Title: Apparatus for feeding sweets or articles for wrapping
Inventor: SCHMITZ HEINZ
IPC: B65B35/14
Filed: 1965-11-17
Abstract: 1,120,173. Wrapping m/c feeding apparatus; conveyors. F. THEEGARTEN. 17 Nov., 1965, No. 48839/65. Headings B8A and B8C. An apparatus for feeding rectangular sweets 14 to a wrapping machine comprises a vibratory conveyer 24 which serves to align the longitudinal axis of the sweets in the direction of conveyance. The sweets, 14 are fed from a hopper 13 on to a vibratory conveyer 21 which consists of eight individual channels arranged side by side, each resting on a pair of supporting springs 22 and each driven by an electrical vibratory drive 23. Above the conveyer 21 a brush 19 is provided to prevent sweets being fed along the conveyer one on top of another. The sweets, 14 are then fed on to the vibratory conveyer 24, which similarly consists of eight individual channels which are each driven by an electrical vibratory drive 26. The vibrations of the conveyer 21 are stopped for short periods of time in order to stop the flow of sweets, 14, on to the conveyer 24. This allows the sweets, 14 on the conveyer 24 to be spaced from each other and hence align themselves longitudinally in the channels. Alternatively, the conveyer 21 may operate at a slower rate than the conveyer 24. The sweets, 14 then pass on to a third vibratory conveyer 27. The conveyer 27 consists of a plate 28 which is divided into eight channels by plates (30), Fig. 3 (not shown). The vibratory conveyer 27 is driven by a single drive 34. Mounted above each of the channels of the conveyer 27 is a feeler 35 which operates a time switch 36. Each feeler 35 is raised as a sweet 14 passes through the channel beneath it. If a feeler 35 is raised for longer than a predetermined time, the switch 36 operates a time switch which stops the conveyers 21, 24. The conveyer 27 continues to operate and moves the sweets 14 to a pair of belt conveyers 31, 32 which feed the sweets, &c. into channels (15), (16), Fig. 4 (not shown). The upper belt 31, Fig. 1, is biased by springs 30 against the belt 32. The channels (15), (16), Fig. 4 (not shown), feed the sweets on to slides 17, Fig. 1, above an allocating plate 11. When the slides 17 are removed, plungers 18 push the sweets 14 into pockets (12) Fig. 4 (not shown), on the plate 11.

Abstract: 1434020 Sulphonation of aromatic compounds A KOEBNER 24 Oct 1973 [30 Oct 1972] 49509/73 Divided out of 1434019 Heading C2C A process for the sulphonation of aromatic substances comprising one or more aromatic compounds containing at least one -CH= group and susceptible to the direct action of sulphur trioxide to yield a product having a sulphonated aromatic nucleus, but otherwise substantially inert under the reaction conditions to sulphur trioxide, wherein:-(1) said aromatic substance is admixed with an organic material substantially inert to the action of sulphur trioxide under the reaction conditions to be employed, so as to form a reactant which, at a temperature of 100‹ C. or below, forms a solution or suspension which boils at a temperature of 100‹ C. or below under a pressure of 0À1 mm. Hg; (2) said reactant is brought to boiling in a reaction chamber at a temperature of 100‹ C. or below under a pressure of from 0À1 mm. Hg to atmospheric pressure; (3) gaseous sulphur trioxide is introduced into the boiling liquid mixture within the reaction chamber to react exothermically with the aromatic substance, heat liberated in the exothermic sulphonation reaction causing the mixture to continue to boil and furnishing the latent heat of volatilization of the matter that volatilizes; (4) the matter thus volatilized is reconverted to liquid in a heat-exchanger, so that the latent heat of volatilization is given up in the heatexchanger and heat liberated in the sulphonation reaction is thus removed from the reaction chamber; (5) the volatilized matter reconverted to liquid in the heat exchanger is recycled to the reaction chamber; and (6) the pressure in the reaction chamber and the rate at which the gaseous sulphur trioxide is introduced into the mixture within the reaction chamber are so controlled that matter is volatilized, reconverted to the liquid state and recycled to the reaction chamber at such a rate as to ensure that there is always present in the mixture within the reaction chamber an amount of volatilizable matter exceeding that amount capable of being volatilized by the heat of reaction of the aromatic substance present with the gaseous sulphur trioxide in contact with said aromatic substance in the reaction chamber and that the temperature of the mixture is a temperature of 100‹ C. or below. Many sulphonatable aromatic compounds are specified, including benzene, naphthalene, anthracene, indane and thiophene compounds. Many organic substances, acting as solvents, are specified including aromatic substances which may themselves be sulphonated by the process but which sulphonate only slowly. The process may be carried out continuously, involving separating both unreacted aromatic substance and inert organic material from the sulphonated aromatic substance and purifying the former and recycling them to the process. A separate apparatus is described for each of batchwise and continuous processes.

