Title: Transparency mounts and method of making same
IPC: G03B21/64
Filed: 1949-09-30
Abstract: 666,366. Lantern slides. SEARY, E. G. Sept. 30, 1949 [Oct. 9, 1948], No. 25124/49] Class 98 (ii). [Also in Group XV] A transparency mount for use in e.g. a projection printer is formed from a paper blank C, having two apertures a, b which register when the blank is folded at D, and projections G defining the transparency seat portion F which are substantially obliterated by a pressure operation to which the folded blank is subjected after the transparency E is placed in position, in order to establish an adhesive bond between the two parts of the blank. The projections G are formed by embossing or indenting by a small punch having a bevelled end so that the projections are inclined at a small angle to the plane of section B. The adhesive used may be rubber or vinyl compound such as is employed in scotch tape, animal glue or preferably a temperaturesensitive adhesive such as polyvinyl acetate or nitrocellulose. The transparency is sealed in the mount and sections of the mount sealed together in either a single or two operations, by e.g. a flat iron hot enough to raise the adhesive temperature to about 300‹ F., or in the case of a single operation by an electrically-heated power press whose platen is formed with an opening having horizontal dimensions substantially the same as those of the transparency E. Alternatively the projections at the side of the aperture b opposite to the fold. may be omitted and the two sections bonded together only above, below and at the left-hand side of the aperture b by using a platen different from the one described above only in that there is no portion to the right of the opening and this is increased in size. The transparency may then be inserted between the two sections and the mount subjected to a second bonding operation in which the projections G are pressed back into the section B and the unbonded portions of the mount are bonded together.

Filed: 1951-10-29
Abstract: 707,098. Refrigerating. POLK, I. H. Oct. 29, 1951, No. 25271/51. Class 29 Articles to be frozen e.g. food packages are compressed between two spaced parallel refrigerated plates 15 the pressure being intermittently relieved and the articles moved in the plane of the plates during each relief of pressure so as to be re - compressed between other portions of the plates. The vertical freezing plates 15 are suspended from rollers 20 movable in slots 18 of vertically movable cross-bars 17 at each end of the plates and are supplied with refrigerant by pipes 22. The plates are moved horizontally to engage the packages by hydraulic pistons 35 and the cross-bars 17, are supported at their ends upon hydraulic pistons 23. An article-supporting platform 30 is movable vertically by a hydraulic piston 31. In use the space between the plates 15 is filled with packages and after freezing the pistons 35, 23 are actuated to move the plates apart and downwardly to shear the ice adhesions. The platform 30 may also be moved upwardly as the plates move downwardly. The plates are then returned to their uppermost position and the platform 30 lowered to expose a row of packages beneath the plates and an unfrozen row admitted at the top. The plates are then moved towards one another to commence the next freezing step, and the frozen packages transferred to a conveyer 37. To increase the pressure on the packages at each step the plates may converge downwardly. A refrigerated. plate may be arranged between the two horizontally movable plates and two platforms 30 used. The plates and the platform 30 may be resiliently mounted and the pistons 23 omitted. In a modification, Fig. 5, the plates 73 are carried by pivoted links 91 from vertical rods 85 slidable vertically in guides 90 and carried by a yoke 83 from a hydraulic piston 86. The plates 73 are also supported resiliently by rollers 76 on a fixed cross-member 74. By moving the yoke 63 downwardly the plates are simultaneously moved downwardly and away from each other to break the ice adhesions. Upward movement forces the plates on to the packages. The article support 30 may comprise a conveyer belt for carrying away the frozen packages. Fig. 9 shows a de-icer for the plates for use during periods when the machine is not full of packages. Rubber wipers 48 are attached to a frame 49 which supports the platform 30 and a deicing fluid is supplied to a sprinkler head 51 between the wipers.

Abstract: 758,831. Mixing fluids in flow. BOULY, H. G. (Thompson Products, Inc.). Sept. 15, 1953, No. 25469/53. Class 86. [Also in Group XXIX] Apparatus for combining separate fluid streams in equal or other fixed proportions comprises a substantially cubical block 11 having a number of independent inlet passages such as 24 and an additional pilot inlet passage 20 all communicating with a common outlet passage 28, the flow in each of the independent inlet passages being controlled by a valve 38 operated by pressure sensitive means such as the diaphragm 43, responsive to the pressure on the outlet side of the respective valve 38 and to the pressure of fluid in the pilot inlet passage at a point between a flow-metering valve 50 and the common outlet passage 28. The passages 20, 24 &c. open into the end face 12 of the block 11 to which is attached a header block 13 having corresponding inlet ports such as 15, 17. As shown, the block has three inlet passages such as 24 and a pilot passage 20. The three inlet passages open into valve bores 41 containing spaced valve guide rings or seats 39, 40 for the valves 38 which are similar and in the form of pistons with a central bore 79 and lateral grooves 42, the latter being adapted to provide communication between the inlet passages and shallow chambers 49 on the outer faces of the block. The chambers 49 communicate through externally-threaded orifice members 31 with the outlet passage 28. A similar orifice member is provided between the outlet 28 and a pilot chamber 51 communicating with the outlet side of the metering valve 50. The chambers 49 are closed by the diaphragms 43 which are clamped to the block 11 by dome-shaped plates 44 forming with the diaphragms 43 control pressure chambers 48 all communicating with the pilot chambers 51 through passages 80, 81. For equal flows, the four orifice members 31 have orifices of equal cross-section and for proportionate flows, the sizes of the orifices are varied accordingly. The pilot valve 50 is located in a threaded bore 55 between the passage 20 and the pilot chamber 51 and comprises a spring- loaded valve 57 having a central passage with a calibrated restriction 61 to accommodate small flows. For larger flows, a shoulder 67 on the valve moves away from a shoulder 68 on a valve guide member 63 exposing ports 65 which permit a larger flow to by-pass the restriction 61. The maximum flow is however governed by the size of the orifice connecting the pilot chamber 51 to the outlet passage 28. Specifications 758,908 and 758,909 (both Group XXIX] are referred to.
