Title: Improvements in laundry listing machines
IPC: B41K3/08
Filed: 1947-08-28
Abstract: 647,263. Typewriters &c. NATIONAL MARKING MACHINE CO. Aug. 28, 1947, No. 23894. Convention date, Sept. 23, 1946. [Class 100 (iv)] A laundry listing mechanism of the kind employing a number of rotatable type wheels which are set by being selectively advanced step-by-step and an impression device to make an imprint from the type wheels, comprises a resetting device restoring simultaneously all displaced type wheels and a locking mechanism actuated by the printing device to prevent operation of the type advancing mechanism and released by the operation of the resetting device after the type wheels have been restored to normal position. The setting, resetting and imprinting devices are constructed as described in Specification 635,087. The cams 300, Fig. 3, corresponding to cams 39, 40 of Specification 635,087, sixty of which are mounted freely on a transverse rod 35 and actuated by the keys 34, have a T-shaped slot therein through which passes a looking rod 310. During normal operation of a key the cams actuate the typewheel advancing mechanism 51-59, the rod 310 passing freely in the arcuate portion 302 of the slot concentric with the rod 35. The rod 310 extends through the side frames of the machine, Fig. 4, and terminates in collars 313 connected to armatures 315 working in solenoids 316 attached to the side frames 20 of the machine. The rod 310 is normally urged to the position shown in Fig. 3 by plungers 306 spring mounted in sockets 304 in the framework, but when the impression platen 109 is actuated, electrical contacts 317-319 are made, energizing the solenoids 316 which draw the bar 310 into the stem portion of the slot 303 and thereby locks all the cams 300 against operation. The solenoids 316 are maintained operative by a holding relay until a resetting handle 136 of the type-wheel resetting-device is fully rotated, whereupon a radially-extending finger 153, Fig. 5, integral with a member 144 fast on the resetting shaft 46, engages a switch 320 to open a pair of normally closed electrical contacts and thus break the circuit to the holding relay. A lamp is in parallel with the solenoid coils to give an indication to the operator that the keyboard is locked.

Title: Moulds for encapsulating
IPC: B29C33/00
Filed: 1975-06-04
Abstract: 1508324 Mould for encapsulation CIBAGEIGY AG 12 May 1976 [4 June 1975] 24062/75 Heading B5A A component 13 (e.g. a coil, resistor or ceramic capacitor) is encapsulated in a thermosetting resin within a mould comprising a rigid outer casing 1-3 defining a mould cavity, and at least one pair of opposing flexible plugs 7/8 that grip the component between them. The plug material (e.g. nylon, PTFE, polyethylene, flexible thermosplastics polyurethane, polypropylene or silicone rubber, perhaps embedding metal portions) has a higher coefficient of expansion than that of the outer casing (e.g. aluminium, iron, steel or an epoxide resin with a mineral, aluminium or iron filler). The outer casing comprises two sections or three 1-3 and metal plates 11/12, held together by bolts 4/5 or toggle catches. At least one plug 8 is movable inwardly by a screw 9 and aluminium disc 10, and several components 13 can be supported simultaneously by several pairs of plugs. In use, a component 13 is held by the plugs 7/8 in the silicone release agent coated casing 1-3, which is heated. The mould is evacuated, and a heated thermosetting resin (e.g. phenolformaldehyde, polyurethane, alkyd, polyester, silicone or epoxide resin with colouring, filler and curing agent) is sucked in through holes 14/15. After curing in the mould under heat, the holes in the encapsulated component made by the plugs 7/8 are filled or used for contacts.

