Title: Improvements in devices for feeding folding boxes to packing machines
IPC: B31B120/30
Filed: 1930-04-29
Abstract: 351,156. Opening collapsed boxes. HESSER, MASCHINENFABRIKAKT.-GES. F., 99, Olgastrasse, Cannstatt, Stuttgart, Germany. April 29, 1930, No. 13129. Convention date, June 3, 1929. [Classes 18 and 94 (i).] A pile A of collapsed boxes, disposed . with their longer edges horizontal and with the end flaps projecting, is fed horizontally to the right on endless bands 10 towards an opening device 35 which opens them and transfers them into the pockets 70 of a packing machine. The endless bands pass round pulleys 7, 9 and are supported by idle pulleys 14. A weight 24, on a cord 21 passing over a pulley 22 to a feed plate 15 on a carriage 16, causes the pile to move so that the right-hand box is lightly pressed against rails 29, 30. The opening device, comprising a knifeshaped member 35, moves horizontally at rightangles to the direction of travel of the pile, and enters and partially opens the leading box. The member is then caused to move to the right and carry the box from between the rails 29, 30 into a pocket 70 of the packing machine, thereby opening it to a rectangular cross section. Pins 66 descend to the position shown in broken lines to prevent the box from collapsing or springing out of the pocket. At the next stage of travel of the chain on which the pockets are mounted, a creasing member 72 is swung against the upper wall of the box so as to cause the left hand upper edge to be sharply defined.

Title: Improvements relating to vocoder speech transmission systems
IPC: H04B1/66
Filed: 1965-03-29
Abstract: 1,032,718. Vocoders. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 29, 1965 [April 6, 1964], No. 13168/65. Heading H4R. In a vocoder in which a speech signal S 1 (t) is transmitted as information about the energy content of various bands A 1  to A n  of the speech frequency spectrum and information as to the fundamental frequency of the speech derived by an excitation generator AF, volume compression is applied to the signal after it has been split into the spectrum channels. The compression may be applied by deriving a control signal from the original speech in conventional manner in a unit R which is used, either to control the gain of amplifiers V 21 - V 2n,  or to control the settings of variable attenuators in the D.C. circuits GK 1  to GK n , in the spectrum channels. The control signal KR may be transmitted, e.g. along with the multiplexed spectrum and excitation function signals, to the receiver to control the gains of the individual spectrum channels at the receiver via a control unit RU, or alternatively, Fig. 6 (not shown), the control signal KR may be used at the transmitter to control the energy contents of the pulses of excitation function in a unit AFR, in such a way that when the modified pulses are applied to the modulators at the receiver the energy in the various spectrum channels is expanded in such a manner as to compensate the compression applied at the transmitter.

Title: Improvements relating to electric arc stud welding
IPC: B23K9/20
Filed: 1965-03-30
Abstract: 1,091,531. Welding by pressure. CROMPTON PAKKINSON Ltd. March 30, 1965 [April 10, 1964], No. 13466/65. Heading B3R. In an electric arc stud-welding tool 10 studs are fed into an inlet 80 and pushed into the jaws of a chuck 18 by a piston 130 ready for welding to a workpiece. The stud is pressed against the workpiece and causes a slight retraction of the tool parts 26, 28 against a spring 50, the said parts then being fully retracted by energizing a holding coil 52 to form the welding arc. A pilot arc is initially formed before the main welding arc is established. When the stud and workpiece have molten pools of metal the holding coil is de-energized and the spring 50 forces them together to complete the weld. The piston 130 may be manually or pneumatically operated against a spring acting to keep it retracted away from the chuck 18 and may be adjustable in its movement relative to the chuck. The studs are supplied to the inlet 80 by a feed mechanism. In one embodiment (Figs. 5 and 6, not shown) the feed mechanism comprises a hopper from which studs are fed and orientated to be blown through a flexible tube to the inlet 80, the tube having a feed passage having a shape conforming to the longitudinal cross-section of the studs which are fed through the passage sideways. In another embodiment (Figs. 7-10, not shown) the studs are loaded into a removable magazine attached to the tool from which they are blown into a feed passage and then pushed by a piston and further blown into the inlet 80. This latter stage of pushing and blowing the stud into the inlet 80 may be achieved mechanically by a device mounted on a foot 22 of the tool (Fig. 11, not shown) which comprises a plunger which is depressed when the tool is held against the workpiece and allows a stud to drop into a moving chamber which is subsequently aligned with the inlet 80 when the plunger is released and allows the stud to drop therein. Electropneumatic control is arranged with time delay devices to actuate the feeding and welding operations in correct sequence.

In a method of sealing the open end of a hollow body, e.g. an electric lamp envelope, with a glass membrane, there is formed a mass of molten glass having a surface layer of higher viscosity than an immediately underlying surface layer the viscosity of the surface layer being less than 100 poises, and the open end of the body, defined by a lip, is dipped into the surface layer and withdrawn with an adherent membrane of glass which then solidifies. It is preferred that the surface layer has a viscosity of 50 poises. The invention is particularly applicable to sealing envelopes made of potash or soda glasses, high melting point glasses or of an iron-chrome, or iron-nickel-cobalt alloy. The sealing glass may be a lead glass. It is also preferred that the glass of the lips and the sealing glass have substantially the same coefficient of expansion. In operation, the sealing glass may be melted electrically or by gas heating and the sealing may take place in an inert atmosphere. The length of the sealing operation is less than 5 sees., preferably less than 1 sec. Several embodiments of sealing operations are given. In one embodiment a photo-conductive element 26 (Fig. 4, not shown) is supported on a mount by a pair of easily bendable legs 27A of nickel wire connected to a pair of thicker support legs 27B of iron-nickel alloy, the assembly being mounted within a piece of glass tubing 25. The upper end of the tubing 25 is sealed about a glass bead on the legs 27B and the lower end then dipped into the surface layer of a pool of molten glass to seal that end with a membrane. To ensure a better seal the dipping process may be performed in a controlled atmosphere, the means for containing the molten sealing glass being on a water cooled base. Where the article to be sealed is an incandescent lamp, the filament lead-in wires may be sealed through the glass membrane. Some embodiments are given showing the application to sealing the annular gap or gaps between two or more concentric tubes, the dimensions of which are such that the end of the innermost tube remains unclosed.
