Abstract: 1,092,073. Diapers. RIEGEL TEXTILE CORPORATION. June 18, 1965 [April 1, 1965], No. 25986/65. Heading A3V. [Also in Division D1 In a process for forming folded diapers automatically, a textile web 11 is folded by arms 14, 15 and tapered means 17 to form a central thicker zone (21) (Fig. 6, not shown). The folded web passes round a roller 24 to sewing machines 27, 28 where the folds are stitched and then through feed rollers 36, 37, 40-43 driven by a motor (not shown), which draw the web from the supply roll 10 and through the folding means and pass it to a pneumatically operated guillotine 50. To ensure a clean cut stop means (75), Fig. 8, are associated with the guillotine to interrupt the rotation of feeding rolls 42, 43 when the blade 51 is lowered to make a cut. The individual diapers 95 are received by conveyers 96, 97 and plates 100, 101 which pivot to deposit the diapers singly on a conveyer 117. Further conveyers carry each diaper to a machine 129 which oversews one cut edge and then deposit it on a conveyer 130 for travel back to a machine 135 which oversews the other cut edge. Mechanism for stacking the finished diapers comprises pivotable plates 140 which deposit the diapers on a conveyer 145, each diaper before it falls contacting a switch 150 which when a predetermined number of diapers have contacted it, causes the conveyer 145 to move forwards to receive a fresh stack.

Filed: 1959-07-31
Abstract: 923,502. Engine turning gear. H. PAPST. July 31, 1959, No. 26339/59. Classes 7(3) and 7(5) The invention relates to a starter drive for an engine provided with a motor starter and generator unit and comprising an intermediate shaft and means for supplying the engine with fuel operably connected to the intermediate shaft. When the engine is to be started the electrical machine 2, connected as a motor, is energized and by way of the gearwheel 4, the gear teeth 7b carried by the member 7, the intermediate gears 11 and 12 and the teeth 6a of the member 6 sets the coupling member 6 in rotation. The nut 8 in consequence of its engagement with the thread 1c is forced to the left and presses the member 6 against the coupling member 10 so that a friction coupling is obtained and the crank shaft is set in rotation. During idling the coupling nut retains the position illustrated but is not able to exert great axial pressure on the member 6. On acceleration the thread 1c causes the coupling nut to be moved to the right. The rotation of the crankshaft is then transmitted through the member 7 and the gearwheel 4 to the electrical machine 2 which has meanwhile been connected for operation as a generator. A disc 18 is disposed on the shaft 3 and is associated with a fuel supply line 19, 20. On rotation of the disc the fuel is withdrawn in the form of a thin film and introduced into the carburetter chamber 29. On starting the speed of the disc is higher than if it were connected to the crankshaft. A fuel pump 16 and an oil pump 17 are connected to the shaft 13.

Title: Improvements in or relating to the production of emulsions of polymerised esters of acrylic and methacrylic acids
IPC: C08F20/12
Filed: 1945-10-12
Abstract: Emulsions containing polymerized esters of acrylic and/or methacrylic acids are produced by a process characterised by forming an emulsion of the monomeric ester or mixture of esters in an aqueous medium in the presence of a water-insoluble organic compound having a hydrophilic group and a water-soluble ionisable emulsifying agent. The process may be effected by forming a mixture of the ester, or mixture of esters, with the water-insoluble compound and emulsifying the mixture in an aqueous medium containing the water-soluble emulsifying agent.  A plasticizer may be added before emulsification or the plasticizer, emulsified separately, may be added before, during, or after polymerisation.  Preferably the water-insoluble compound is mixed with the hot plasticizer and the monomeric material added later. An emulsion stabiliser, e.g. partially or completely hydrolysed polyvinyl acetate may be included in the emulsion. Suitable water-insoluble compounds containing hydrophilic groups are long chain alcohols, e.g. cholesterol, sterol, cetyl and stearyl alcohols and wool wax alcohols.  The hydrophilic group can also be a carboxyl group as in oleic acid or a carboxylic ester group as in palm oil.  Specified water-soluble ionisable emulsifying agents are the alkali metal salts of the sulphates of higher alcohols and of the esters of sulpho-succinic acids, e.g. sodium lauryl sulphate and dioctyl sodium sulpho-succinate.  The examples describe the polymerisation at elevated temperatures in the presence of per compounds as catalysts of methyl and butyl methacrylates and ethyl acrylate using benzoyl benzoate and dibutyl phthalate as plasticisers.  The products may be made into films and coatings. Specification 358,534 is referred to.

Title: Improvements in or relating to frequency shift telegraph receivers
Inventor: BEARD JOHN VINCENT
IPC: H04L27/14
Filed: 1950-11-03
Abstract: 693,049. Code telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 6, 1951 [Nov. 3, 1950], No. 26947/50. Class 40 (iii). [Also in Group XL (c)] In a frequency-shift telegraph receiving arrangement the output from the frequency discriminator is fed to a channel including in sequence a D.C. restorer circuit, a limiter circuit, a low-pass filter adapted to reduce the amplitude of signals of shorter duration than that of any intelligence-conveying signal element and a " slicer " circuit arranged not to respond to signals substantially below the level of the intelligence-conveying signal elements at the input of the slicer circuit. The signals from the output 1 of the discriminator are fed via condensers 2, 3 to sections A, B of a double-diode V1, the sections being respectively rendered conductive by the positive and negative portions of the wave-form, Fig. 2 (a), to produce wave-forms 2 (b), 2 (c) fed in combination from the centre-point of a resistance 4, 5, as a waveform 2d, to a limiter valve V2. The wave form fed to the limiter valve V2 which may be as indicated in Fig. 3 (e), equivalent to that in Fig. 2 (d), and contains noise pulses N1, N2, produces a substantially square wave-form which contains the noise pulses such as N2, Fig. 3 (f) (not shown), of substantial amplitude between signals representing successive characters. The output of the valve V2 is applied to a valve V3 having a low-pass filter 7 in its anode circuit so that in the wave-form applied to the valve V4 the noise impulses N2 appear with much reduced amplitude, as indicated in Fig. 3 (g). The valve V4 is arranged to slice the applied wave-form so that the noise pulse is eliminated, and the signal output at 8 is a correct replica of the wave-form corresponding to the original or transmitted signal.
