Title: Improvements in or relating to folding cartons and blanks for making the same
Inventor: FOYLE JOHN ROLAND
IPC: B65D5/22
Filed: 1950-06-24
Abstract: 719,292. Cartons. BOXFOLDIA, Ltd. June 14, 1951, [June 24, 1950.] No. 15814/50. Class 18. A collapsible carton having double side walls has an inner base attached to the two opposite inner side walls and supported above the outer base by making these inner walls shorter than their corresponding outer walls. The carton is formed from a one piece blank having outer side and end walls 11, 18 foldable up about an outer base 10, the side walls having inner walls 20 of less depth foldably attached to them. One of the inner walls 20 has the inner base 25 foldably secured to it, the inner base 25 being of less length than the outer base 10 to enable locking flaps 19 extending from the end walls 18 to fold over and tuck in between the edges of the inner base 25 and the end walls 18 and at the same time to enclose side tabs 13, 21 on the ends of the side walls thereby holding the carton erect. An adhesive flap 27 along the outer edge of the inner base 25 is adapted to be attached to the opposite inner side wall 20 such as to form a tubular structure which may remain flat for packing and transport purposes prior to erection of the carton. Additionally the inner base 25 may be of less width than the outer base to facilitate the folding flat of the tubular structure when the inner base is connected to the opposite inner side wall, one double side wall being made shorter than the other. Alternatively instead of the tabs 13, gussets may be provided between the outer side walls and end walls. The carton may be used to slide in a shell. Specification 656,015 is referred to.

Title: Improvements in door closing and checking devices
IPC: E05F3/04
Filed: 1931-06-02
Abstract: 373,424. Door closing and check devices. NEWMAN & SONS, Ltd., W. and NEWMAN, H. G., 268, Hospital Street, Birmingham. June 2, 1931, No. 16049. [Class 65 (i).] A spring-closing and fluid-check device for doors, particularly of telephone boxes, of the kind in which the check piston is operated by a crank pin or other means from a spindle attached to a spring-influenced angularlymovable arm connected to the door, is housed in a separate small compartment having an open front for the working of the arm, this open front being covered by the door when closed. The device is designed to occupy little space, so that it can be placed below the floor of a telephone box, the check cylinder being preferably secured to the back wall of the compartment and the operating arm preferably having a pin-and-slot connection with the door. In the arrangement shown, 1 is the wall of a telephone box, and 2 is the compartment enclosing the apparatus, situated below the floor of the box. The door carries a slotted bracket 23, in which engages a pin on the end of the operating arm 5. The arm is fixed to the spindle 17, which bears in a sleeve fixed in the check cylinder 6 and carries at its lower end a crank pin 15 engaging in a transverse slot in the check piston 7. The piston has a passage from one end of the cylinder to the other, through which the checking fluid flows under the control of a ball valve 13 in the usual manner. The door is closed by a spring 26, coiled outside the sleeve, which has one end attached to the cylinder and the other engaged in a hole 28 in the arm 5 ; several holes such as 28 are provided for adjustment of the tension of the spring. The crank pin is arranged to be approximately on dead-centre when the door is closed, so that there is very little check action during the final closing movement.

Abstract: 1,253,945. Determining mercury in a gas photo-electrically. INCENTIVE RESEARCH & DEVELOPMENT A.B. April 3, 1970 [April 10, 1969], No.16095/70. Heading G1A. In an apparatus for determining mercury in a gas, ultraviolet radiation from a mercury lamp 12 passes through a first chamber 1 including or forming a measuring cell containing the gas sample, and an auxiliary chamber 6 containing a reference gas, e.g. a mercury-free specimen of the sample gas, the difference between the outputs of the photo-cells 13, 14 being indicative of the concentration of mercury in the sample. The two chambers 1 and 6 are equal in length, and the end walls 4, 5, 9, 10 are transparent to U.V. radiation. In the embodiment shown the measuring cell is co-extensive with the first chamber 1, but a measuring cell may be formed by partitioning-off a central part of the first chamber with U.V. transparent windows 20, 21 Fig. 3 (not shown). In this case the two end portions of the first chamber also contain the reference gas. In both embodiments, the difference between the photo-cell outputs is displayed on a meter or recorder.

Abstract: 477,993. Rolling. BRASSERT & CO., Ltd., H. A., and FRASER, J. S. June 9, 1936, No. 16113. [Class 83 (iv)] Work from a roll pass c is returned to an upper pass e by guides f, h which are linked to adjustable spring yielding mechanism t so that, as a loop of work forms and enlarges, the guide h yieldingly pivots open about its shaft i, and when the trailing end of the work becomes free of the pass c the extra force of it trying to straighten itself in line with the rest of the bar going back through the top pass e, kicks the guide wide open against the yielding pressure whereby the links m attached to the guide at one end, pull the levers l about their shaft k, so forcing the heavy cross bar n, joining, their ends, out of the recesses p in the catch levers o, so swinging n upwards clear of o and so freeing the guide of all yielding pressure. When the trailing end has passed the guide h, the heavy cross-bar n falls back by gravity to re-engage in the notches p of the catches o and so resets the guides for the next workpiece. The guidef is coupled through lovers y and j to slide down as the guide h is opened, and is also reset along with the main guide.

Abstract: 259,537. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Geiger, P. H., and Grondahl, L. 0.). Oct. 7, 1925, [Convention date]. Converting pulsating currents into steady continuous currents.-Pulsating currents are converted into steady continuous currents by means of a resistance which varies in accordance with the applied voltage. In the arrangement shown, alternating current from the secondary winding 2 of a transformer, the primary 1 of which is connected to an alternating current supply, is rectified by an arrangement of solid unidirectional conducting devices 3, which may be of the kind described in Specification 257,305, [Class 37, Electricity, Measuring &c.]. The rectified current is supplied to a load L through reactances A, B, and a series of resistance elements 4 of the character in which resistance falls with increase in the voltage applied thereto are connected in shunt with the load, so as to cause a larger voltage drop in the reactance A with increasing current from the rectifier. The resistances 4 may comprise elements similar to those used as rectifying elements described in the prior Specification referred to; alternatively, galena or selenium, may be employed. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of material having a suitable temperature coefficient as the resistance. This subject-matter does not appear in the Specification as accepted.

[Class 37] An apparatus for comparing the physical state of paramagnetic materials with a standard specimen comprises means for subjecting the test and standard materials to an alternating flux and applying the voltages induced in associated windings to a differentially connected cathode ray oscillograph. In Fig. 1 the laminated core 10 is energized by coil 11 connected through commutator 14 to direct current source 12 and magnetic circuits are completed through test piece 24 and standard 25. Coils 17 and 18 are connected in series across resistance 23, and coils 15 and 16 are similarly associated with resistor 22. The magnetic fluxes produced in 24 and 25 induce voltages into coils 17, 18 and 15, 16 respectively which appear across resistances 23 and 22 and are applied in mutual opposition to the vertical plates of a cathode ray tube oscillograph 19, the horizontal plates of which are connected to a time base 20 which is triggered once per revolution by rotating contact-maker 21. coupled to commutator 14 or a thermionic oscillator may be used. In Fig. 2 (not shown) curves plotted as a function of time are drawn for the voltage applied to coil 11, the fluxes in the two specimens, the induced voltages and the pattern produced in the oscillograph screen, this last being a function of the differences between the two materials.
