Title: Improvements in the manipulation of labels in labelling machines
Inventor: ROSE ALFRED GERMAN
IPC: B65C9/08
Filed: 1952-02-02
Abstract: 723,131. Labelling machines. ROSE BROS. (GAINSBOROUGH) Ltd. March 27, 1953 [Feb. 2, 1952 ; March 6, 1952], Nos. 2822/52 and 5811/52. Class 73. [Also in Group XVI] In a labelling machine the labels are separated in succession from a stack 13, Fig. 1, in a magazine 14 by a number of suction separators 12 (see Group XVI) which are carried by a common rotatable support 11, each label having gum applied thereto by a gumming-apparatus 16, and then being carried to a station at which a continuously-moving conveyer 17 moves a succession of round bottles 18, spaced by a rotating worm 19, into register with the separators. Each bottle is pressed against a separator 12 by a wheel 21 which rotates in a direction opposite to that of the support 11, so that the bottle is caused to roll on the label, the suction to the separator being cut off just prior to this rolling action. Further rolling pressure is applied to the labels on the bottles by a driven belt 22 mounted on pulleys 23, '24, the inner lap of the belt being spring-urged towards the bottles by a pressure-plate 26. The wheel 21 is mounted on a pivoted arm 68 urged by a spring 69 towards the conveyer 17. In a modification, shown in Fig. 7, the labels are applied to bottles with flat sides. The magazine 73, the rotatable support 71 carrying suction separators 72, and gumming-apparatus 74 are the same as before, but as rotatable worm 78, which spaces bottles 77 on a continuously-moving conveyer 76, is extended past the nip of a pressure wheel 79 so as positively to maintain the spacing of the bottles until registration has taken place. The wheel 79 is pivoted on a spring-urged arm, but is rotated in the same direction and at the same peripheral speed as the support 71, so that the label is transferred to the flat side of the bottle by the separator 12 rolling over that side. The wheel 79 comprises two spaced discs between which the worm 78 extends. Additional pressure on the labels on the bottles is applied by a driven resilient band 82, the inner lap of which is urged towards the bottles by a spring-loaded plate 83. In each case the gumming-apparatus 16 or 74 may be dispensed with, the labels having a prepared surface which is rendered adhesive by heat, and either heaters are incorporated in the separators 12 or 72, or the latter pass close to a source of heat, whereby the labels are rendered adhesive during their travel between the stack and the labelling station.

Title: Improvements in or relating to the method of preparing beta-acyloxy carboxylic acidsand their anhydrides
IPC: C07C69/22
Filed: 1950-02-08
Abstract: Saturated aliphatic b -lactones are reacted with carboxylic acids or the corresponding anhydrides in the presence of a mineral acid catalyst to give beta-acyloxy carboxylic acids when carboxylic acids are used and betaacyloxy carboxylic anhydrides, which are claimed as novel, when the anhydrides are used. Suitable mineral acid catalysts are sulphuric, hydrochloric, nitric and phosphoric acids, which are preferably present in an amount of 0.01-1 per cent by weight of total reactants. Saturated and unsaturated, aliphatic and aromatic, mono- and polycarboxylic acids or their anhydrides may be used, e.g. acetic, propionic, butyric, isobutyric, caprylic, caproic, capric, lauric, palmitic, stearic, acrylic, crotonic, oleic, linoleic, cyclohexanoic, furoic, benzoic, toluic, cinnamic, oxalic, succinic, adipic, sebacic, aconitic, maleic and phthalic acids or their anhydrides may be used.  The acids or anhydrides may have as substituents halogen, nitro, oxy, hydroxy, thio, thiol, cyano, acyl, acyloxy, keto, amino and azo groups.  Suitable saturated beta-lactones are beta-propiolactone, beta - butyrolactone, beta - isobutyrolactone, beta - valerolactone, beta - isovalerolactone, beta - n - caprolactone, alpha - ethyl - beta - propiolactone, alpha - methyl - beta - butyrolactone and beta-methyl-beta-valerolactone.  In the examples: (a) beta-propiolactone is reacted with acetic anhydride in the presence of sulphuric acid to give beta-acetoxy propionic anhydride which on refluxing with ethyl alcohol gives 1-ethyl beta-acetoxy propionate and betaacetoxy propionic acid; (b) beta-propiolactone is reacted with glacial acetic acid in the presence of sulphuric acid to give beta-acetoxypropionic acid; and (c) beta-propiolactone is reacted with propionic acid in the presence of sulphuric acid to give beta propionoxy-propionic acid.

Title: Improvements in and relating to lanterns for electric lamps
IPC: F21V19/02

The latter is adjustable vertically by means of an extension 6 pinned to a rod 5 which is free to rotate in a boss 4 on a cap 3, the rod 5 being fitted with a locating collar 9 and having its lower end screwed into the member 8. Horizontal adjustment is effected by means of a slight tilting movement of the holder 19 when the member 18 is released from the limbs 8, 16 which are attached to each other by a pin 17. This release, and the subsequent relocking, is effected by means of an extension 12 pinned to a rod 10 which is free to rotate in a boss 11 on the cap 3, the rod 10 being fitted with a locating pin 14 and having its lower end made square or otherwise made slidable but not rotatable in a sleeve 15 which is free to rotate in the limb 16 but is screwed into the limb 8.

Title: Improvements in or relating to beam forming apparatus
Inventor: RICKETTS LUTHER W JR
IPC: G01S1/72
Filed: 1967-01-24
Abstract: 1,173,365. Direction finding. MAGNAVOX CO. 24 Jan., 1967, No. 3458/67. Heading H4D. In a system for determining from which of q directions a vibrational energy beam is received, the outputs of n receiving transducers in a fixed array are all sampled to give a set of n binary " bits " which are stored as a " word " in a memory, the sampling is repeated p times at delay intervals and the resulting p stored words are then read out separately to a register having n outputs coupled through a distributing network to q accumulators respectively associated with the q directions, the network being such that each accumulator receives a total of n bits, the bits being only from those words associated with delay intervals corresponding to the delays which would be necessary to give co-phasal outputs from the transducers for the respective beam direction. As applied to an exemplary four-transducer array 51, 52, 53, 54 the sampling is done by a zero-crossing detector and is at intervals T equal to the sound propagation time between a transducer and the array centre. Three words are stored serially in rows 1 to 3 of a magnetic core memory 64 whose columns are allocated to respective transducers. The words are then brought down separately to sense register 59 and the bits are applied to gates 67 to 71. For a beam incident along line 51-54 (beam 1) co-phasal transducer outputs are obtained if 54 output is undelayed, 52 and 53 outputs are delayed by T, and 51 output is delayed 2T, so that the bits to be distributed to the accumulator for beam 1 are from column 4 first word, columns 2 and 3 second word, and column 1 third word. The distribution is achieved by selectively opening the gates with pulses from a scan counter 66. Further gates and accumulators are provided for other beams. After each word has been brought down to register 59 it is rewritten into its original memory address, with the exception of the oldest word. To permit updating of the transducer data the oldest word is replaced once in each complete cycle of scan ounter 66 by a fresh sample word, the addressing (reading) of the memory being precessed to preserve the sequence in which words are brought down to register 59. Details of a further embodiment (Fig. 4, not shown), in which n = 30, p = 25 and q = 30, are given. It is shown also that for beam directions symmetrical with respect to the transducer array, periodicity exists in the order in which memory bits are distributed to the relevant accumulators, permitting a commutator to be used in place of a large number of gates in the distributing network. Details of such a commutator are given (Figs. 17, 20-23, none shown).
