Title: Improvements in or relating to cooling towers
IPC: F28C1/02
Filed: 1938-08-22
Abstract: 518,373. Cooling towers. BRANCZIK, K. W. Aug. 22, 1938, No. 24697. [Class 64 (i)] The lowermost part of the irrigation stack comprises a series of cooling laths 1 arranged in zig-zag fashion, so as to baffle the entering air and to cause the water to fall into the pond in sheets extending towards the centre of the tower. Part of the air passes between the sheets of water to the centre of the tower, the air passing between cooling laths 4a, 4b, in contact with cooling water which is delivered from troughs 12 on to spreaders 13 and arris boards 14 which distribute the water evenly on to the weather boards 4b below. One end of each cooling lath 1 may be notched as described in Specification 284,018, [Class 29], or formed with a spear head as described in Specification 289,313, [Class 29]. The angle between the weather boards and their supports may be varied in different parts of the stack, thus the weather boards 4a and 4b are disposed at 45 degrees and 60 degrees respectively to their supports 5. The spacing of the boards is greater in the centre to avoid resistance to the passage of air at the centre of the stack. The angle of the supports 5, Fig. 2, may be adjusted by hinging one end of each of them by a bolt 8 to a stack post 7, the other end being secured by a bolt 9 in one of a series of holes 11 in the opposite stack post. Specification 184,653, [Class 29], also is referred to.

Abstract: 422,772. Notebooks &c. SOLOMON, F. H., c/o Union Motor Garage, Ltd., Main Road, Muizenberg, Cape Province, South Africa. Aug. 28, 1934, No. 24755. [Class 16] In notebooks, diaries, memorandum pads, and the like of the type comprising a plurality of groups or blocks 1 of detachable strips or sections 2 so arranged that each strip, after being written upon or when finished with, can be torn off, while leaving undisturbed the strips unused or bearing current matter, the blocks 1 are so made and arranged that the end or edge 5 of each block is of undercut formation so as to enable the user to grip and detach only one strip 2 at a time. As shown, the pad of a notebook comprises a series of separate adjoining blocks 1 glued to a cardboard back 6, the strips 2 being glued together at one end 3, and partly glued along each side 4. A flap secured to the back 6 is adapted for insertion into a slot or opening in one side member of an outer cover. The cover has a pocket on the other side member for the reception of used strips 2. Instead of bevelling the end 5, each block may comprise a series of sets of four strips stepped at the ends, the strips in any set being differentiated by colour so that it can be seen whether the pad as a whole is being used uniformly or not. In a modification, instead of a pad comprising a series of blocks 1 entirely separated from each other, the pad comprises sheets secured together at one edge, each perforated adjacent and parallel to this edge, and divided by cuts extending from the opposite free edge to the line of perforations, thus forming a number of blocks which are joined together by a narrow round edge. The free ends of the blocks may be held together by an elastic band anchored to a flat member which is secured to the back of the pad. In addition to the pad of blocks the notebook may be provided with an ordinary ruled tearoff pad detachably secured in the notebook in the same manner as the pad, and for the purpose of receiving permanent notes.

Title: Improvements relating to liquid delivery apparatus
IPC: B67D7/58
Filed: 1932-09-06
Abstract: 407,348. Delivering measured quantities of liquids ; lubricating. CUTTS, R. M., Marine Barracks, Navy Yard, Philadelphia, U.S.A. Sept. 6, 1932, No. 24837. [Class 106 (v).] In apparatus for delivering measured quantities of liquid, particularly lubricants, at a number of points, of the type in which the measured quantity is separated by loose-fitting fluid operated plungers B forced upwards in cylinders A to deliver the liquid and returned through the liquid in the cylinder by gravity to separate off a further measured quantity, a check valve 113 preventing back flow of the liquid, means are provided for relieving pressure trapped by the check valve, so as to allow the plungers to fall. The liquid is contained in a tank 108 connected through a three-way valve 104 to a container 101 for air under pressure so that pressure may be put on the surface of the liquid to open the check valve 113 and force lubricant to the supply line 115 to raise balls B to the upper ends of the chambers A forcing the lubricant already contained in these chambers through pipes 120, 121 and non-return valves 125, 126 to the bearings. When all the balls are in their uppermost positions flow of lubricant ceases, and the check valve 113 returns to its seat ; and on turning the three-way valve 104 into the position shown, open to the atmosphere, pressure in the pipe 115 is relieved by a gravity non-return valve 123 in a pipe 124 by-passing the check valve 113. The ball of the valve 123 is of less weight than any of the balls B. The bye-pass 124 is made small so as to resist back flow through it, and when the pressure has been released the valve 123 closes again. The non- return valves 123, 125, 126 prevent gravity return, syphoning and loss of lubricant due to leaks. The compressed air supply may be replaced by a manual pump. The upper seating 114 of the check valve 113 is castellated to prevent sticking.

