Rolling.-In accommodating the loop, which is formed when a sheet is rolled in rolls a and returned by guides and rollers d, e, f to smaller pass rolls b for further reduction, by the loop pushing down the pivoted bottom g of the guideway, means are provided for temporarily putting certain of the feed rollers out of action. When a loop tends to accumulate in the upper guideway h, it bears against a feeler i which operates electromagnetic, pneumatic, hydraulic &c. controls r, s, t to raise the feeding roll f so that the loop forms in the bottom g of the guide and tilts it. To avoid the formation of too great a loop both feed rollers f, d are disengaged from the roll e. In feeding long thin sheets which are not sufficiently rigid to push the bottom g down the bottom g is pushed down by an electromagnetic &c. control s. Instead of three feed rolls d, e, f two separate pairs may be used with a three high mill and the speed of the second pair may be less than that of the first pair.

Title: Films and sheets of thermoplastics material suitable for use as greenhouse coverings
IPC: A01G9/14
Filed: 1970-04-10
Abstract: 1312119 Cloches MONTECATINI EDISON SpA 10 April 1970 [10 April 1969] 17250/70 Heading A1E [Also in Divisions B5 and C3] An anti-fogging transparent or translucent film usable as a cloche is made from a thermoplastic material of a surfactant containing between 0.5 and 5.0 parts by weight per 100 parts of thermoplastic. The thermoplastic is preferably polyvinyl chloride. Tomatoes are grown in greenhouses constructed of this material and compared with others grown in greenhouses constructed of the polyvinyl chloride without the surfactant. The yields are claimed to be higher in the plants grown in greenhouses constructed from film containing the surfactant, and, further, the plants apparently crop earlier and grow faster. This is stated to be caused by the prevention of dew collection on the greenhouse, which dew can reduce the light and infrared passing to the inside.

Abstract: 1,038,600. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 26, 1965 [April 27, 1964], No. 17460/65. Heading G4A. In data storage apparatus including a record on which data is stored as a pattern formed of materials of different atomic weights, data is read out by directing a beam of electrons at the record and detecting the number of electrons scattered from the record. The electron beam is moved over the record in the form of a raster in synchronism with the movement of a second electron beam in a raster (which may be larger than the first) over the screen of a CRT display. The beam intensity in the CRT display is controlled by the number of electrons scattered from the record into a detector. Those electrons not scattered go to a meter. In Fig. 2 (not shown), the record comprises a photographic film covered with a very thin conducting layer connected to the meter. In Fig. 3 (not shown), the record comprises two layers of different materials, the upper layer having been selectively machined away, e.g. by an electron beam, to store data.

Patent GB-1343941-A (GB)
Title: Raster correction circuit
IPC: H03K4/83
Filed: 1971-05-28
Abstract: 1343941 Cathode-ray tube circuits RCA CORPORATION 28 May 1971 [5 June 1970] 17724/71 Heading H4T  In a television receiver, side = (EASTWEST) pin cushion distortion is corrected by varying the deflection current in the line deflection windings at field deflection rate during successive line retrace intervals. As shown in Fig. 1, a known type of horizontal output stage 40 supplies energy to the horizontal deflection yoke 46 and to the horizontal output transformer 60 during the second portion of each retrace interval so that at the commencement of the trace portion the current in yoke 46 is at a maximum and determined by the division of current between (1) the yoke 46, linearity circuit 48 and "S" capacitor 49 and (2) the primary 64 of transformer 60, capacitor 65 and the parallel connected pin cushion correction circuit 70. At the commencement of a field period t 0  (see Figs. 2A, 2B and 2C) the voltage V74 across a capacitor 74, forming part of circuit 70, is nearly zero whilst the voltage V65 across capacitor 65 is relatively high so that current flows from the latter into capacitor 74 via resistor 72 to tend to equalize their charges. This flow continues at a decreasing rate between t 0  and t 1  (the centre of the raster) and provides a parabolic loading of the output transformer which causes a changing amount of line frequency retrace current to flow into the primary winding 64. This results in a deflection current decreasing parabolically at field rate in yoke 46 which reduces the width of successive lines of the raster by a maximum amount at t 0  down to a minimum amount at t 1 . Shortly after the latter period, transistor 75, the base of which receives a voltage V75B (Fig. 2A) derived from vertical sawtooth V25 via R.C. circuit 78, 77, commences to conduct and the collector current I75C (Fig. 2B) discharges capacitor 74 by an increasing amount (V74 Fig. 2C) towards the end of the vertical scan and causes an increasing current to be drawn from capacitor 65 which thus loads the output transformer such that the width of successive lines of the raster is reduced by a minimum amount at t 1  up to a maximum amount at t 2 . The circuit of Fig. 1 includes a known type of voltage regulator circuit 50 and the inductor 38 which forms part of the horizontal output stage 40 includes a winding 38a providing a stepped-up voltage VB which can be employed to supply the operating potential for the video output stage. In a modification (Fig 3, not shown) the parabolic rate loading of transformer 60 is effected via an auxiliary winding which also provides, via rectifier circuits, the voltage + VA for the voltage regulator stage 50 and a low voltage power supply.
