Title: Improvements in or relating to superheterodyne radio receivers
IPC: H04B1/26
Filed: 1931-09-17
Abstract: 389,505. Valve amplifying circuits. KOLSTER-BRANDES, Ltd. and PERCIVAL, W. S., Cray Works, Sidcup, Kent. Sept. 17, 1931, No. 26049. [Class 40 (v).] In a superheterodyne receiver designed to operate on two or more wave-bands the normal sequence of a high-frequency stage V1 followed by the first detector V2, used on the longer-wave setting, is converted by a switch S1 .. S5 into an autodyne detector V1 followed by the first valve V2 of the intermediate-frequency stage. The switch contacts S1 .. S5 are open on the long-wave or normal setting. For short-wave reception, where a high-frequency stage might prove unstable, the coils L2, L3 are switched into circuit, the former short-circuiting the long-wave coil L1, and the latter providing a back-coupling which converts the valve V1 into a combined oscillator and detector. The condenser C1 acts to shorten the aerial, whilst the reaction condenser C also serves to tune the coil L4 of the valve V2, the secondary coil L5 being aperiodic. The contact S5 cuts out the separate oscillator O on the short-wave setting.

Title: Air preheater and dust collector
IPC: F23J15/02
Filed: 1928-09-12
Abstract: 297,423. Drake, W. C., Priebe, E. B., and Buchert, H., (Assignees of Coutant, J. G.). Sept. 21, 1927, [Convention date]. Feedwater, heating.-A furnace air heater applicable also for heating water consists of a number of tubular elements through which the gas passes and is subjected to centrifugal action, thereby causing the dust to pass out through lateral apertures. One form of tubular element is shown in Figs. 5, 5<a>, and consists of a metal tube a split longitudinally to form an opening a<1>; the tube contains a steel strip a<2> twisted into a helical form to cause the gases to rotate. In another form the split tube contains a wire helix upon its inner surface. In another. form two tubes a, a<5>, Fig. 7, are used; the inner tube a contain the helix and causes the separation of the dust while the liquid or gas to be heated passes through the space between the tubes. The tubular elements are built into units of the sector type, as shown in Fig. 9, or the rectangle type as shown in Fig. 10. A plate b is arranged near the lower end of each unit casing d to catch the separated dust and lead it to the discharge opening from whence it is taken by a worm or other conveyer back to the combustion chamber. A number of rectangle-units are shown combined in Fig. 1 to form a pre-heater and separator, the apparatus being provided with connected valves f<2>, g<2> to control the flow of gases. A motor j<2> operates the valves so that the units are open in pairs. With the parts in the position shown, the. hot combustion gases enter the lower rear opening i<2>, pass through a valve and upwards through the unit e<3>, where they yield their heat and dust, then emerge through the upper open valve and pass out through the conduit h<2>. The cold air to be heated enters through conduit h<1>, passes through an open upper valve, through the unit e<1>, where it is heated and escapes through opening i<1>. After a certain time the valves are operated to change the units in use. In the form shown in Fig. 2, the units are built into a cylindrical form. The cold air to be heated enters through the pipe n<2> and passes through a rotary slide n to the tubular heaters. It leaves the heater by the lower rotary slide o and pipe o<2>. The hot gases enter by the pipe m<3>, pass through the tubular members not covered by the slides n, o, and leave the apparatus by the pipe m<4>. The separated dust is collected by conical collector sheet b<2> and may be withdrawn through the hollow shaft p and the pipe p<1>. In another form the pipes and slides n, o are stationary, while the tubular structure is rotatable.

Title: Improvements in labelling apparatus
Inventor: KAY JAMES ARTHUR
IPC: B65C9/16
Filed: 1958-08-15
Abstract: 853,151. Labelling machines. ROSE BROS. (GAINSBOROUGH) Ltd. Aug. 14, 1959 [Aug. 15, 1958], No. 26256/58. Class 73. Relates to a labelling machine for applying labels to rectangular packages, the labels extending over one side and the two end faces of the package. Packages 26, Fig. 1 are fed from a feed channel 27 to the successive pockets 11 of an intermittently rotating pocket wheel 10 by a reciprocating pusher 28 and are ejected by a similar pusher 31 at a diametrically opposite station. A middle gum bar wheel 16 formed with middle gum bars 17 is driven synchronously with the pocket wheel 10 by a pair of chains 23 engaging sprockets 13 and 19, Fig. 2 secured to the shafts of the wheels 10 and 16. The chains 23 carry end gum bars 24 at spaced intervals corresponding to the circumferential pitch of the middle gum bars 17 and the pockets 11. The pairs of end gum bars 24 are spaced laterally by a distance slightly greater than the length of the middle gum bars 17 so that the latter pass into the spaces between the bars 24 to form, in effect, a single gum bar corresponding in length with labels 59 contained in a magazine 44, the end gum bars 24 moving into register with the middle gum bars 17 or the pockets 11 at each intermittent movement of the apparatus. The bars 17, 24 lie in the same plane as they pass in contact with a gumming roller 51 and also as they rest in position opposite a reciprocating label magazine 44 where they extract a label 59. As the wheel 16 rotates, the gum bar 17 moves out of the plane of the gum bars 24, thus leaving the gummed label 59 bridging the gap between the end bars 24 which subsequently dwell in register with a pocket 11 at the delivery station. A package 26 is ejected and passes between the gum bars 24 to engage the label 59 and carry it into a folding channel 61 consisting of a pair of spaced brushes 62, Fig. 3 (not shown), serving to fold over the end portions of the label 59 on to the end faces of the package.
