Filed: 1962-07-27
Abstract: 1,043,368. Packaging-machines. MOLINS ORGANISATION Ltd. July 26, 1963 [July 27, 1962], No. 28961/62. Heading B8C. [Also in Division A2] In apparatus for feeding cigarettes, the cigarettes are stacked in a hopper and a testing device periodically operates to detect faulty batches which are rejected by means responsive to the testing device. Cigarettes supplied to hopper 1 (Fig. 1) fall between vanes 5 and form a stack between walls 6, and are supported by movable rods 10. Two detector assemblies 14 (Fig. 2) are moved inwardly, allowing plungers 9 to engage the ends of the cigarettes in a batch so that the ends of the cigarettes abut plates 24. Electrical contacts are made to plates 18 and to collars 20 on shafts 17 of plungers 9, the shafts 17 passing through holes 18a in plate 18 across the support 16, so that movement of plungers 9 opens or closes the electrical circuit. As the assemblies move inwardly plungers 9 which are engaging cigarettes are moved relatively to the supports 16 against the action of springs 21 by the counter pressure exerted by each cigarette on its engaging plunger, thus moving collars 20 away from plate 18 to break the electrical circuit. If the batch is faulty the counter pressure of the cigarette is insufficient to move the plunger 9 so the circuit remains closed. Plate 18 and collars 20 are connected to a timed rejector means, which responsively rejects faulty batches. Supports 16 of assemblies 14 are attached to horizontal bars 25 (Fig. 3) and as cams 30 rotate bars 25 are moved alternately towards and away from each other by the combined action of cams 30 and springs 29, the movement being guided by rollers 27 on guides 26 which maintain bars 25 parallel to each other as they are moved towards or away from the stack of cigarettes during detecting operations. Cams 30 rotate in timed relationship with the movement of a conveyer chain 13a (Fig. 2) carrying pushers 12 which remove. a batch of cigarettes from the bottom of the stack while the detector means is acting on a group. The testing device is arranged to have a range of action such that a full complement of cigarettes tested in a single operation is a multiple of the number of articles required in a batch, whereby each batch is tested more than once. A modification is described where support rods 10 are omitted, the cigarettes being supported by projections engaging the cigarette end and the plungers 9 of the bottom row act only as yielding carriers for the members on which the projections are formed; thus in this construction less rows of cigarettes are tested at a time.

Title: Process for colouring acetate artificial silk
IPC: C09B3/06
Filed: 1935-10-30
Abstract: Cellulose acetate artificial silk is coloured yellow shades by applying to the material a Bzl-alkoxybenzanthrone wherein the alkoxy group has 2-5 carbon atoms and may itself carry a substituent, excluding a sulphonic or carboxylic acid group, which in the case where the substituent is an alkoxy group contains not more than 5 carbon atoms.  The alkoxy substituent may be the residue of a primary alcohol, for instance, ethoxy, n-propyloxy, n-butyloxy-, n-annyloxy-, or the residue of a secondary or tertiary alcohol such as isopropyloxy, isobutyloxy-, tert.-butyloxy, or b -chlor-ethoxy, b -oxyethoxy-, b -methoxyethoxy, b -ethoxyethoxy.  These derivatives are prepared by treating Bzl-oxybenzanthrone with alkyl esters of inorganic acids or of arylsulphonic acids.  In examples acetate artificial silk is dyed in an aqueous bath of Bzl-ethoxybenzanthrone or printed with a paste of Bzl-ethoxybenzanthrone, water, gum Senegal thickening and glycerol, dried, steamed at 100 DEG  C., and then washed.  Acetate artificial silk may similarly be dyed or printed with Bzl-b -chlorethoxybenzanthrone, Bzl-isopropyloxybenzanthrone, Bzl-n-butyloxybenzanthrone, Bzl-n-amyloxybenzanthrone, Bzl-b -methoxyethoxybenzanthrone, and Bzl-ethoxyethoxybenzanthrone.

