Patent GB-543611-A (GB)
Abstract: 543,611. Piezo-electric apparatus. BRUSH CRYSTAL CO., Ltd. Aug. 17, 1940, No. 13167. Convention date, Sept. 11, 1939. [Class 40 (v)] [Also in Group XIII] A piezo-electric apparatus comprises a vibratory mechanical system coupled to an artificially heated piezo-electric unit having substantially the properties of Rochelle salt. the unit being maintained at a temperature above the upper Curie point to provide constancy of actuation. Fig. 3 shows a pen recording device in which a multilaminar piezo-electric element 5, clamped at three of its comers in the manner described in Specification 534,758 has at its free corner an operating pin 9 which, through a multiplying arrangement B of the kind described in Specification 506,211, [Group XIX], and a damping means D of the kind described in U.S.A. Specification 2,241,837, operates a recording pen (not shown). Flat wound heating elements E, El are provided on each side of the casing 1 and serve, under the control of a thermostat F, to maintain the element 5 and damping unit at a temperature of between 30‹ C. and 45‹ C. which is above the upper Curie point for Rochelle salt and its isomorphs. In this temperature range, a recording instrument shows substantial linearity, constant sensitivity and comparative absence of " creep ". Also the impedance of the element 5 is high at this temperature, which enables it to be used with a high impedance oscillator and thus prevents risk of overloading the oscillator on starting up with the piezo element cold. Specification 318,934, [Class 40 (v)], and U.S:A. Specification 2,105,011 and Reissue 20,213 are referred to.

Apparatus for sealing cartons having a peripheral creased flap which can be folded to close the carton comprises a housing 1 in which are provided two pairs 3, 6 of oppositely arranged movable guides for bending flap portions towards their closed positions and a fixed guide member 4 for finally closing the carton by causing a tuckin extension of one of the flap portions to enter beneath and between the corner folds of the opposite flap portion. The open carton with upstanding flap portions is raised by a manually operated cam on a platform guided on vertical rods supporting the housing, the carton entering a rectangular opening 12 in the housing. The weighted guides or fingers 3 pivoted on two sides of the housing commence the inward folding of the two opposite non-interengaging flap members and thereby of the interengaging members, which are thereafter folded inwards as the carton rises by contact with the pair of weighted guides 6 pivoted at 6A to the guide member 4. The guides 6 comprise fingers 10 slidable in slots 11 in the side walls of the opening 12, and are held rigid by projections 8 on members pivoted to the housing. When the partly closed flap reaches the guide member 4, adjustable rods associated with the rising carton-carrying platform cause the projections 8 to release the guides 6, which allow the carton to rise and be pressed against the fixed guide member 4. The guide member 4 has a central ridge 5 which causes the tuck-in extension on the left hand flap portion to pass beneath the opposite flap portion. Specification 657,034 is referred to.
