Title: Multidirectional lever switch
IPC: G05G9/047
Filed: 1970-07-17
Abstract: 1321440 Mechanical switches; retractive switches TELEMEOCANIOA ELETTRICA OFFICINE MECCANICHE RILINITE SpA 17 July 1970 [18 July 1969] 34734/70 Heading H1N A multidirectional lever switch has its lever 18 mounted in a ball joint 28 by sphere 26, has a spring 30 between sphere 26 and positioning cap 32 and has a number of mioroswitches (only microswitches 13, 14, 15, 16 and 40 being shown) operable by a block 37 slidable in the arms 38 of a first cross 39 and linked to lever 18 by oscillating joint 36. The microswitches operated are determined by the profile of the underside 44 of block 37 and by the shape of a second cross 33 on which runs positioning cap 32, the shape of cross 33 being such that when cap 32 is in the central position (as shown) two positions are offered to cap 32 for each of the four arms 38 of the cross 39. To operate the switch, cup 20 is pulled upwards which frees shank 21 of cup 20. from member 25 and pulls upwards stem 22 within hollow lever 18 by means of pin 23 in slot 24 in the wall of lever 18. When stem 22 is pulled upwards its lower end 42 releases pushbutton 41 of microswitch 40 to send a signal. Lever 18 can then be tilted by means of knob 17 to either side or forwards or backwards. Assume knob 17 is tilted to position A3. Block 37 depresses pushbutton 48 of microswitch 14 and cap 32 rides up the right hand inclined surface 34. If knob 17 is then released, spring 30 in conjunction with surface 34 returns cap 32 and lever 18 to its central position. If knob 17 is moved to position A1, cap 32 rides into the right hand retaining seat 35 so that when the knob 17 is released cap 32 remains in seat 35 and both pushbuttons 48 and 50 of microswitches 14 and 13 remain depressed. Lower surface 44 of block 37 can be shaped, for example having a hollow centre so that in position A1 only pushbutton 50 is depressed. Cross 33 may have different shapes. With the shape shown in Fig. 1 (repeated in Fig. 2 (not shown)) there are four retractive and four latched positions. With the shape in Fig. 3 (not shown) the surfaces 34 and 35 are reversed so that the switch is latched in position A3 and not latched in position A1 giving four latched and four retractive positions but reversed from Figs. 1 and 2. With the shape in Fig. 4 (not shown) there are eight retaining seats giving eight latched positions.

Title: Polymerization process
IPC: C08G63/78
Filed: 1962-09-13
Abstract: Polymerization is carried out in a liquid medium present as a continuous phase to obtain a condensation polymer which is insoluble in the liquid medium, the reaction mixture including a precursor condensation polymer present as particles which are dispersed in the liquid medium, and within the body of which a condensation reaction takes place to form polymer molecules of higher molecular weight, the liquid medium containing a dispersing agent for the particles when the latter are liquid or a swelling agent for the particles when the latter are solid.  The precursor polymer may be formed in the liquid medium and the condensation continued to form a polymer of higher molecular weight.  Block or graft polymers may be obtained by the process if at least one of the reactants is a reactive condensation polymer.  The liquid medium may be a hydrocarbon, halogenated hydrocarbon, ether, acetal, aldehyde, ketone, nitrile, tertiary amine, nitro compound or water.  The dispersing or swelling agent includes ethers, ketones, heterocyclic compounds, certain polymers, and polyethylene glycols.

Title: Improvements in and relating to the preparation of an olefin oxide
IPC: B01J19/24
Filed: 1961-09-29
Abstract: In the non-catalytic, vapour phase production of C2-C4 alkylene oxides, a saturated C2-C4\t hydrocarbon and 4-14% by volume of oxygen are passed into a reaction zone, maintained isothermally at 425-575 DEG C. at a pressure of 20-150 psig, with mixing so that a homogeneous mixture of reactants and reaction products is formed, the contact time being 0.07-1.5 secs. The reaction zone is maintained in an isothermal condition by removing heat from the reaction zone by heat transfer or preferably by adding the feed gases and any recycle gases to the reaction zone at a temperature lower than the reaction temperature in such a way that the relatively cold incoming gases will intimately mix with all the reactants and reaction products, absorb the heat liberated by the oxothermic oxidation and so maintain the reaction temperature constant.  The feed gas mixture contains oxygen and C2-C4 hydrocarbon and preferably also contains the corresponding C2-C4 olefinic hydrocarbon and diluent gas e.g. CO, He, N2 or CO2. The preferred molar ratio sat. hydrocarbon:olefinic hydrocarbon is 1:2-10:1, more preferably 3:1-4:1. Preferred contact times are 0.10-0.6 secs. Under these conditions the optimum yield of alkylene oxide (mg/l product gas) and optimum reaction efficiency (i.e. lbs alkylene oxide/100 lbs H/C reacted) are obtained with a minimum production of acetaldehyde and other by-products.  In Examples 1-18, 20-33 Table 4 propylene oxide is formed when a mixture of propylene and propane is oxidised under the conditions set out. (19) Propylene oxide is produced from propane only; (34) Propylene oxide is produced by oxidising 62% by vol. propane, 20% by vol. propylene with 8% oxygen and 10% CO as diluent. When the reaction reaches a steady state the effluent gases from the reactor are passed through a series of water cooled condensers into a trap which removes high boiling by-products and formaldehyde hydrate, and then analysed by vapour phase chromatography. Examples 37-41 describe the oxidation of ethane-ethylene mixtures to ethylene oxide which is extracted as in Example 34. Four suitable reaction vessels are described.

Abstract: 1400521 Automatic control of speed HONEYWELL INFORMATION SYSTEMS ITALIA SpA 28 July 1972 [26 Aug 1971] 35448/72 Heading G3R A motor 16 driving a tape recorder capstan 5 is provided with an automatic speed control at its normal running speed and provision where during acceleration a constant current is applied to the motor. In the system described the motor speed is measured by an optical pulse generator which supplies pulses through limiting amplifier 63 to pulse generator 64 which supplies short duration pulses to reference monostable circuit 65 which is triggered by the incoming pulses to produce error pulses whose duration represents the difference between the required and actual motor speed. Each pulse is converted into a voltage by capacitor 68 or 74 and the voltage applied through either resistor 24 or 25 to the input of control amplifier 17. On starting, the current through the motor will produce in series resistor 29 a voltage e 1  at point 90 on the voltage divider shown in Fig. 4 which is outside a predetermined value and causes one opposite pair of diodes to conduct thereby applying a constant voltage at input 19 of amplifier 17. Direction signals are applied through logic circuitry to the terminals 73, 75 to control which capacitor 68, 74 is used. This logic signal is arranged to apply a reverse direction signal to stop the motor.
