Title: Improvements in or relating to carburetters for internal combustion engines
IPC: F02M7/18
Filed: 1938-02-12
Abstract: 498,434. Spray carburetters. NAVROTZKY, N. DE, and SOC. D'ETUDE ET D'EXPLOITATION DES PROCEDES DE NAVROTZKY S.E.N. Feb. 12, 1938, No. 4449.

Title: Improvements in and relating to logical circuits
IPC: H03K19/16
Filed: 1960-02-09
Abstract: 910,765. Circuits employing bi-stable magnetic cores. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 9, 1960 [Feb. 9, 1959; June 30, 1959], No. 4493/60. Class 40 (9). A bi-stable core comprises an input winding fed with pulses tending to establish a first remanent state, a condenser charged by the input pulse, discharging at the end of the pulse to tend to establish a second remanent state, the core also having a hold winding coupled to an output winding and operating when the core switches from its second to its first state to maintain the core in its first state after the termination of the input pulse provoking the change. In the binary counter, Fig. 2, all the cores 11 ... 14 are initially in the " O " state. A first positive pulse on the input 16 tends to drive core 11 further into the " O " state and therefore has no effect. The pulse however charges capacitor C 1  which discharges through the winding 11a and resistor R 1  after the pulse ceases. This drives core 11 to the " 1 " state. The resulting output voltage from winding 11b however is of such a voltage as to maintain transistor T 1  (and also diode D 1 ) cut off. The next pulse on input 16, besides charging C 1  restores core 11 to the zero " O " state, the resulting output from winding 11b being such as to charge condenser 11e positively. This enables transistor T 1  to conduct, the collector current through winding 11c being such as to maintain core 11 in the " O " state. The condenser 11e is arranged to have a sufficiently large discharge time to hold transistor T 1  conducting for the whole of the discharge time of condenser C 1  (after the cessation of the second input pulse) thereby preventing the latter from causing core to go to the " 1 " state at this time. It is thus seen that transistor T 1  conducts once for every two input pulses applied to terminals 16. The transistor T 1  serves as the input to a further -2 stage 12 operating in a similar manner; and so on. Output windings 11d. . . 14d may be arranged with suitably poled rectifiers to give outputs either on the change of state of the associated core from 0 to 1 or vice versa. Parallel read-out can be effected by energization of windings 11r ... 14r.

Title: Improvements in reaction of acetals and alkylene oxides
IPC: C07C43/30
Filed: 1953-02-24
Abstract: Alkoxyalkyl aliphatic acetals are prepared by reacting an aliphatic acetal having the general formula <FORM:0734371/IV (b)/1> wherein R1 is alkyl or alkoxyalkyl and R2 is hydrogen, alkyl, alkoxyalkyl or cycloalkyl, with an alkylene oxide at a temperature between 0 DEG and 60 DEG  C. in the presence of a Friedel-Crafts type of catalyst. The preferred acetal reactants contain not more than 4 carbon atoms in the residue of the aldehyde group and in the residue of each alcohol group; the alkylene oxide also preferably has not more than 4 carbon atoms. Products having up to 4 or more oxy-alkylene groups in the molecule may be formed.  Suitably, the alkylene oxide is added to the stirred acetal containing, say, 0.005 to 1 part of catalyst by weight per 100 parts of reactants.  Specified acetals are those derived from on the one hand acetaldehyde, propionaldehyde, butyraldehyde, 2-ethyl butyraldehyde, hexaldehyde and 3-methoxy butyraldehyde and, on the other, methanol, ethanol, propanol, 2-propanol, 2-methoxy-ethanol, butanol and 2-ethyl-butanol.  The use of formals is also mentioned.  Alkylene oxides specified are ethylene oxide, 1 : 2-propylene oxide, 1 : 2-butylene oxide, 2 : 3-butylene oxide, butadiene di-epoxide or mixtures of these. Suitable catalysts include aluminium chloride, boron trifluoride, ferric chloride and zinc chloride.  According to examples: (1) ethylene oxide and acetaldehyde diethylacetal are reacted to give 1-ethoxy-1-(2-ethoxyethoxy)-ethane and 1,1-di-(2-ethoxyethoxy)-ethane; (2) ethylene oxide and dimethyl butyral are reacted to give 1-methoxy-1-(2-methoxyethoxy)-butane; (3) ethylene oxide and 1,1-di-(2-methoxyethoxy)-ethane are reacted to give 1-(2 - methoxyethoxy) - 1 - (2 - b  - methoxyethoxyethoxy)-ethane; (4) propylene oxide and acetaldehyde diethyl acetal are reacted to give 1 - ethoxy - 1 - (2 - methyl - 2 - ethoxyethoxy) - ethane and 1 - ethoxy - 1 - (1-methyl-2-ethoxyethoxy)-ethane, the catalyst in each case being BF3 in ethereal solution.

Abstract: 1,190,571. Mixing liquids in proportions. BRITISH UNITED SHOE MACHINERY CO. Ltd. 4 May, 1967 [5 Feb., 1966], No. 5137/66. Heading B1C. [Also in Divisions F1 and F2] The constituents of a polyurethane mixture are supplied either through valves 42, 44 to a mixing head or through valves 43, 45 for recirculation to the storage containers 13, 14, the resistance of the flow parts being the same in each case so that there is no change in the ratio of the constituents on change over; the resistance is equalized by the values 42, 43, 44, 45 being of the same design (see Fig. 4, not shown, and Division F2). The mixing head, Fig. 5, is in two pivoted halves 1,14, 115 having cooperating grooves 122, 123 in their meeting faces forming in the closed position a mixing chamber in which the constituents are supplied through passages 152, 154. In another embodiment (Fig. 8, not shown) the mixing chamber is a bore (223 to which constituents are supplied through radially opposed passages (253 and 254, see also Fig. 7, not shown). A piston (202) has an axial bore (204) with outlets (.207) through which cleansing fluid is supplied; on completion of a mixing operation the piston (202) expels the mixture and washes the bore. The pumping apparatus (see Fig. 2, not shown) has a double acting hydraulic powered cylinder (31) and two single acting cylinders (17, 24) for the constituents. As depicted the piston rods of cylinders (17, 31) are pivoted to a rocking beam (88) by blocks (93, 94) slidably adjustable along the beam to alter the pumping ratio, and the piston rod of the cylinder (24) is connected to, and moves with, that of the cylinder (31) by means of a T-piece (99) fitting in recesses (77, 97). The cross-head blocks (91, 96) can be interchanged so that the cylinders (17, 31) act together and the cylinder (24) acts directly on the beam (88), which enables the ratio of the amounts dispensed by the pistons to be altered from 2:1 to 1:2; as depicted however, cylinder (17) has a crosssection twice that of cylinder (2x) so that the ratio of the constituents may be varied between 4:1 and 1:4.
