization by acting on the product.  In the construction described, the product, e.g. cheese, is fed from a receptacle 87 to a housing 15 where a screw conveyer 14<1> feeds it forward through an apertured plate 28, which comminutes it, into a cylindrical part 22 of a housing 20.  The cheese is carried by a screw 38 to between a conical member 53 rotating with screw 38 and a fixed conical portion 23 of the housing 20 and is there subjected to pressure resulting in the frictional production of the heat required for pasteurization.  The screw 38 and conical member 53 are carried by a shaft 39 which can be adjusted axially by screws 57, 61 operated by wheels 58, 65 and having lock nuts 59, 70, to allow the distance between the conical members to be altered, thus controlling the temperature to which the cheese is raised on passing therebetween.  The portion 23 of the housing 20 has a jacket 80 provided with connections to a hot-water supply for warming the apparatus when beginning operations to take off the initial chill, and a cold-water supply for regulating and controlling the maximum temperature to which the cheese is raised.  The housing 20 has a detachable end closure 47 with an annular channel 75 into which the pasteurized cheese is discharged with the aid of expelling members 72 attached to member 53.  The cheese passes to an outlet spout 78 having <PICT:0378376/III/1> <PICT:0378376/III/2> <PICT:0378376/III/3> <PICT:0378376/III/4> a slidable or other adjustable closure 79 to control the flow therefrom, and a thermometer 86.  The jacket 23 has a thermometer 85.  The apparatus is actuated by an electric motor 92 which rotates through gears 94, 95, shaft 96, sprocket wheel 100, chain 101 and sprocket wheel 102 a shaft 39<1> which is detachably connected by a flanged hub 66, Fig. 6, locked thereto by a screw 67, and pins 68 to the screw 38.  The pins 68 allow axial movement between the screw 38 and the shaft 39<1> during adjustment of the distance between the conical members but transmit rotary motion to the screw 38, and through it to the shaft 39 and member 53.  The screw 14<1> is driven from shaft 39<1> through a chain 108 rotating a shaft 103 connected through gear 109, 110 to the shaft 14 of screw 14<1>.  Water can be supplied to the material, e.g. to prevent scorching during treatment, from a tank 111 through a pipe 114 and valve 116.  The apparatus is used in the process of Specification 378,374 and for obtaining the product of Specification 378,375.  Specifications 278,653, [Class 49, Food &c.], and 327,808, [Class 81 (i), Disinfecting &c.], also are referred to.

Title: Improvements in or relating to commutators
IPC: H02K13/04
Filed: 1951-02-07
Abstract: 677,707. Making commutators. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Feb. 7, 1951 [March 17, 1950], No. 2983/51. Classes 83 (ii) and 83 (iv). A process of making a commutator and securing it to the armature coil-ends of a dynamo-electric machine comprises clamping together an assembly of copper and unhardened mica segments, heating said assembly, mainly from the inside, to a commutator-seasoning temperature, cooling and assembling the seasoned commutator on the armature and soldering the ends of the armature coils to the copper segments, the seasoning temperature being at least as high as the soldering temperature. A dynamo-electric machine comprises a stator 1, a rotor 2 on a shaft 3, an armature core 4, armature windings 5 and a commutator 6. The commutator comprises copper segments 10 separated by mica segments 11 and having necks 12 to which are soldered the coil-ends 13. The two ends of the commutator assembly have V-grooves 14 for receiving clamps 15 and 16 drawn together by bolts 17. Insulating V-ring members 18 are disposed between the segments and the clamps. For seasoning, the assembled commutator segments are squeezed together by an inner split clamp 22 and an outer solid clamp 23. A heatinsulating layer 24 is interposed between the clamp 22 and the segments. The clamped commutator is placed in a pan 28 supported in a solder pot 26 containing molten solder 27, the level of which can be raised or lowered. The bottom of the pan has an opening 30, and a yieldable heat-resistant gas jet 31 surrounding the opening provides a fluid-tight joint between the commutator and the pan. The solder level, which is initially below the bottom of the pan, is raised to immerse the interior of the commutator assembly to effect the seasoning, after which the clamping rings 21 are retightened and the assembly allowed to cool. The V-grooves 14 and the current-collecting surface 7 are then machined to final dimensions. If the bore had been machined prior to seasoning it is painted with a mixture of clay and water to prevent adhesion of solder to the bore. The seasoned assembly is mounted on the clamping V-rings 15 and 16 which are carried by a sleeve 33 which supports the armature-core 4. The coil ends 13 are then connected to the necks 12 of the respective copper segments 10 by placing the commutator end of the machine in a solder pot 36, Fig. 3. This pot has a cup 37 which surrounds the commutator but leaves the necks 12 exposed. An asbestos sealing ring 38 ensures a fluid-tight joint between the necks 12 and the cup 37. The solder level is raised in the pot 36 until the necks 12 are immersed to effect the soldering together of the necks and the coil ends. High temperature solder is used for both seasoning and soldering, the solder pot temperature being approximately 476‹ C. and the commutator segments reach a temperature of from 300‹ to 350‹ C. Liquids, other than solder, may be used in the seasoning operation.

Title: Improvements in or relating to time bases for the electro-magnetic deflection of electron beams
IPC: H03K4/26
Filed: 1949-02-03
Abstract: 657,431. Saw-tooth generating circuits. CINEMA-TELEVISION, Ltd., and McCONNELL, E. D. Feb. 3, 1949, No. 3014. [Class 40 (vi)] In a saw-tooth current generator of a type in which the magnitude of the current at the beginning and end of the scan changes with variations of the amplitude of the flyback stroke caused by inaccurate triggering due for example to noise accompanying the synchronizing pulses, the scanning strokes are corrected by varying the rate of scanning in dependence upon the amplitude of the preceding flyback stroke. The rise of current through a valve 9 and the output coil 14 which produces the scanning stroke is terminated by a positive synchronizing pulse Vg3 applied to terminals 1 to render a valve 3 conducting and so cut off valve 9. The energy stored in the output coil then executes a half cycle of oscillation to produce the flyback and the first part of the succeeding scanning stroke is produced by current from the inductor flowing through a damping valve 17. If the synchronizing pulse occurs too early (e.g. after a time T - t) the voltage pulse g across the output coil is smaller because the output current 113 has not risen to such a high value. The pulses however are applied to a peak rectifier 22, the output (Va22) of which is amplified and phase reversed by a valve 23. The sawtooth component of the output from this valve is balanced out by an opposite saw-tooth voltage applied to terminals 32, leaving a negative pulse which is applied to the grid of the damping valve to reduce the rate of rise of the output current from kl to km so that the desired peak output current is not reached until the next synchronizing pulse arrives. Negative feed-back is applied to valve 9 by connecting the resistor 7 to a small resistor 18 in the anode circuit of valve 17 and non- linearity due to the resistance of the output circuit is prevented by applying a correcting saw-tooth voltage to the grid of valve 17 as illustrated in Fig. 1 (not shown), and fully described with reference to a similar circuit in Specification 512,519. In order to avoid errors due to slow periodic variations of the synchronizing signals the coupling elements in the control circuit are such that they do not pass these slow variations.
