Title: Improved method and apparatus for handling biscuits and the like
Inventor: MORTON DAVID CHARLES
IPC: B65B35/40
Filed: 1958-10-17
Abstract: 873,337. Conveyers. PACKMAN MACHINERY Ltd. Sept. 25, 1959 [Oct. 17, 1958; Aug. 25, 1959], Nos. 33230/58 and 29081/59. Class 78 (1). Apparatus for removing metered batches of biscuits from an advancing column standing on edge comprises a transfer device 24 having teeth 25 which engage at least the rearmost biscuits of the batch and move these biscuits rearwardly as they are displaced from the column to increase their pitch to a value in excess of the average pitch of the biscuits in the column, means for withdrawing the displaced batches of biscuits in succession from the displacing device, and mechanism operative prior to displacement of each batch of biscuits to arrest and move bodily backwards biscuits situated in the column to the rear of and near to the batch to be separated. When the leading biscuit comes into contact with a stop 20 on the device 24, grippers 45 move inwardly to engage the biscuits in rear of the batch to be separated and then move rearwardly to establish a gap Y1 between the 17th and 16th biscuits. When this movement is completed, the rack 25 commences to move upwardly and the biscuits are lifted successively off the fixed track 35. As each biscuit is lifted it is shunted rearwardly to increase the pitch of the batch. As the rack rises its toe 23, Fig. 3, provides a support for the biscuits between the rack and the grippers and reduces the width of the gap between them from Y1, Fig. 2, to Y2, Fig. 3. A blast of air travelling in the direction of the arrow B, Fig. 4, maintains the biscuits in position on the rack. When the last biscuit has been raised above the rails 36, these rails move inwards to a position below the lifted batch and stops on the rails move into position to support the next batch. The rack is then lowered and the biscuits are deposited on the rails 36, Fig. 5, from which they are removed by a reciprocating plunger to a table along which they are moved by the flights of an intermittently moving endless conveyer.

Title: Manufacture and use of isopropyl-aryl compounds chlorinated in the isopropyl residue
IPC: C07C22/04
Filed: 1947-12-17
Abstract: Chloro-isopropylaryl compounds of formula CX2Cl.CRZ.CX2Cl, where R is aromatic which may be substituted by alkyl, alkoxy or halogen, Z is as R or is chlorine, and one or two of the groups X are chlorine and the rest are hydrogen, are prepared by treatment of a chlorinated acetone of formula CX2Cl.CO.CX2Cl with an aromatic compound RH in the presence of aluminium chloride.  With aromatic compounds such as benzene, ethylbenzene, chlorobenzene, or o-dichlorobenzene a product is usually formed in which Z is chlorine; when the aromatic compound is, e.g., o-xylene, naphthalene or anisole, Z in the product is usually the same as R.  The chlorinated acetone may be a mixture of isomers.  The reaction temperature is low, e.g., in the range - 15 DEG  C. to + 5 DEG  C.  In the examples, in all of which aluminium chloride is used, (1) 1 : 1 : 3-trichloroacetone is treated with chlorobenzene to give tetrachloroisopropyl - p - chlorobenzene; 1 : 1 : 3 : 3 - tetrachloroacetone is treated with, (2) chlorobenzene to give symmetrical pentachloroisopropyl-p-chlorobenzene; (4) toluene to give pentachloroisopropyltoluene; (5) and (6) anisole to give pentachloroisopropylanisole; and (7) a -chloronaphthalene to give pentachloroisopropyl-a -chloronaphthalene; and (3) 1 : 1 : 1 : 3-tetrachloroacetone is treated with chlorobenzene to give asymmetrical pentachloroisopropyl - p - chlorobenzene.  The Specification as open to inspection under Sect. 91 comprises also the compound 2 : 4-dichlorotoluene as a suitable aromatic compound, and states that pentachloroisopropyl-p-chlorobenzene treated with alkali gives tetrachloroisopropenyl - p - chlorobenzene.  This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for Measuring Gas Flow
IPC: G01F1/50
Filed: 1967-07-24
Abstract: 1,153,105. Measuring gas flow. FOXBORO CO. July 24, 1967 [Aug.9, 1966], No.33988/67. Heading G1R. Apparatus for measuring the flow of gas and for producing a signal corresponding to the measured flow comprises means such as an orifice in the gas stream 10 to produce a pressure drop and a differential pressure signal corresponding thereto, a pressure cell 16 responsive to said differential pressure to produce a force signal which acts on a force bar 18 and sensing means responsive to a characteristic of the gas such as static pressure or density for producing a second force signal proportional to the value of said characteristic. The apparatus also comprises a mechanism 20 for producing an intermediate signal representing the product of the two force signals, the mechanism comprising a first balanceable member 26 connected to the force bar which transmits the first force signal to the member 26, a reaction element 42 connected by flexures 36, 32 and 48 to member 26 to control the movement of the balanceable member 26. Force is applied to member 26 by means of bellows 50 and to reaction element or yoke 42 by means of bellows 54. The force applied to yoke 42 is dependent on the characteristic of the gas such as static pressure so that the force applied to the yoke adjusts the movement of the member 26. A detection nozzle 52 detects movement of the member 26 and passes a signal through a relay to cause a rebalance force to be applied through bellows 50, said rebalance signal serving as said intermediate signal. A second mechanism 22 serves to produce a final output signal corresponding to a square root function of the quantity represented by the intermediate signal, the final output signal being linearly related to the gas flow-rate. The mechanism comprises a balanceable member 26a and a reaction element 42a connected by flexures, force being applied to balanceable member 26a by means of lever 66 and nozzle 50a and to reaction element 42a by nozzle 54a. A detector nozzle 74 feeds back the position of member 26a to a relay which produces a rebalance signal corresponding to an unbalance of the member 26a. The intermediate signal is transmitted to nozzle 50a and the rebalance signal to lever 66 and nozzle 54a via line 80. This second rebalance signal thus provides the final output signal.
