Patent GB-1597017-A (GB)
Title: Apparatus for printing and dispensing labels
IPC: B41K5/00
Filed: 1978-05-23
Abstract: A label applicator for printing and applying the printed labels. The applicator includes a manually-actuated handle (16) pivoted to a frame of the machine serves to actuate a linkage (28) which in conjunction with a bell-crank lever moves a print head into engagement with a label on the platen. The linkage (28) and bell-crank levers (30) serve to produce a toggle action so that even with stamp-impression printing, the printing force applied is the same irrespective of the pressure applied to the movable handle. The applicator can be used wherever high quality printing on labels is required.

Title: Improvements in and relating to the production of nonyl alcohols
Inventor: DEAN FRED
IPC: C07C29/16
Filed: 1950-08-31
Abstract: The phthalates of 3.4.4-, 3.4.5- and 4.5.5-trimethylhexanol-1 are used as plasticizers for polyvinyl chloride.ALSO:The invention comprises the new compounds 3, 4, 4-trimethylhexanol-1, 3, 4, 5-trimethylhexanol-1 and 4, 5, 5-trimethylhexanol-1.  In particular trimethylhexanols-1 in which the three methyl groups are attached to two or three consecutive carbon atoms are prepared by reacting trimethylpentenes-1 or -2, in which the three methyl groups are in 2, 3, 3-, 2, 3, 4- or 3, 4, 4-positions, with hydrogen and carbon monoxide in the presence of cobalt as catalyst in the liquid phase, under superatmospheric pressure and at elevated temperature, and hydrogenating the resulting aldehydes.  The resulting alcohols may be separated by fractional distillation.  Suitable hydrocarbons to be used as starting materials are 3, 4, 4-trimethyl-pentene-1, 3, 4, 4,-trimethylpentene-2, 2, 3, 4-trimethyl pentene-1, 2, 3, 4-trimethylpentene-2 and 2, 3, 3-trimethylpentene-1.  A suitable catalyst for the hydrogenation step is copper-on-zinc oxide or copper-on-chromia and it is preferred to decompose metal carbonyl and expel carbon monoxide from the carbonylation product, e.g. by treatment with hydrogen, before carrying out the hydrogenation to aldehydes.  In the carbonylation step it is preferred to use a soluble cobalt catalyst such as cobalt naphthenate, acetate, hexahydrobenzoate or trimethyl hexoate.  Suitable reaction conditions for the carbonylation are a temperature of 130 DEG  to 190 DEG C. and 200-300 atm. pressure.  To produce the alcohols in pure form the individual octane fractions may be separated by distillation from a mixture obtained, for example, by cracking petroleum or by dimerisation of lower olefines obtained by dehydrogenation of paraffin, before the carbonylation step. Alternatively mixed olefines may be used and the resulting mixture of alcohols separated by distillation.  The alcohols may be used as anti-foaming agents and as intermediates for the production of plasticizer esters, the corresponding octadecanols, thiocyanates, ethers and amines.  Esters such as sebacates, adipates and maleates may be produced from these alcohols and are useful as plasticizers and synthetic lubricants. The phthalates, which are useful as plasticizers for polyvinyl chloride may be prepared by standard methods.  In the example a fraction rich in 3. 4. 4-trimethylpentene-2 obtained by fractional distillation of C8 H16 hydrocarbons produced by dimerisation of dehydrogenated mixed butanes is heated with carbon monoxide and hydrogen in the presence of cobalt naphthenate, the product is hydrogenated and distilled to give crude 4. 5. 5-trimethylhexanol-1. The 4. 5. 5-trimethylhexanol-1 is reacted with phthalic anhydride in the presence of active alumina and di-4. 5. 5-trimethyl hexyl phthalate is separated from the resulting mixture.  Specifications 578,309, [Group XII], 667,109 are referred to.

The tail end is then passed through the loop 2 and threaded through the loops engaged by the staples 7, 8, being subsequently drawn tight whereby the slide 10 is drawn close up to the staples. The cord is then detached from the apparatus and the connection secured by further tightening and threading the needle 5 through the cord at other points, after which the excess portion of the tail is cut off. The method of using the apparatus in applying driving bands to single and double row spindles is indicated.

Title: Improvements in or relating to Telecommunications Systems
IPC: H04Q11/04
Filed: 1967-05-10
Abstract: 1,156,887. Automatic exchange systems. SIEMENS A.G. 10 May, 1967 [11 May, 1966], No. 21702/67. Heading H4K. In a 1000 line exchange having 990 teleprinter subscribers and 10 telephone subscribers, the latter are interconnectible over a speech highway, the control of such an interconnection being effected with the aid of a multiple line and a store which are also used for the transmission of data between teleprinter subscribers. The multiple line comprises many parallel channels, a unique selection of which is used in respect of each teleprinter connection. The line includes a magnetic core " store and forward" memory SP which comprises a storage cell for each subscriber in the system. The line is terminated by 1-out-of-N to binarycode converters ECW and ACW. In use, a pulse generator ZAK regularly transmits a pulse through the series chain of " call-up " circuits AS of which there is one per line circuit. The pulse is delayed in any line circuit that is in a " calling " condition. (" Calling ", here, means having a signal ready to transmit and not simply the usually understood on hook/off hook transition). The signal is transmitted together with an indication of the subscriber for whom the signal is intended over the " a " wire and input converter ECW to memory Sp, from where it is sent to the wanted subscriber via output converter ACW and wire " 6 ". As soon as the signal has been transmitted the pulse is passed on to the adjacent " call-up " circuit. The telephone subscribers' FgTn991- FgTn1000 call-up circuits are primed by pulses from a similar auxiliary pulse generator FAT (100Á sec. repetition rate) so that if such a subscriber is in a calling condition the occurrence of a pulse from ZAK after a primary pulse from FAT causes a signal to be sent over his " a wire to his cell in memory Sp. The cell already contains the address of the called party (the method of insertion is not disclosed) so that receipt of the original from the caller causes this address to be read-out and used to open the line gate S of the called party. The caller's line gate is pulsed simultaneously for use whereby an amplitude modulated speech sample can be passed over the two, or four wire highway ZAV. A 1Á sec. pause occurs to prevent the possibility of crosstalk on the highway whereafter the FAT call-up pulse is sent on to the adjacent call-up circuit. The call-up pulse from ZAK is passed on meanwhile and may be used for initiating a connection between a pair of teleprinter subscribers.

Title: Mine signalling device
IPC: G08B25/14
Filed: 1950-09-05
Abstract: 690,058. Electric selective signalling. METRA, NARODNI PODNIK, and BARVITIUS, F. Sept. 5, 1950 [Sept. 19, 1949], No. 21891/50. Class 40 (i). In a known mine signalling system each impulse received from the hauling level lights one lamp in a row 1a, 2a &c. while' each received from the driving level lights one lamp in a corresponding row 1b, 2b &c. both rows being situated in a panel with the tachograph A. The engineer operates the hoist on agreement of the number of lamps lit in each row. This system is modified to avoid the danger of the same lamp in each row corresponding to the last impulse of a signal failing, and thus giving a false indication, by arranging that each impulse lights one lamp and extinguishes the previous one so that on failure of a lamp no indication at all exists. At each signalling position each closure of a switch a operates through a relay' b and ratchet mechanism e a stepping switch g to light successively each of lamps 1 to 7 according to the number of impulses transmitted and at the same time sounds a single stroke bell z. This system may be applied to only one of the rows of lamps. Some disagreeing signals from the two sources are allowable and these are indicated by colouring corresponding bulbs in each row e.g. 4a, 5b and 5a, 4b.
