Filed: 1951-10-26
Abstract: 694,699. Packaging machines. HESSER MASCHINENFABRIK-AKT.-GES, F. Oct. 26, 1951 [Oct. 30, 1950], No. 25126/51. Class 94(i) A machine for opening flatly-collapsed bags and for filling the same includes apparatus comprising an intermittently movable feed wheel against the outer face of which a bag, withdrawn by an oscillatable plate from a magazine of such bags in collapsed condition, is applied, and co-operating mechanical spreader and suction devices automatically operable at the bag-receiving station of the wheel to open the bag for subsequent filling. A flattened bag 2 in a magazine 1 is engaged, between its folded-up bottom and its side wall, by an oscillated plate 3 which carries the bag down against a flat wall 4a on a temporarily stationary intermittently rotated wheel 4. Here the bottom of the bag is engaged by a pivoted suction member 8 and the mouth of the bag by opposed suction members 5, 6 which, in conjunction with the wall 4a and an abutment 4b thereabove on the wheel, partially open the bag. A spreader device, comprising a hooked arm 7 pivotally carried by the wheel 4 and a hooked arm 7a slidably mounted in the arm 7 to move radially of the wheel, is then moved down into the mouth of the bag and the arms 7, 7a moved apart to complete the opening of the bag in conjunction with the suction member. Suction to the suction members is then cut off and the wheel 4 moved one step so that the bag now carried by the arms 7, 7a is positioned under a filling means 10, the bottom of the bag resting on a plate 9 which may be jigged up and down to consolidate the contents of the bag. The wheel is then moved another step to carry the filled bag above an endless conveyer, having pockets 11 and one of its guide wheels coaxial with the wheel 4. The spreader arms 7, 7a release the bag to drop it into a pocket 11 of the conveyer which carries it to closing means.

Title: Automatically regulated heating unit for central heating
IPC: G05D23/12
Filed: 1946-08-22
Abstract: 631,175. Radiators for heating buildings. VYMETAL, F. Aug. 22, 1946, No. 25131. Convention date, Aug. 22, 1945. [Class 64(ii)] [Also in Group XXIX] An automatically-regulated radiator 5 comprises an evacuated chamber partly filled with an auxiliary liquid 4 heated by an element into which steam under low or high pressure is passed, the outlet of condensed water being regulated by a thermostatically controlled valve actuated by changes in temperature in the room in which the radiator is situated. Steam is lead through a conduit 1 to a tube 3 connected to a regulating apparatus R, the condensed liquid returning through a valve 6 and a conduit 17 to the boiler. The valve 6 is connected through rods 7, 8, 9 to a plate 10 vertically slidable in the valve casing. Two membranes 11, 12 have one end fastened to the plate 10, the opposite ends being secured, respectively, to the lower and upper walls of the valve casing. Changes of pressure in a thermo-static tube 19, due to changes of temperature in the room, are communicated to the space 18 within the membrane 11 to actuate the plate 10. From above the plate 10 is acted on by atmospheric pressure and a manually adjustable spring 13, As the temperature in the room rises the plate 10 moves upwards to close the valve 6, reducing the flow of condensed water and hence the amount of heat communicated to the auxiliary liquid 4. The spring 13 may be adjusted by the' nut 14 according to an empirical scale on the valve casing, one end position of the nut corresponding to the minimum temperature necessary to prevent freeze-up and the other end position being set to prevent overheating. The auxiliary fluid may be. a hydrocarbon, such as benzol or carbon tetrachloride.

Title: Optical process for the exploration or reconstitution of pictures and device for carrying out said process
IPC: G02F1/07
Filed: 1929-08-19
Abstract: 317,791. Soc. Independante de Telegraphie sans Fil. Aug. 22, 1928, [Convention date]. Television.-In a scanning device the picture is illuminated by elliptically polarized light each picture - element being characterized by a particular orientation of the ellipse axes. At the transmitter the main lightbeam passes from the source 1 through a collimator 2, 3, totally-reflecting prism 6, polarizer 11, and divided cube 9 to the picture 10. The cube 9 is formed of two totally reflecting prisms, having different refractivities and joined base to base, so that light is both transmitted and reflected at this plane of contact. The light then passes through two scanning prisms 12, 13 so constructed that each elementary pencil composing the beam is rotated through an angle individual to it. The scanning-prism 12 comprises two wedges, fixed base to base, one being of laevo rotatory quartz and the other deutro-rotatory, the dimensions being such that the light at one edge of the picture is polarized perpendicularly to that at the other edge. The second scanning-prism 13 is similar but imposes a smaller degree of rotation and is turned through a right-angle with respect to the scanning- prism 12. A rotating analyser 14 extinguishes each picture element in succession. In order that the scanning-point may be sharply illuminated while the rest of the picture is uniformly illuminated, an auxiliary beam, passing through reflecting prisms 4, 5 and polarizers 7, 8, is employed. The polarizers 7, 8 are so set that the auxiliary beam is polarized at right-angles to the main beam and is of weaker intensity. Adjustment is checked by means of a photoelectric cell 16. A similar arrangement may be adopted at the receiving station, a paper or oiled fabric screen at 15 being illuminated directly or from behind while the source 1 fluctuates in accordance with the signals.

