Filed: 1951-08-14
Abstract: 699,046. Time switches. JUNGHANS AKT.- GES., GEB. Aug. 14, 1951, No. 19164/51. Class 38 (v) A time switch comprises a clockwork-driven drum 1 carrying on its periphery at, say, 15 minute intervals a series of tappets or riders 2 any one of which may be moved by hand from a central inactive position into one or other of two active positions wherein rotation of the drum causes it to engage a finger 3a or 4a and move a mercury switch 3 off or on at a time corresponding to the position of the rider on the drum. The mercury switch is held in one or other of its positions by a spring biased lever 6 engaging a wedge 3b. In the form shown in Figs. 1, 2, the riders 2 are threaded on a circular wire about which they can pivot into positions determined by a spring catch 9. In Figs. 6, 7, riders 15 are movable rectilinearly into their three positions, two of which are shown dotted, and the drum comprises two outer discs 10, 11, and an inner disc 12 with three grooves to receive and locate the ends 16 of the riders. A split ring 24 surrounds the circle of riders and may be rotated to enable any rider to be removed or replaced. The end 26 of any rider, according to its setting, is adapted to engage an arm, 17 or 18 of a lever 19 thereby rotating a shaft 20 which carries the mercury switch. This modification, in addition to having a drum which rotates once in 24 hours, has a minute dial rotating once an hour and co-operating with a fixed pointer to enable accurate time setting to be made. Any finger 26 of any rider may also be bent to enable operation of the switch to occur at times within the 15 minute intervals. To put the apparatus out of action on Sundays or holidays, the device may include Fig. 11, a cam 33 with a step which, once a day causes the sudden operation of a lever 34 and the movement by one step of a seven-pointed star wheel 39 which carries round with it a wheel 40 with seven holes 41 into any one of which a pin may be inserted. At the appropriate day this pin operates a wire 43 which rotates a shaft 46 carrying a wire 44 which moves the mercury switch 48 into the off position and also moves it axially so as to put it out of engagement by the riders on the drum.

Title: Process of preparing mixed ethylene polymers
IPC: C08F6/06
Filed: 1959-06-05
Abstract: Mixtures of ethylene polymers are made by polymerizing separate quantities of ethylene with two different catalyst systems, and mixing the resulting polymers to form a product with an intrinsic viscosity intermediate the intrinsic viscosities of the different constituent polymers.  By "intrinsic viscosity" is meant the number of decilitres of decahydronaphthalene in which one gram of polymer has to be dissolved at a temperature of 135 DEG C. in order to produce a solution having a viscosity twice as high as that of decahydronaphthalene at the same temperature.  The catalyst systems used are (1) those comprising titanium halides in which at least 20% of the titanium compounds are present as tetravalent titanium and (2) those comprising titanium halides in which at least 90% of the titanium compounds have a valency state of less than 4.  The titanium compounds of (1) and (2) are made by reducing a titanium tetrahalide with a metal hydride, or organometallic compound of a metal of Group I to III, of the Periodic System.  The process may be effected continuously.  The reducing agent may be sodium, calcium, aluminium, sodium hydride, cesium hydride, dimethyl magnesium, diethyl cadmium, dipropyl zinc, dihexyl zinc, methyl sodium, diphenyl cadmium, diethyl aluminium hydride, diisobutyl aluminium hydride, triethyl, tri-isobutyl, or trihexyl aluminium, diethyl aluminium chloride, diethyl aluminium bromide, di-isobutyl aluminium chloride, or dipropyl aluminium bromide.  The polymerization and preparation of the catalyst is generally effected in the presence of conventional organic solvents.  The ethylene need not be pure, it may include other gases and substances such as propylene, hydrogen, nitrogen, oxygen, saturated hydrocarbons, and/or moisture.

Patent GB-203790-A (GB)
Abstract: 203,790. Haddan, A. J. H., (National Cash Register Co.). June 14, 1922. Cash registers with voucher-issuing mechanism. -The cash drawer cannot be closed unless the voucher has first been removed from the issuing shelf and means controlled by the presence or absence of vouchers or pay-on-delivery bills upon the shelf prevents wrong depression of transaction keys. When a voucher remains on the shelf 7, Fig. 2, a feeling lever 10, previously rocked clockwise by lever 14 and printing platen 8 to allow the voucher to pass, cannot return to the normal position, and consequently through link 17 a rod 20 is rocked to bring a stop-arm 22 against the upper end of a lever 29 rocked clockwise by the release of the drawer. The lever cannot now be pushed back by the closing of the drawer and the drawer latch 23 cannot function to maintain the drawer shut. When the ticket is removed from the shelf the stop-arm 22 is raised to free the lever 29 and allow the drawer to be latched again. A voucher is issued for cash sales only under the control of a cash key 4, Fig. 5. For " pay on delivery " transactions the key 5 must be depressed, and this is only possible if a sales slip has been inserted for printing. If either a slip or a voucher lies on the shelf 7 the feeling lever 10 through links 67, 63 positions an arm 61 beneath a pin 62 on the cash key, thus preventing its depression. On the other hand, if a bill is not present on the shelf, a pin 70 is free to rise under the pull of a spring 70<a>, and this through link 78 swings an arm 73 to place a notch therein in the path of pin 76 on the key 5, which is thus locked against complete depression. The pin 70 is maintained normally in its lower position by the pin 76 against which bears an extension 75 of the arm 73. To permit insertion of the bill a finger lever 90 can be raised to swing the end of lever 10 out of the way.