Title: Data transmission system
IPC: H04L25/03
Filed: 1976-06-10
Abstract: 1503083 Setting transversal equalizers INTERNATIONAL BUSINESS MACHINES CORP 10 June 1976 [10 July 1975] 24141/76 Heading H4R In an arrangement for determining the coefficients of a transversal equalizer prior to transmission of data a specific periodic binary pseudo random sequence of length L is transmitted and the coefficients derived by correlation technique. The specific sequence is derived by selecting a sequence Ui having the characteristics where and from this sequence a second sequence V i  is derived where and the sequence V i  having the characteristics where the sequence V; is the transmitted sequence which gives rise to a sequence x i  at the receiver, which is correlated with the sequency V i  to determine the equalizer coefficients. As described Fig. I (not shown) the equalizer is put into a training mode prior to transmission in which the sequence V i  stored in a shift register (10) is transmitted and at the receiver the received signal x i  is applied to a coefficient generator (16) to derive the multiplier coefficients for the transversal equalizer (18). After the coefficients have reached their optimum value  normal data transmission takes place with the equalizer coefficients either fixed or adaptively varied. In the preferred arrangement for deriving the equalizer coefficients the relation is used where Copt is the theoretical optimum equalizer coefficients, B is the autocorrelation matrix of the transmission channel impulse response and R is the inversed column vector the terms of which are samples of the impulse response of the transmission channel, where inversed means that the first term of the vector is the last sample of the impulse response. To determine the samples of the channel impulse response use is made of the relation where the impulse response exists for the period N 1  to N 2 . However due to the choice of transmitted sequence V i  is null for all terms except when n=j where A 0 <SP>1</SP> = L and so and thus by correlating samples of the received signal X i  with stored samples of the transmitted signal V i /L, as shown in Fig. 4, for a sequence of length L=3, the impulse response samples r -1 , r 0  and r 1  are obtained. The autocorrelation matrix B of the impulse response is implemented by the arrangement of Fig. 5 (not shown) to obtain the values B 0 , B 1 , B 2 , which are used in the equipment of Fig. 6 to obtain the optimum equalizer coefficients C -1 , C 0 , C 1 . Since the solution of the equation by inversing the matrix B would require large calculation power the equation is solved by an iterative adjustment method defined by the relation where C<SP>n</SP> and C<SP>(n-1)</SP> are coefficient column vectors at the n and n - I iteration. In Fig. 6 the coefficients C -1 , C 0  and C 1  are held in stores 48, 49, 50, and the apparatus performs the calculations according to the expansion of at the convergence point where C<SP>n</SP>=C<SP>(n-1)</SP> then BC<SP>nr-1</SP>=R or and the values of Copt are transferred to the equalizer to set the coefficients.

Title: Treatment of vitamin e-active material
IPC: C07D311/72
Filed: 1950-10-05
Abstract: The invention comprises compounds of the general formula <FORM:0676853/IV (b)/1> (wherein X represents hydrogen, a methyl group or a hydroxyalkyl group and Y a hydroxyalkyl group), the preparation thereof by nuclear hydroxyalkylation of tocopherol material initially having at least one aromatic hydrogen atom on the benzenoid nucleus, and a process for enhancing the vitamin E activity of tocopherol material by carrying out the foregoing hydroxyalkylation and then reducing the hydroxyalkyl group to the corresponding alkyl group. The hydroxyalkylation is preferably effected by the action of an alkyl aldehyde (especially formaldehyde) in the presence of an alkaline material (e.g. a free base, an alkaline salt, an alkaline oxide or a basic alcoholate), advantageously in an organic solvent (e.g. an aliphatic alcohol) and with the passage of an inert gas through the reaction mixture, whilst the subsequent reduction may be carried out with zinc dust and hydrochloric acid.  Suitable starting materials are b - and g -tocopherol (which by hydroxymethylation and reduction yield a -tocopherol), d -tocopherol (which similarly yields a - or b -tocopherol), or also mixtures of these compounds, or concentrates (e.g. from vegetable oils) containing them.  In an example, a g -tocopherol concentrate is warmed with aqueous formaldehyde in the presence of ethanolic caustic potash while bubbling nitrogen through the mixture, the resulting 5-hydroxymethyl-g -tocopherol is isolated by extraction with ether and evaporation of the extract, and is then dissolved in isopropyl ether and reduced with zinc dust and concentrated hydrochloric acid.  The formaldehyde may be replaced by acetaldehyde or higher aldehydes and the caustic potash by caustic soda or potassium carbonate.  Specification 639,011 is referred to.
