IPC: B65D81/38
Filed: 1920-04-28
Abstract: 166,737. Drinkwater, C. M. April 28, 1920. Luncheon cases.-A case for holding meals for hospital patients &c. comprises upper and lower sections 2, 1 which are detachably lunged together and are formed with partitions to separate the different foods, the meeting faces of the sections 1. 2 being formed with tongue-and-groove joints 8, 9. Each of the sections 1, 2 comprises inner and outer metal walls with a vacuum or insulating-material between them. The lower section 1 contains a removable subdivided tray 14 having a recess 47 for holding butter, and outside the tray are other compartments 40, 41, 42 and pockets 44, 46 for holding a cup and coffee-pots. When the upper section 1 has been raised, it can be disconnected from the lower section by moving it laterally, thus withdrawing the hinge-pins from their sockets.

Title: Patterned films on substrates
IPC: H01L21/3205
Filed: 1976-03-24
Abstract: 1482898 Patterned films on substrates INTERNATIONAL BUSINESS MACHINES CORP 24 March 1976 [9 May 1975] 11810/76 Heading H1K A method of making a patterned film (18), Fig. 1H (not shown), e.g. of metal or an insulating material, on a substrate 11, comprises the steps of forming a layer 12 of polydimethylsiloxane resin having a preponderance of Si-O bonds relative to the number of Si-CH 3  bonds on an organic polymeric material layer 10, forming on the layer 12 a masking layer 13 typically of a photo or electron beam resist material, and having openings 14, sputter etching in a first gas ambient to form openings 15 in the exposed portions of the layer 12 followed by another sputter etching in a different gas ambient to form openings (16), Fig. 1F (not shown), in the layer 10, depositing a film on the substrate through the openings 15, 16 and then finally removing the layers 10, 12 to form the patterned film 18. The layer 10, preferably of a photo-resist material, is baked prior to the deposition of the transparent resin layer 12 which is spun-on the layer 10. The resin layer is sputter etched in a gas containing fluorine, and prior to the second sputter etching of the exposed layer 10 in oxygen, the layer 13 is removed using a solvent. After the depositionof the metal or the insulating film, the layer 10 is dissolved in, e.g. acetone or iso-propanol.

Title: Resistance-capacitance electric oscillators
IPC: H03B5/22
Filed: 1944-06-21
Abstract: 587,680. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 21, 1944, N�. 11819. Convention date, June 21, 1943. [Class 40 (v)] In an oscillator comprising two valve stages in which the second stage is back-coupled to the first by a frequency determining resistancecapacity network, zero phase-shift coupling from the first stage to the second is achieved through a common cathode resistance. In one embodiment, Fig. 2, the feed-back circuit from valve 2 to valve 1 comprises a Wien-bridge network 10, 11, 9a, 12 and the output of valve 2 is maintained in phase with that of valve 1 through the common cathode resistor 16. The output may be amplified and rectified to provide a controlling voltage for the amplitude of the oscillations, Fig. 4 (not shown). In another modification, Fig. 5, the first stage comprises two serially related valves 31, 32, and the second stage a valve 42 whose cathode would be maintained at zero potential by the potentiometer 45, 46 across the H.T. supply but for the shunting action of the valves 31, 32. Increase in potential on the grid of valve 31 increases the anode current of the valve, thereby increasing the negative bias on valve 32 derived from resistor 38. Valve 32 thereby increases its impedance so that more of the anode current of valve 31 is drawn through resistor 41 so increasing the negative bias on valve 42, so that its output potential to the resistance-capacity feed-back network becomes more positive, i.e. zero phase shift is achieved. In a further modification, Fig. 5 (not shown), a further valve having a resistance and inductance in its cathode lead shunts the output of the second stage in order to correct for errors in phasing due to stray capacities and the like.

Title: Process of producing butter and cheese from animal milk
IPC: A23C15/06
Filed: 1935-04-23
Abstract: Cheese is made from skimmed milk or butter and cheese are made from whole milk or cream by adding a quantity of citric acid just sufficient to curdle the casein therein, butter being next made and separated off where whole milk or cream are used, the buttermilk or the curdled skimmed milk being finally heated to agglomerate the casein and produce cheese curds.  In an example, citric acid is added to whole milk to the extent of about 5 gm. per 1000 c.c. of the milk which is at room temperature, after standing about 15 minutes the coagulated milk is churned and the butter removed and washed and salted.  The buttermilk is heated to about 42 DEG  C. and the curds separated by straining in a warm room containing fairly moist air. Where an increased fat content is desired in the cheese, whole milk or cream is added to the buttermilk.  The milk used may first be pasteurized or boiled and may be cow's or goat's milk.

Abstract: 595,450. Shearing. STEVENS, A. H. (Fabriksaktiebolaget Haldataxametern). June 26, 1944, No. 12128. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 27, 1945.] [Class 83 (iv)] Shear-blades.-In a tool-holder for a plate shearing machine having a fixed and a reciprocating tool, one of the tools is adjustable laterally by means of a rotatable sleeve mounted on the holder and having an inner eccentric guide surface which bears on one side of the tool. The lower arm 7 of the machine has a vertical bore within which is a rotatable holder 6 having in its upper end a radial recess 8 within which is mounted the stationary tool 2. Mounted within the upper part of the bore and surrounding the upper part of the holder 6 is a rotatable sleeve 11 whose axis is coincident with the axes 12 of the holder 6 and of the upper reciprocating tool 1. The inner surface of the sleeve is however eccentric and bears against the outer side of the tool 2 which may thus be adjusted laterally relatively to the tool 1 by releasing a wedge 13, rotating the sleeve 11 and again tightening the wedge through a screw 14. A screw 15 allows the tool 2 to be adjusted longitudinally. After releasing a screw 20, the holder, sleeve and tool may be rotated as a whole and set at different angles a corresponding rotation of the upper tool 1 also being necessary.

Headings B3E, B3Q and B3W. Apparatus for stamping, bending or punching holes in sheet metal comprises a chamber containing a liquid into which a plunger is driven for generating a work-forming pressure wave and a passage of decreasing cross-sectional area leading to a nozzle through which issues a jet of the liquid. A blow may be struck on the plunger 3, Fig. 1 by an air-punch for forcing a jet (9) of water against the workpiece (11) to form it into a die (10). Several strokes of the plunger may be required, and the jet-pressure on the work-margin may serve as a hold-down. The die may be in sections and perforated (12), Fig. 3 (not shown), where holes are required in the workpiece. If irregular holes are required (15), Fig. 5 (not shown), the workpiece (11) is held against the die (10) by a clamp (16). The jet (9), Fig. 4 (not shown), may neck a tubular workpiece (11) about dies (13, 14). The workpiece is preferably heated; hardness and workability may be influenced by using quenching oil as the jet liquid. The pressure wave, passing along the convergent passage (20), Fig. 8, may form the workpiece (22) by fluidinflation. In another construction, Fig. 11 and Fig. 12 (not shown), the passages in the chamber 1 and in the die 21 contain steel transmission mediums 31, Fig. 11, and (35) Fig. 12 to accelerate a part of the pressure wave 1 which is thus first to strike the workpiece (29), the remainder of the shock wave completing the forming operation. A plurality of jet nozzles may be provided, Fig. 10 (not shown).