Abstract: 966,204. Cleaning tubes. S.A. CHRISTENSEN & CO. A.S. Aug. 3, 1962, No. 29987/62. Heading F2N. In an apparatus for the automatic cleaning of a milk conveyer pipe 7 comprising a closed, cleaner-liquid container 1 which at the top thereof is connected with an air pipe 19 connected to a valve 16 controlled by the liquid level in the container, the arrangement being such that the container is connected to atmosphere when the level of the liquid is high and to vacuum when the level is low, the bottom of the container being provided with an outlet 2 for liquid, the container has at the top thereof an inlet connected to the pipe 7, and the outlet 2 has an outwardly opening, freely moving, valve body 5 disposed in a trough 3 located beneath the apparatus and into which extends one end of a suction line 8, the other end of which is connected to the pipe 7. As shown in Fig. 1, the cleaning liquid is carried in the trough 3, the buoyant valve 5 is in the outlet closing position and the float 9 carried by rod 10 is in the lowermost position thereof; the arm 26 of a two-way valve is positioned such that the branch 12 is connected to the branch 13, these branches being respectively connected to the bottom of the valve 16 and a vacuum tank 18, and the top of the valve 16, the top of the valve being thereby subjected to vacuum and thus being operated to allow vacuum to pass through the pipes 17 and 19 to the container 1, thereby causing the cleaner liquid in the trough 3 to be sucked through the pipe 8 and into the container. As the liquid level rises in the container the float 9 moves upwardly to move the valve 11 to a position whereby the branch 12 is connected to atmosphere, the influence of which operates the valve 16 to break the connection between the pipes 17 and 19 and to connect the pipe 19 to atmosphere. Air entering the container through pipe 19 causes the liquid therein to pass through the outlet 2 to the trough 3 so that the valve body 5 rises to close the outlet, the container again being subjected to vacuum. The cleaning cycle is repeated as long as is desired.

[Class 40 (v)] [See also Group XXXI] Electric power for propelling a vehicle is supplied thereto through an arc converter such as a rectifier or inverter, which is mounted on the vehicle and the electrodes of which are adapted to be swept by a stream of gas, wherein, upon failure of the normal supply of gas, the compressor of the pneumatic braking system is adapted automatically to supply air to the converter. A rectifier 1 is connected through a Venturi nozzle 5 to an air pump 7, which is driven by a motor 8, and through a master valve 11, reducing valve 13 and non- return valve 14, to an air reservoir 10. A compressor 16, driven by a motor 19, is connected through a non-return valve 18 to the brake reservoir 17 and through a non-return valve 15 to the reservoir 10. The power supply, through lines 20, to the motor 19 is controlled in dependence upon the pressure in the reservoir 17. An auxiliary power supply is adapted, through lines 26 and any of the switches 6, 9, 25 to energize a solenoid 12 to open the valve 11 and thus to connect the reservoir 10 to the rectifier, and further, to energize a winding 22 to control the auxiliary power supply, through lines 23 and switch 21, to the motor 19. The switch 6 is adapted to be closed by the Venturi nozzle 5 when the rate of flow of air in the pipe 4 reaches a predetermined minimum, the switch 9 closes when the speed of the motor 8, or alternatively the current therethrough reaches a prescribed value, and the switch 25 is adapted to be closed when the pressure in the reservoir 10 reaches a certain minimum value. An exciting electrode 3 is supplied with a potential, synchronous with that on the main electrodes, through a transformer 30. Pressureresponsive means 33 or 34 are adapted, when the air pressure in the reservoir 10, or in the supply pipe from the pump 7, reaches a minimum value, to open switches 31 or 32 respectively to break the supply circuit of the transformer 30 and thus to extinguish the converter ; alternatively, the said switches may be arranged in a circuit containing a breaker controlling the main supply to the rectifier. The pump 7 may be adapted to supply air to the motors driving the vehicle. Specifications 406,999, 409,974, and 412,935 are referred to.