Title: Improvements relating to waveform shaping stages
Inventor: WELBY BRIAN GUY
IPC: G05B19/14
Filed: 1952-10-09
Abstract: 771,592. Statistical apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 1, 1953 [Oct. 9,1952], No. 25364/52. Class 106(1). [Also in Group XL (c)] Fig. 1 shows a reading device for a perforated paper tape 10 which is perforated with a central row of equispaced feed holes 11 and with symbol or character-indicating perforations 12 perforated, e.g. in accordance with a standard 5 unit code. The taps is frictionally driven by being gripped between parallel rollers 19, 20 the former being driven from electric motor 34 via differential gearbox 25 on either side of which are located brake drums 27, 30 which are operated on by brake shoes 31, 28 under the control of electromagnets 32, 29. respectively. The feed holes 11 ensure the arrest and accurate registration of the perforations in the tape with the reading light source 14 and the associated bank of photo-electric cells 15. When a feed hole 11 is in the position for correct alignment of the tape and reading head 13 the focused light from a source 36 is incident on a photo-cell 39 so that a control voltage, such as shown in Fig. 5(a), is applied from the location photo-cell amplifier 44 to the square wave generator 48 where it is converted into a square wave, Fig. 5(f) having its leading edge and trailing edges coincident with the times at which the input signal passes through two predetermined. voltage levels x, z, Fig. 5(a) (see Group XL (c)). This square wave voltage is applied via a cathode follower 52 to a gate circuit 65 (see Group XL (c)) which ensures that the signals 1 from the reading photo-cell bank 15 only pass to the reading apparatus whilst the square wave is present at the output of cathodefollower 52, i.e. whilst the tape 10 is correctly registered. The square wave output from stage 52 is also passed to a trigger circuit 56 having two stable states which is fed with negative pulses at terminal 57 whose leading edges mark the completion of the character-reading operation at reading head 13. Two anti-phase square wave outputs are obtained from the trigger circuit 56 such that when the tape 10 is being moved from one reading position to the next coil 29 is energized and coil 32 is de-energized so that shaft 26 is stationary and shaft 24 and roller 19 rotate rapidly to cause the tape 10 to travel along. When the next feed-hole 11 is reached the leading edge of the square wave from generator 48 is initiated which after differentiation triggers over stage 56 to energize coil 32 and de-energize coil 29 so that the travel of tape 10 is arrested. When the reading operation is completed trigger 56 is tripped again to cause the tape 10 to be drawn forward. The square wave generator circuit 48 (see Group XL (c)) prevents the tape from being wrongly positioned due to irregularities in the waveform of the control signal derived from the photo-cell 39.

Title: Process for dyeing cellulosic textile materials
Filed: 1957-08-13
Abstract: Cellulosic textile materials are dyed on the foulard or printed with a dyestuff containing at least one acid solubilizing group and at least one aliphatic halogenated acylamino group the acyl group of which is derived from an aliphatic carboxylic acid, and the dyestuff is then fixed by heating or steaming in the presence of an acidbinding agent, such as an alkali metal hydroxide, carbonate, phosphate, borate, perborate, alkaline-earth metal hydroxide, potassium cyanide and mixtures thereof.  The foularding liquor or printing paste may contain neutral inorganic salts such as alkali-metal chlorides or sulphates, and may contain the acid-binding agent from the outset.  Alternatively, the textile may be impregnated or printed with the dyestuff solution or paste and subsequently treated with a solution of the acid-binding agent prior to the first heating step.  As an alternative, a substance such as sodium bicarbonate which yields an acidbinding agent on heating may be incorporated in the dyestuff liquor or paste. Suitable dyestuffs are those of the stilbene, azine, dioxazine, acidphthalocyanine, anthraquinone and azo (including metal-free and metalliferous azo) series.  Dyestuffs containing metallizable groups may be metallized on the fibre.  Urea may also be added to the dyestuff liquor or paste.
