Title: Improvements in and relating to bag filling and weighing machines
IPC: B65B1/18
Filed: 1930-04-02
Abstract: 347,446. Weighing-apparatus. JOHNS, H. S., of Crystalite Stone Products, Hillyard Street, Hamilton, Ontario, Canada. April 2, 1930, No. 10422. [Class 143.] A bag-filling and weighing machine comprises a material-containing hopper having a nozzle projecting therefrom into the bag and a screw conveyer extending across the bottom of the hopper and attached by a flexible coupling to a drive shaft supported by the hopper, the external diameter of the screw-conveyer being somewhat less than the internal diameter of the nozzle so that in operation the free end of the screw conveyer may be supported and centred by the material being delivered through the nozzle. The screw conveyer 12, Fig. 6, is attached by a flexible coupling 101 to a shaft 99 connected to an electric motor. The nozzle 9 and the casing 90 below the screw conveyer may be detached to permit of the substitution of a nozzle and conveyer of different dimensions. The platform of the weighing scale supports a frame 3 bearing a pivoted bag support 6 which is held, at the commencement of a weighing operation, in the titled position shown, by means of a toggle lever 18 supported on a spring 27. The height of the bag support and the position of its sides and back may be adjusted to suit bags of various capacities. In using the apparatus, an empty bag is placed on the bag support 6, with the nozzle inserted into the upper corner of the bag, and the motor is started thereby delivering material into the bag. As the bag fills, its weight overcomes the resistance of the spring 27 and the bag swings towards the vertical position thereby raising the bag above the nozzle and avoiding undesirable pressure thereon. When the weight is completed the movement of the weighing scale cuts off the motor current and stops the feed. Upon breaking the toggle lever 18 the bag support 6 swings downward and tips the filled bag on to a bench or conveyer belt. If the material sticks in the hopper, the shortage of material supporting the screw conveyer causes the conveyer to vibrate and shake down the sticking material.

Patent GB-106881-A (GB)
IPC: G06C11/02
Abstract: 106,881. Field, R. June 21, 1916. Cash registers with operating-means.-A cash register having indicators as described in Specification 22265/13 is provided with a totalizer, the differential mechanism for which is set from the indicator rods, and the actuating parts of which are operated by staggered cams for each lever-key, commencing from the highest values, so that a number of keys may be depressed simultaneously. In the pence bank, levers are provided for one, two, three, and six pence, and in the unit of shillings bank, levers are provided for one and two shillings and their slotted levers carry three tumbler levers which may be successively brought into action by depressing the keys three times. Movement of the handle P in the direction of the arrow R, Fig. 1, unlocks the keys and depression of key B releases the indicator mechanism, and the movement of the operating handle P in the reverse direction sets the indicators and thereby rocks slotted levers j carrying tumblers l which move idly past pawl-carrying arms n engaging the totalizer wheels f. The depression of a key withdraws a slide F from a projection H on the indicator rod T and throws a slide G into position to engage the projection; on the return of the key under spring action, the slide G is withdrawn and the slide F replaced to engage the next projection on the rod I which thus completes one step of its movement. When the handle is next operated prior to a fresh operation of the machine, the tumbler l moves the arms n in turn and thus actuates the totalizer wheels. The pence totalizer wheels c are mounted upon a shaft a provided with a total-indicating wheel upon which four sets of numerals are arranged; the half-pence wheel c transfers at every alternate movement and is connected to a rocking indicating sector a; while the shillings levers actuate totalizer wheels f and the tens-of-shillings lever actuates a wheel f that transfers at each alternate movement to the pounds counter h. Transfer mechanism.-A series of abutments 3 in the unit of shillings wheel g, Fig. 5, engage a pin 2 and rock an arm z carrying a pawl 4 which transfers on to the tens-of-shillings wheel w ; pins 5 projecting from this wheel operate the star-wheel 9 of the pounds counter at each alternate stroke. The transfer from pence to shillings is externally operated and is set by abutments 10, Fig. 4, upon the pence wheel that engage a weighted arm 11 and set an arm 34 which carries a bell-crank extension 15 adapted to engage the pawl-carrying arm n for the shillings wheel. A wiper 19 on the operating shaft O moves idly past a tumbler 20 upon a lever 17 in one direction, and on its return tilts the lever and thus acts on the arm 14 to effect transfer.

Patent GB-409131-A (GB)
Title: Method of carrying out the friedel-crafts reaction
IPC: C07C37/18
Filed: 1933-04-18
Abstract: Aliphatic groups (including acidyl groups and aralkyl groups) are introduced into the nuclei of organic compounds having an aromatic nucleus by reacting the said compounds with a halide of the aliphatic group in the presence of hydrated ferric chloride. Suitable aromatic compounds are aromatic hydrocarbons, e.g. benzene, toluene, xylene and naphthalene, and their nuclear substitution products, e.g. amino, halogen (e.g. chloro) or carboxylic derivatives, and particularly aromatic compounds having nuclear hydroxy groups such as phenols, e.g. phenol or cresols, and naphthols.  Suitable aliphatic halides are halogenated aliphatic hydrocarbons, e.g. methyl, ethyl, propyl, butyl and amyl chlorides, bromides or iodides, benzyl chloride, vinyl chloride, methylene chloride and chloroform, and acid chlorides, e.g. acetyl chloride.  The reaction of vinyl halides with aromatic hydroxy compounds, however, is disclaimed.  The reaction may be carried out by heating the reagents and catalyst together under reflux, or by heating the ferric chloride with the aromatic compound and slowly running in the aliphatic halide.  In examples: (1) phenol, tertiary butyl chloride and hydrated ferric chloride are heated to 80--90 DEG C. and the reaction mixture is poured into water whereby crystals of tertiary butyl phenol separate; (2) the tertiary butyl chloride is replaced by tertiary amyl chloride, yielding tertiary amyl phenol. Specification 409,132 is referred to.
