Title: Improvements in or relating to methods and apparatus for manufacturing Corrugated Board
IPC: B31F1/28
Filed: 1967-06-15
Abstract: 1,194,708. Laminated corrugated boards. PALSON CORP. A.B. 15 June, 1967 [20 June, 1966], No. 27757/67. Heading B5N. Corrugated board is manufactured by corrugating a paper web 8, this web, or smooth paper webs 11 and 12, or all, being coated with fusbile material, and applying to the coated web or webs, e.g. by nozzles 9, streams of hot air to melt the coating or coatings as the webs are brought into contact with one another so as to unite the crests of the corrugated web with the smooth web or webs. The corrugations may be produced by toothed cylinders 7 which may be heated to facilitate bending of the coating which is preferably of a mixture of thermoplastics and waxes having a melting point of about 65 to 85 C. The webs are united under the action of rolls 10 but, if desired, further rolls in an electric oven may be used to reduce the thickness of the laminate to a predetermined value.

Title: Improvements relating to heat exchangers
Inventor: SIXSMITH HERBERT
IPC: F25J5/00
Filed: 1957-09-05
Abstract: 842,577. Liquefaction of gases. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 27, 1958 [Sept. 5, 1957], No. 28070/57. Class 8(2). In a heat exchanger of the regenerative type serving to cool compressed gas prior to adiabatic expansion in a turbine 5 to effect liquefaction and comprising three chambers All, A12 and A13 controlled sequentially by a continuous or intermittently rotated valve 51 of the warm end and by pressure controlled valves V27, V28 and V29 at the cold end, the valves being so operated that during each stage one chamber e.g. A11 is warmed and so cools incoming gas, the second chamber A12 is cooled by a smaller quantity of returning low pressure gas flowing in the reverse direction, whilst the third chamber A13 is cooled by recirculation of a portion of the compressed gas from the cold end of chamber A11 so as to maintain a total heat balance in the chambers, means is provided whereby said portion of cold compressed gas is passed temporarily from the warm end to the cold end of the third chamber A13 through the valve 51 so as to build-up pressure sufficient to open the appropriate valve V29 and allow said portion of cold compressed gas to pass from manifold 4 through the chamber A13 from the cold to the warm end thereof. Said means comprises a venturi R1, a duct 10, heat exchanger 70, a flow control valve 72 in parallel with a non-return valve 71 which when valve V29 has opened allows said portion of cold compressed gas having traversed chamber A13 to rejoin the main stream entering the turbine 5. The latter discharges through a duct 6 into a condenser 7 which also receives expanded gas from a valve 9 and liquefied gas is drawn off by an automatic expansion valve 12 which discharges to an automatic float trap 13. The low pressure vapour from condenser 7 traverses the chamber being cooled e.g. A12, a duct 54 and an axial outlet of the valve 51. The compressed air inlet duct 60 of the valve 51 is constantly connected to a recess 61 of the rotary plug 56 and a second recess 63 is always connected to the duct 64. Specification 727,904 is referred to.

Title: Improvements in rotating bottling and like container-treating machines
IPC: B67C3/24
Filed: 1945-10-25
Abstract: 604,776. Bottling machines. AKTIESELSKABET ALTHOUN & NIELSEN, O. KIELLERUPS EFTF AF 1929. Oct. 25, 1945, No. 28192. Convention date, Oct, 25, 1944. [Class 125(ii)] In a rotary bottling machine, bottle tables 7 are lifted to present the containers to a filling nozzle by engagement of a roller 11 connected to the table with a preferably helical cam track 13 on a drum 12 rotating about a vertical axis. A table 7 is held in the raised position by means of a pawl 10. As a bottle 6 rises, it lifts bell 5, and filling tube 4 enters the bottle neck until the latter is pressed against filling nozzle 3 by the pressure of spring 9. As a safety arrangement, undue resistance to the lifting of table 7, due to misalignment of a bottle or other reasons, causes downward axial displacement of drum 12 on its driving shaft 15 against spring pressure, thereby actuating a stop motion. Since the pressure of spring 9 during compression at the end of the lifting movement would be sufficient to shift drum 12 and stop the machine, the drum is given axial support by a circular flange at the bottom thereof which rests on a fixed roller (not shown). The circular flange is set back from the fixed roller near to the bottom of cam track 13, so that the drum may yield axially and the safety arrangement may function at this point. Drum 12 is driven from the main belt pulley 16 of the machine and may rotate continuously or intermittently. After the bottle 6 has been filled, pawl 10 is pulled out of engagement after which roller 11 rolls down a stationary cam track.
