Title: Plate type heat exchanger
IPC: F28F3/08
Filed: 1972-09-07
Abstract: 1371277 Plate heat exchangers KRA OSTBO 7 Sept 1972 [8 Sept 1971] 41509/72 Heading F4S Two fluids are in heat exchange with each other as they flow through generally axially extending flow paths formed in a pack of spaced-apart metal discs 8 by openings through the discs arranged in at least three radiallyspaced groups (e.g. 9, 10, 11), the innermost and an outer group (e.g. groups 9 and 11) communicating with inlet and outlet chambers (e.g. 22, 23) for one of said fluids and located at the ends of the pack, whilst at least one intermediate group (e.g. group 10) communicates, also at the ends of the pack, with annular chambers, e.g. 17, 18, to or from which the other fluid is conveyed via connections such as 6 or 7 extending through end walls 4, 5 of a cylindrical shell containing the assembly of plates. The shell may comprise as shown a cylindrical member 1, or it may comprise an outermost series of metal rings (71, Fig. 3) separating adjacent discs of the pack. In the form shown the separating elements between adjacent discs 8 are sealing rings 12, 13 of plastics material. The discs are secured together by a bolt 14. The openings, e.g. forming the groups 9, 10, 11, may be punched out of the discs 8 providing tongues 8A constituting extended heat-exchange surface. The openings in adjacent discs may be relatively staggered and may be rectangular, triangular or diamond shaped (Fig. 4). The plates may have annular corrugations, and may be formed with shoulders to retain in position the rings 12, 13. The heat exchanger may be utilized for heating or cooling milk, for heating air by steam or hot water; or for heating fuel or lubricating oil by hot water.

Title: Labelling apparatus
IPC: B65C3/14
Filed: 1972-09-07
Abstract: 1398886 Labelling machine H KRONSEDER 7 Sept 1972 [10 Sept 1971] 41560/72 Heading B8F A labelling machine can be readily adapted to apply labels supplied from a stack in a magazine for short production runs or to apply labels from a roll or strip for a long run. As shown a machine for applying shoulder and body labels to bottles has a stack 16 of shoulder labels and a roll 60 of body labels. The shoulder labels are removed from a stationary magazine by oscillating pallets 14 on a rotating transfer unit 10, the pallets being glued by a drum 17 and transferring the labels to a labelling cylinder 1 where they are held by grippers 6 against anvils 8. The labelling cylinder has resilient pads 4 which press the labels onto the shoulders of bottles 59. The body labels are drawn from the roll by rollers 34, 35 and severed by a rotary knife 36 co-operating with a blade 38. Rollers 40, 46 are rotated faster than the rollers 34, 35 and are spaced at less than a label's length from them so that prior to severing the leading end of the label strip is gripped between the rollers 40, 46 and the driven roller slips on the strip and holds it taut. After severing, the roll 40 accelerates the label to the peripheral speed of a labelling cylinder 2 which is similar to the cylinder 1 and coaxially beneath it. While on the labelling cylinder, the body labels are glued by a glue transfer drum 62 coaxial with the transfer unit 10 and supplied with glue by the gluing drum 17. In order to operate the apparatus with body labels in a magazine, the roll 60 is removed, and the glue transfer drum 62 is replaced by a transfer unit similar to the unit 10 but at the height of the labelling cylinder 2. In a modification (Figs. 6, 7, not shown), labels from a strip are supplied to glued surfaces of a rotary transfer cylinder and when a label stack is used it is inserted in an oscillating magazine and the labels are removed therefrom by the transfer cylinder. In a further modification, glued label transfer surfaces are carried on arms pivoted to the transfer cylinders and remove labels from stationary magazines or receive labels cut from a strip.

Breathing apparatus for anaesthesia or artificial respiration comprises a breathing-bag 6 connected to an inhalation pipe 5 and through a non-return valve 7 to a supply tube 3 which has a relief valve 8. The non-return valve and the relief valve are biased to closed position by a common spring 11, opening of the non- return valve increasing the bias on the relief valve. For closed circuit operation an exhalation pipe 2 is connected to the supply tube, a carbon dioxide filter 4 being provided. A bored valve piston 13 may be disposed at III between the exhalation pipe and the supply pipe. In one position the piston permits communication between the exhalation pipe and the supply tube for closed circuit operation and in another position the piston connects the exhalation pipe with atmosphere for open circuit operation. Artificial respiration or arresting of respiration is effected by applying appropriate pressures on the breathing-bag.

[Also in Division G3] In an arrangement for controlling the proportion of either or both of two liquids added to a particulate solid, the weight per unit volume of a sample of the mixture is detected and correction is made to the flow of liquid in predetermined increments at fixed time intervals according to whether the weight is above or below a pre-set range. As shown, either or both of two liquids is added at 24, 25 to pulverized solid material 10 fed at a constant volumetric rate to a pug-mill 12, the output of which is sampled at 17. The sample is fed at constant depth through a gate 19<SP>1</SP> to a constant speed conveyer 18 where its weight is detected, e.g. pneumatically, at 30. The weigher operates adjustable lower and upper limit switches 31, 32 which are periodically connected by a timing device 36 to electromagnets 37, 38 arranged to rotate stepping switches 41, 42, 43 one step in the appropriate direction each time they are energized. The periods correspond to the time taken for material to pass through the system. Switch 43 controls the flow of liquids by selecting pre-set resistors in the circuit of electro-pneumatic transducers 55, 56 controlling pumps 20, 21. Normally only one liquid is added at a time, the appropriate pump being energized by switch 42, but there may be an overlapping section where both are operated.
