Title: Improvements in coin-freed apparatus
IPC: G07F17/16
Filed: 1919-05-09
Abstract: 149,408. Drybrough, T. B. May 9, 1919. Exhibiting moving pictures, figures, &c. - A screen is provided which, while allowing the exhibit to be visible, while at rest, to passers-by, is closed when the apparatus is set in motion so that the exhibit can only be seen through peep-holes. The screen comprises two curved shutters h supported by arms g from pivots f and having peepholes h<1>. These shutters are mounted n the upper exhibiting compartment of the apparatus, and are connected by links i, a lever j, and link k to a lever l pivoted at the base of a lower compartment and controlled by a balance weight m, the action of which causes the lever to move so as normally to move the shutters together to conceal the exhibit. The lever l is acted on by a clockwork-driven cam n so that when the period of display prepaid by the coin is over, the shutters are opened. The clock-work is controlled by a lever o engaging a flyer q on the shaft of the fan governor and extending into a coin-shoot p. A rod r pivoted to the lever o extends through a guide s and carries a detent t to which is attached a spring u tending to keep the parts in the position shown in Fig. 1. A snail r with a projecting pin w is mounted on the spindle of the cam n. On the insertion of a coin, the lever is raised from contact with the flyer q and held out of contact by engagement of the detent t with the guide s, and the motion of the cam n allows the shutters to close. On completion of the movement allowed by the prepayment, the pin w engages the detent and releases the lever to stop the motion, the cam n at the same time acting on the lever l to open the shutters. The snail v is adapted to engage the rod r to ensure the raising of the detent sufficiently to engage the guide, in the event of the action of the coin not being sufficient.

Title: Process for purifying polyolefins
IPC: C08F6/02
Filed: 1964-03-19
Abstract: Polyolefines, obtained by means of a polymerization catalyst consisting of the reaction product of titanium halide and an organo aluminium compound, are purified by suspending the crude polymer containing the catalyst residues in a liquid hydrocarbon and contacting it with oxygen, a free oxygen containing gas or an oxygen donor, in the presence of an aromatic hydrocarbon, ether, amine olefine or nitrogen containing heterocyclic compound, thereby transforming, at least in part, the catalyst residues into compounds which are soluble in the liquid hydrocarbon and which are removed from the polymer by washing with the hydrocarbon.  The polyolefine may be polypropylene.  The liquid hydrocarbon may be n-heptane which may contain 5-30% of one or more aromatic hydrocarbons, e.g. benzene, and may be technical heptane.  The contacting stage may be carried out at 20-100 DEG  C. using dry air and the polymer may be washed with n-heptane to remove any aluminium compound not bound to the titanium in the catalyst complex prior to the contacting stage.  The catalyst may consit of the reaction product of titanium trichloride and aluminium diethylmonochloride and the polyolefine may be produced by polymerizing the olefine in heptane.

Title: Cryogenic refrigerator
IPC: F25J1/00
Filed: 1966-03-17
Abstract: 1,129,781. Refrigerating. HUGHES AIRCRAFT CO. 17 March, 1966 [13 April, 1965], No. 11746/66. Heading F4H. The cold ends of the three cylinders of a Solvay engine contact thermally conducting discs 37 which abstract heat from coils 42, which, together with coils 41 around non-conducting discs 40, form a passage connecting a supply of compressed helium to a Joule-Thomson nozzle 15, cold gas from the nozzle cooling a parametric amplifier 46 through a conducting disc 107. Helium from the nozzle 15 passes in countercurrent flow over the heat exchange coils 41. The right hand disc 37 thermally communicates the cold end of the shortest cylinder with intermediate portions of the longer two, and the intermediate disc 37 thermally communicates the cold end of the intermediate length cylinder with a further intermediate portion of the longest cylinder so that the stream of helium passing to the nozzle 15 receives cold at progressively lower temperatures. The portions 42 of the helium passage contain carbon. The pistons of the Solvay engine are driven with 120 degrees phase differences by a swash plate assembly (24), Fig. 1a (not shown). Inlet and exhaust valves (31 and 32), Figs. 1a and 4 (not shown), for each cylinder are operated by cam tracks (28 and 29) on the swash plate assembly. The shortest and intermediate length cylinders have regenerators (as at 14 in Fig. 1b within their pistons through which gas is passed to and from the expansion spaces, and the longest cylinder has an external regenerator (19), Figs. 2 and 3 (not shown), which is in thermal contact with the three discs 37. In a modification, Fig. 6 (not shown), the three Solvay refrigeration stages are obtained by a stepped piston working in a stepped cylinder.

Title: A new or improved method of operating an adding and subtracting totalizer and mechanism for carrying out the method
IPC: G06C7/10
Filed: 1928-04-24
Abstract: 289,382. National Cash Register Co., (Assignees of Shipley, B. M.). April 25, 1927, [Convention date]. Adding and subtracting apparatus.-An add-or-subtract totalizer is provided with automatic means obviating the addition of the fugitive one when taking a negative balance, the totalizer wheels when disengaged from their actuators always standing at the true complementary values. As in Specification 8119/15 the totalizer may consist of positive and negative pinions 30, 31 geared together by reversing bevel wheels and mounted on a shaft 34 shifted by the rocking of a shaft 60 so as to engage one or other series of pinions with the actuators 41. Echeloned on the shaft 60 is a number of arms 61 each adapted when the shaft is rocked, to wipe past a lever 62 pin-and-slot connected to a yoke member 63 loose on a rod 63<1>. The yoke member has two arms 65, 66 each provided with a stud to bear on a cam 67, 68 secured respectively to the negative and positive totalizer pinions. To the yoke member is attached an arm 46 having a tooth to actuate a sleeve 45 carrying the bevel pinions 33 of the next higher order. Normally the totalizer pinions all stand at zero but when the totalizer is moved to engagement the arms 61 successively rock the yoke members against spring action and thus cause the sleeves 45 to move round to shift the pinions not in use back by one step, the pinions to be actuated meanwhile being held by the usual aligning plate 79. If nothing is entered in the totalizer the removal of the pinions from the actuators will result in the restoration of the shifted pinions, low parts of the cams 67, 68 permitting the yokes and therefore the sleeves 45 to return. If, however, a number is entered on any one of the pinions the cam attached thereto will prevent the return of its yoke member and consequently all the higher pinions will remain in their adjusted positions, so that the positive and negative pinions carry their true values. A bell is sounded whenever the totalizer changes sign, a hammer 96, Fig. 5, being then tripped by a lever 107 adapted to be rocked by one or other of two lugs 101, 102 carried by spur wheels geared with the positive and negative pinions of the highest denomination. The hammer is re-cocked by a hook 115 rigid with the indicator-aligning blade 112.
