Abstract: 992,541. Packaging machines; feeding hoppers. MOLINS ORGANISATION Ltd., and D. W. MOLINS. Feb. 7, 1962 [Feb. 8, 1961], No. 4697/61. Headings B8C and B8S. Cigarettes are delivered from cigarettemaking machines, shown in part at 1 and 2, on catcher bands 3, 4 and 5, 6 respectively to receptacles 7 and 8 in which they are supported in stacks 9, 10, Fig. 2, on a platform 11. The stacks are formed as the platform 11 is lowered through the receptacles 7, 8. When the platform is near its lowest position, needles 13 are projected into the end faces of the cigarettes to hold the stacks above a chosen level. A plate 14 is moved into the receptacle as support for the cigarettes held back by the needles. Those cigarettes below this level are lowered further on the platform 11 to a position where they are transferred by pusher plates 15a, 15b into a tray 17. The plate 15a first aligns the stack 9 with the stack 10, after which the two stacks are moved together. A wheeled carriage 20 carries the plates 15a, 15b through a cross-piece 19 and bars 18. Specification 877,875 is referred to.

Title: Improvements in press jaws
IPC: B29C65/00
Filed: 1947-02-18
Abstract: 632,204. Mechanical presses. ROBINSON, Ltd., E. S. & A., DAVIES, K. W., NICHOLAS, J., and BAKER, D. C. Feb. 18, 1947, No. 4732. [Class 87 (ii)] [Also in Groups VIII and XVII] A press jaw, particularly for use in heat sealing paper bags coated with thermoplastic material comprises a set of blades 14 which are movable relatively to each other to allow the pressing surface to accommodate itself to an irregular surface. The blades 14 are normally separated from similar blades 7 by means of a spring (19)-urged plate 17 which engages behind shoulders 15 on the blades 14. When in use, the blades 14 are forced back and they in turn force the blades 7 against a rubber or like block 8. This block is enclosed in a casing and thus tends to act as a fluid, ensuring that the pressure exerted by each blade is the same. Electric heating elements 21 may be provided outside a casing 12 enclosing the blades 14 or they may be incorporated with the blades. The use of two sets of blades helps to prevent loss of heat from the blades 14. The casings enclosing the blades may be formed from laminated steel plates and insulating sheets.

Filed: 1932-02-19
Abstract: 394,067. Emergency lighting systems. LITE WATCHMAN CORPORATION, 52, Vanderbilt Avenue, New York, U.S.A. Feb. 19, 1932, No. 5049. Convention date, Feb. 19, 1931. [Class 38 (iv).] In a lighting system for automobiles and other purposes wherein the lamps 10, 11 are each provided with upper and lower filaments 20, 21 for use in producing downwardly deflected and long range beams respectively, failure' of any one filament actuates an electromagnetic or thermostatic device to light the other filament in the same lamp and also the second filament in the other lamp, while failure of both filaments in one lamp automatically actuates an audible alarm. The distinctive contour and intensity of the modified light beam advises the driver of the particular lamp filament which has failed. The lower filaments 21 are connected to opposed windings 41, 43 of a relay 45, and the upper filaments to opposed windings 42, 44 of the same relay, a switch 55 determining the connection to the lead 26 to the battery 25 and generator 26. Failure of one filament causes the relay armature 57 to be attracted and to close contacts 65, 61, thus completing an auxiliary circuit through lead 63, the relay armature and frame, so as to light the other set of filaments in both lamps. Failure of both filaments in one lamp causes a rapid vibration of the armature, this giving an audible signal. In a modification, Fig. 3, the relay windings are replaced by windings 136, 137 around parallel bi-metallic thermostatic bars 130, 131, failure of the current in a winding due to the failure of a filament causing relative movement of the bars 130, 131 and the closure of contacts 140, 139 carried thereby, thus closing the circuit for the other set of filaments.