In a cigarette lighter action, an outer actuating member part 33, e.g. of embellished metal, is provided with depressions 34 which engage complementary shoulders 35 on an inner plastics actuating member part 4 so that it may be snapped thereover to conceal the action and, in use, to transmit thumb-pressure thereto. The inner part 4 is pivoted at 6, 7 to a plastics intermediate member 5, e.g. a snuffer cap, having downwardly depending legs 10 pivoted together with an associated pawl disc and a flint wheel 12 and its associated ratchet, on an axle 9 passing through upstanding legs 11 on a plastics action carrier 3, the other end of part 4 having a cam follower surface 18 guided downwards and away from the flint wheel by a cam surface 19 on the carrier 3 when in operation to rotate the wheel 12 against an upwardly urged flint in a tube 24. The arrangement of the pivotal axes of the pivots 6 and 9 gives an over dead centre snap action and the cam surfaces 18, 19 also give a snap action. A return spring 20 has its ends secured on integral anchorages 21, 22 on the inner actuating part 4 and the carrier 3 respectively and the inactive position is reached when the legs 10 abut stops 23 on the carrier and shoulders 15 on a pair of legs 13 on the inner part 4 abut complementary shoulders 17 on the carrier. The shoulders 15 are formed with a chamfer 14 to facilitate assembly. A fuel reservoir 26 is fitted so that the flint tube extends through a passage 28 therein and a burner, e.g. for gas, extends through an aperture 25 in the carrier. The burner has a valve actuated by rocking of a lever 30 by depression of the inner actuating part 4. An outer embellished metal shell 31 is slid over the action and holds the pin 9 in place. In a modification, Fig. 3 (not shown), the pivot between the part 4 and the intermediate member 5 comprises a cylindrical rod integral with part 4 snapped into a cylindrical slot in member 5. The part 4 is guided at its other end by being pivoted to the legs of a yoke pivoted on the carrier 3.

[Class 135] In relays for indirectly-acting constant-value regulators having variable leverage of a spring and /or of the regulating impulse on a movable member, the latter engages directly, and the former either directly or through an adjustable slider. The variation is effected in various ways. The invention is described as applied to a movable jet-tube 4 delivering variably to conduits 7, 8. In Fig. 1 the spring 10 is fixed, while the point of application of the impulses of a sensitive diaphragm 2 is varied by adjusting its height on a guide rail 11. Alternatively the diaphragm may be fixed and the spring mounted on a guide rail, either vertical or inclined. In Fig. 4 the spring 10 is attached to a pivoted rod 18 connected to a cam 22 by which a slider 12 of known type is caused to vary the mechanical relation between the tube and a pivoted rod J acted on by the spring; in a non-automatic form the slider and the tension of the spring are adjusted manually. Other relays such as a control piston can be substituted for the jet 4. In Fig. 8 is shown the application of the invention to fuel regulation for steam boilers according to load. A bellows 25 is connected to a pivoted lever 27 which bears against a tube 4, and a servo-piston 29 is connected to a valve in the fuel pipe 23 and to a lever 31 which controls a cam 33 as shown in Fig. 4. The residual force of the spring 10 which remains at the smallest adjustment value of the slider 12 may be calibrated to a weight 28 which is in equilibrium with the steam pressure.