Abstract: 634,693. Lipstick holders. JARRETT, RAINSFORD & LAUGHTON, Ltd., and CURRY, F. J. Sept. 12, 1947, Nos. 25112 and 31520. [Class 18] A holder for a lipstick or the like comprises a cup 3 for supporting the lipstick, provided with a diametrically positioned pin 1 the ends of which extend through helical slots 5, 6 of an inner sleeve 7 into longitudinal grooves 8 formed in an outer sleeve 9. The grooves 8 are formed by providing ribs 21 in the sleeve 9, and the outer portions of the ribs serve as bearing surfaces for the cover 14. The base of the cup is pressed in to form two tongues 4 which together with the cup wall support the pin 1. The inner sleeve 7 is rolled up from a blank of material and is provided with a tongue 10 which engages in a slot 11 formed in a base 12 so that relative movement between the base and sleeve 7 is prevented. The outer sleeve 9 is adapted to slide over the sleeve 7, engaging with its grooves 8 the pin 1, and is provided with projections 17 which engage under an inturned lip 19 of the base 12 to prevent the sleeve 9 from moving axially. The top edge of the sleeve 9 is also inturned to retain the sleeve 7 in position. Spring tongues 13 provided on the base 12 engage the cover 14 and retain it in position. To actuate the holder, the cover is removed and the base 12 is rotated to move the sleeve 7 relative to the sleeve 9 so that the pin 1 is caused to ride up the slots 5, 6 and the grooves 8 to raise the cup 3 holding the lipstick.

Title: Improved device for positioning fish
IPC: A22C25/12
Filed: 1950-10-16
Abstract: 682,034. Fish heading. ARENCO AKTIEBOLAG. Oct. 16, 1950 [Oct. 22, 1949], No. 25205/50. ' Class 28 (ii). Fish A being conveyed broadside on, in the troughs 1 of an endless conveyer against fixed beheading knives 41, are accurately positioned lengthwise for beheading by pushers 20 on another endless conveyer 8 inclined to the first conveyer so as to give a pushing component to move the fish, head first, as well as accompanying the broadside-on movement of the fish towards the knives. A pusher 20 in the lower run yieldingly engages each fish surface with its lower edge and moves it lengthwise head first until its head contacts an arresting gauge plate 28 in each of a second conveyed series of headcontaining pockets 18. The pusher 20 then slips over the fish body until its lower edge engages the slightly projecting branchial arch whereby the fish head is then pushed hard against the gauge plate 28 until it yields by pivoting upwards against the resistance of a spring 29 whereby the head enters and becomes wedged in one of the conveyer pockets 18. In time the pushers 20 are pivoted up out of contact with the fish so that the head is held by spring pressure of the lower edge 46, Fig. 5, in the pocket 18 and is conveyed to the fixed beheading knives 41. The pushers 20 are pivoted up out of the troughs 1 at the end of their lower conveyer run by their pivoted arms 16 contacting a circular disc 21 on one end shaft of its conveyer and are allowed to return by the pressure of their springs by a like (other end) disc 22 at the beginning of their lower run. The cut off fish head is released from its pocket 18 at the end of its own conveyer run by another circular disc 35 on the conveyer shaft acting to pivot up the gauge plate 28. In alternative constructions the headarresting gauge plate 28 need not be pivoted and a non-travelling yielding gauge plate can be used instead. Such gauge plate can also be dispensed with. In such case a spit and/or a member for opening the throat of a fish may be used as in Specifications 568,214 and 642,897. The pockets 1 may be inclined to the conveyer 2 in which case the longitudinal push of the pushers 20 is suitably modified. Specification 682,059 contains subject-matter not claimed in this Specification.
