Abstract: 942,354. Universal joints. DODGE MANUFACTURING CORPORATION. Dec. 28, 1961 [March 9, 1961], No. 46516/61. Heading F2U. In a universal flexible coupling wherein a resilient annular member 20 of arcuate crosssection is clamped to flanges 30 secured, as by keys 114, on driving and driven shafts 12, the annular member is split at 58 to facilitate assembly and comprises side walls 52 and axially extending beads 56, the flanges comprise radial faces 40, cylindrical surfaces 38 and tapered abutments 88, and collars 32, each comprising two halves, are radially contracted, by screws 74, to engage the annular member and, by correspondingly tapered surfaces 90, the tapered abutments 88, so as to radially and axially clamp the beads and side walls of the annular member against the surfaces 38 and the faces 40 respectively. The flanges may be circumferentially continuous and secured on their shafts by keys and setscrews (Figs. 8, 9, not shown), or, as shown, split at 44 to permit shaft-gripping contraction thereof by the collars. The annular member 20 is of rubber or rubber-like synthetic material with layers 62 of nylon or the like embedded therein. The side walls or the beads or both may be thickened, and the beads may-have hard cores. The collars 32 preferably have peripheral protrusions 96 to increase the clamping action. To prevent relative rotation between the flanges and the collars inserts 100 are seated in aligned slots 104 of the flanges and collar halves and retained by setscrews 108, the tightening of which locks the collars in position and, as shown, the flanges on their shafts. In Fig. 7 (not shown), the collars extend inwardly so that when contracted they engage the flange cylindrical surfaces 38 to limit the compression of the annular member and simultaneously apply sufficient pressure to secure the split flanges to their shafts. The driving and driven shafts may be of different diameters, and straight or tapered.

Title: Method for sterilizing in particular food products and apparatus  to perform the method
IPC: A23L3/00
Filed: 1973-10-05
Abstract: 1438029 Sterilizing foods ETABS JOSEPH LAGARDE 5 Oct 1973 [9 Oct 1972] 46539/73 Heading A2D A method for sterilizing containers particularly containers holding food products, comprises placing the containers in an autoclave, injecting steam into the autoclave to establish a temperature higher than the sterilization temperature, reducing this temperature to a value equal to or just above said sterilization temperature without reducing the autoclave pressure, and subsequently cooling the inside of the autoclave. The temperature reduction may be achieved by the introduction into the autoclave of spurts of compressed air, and the evacuation, in spurts, of the resulting air-steam mixture. Compressed air and water may subsequently be introduced in spurts. The containers may be cooled by spraying water into the autoclave. The method may be carried out in the apparatus shown in the accompanying Figure, which comprises an autoclave 1 provided with a steam inlet valve 3, a compressed air inlet valve 6, a water injection valve 9 and a cooling water injection valve 10. The air-steam mixture may be evacuated via valve 8. The steam is distributed in the autoclave by means of perforations 5. A blower 7 enhances the mixing of the air and steam in the autoclave. Water, for cooling the containers after sterilization, is sprayed into the autoclave via nozzles 12.

