Abstract: 876,137. Yarn packages. CHEMSTRAND CORPORATION. June 23, 1959 [June 30, 1958], No. 21526/59; Class 94(1). [Also in Group XXV] A yarn package containing for example, nylon thread on a warp beam 11, is protected by a wrapper 17 wound into overlapping relation about the yarn, and held in place by elastic straps which gird the circumference of the package. The straps (see also Group XXV) may be of plaited nylon cord 18 having metal band extensions 22, 23 joined by a deformable seal. 24. The yarn ends are held in place by adhesive tape 16. The elasticity in the straps prevent wrapper looseness due to yarn shrinkage.

Title: Improvements in malting plants
IPC: C12C1/15

Abstract: 632,075. Malting grain. BODCHER, H. F. V. and HEIDENSTAM, E. J., VON. Aug. 23, 1945, No. 21633. Convention date, April 13, 1944. [Class 14(ii)] [Also in Group XXX] In a method of malting grain steeped grain is supplied in batches to an inlet zone in a perforated malting floor and moved intermittently a distance horizontally towards an outlet zone, while some of the grain in said outlet zone is discharged in batches whereupon the grain is moved back intermittently in the opposite direction a distance horizontally which is shorter than said first-mentioned horizontal distance. As shown a malting house 100 has perforated malting floors 101 below which compartments are formed extending at right angles to the direction from the inlet zone 1 to the outlet zone 8 of the floors and air is admitted to said compartments through ducts 102 through valves 99 below the floors and passes through the perforations upwards through the grain on the floors. The steeped grain is fed through an automatic revolving hopper 103 on to a movable flap 104 which distributes the grain over a longitudinal distance s and fills the space 1. After the grain has been left for e.g. 12 hours a conveyer 105 (see Group XXX) is started and moves along the floor from the right and the malt in space 8 which is finished malting is lifted and discharged through a hopper 108 on to a conveyer 110. As the conveyer moves to the left the successive batches of grain are turned over and moved to the right one place thus leaving the inlet zone vacant to receive a fresh batch of steeped grain after the conveyer has been moved up to the first batch (see Fig. 7, not shown). The grain is left to stand for about 12 hours and then the conveyer is tilted in the opposite direction and the direction of the buckets reversed and it moves to the right turning the batches and moving them one place to the left, when the conveyer reaches the left-hand end the grain is allowed to stand another 12 hours which completes the malting of the right-hand end batch which is discharged on tilting the conveyer and reversing its motor (Fig. 12, not shown) and the other batches are displaced to the left as before. Water may be sprayed in controlled amounts on the grain by means of a sprayer 98 anywhere along the traverse of the conveyer.

Abstract: 867,705. Photo-electric exposure control. KODAK Ltd. June 24, 1959 [June 30, 1958], No. 21728/59. Class 40(3) [Also in Group XX] In a photographic camera including a fixed area aperture through which light can be admitted to photographic sensitized material when positioned in the camera, a movable diaphragm vane having an elongated aperture of varying width, and at least one masking member for covering a portion of the fixed area aperture, said vane and masking member or members cooperate to form at different positions of the vane a composite aperture which is substantially centralized with respect to the fixed area aperture. As shown (Fig. 1), the moving coil 30 of a galvanometer is energized by a photo-cell 34 illuminated through lenticular lens system 36, and carries a pointer 38 co-operating with a diaphragm scale 40, visible in the viewfinder 42. Also carried by coil 30, so as to pivot in front of rear objective lens 12, is a vane 16 having a teardrop-shaped aperture 18 which together with a normally stationary masking member 24, determines the effective diaphragm aperture. In poor lighting conditions, mask 24 may be pivoted away from fixed aperture 12, by means of finger knob 28. In a modification, the masking member comprises two integral masking elements extending towards the centre from opposite sides of the fixed aperture 12. In a further modification (Fig. 14) the masking member is pivotally mounted at 88, comprises two elements 80, 82 and an arcuate portion 84, and is held in the position shown, abutting against fixed stop 100, by spring 90. The diaphragm vane 102 is pivotally mounted at 104, carries a counterbalance 106, has a curved V-shaped aperture 110, and has an ear 114 carried by an arm 112 which in poor lighting conditions abuts against arm 116 for automatically moving the masking member 86 away from aperture 12, against the loading of spring 90.

Title: Bistable electrical data storage circuit

IPC: H03K3/288
Filed: 1969-04-30
Abstract: 1,218,896. Transistor bi-stable circuits. INTERNATIONAL BUSINESS MACHINES CORP. 30 April, 1969 [2 May, 1968], No. 21912/69. Heading H3T. [Also in Division H1] A bi-stable circuit such as a cross-coupled pair of transistors T1, T2 has a read/write circuit, comprising for example transistors T3, T4 receiving an address pulse at their commoned bases, reaction being effected by feeding extra current to the bi-stable, and writing by extracting current from the bi-stable. Thus, if T2 is ON, an address pulse (positive) at A causes transistor T4 to conduct and feed current into T2, its collector B1 potential consequently falling and turning OFF a transistor T8 of an emitter-coupled pair T7, T8 to give a positive output pulse. When writing, one transistor, say T6, of a write input pair T5, T6 is turned ON by a positive pulse at its base, thus causing the potential at T4 collector B1, to which T6 collector is coupled, to fall. If T2 is OFF, the emitter of T4 will be positive and this transistor will operate in reverse when a positive address pulse occurs at A. The current thus extracted at the junction 15 of collector resistors R21, R22 causes the point 15 and T2 collector C2 to fall to a certain extent, turning T1 OFF. The reciprocal coupling completes the changeover, and T2 comes ON. An integrated circuit form of construction is disclosed (Figs. 2, 3, not shown).

Abstract: 149,349. Metropolitan-Vickers Electrical Co., (Assignees of Brackett, Q. A.). Aug. 5, 1919. [Conrention date]. Vacuum tubes.-A thermionic valve employed as a detector and amplifier utilizes the interference between two independent electron streams. A hot cathode 13 and an anode 14 are connected in the local circuit with a telephone 15, and a. second hot cathode 11 and anodes 9, 9 are connected respectively to the middle and ends of the aerial secondary 8. When oscillations are being received, a continuous rectified current passes between the electrodes 11, 9, 9 in the form of an electron stream which interferes with the stream passing from cathode 13 to anode 14, and so affects the current through the telephone 15. In modifications, the two electron streams may be parallel to one another and may move in either the same or opposite directions. A cascade of several tubes may be used.
