Abstract: Polyesters or polyetheresters are made by reacting an anhydride of a dicarboxylic acid with a monoepoxide in the presence of a catalyst which is an organometallic compound of formula RnM, where M is a metal of Group I, II or III of the Periodic Table (e.g. Li, Mg, Zn or Al), R is a hydrogen or halogen atom, or an alkyl, cycloalkyl, aryl, aralkyl, hydroxy or alkoxy group at least one of the R radicals in the catalyst molecule being an alkyl, cycloalkyl, aryl or aralkyl group, and n is 1, 2 or 3 depending on the valency of the metal M. The monoepoxide has the formula <FORM:1045469/C3/1> or <FORM:1045469/C3/2> wherein R1, R2 and R3 are each a hydrogen or halogen atom, or an alkyl, vinyl, phenyl, tri-fluoromethyl, fluoromethyl, chloromethyl, bromomethyl, allyloxymethyl or phenoxymethyl radical, or R1 and R2 together with the carbon atoms to which they are attached form a substituted or unsubstituted carboxylic ring. The dicarboxylic anhydride preferably has the formula <FORM:1045469/C3/3> or <FORM:1045469/C3/4> wherein R4, R5, R6, R7, R8 and R9 are each a hydrogen atom or an alkyl or aryl group or has the formula <FORM:1045469/C3/5> wherein the carbocyclic ring may contain as substituent a halogen atom or an alkyl, aryl, aralkyl group, may be bridged by an endomethylene group and may contain 1, 2 or 3 carbon-to-carbon double bonds.  The reaction mixture may also include 0.5 to 5 mols, per mol of the organometallic compound, of a compound containing at least one active hydrogen atom (e.g. water, an alcohol, an amine or a thiol). Reaction is effected at -78 DEG  to 200 DEG  C. in the presence or absence of an organic solvent. Examples describe the reaction of (1)-(3), (13) and (15) phthalic anhydride and epichlorohydrin; (4), (14) and (16) phthalic anhydride and propylene oxide; (5)-(11) endo-cis-bicyclo-(2:2:1) -5-heptene-2:3-dicarboxylic anhydride and propylene oxide; (12) succinic anhydride and propylene oxide; (17) and (18) phthalic anhydride and ethylene oxide.

Abstract: 621,525. Inductor alternators; supply systems depending on variable-speed generators; automatic regulation. MANDL, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 29, 1946, No. 35504. [Classes 35 and 38 (iv)] Heating resistors for the different compartments of a railway coach are individually supplied from separate windings of a common axle-driven inductor alternator, the circuit arrangement and alternator construction preferably being such that a substantially constant voltage is applied to any heater in circuit irrespective of the number in use and of variations in alternator speed and excitation. For this purpose the reactance of each winding may be high in relation to the resistance of the heater; or the heater may be fed through a condenser. The plurality of output circuits may be obtained by providing on the machine several separate, but commonly excited, stators, each having a two-phase winding. Alternatively, a heteropolar machine having a single- or two-phase winding on each pole may be employed. The machine may be excited by a battery and worked in the saturated range to render the output voltage independent of excitation; or excitation may be provided by a further output winding which feeds the excitation winding through a rectifier and choke.

Title: Improvements in or relating to clutches for mechanically propelled vehicles

Filed: 1961-10-05
Abstract: 999,643. Clutch control. ROBERT BOSCH G.m.b.H. Oct. 5, 1961 [Oct. 6, 1960], No. 35878/61. Heading F2L. The electromagnetic powder clutch control circuits described in Specification 993,631, in which a clutch winding 35 is supplied with current pulses derived from the engine ignition system, is modified by the inclusion of a resistor 121, which is inserted into the surge circuit of the clutch winding at vehicle speeds above 15 k.p.h. At speeds below this value the resistor 121 is shorted through a centrifugal switch 90 (which opens above 15 k.p.h.) and a rectifier 122. The clutch is thus de-energized rapidly during gear changes at speeds above 15 k.p.h., while for starting the de-energization time is relatively large. In order to facilitate push-starting of the vehicle a capacitor 128 of at least 0.5 ÁF and preferably 10 ÁF, is connected in parallel with a resistor 83 which is located between the positive lead 51 and the base of the switching transistor 82. During such starts, the switch 90 opens when 15 k.p.h. is exceeded, causing the output transistors to be conductive and the clutch to engage, thereby braking the vehicle and causing the switch 90 to close. After closing of the switch 90, the capacitor 128 maintains for about half a second the potential of the base of the transistor 82 at the value effective when the switch is open and thus delays de-energization of the clutch. Specification 993,632 also is referred to.

Title: System for printing or displaving data
IPC: G06T9/00
Filed: 1975-09-01
Abstract: 1504607 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 1 Sept 1975 [19 Dec 1974] 35923/75 Heading G4H A data printing/displaying system uses a data store holds codes representing characters or symbols, the codes being derived by dividing each character or symbol into a plurality of columns and storing a plurality of coded position values of non-mark/mark and mark/non- mark transitions along the length of each column, except for adjacent columns of identical position values for which only the values for one of these columns and the number of identical columns are stored, and a coded value defining that a column has at least one different position value from the preceding adjacent column. As disclosed, the store is a font store in a dotmatrix printer using a column of print electrodes and is addressed via an index table by the character to be printed. The transition values for a column are decoded to set bits in a register which sets bits in another register via a chain of XOR gates which fill in the area of mark, the latter register controlling the column of print electrodes a number of times determined by loading the "number of indentical columns" value into a counter and decrementing to zero. The list of coded values in the font store for a character starts with a coded value specifying the number of such values, this number being loaded into a counter and decremented to zero to call for the next character. A character may be printed higher or lower on the document by adding a positive or negative stagger value to the transistion values prior to decoding. To deal with the case where the character bridges two lines of print, a flip-flop is set by a non- positive output from the adder to insert a "1" into the low end of the chain of XOR gates. Similarly, a large character bridging several lines can be printed. Characters can be printed backwards (during printhead return) by reading the data from the front store backwards. A negative print is achieved by inversely initializing the flip-flop.