Title: Cyclic fluoroolefins
IPC: C25B3/28
Filed: 1970-10-02
Abstract: 1330169 Cyclic perfluoro-olefins AIR PRODUCTS & CHEMICALS Inc 2 Oct 1970 [7 Oct 1969] 46897/70 Heading C2C [Also in Division C7] C 6-10  cyclic perfluoro-olefins (including the novel compounds decafluoro-3-methylcyclopentene, decafluoro-4-methylcyclopentene, and octadecafluoro - 4 - (n - butyl) - cyclohexene) are obtained by reacting at temperatures between 40 and 200 C. a 5- or 6-membered ring perfluorinated cycloalkyl carboxylic acid or acid fluoride with a reagent selected from organic acids, salts of organic acids, alkanol sulphate salts, aqueous basic solutions and molecular sieves. Suitable reagents include isodecanoic acid, valeric acid, sodium lauryl alcohol sulphate, sodium neopentyl alcohol sulphate, potassium laurate, KOH, NaHCO 3 , anhydrous sodium acetate and 3A molecular sieve. The 5- or 6-membered ring perfluorinated cycloalkyl carboxylic acids or acid fluorides used as starting materials can be obtained from the C 1  to C 4  alkyl substituted or unsubstituted benzoic acids or halides by electrolysis of a solution thereof in anhydrous liquid hydrogen fluoride using an iron-cathode nickel-anode cell operated at about +16 C. with an applied voltage of 5 to 7À7 volts. The perfluorinated acid fluoride which settles to the bottom of the cell with fluorinated by-products can be hydrolysed with water to the perfluorocyclic acid which is then recovered by fractional distillation. Thus benzoic acid yields perfluorocyclohexane carboxylic acid fluoride which can be hydrolysed to the acid, and 2- and 3-methylcyclopentane carbonyl fluorides are also formed. o-Toluic acid yields perfluoro-2-methylcyclohexane carboxylic acid, m-toluic acid yields perfluoro 3-methyl cyclohexane carboxylic acid, p-toluic acid yields perfluoro-4-methylcyclohexane carboxylic acid, and p-(n-butyl) benzoic acid yields perfluoro-4-(n-butyl) cyclohexane carboxylic acid.

Title: Implicit beam angle control for a frequency scanning radar system
IPC: H01Q3/22
Filed: 1970-10-06
Abstract: 1318762 Aerials; automatic phase control INTERNATIONAL STANDARD ELECTRIC CORP 6 Oct 1970 [13 Oct 1969] 47464/70 Headings H3A and H4A A transmission line is used as a reference element in effecting corrections of the frequency of an RF generator which energizes a frequency scanned aerial array. The line is connected at one end to the RF generator and it is constructed to be a plurality of wavelengths long at frequencies within the programme of said generator, so that there should be a predetermined phase change at its other end for each frequency change in said programme. Means are provided for comparing the phases at the generator and at the said other end of the line, and a further means applies any necessary corrective signal to the RF generator, thereby effecting phase-lock loop control. As described, an aerial array comprises a plurality of spaced apart radiating elements which are fed by means of a folded or serpentine waveguide receiving power from amplifiers connected to an output 24 of a microwave energy distributer 23. Power is also supplied from the distributer 23 to the input 7 of a directional coupler 6, and, on a lead 25, to receiving equipment. The directional coupler 6 has an output connected to one end 4 of a reference serpentine line 2 and has another output connected to one input 9 of a magic-T hybrid 8. The other end 5 of the serpentine line 2 is connected to the other input 10 of the hybrid 8 through a controlled phase shifter 17. A backward wave oscillator 22 is connected to the input of the distributer 23, and scanning of the beam from the aerial array in steps is effected by incremental changes of frequency of said oscillator. For this purpose a master timing control signal applied at a terminal 18 triggers a staircase voltage generator 19 which is connected to the helix driver 21 of the oscillator 22. The driver 21 also receives a vernier control voltage derived from the reference line 2, said line being designed to be a whole number of wavelengths in length at each scanning frequency step, and to have the same electrical length temperature characteristics as the array feed waveguide. The reference line and the feed waveguide are thermally associated, for example, by mutual connection to a common heat sink, or by being enclosed in a common radome. Assuming the phase shifter 17 at zero setting, the two outputs 11, 12 from the hybrid 8 are indicative of the phase difference between the input and the output of the line 2. Detectors 13, 14 remove carrier frequency and provide bipolar error signals to an amplitude comparator 15. If said input and output are not in phase, a correction voltage is applied on a line 16 to the driver 21, and the frequency is correspondingly adjusted. The purpose of the phaseshifter 17, which is controllable by a driver 20, triggered by the master signal from the terminal 18, is to provide a means of introducing offsets into the frequency scan programme, such as would be required for an interlace scan.
