Abstract: 1483936 Douche, bidet or enema apparatus JL MURRAY and FR GARDINER 30 Aug 1974 [31 Aug 1973] 38118/74 Heading A5R [Also in Division Fl] Douche, bidet or enema apparatus consists of a container 12, for douching liquid, e.g. water, closed by cap 14 which supports a housing 60 containing an envelope 100, the housing normally sealing with cap by flanges 84, 86 to prevent exit of the liquid through cap passage 34 to a douche or bidet nozzle 44, the apparatus in use being inverted and a plunger 78, 80 depressed to move the housing away from the cap so allowing the liquid to contact the envelope, the latter containing a first compound, e.g. sodium bicarbonate, to produce with liquid a douching solution, and a second compound, e.g. citric acid to react with the first compound and the liquid to produce effervescence and expel the liquid from the nozzle via passage 34. The housing may also have ports 98 normally sealed by rods 92 attached to the cap and opened on movement of the housing away from the cap by the plunger. The envelope 100, Fig. 7 (not shown), comprises three panels of porous tea-bag paper sealed at their peripheries to define two compartments, one containing the citric acid the other the sodium bicarbonate, one side being sealed with water-soluble cement so that it opens on contact with the liquid to allow the contents out to facilitate their reaction. In modifications, Figs. 8, 9 (not shown), the pouch is perforated or has a fold-over flap sealed with water-soluble cement. The nozzle 44 has a shank 42 to fit in the cap and a groove 50 with apertures 52 therein. If used as a bidet it is replaced by another cylindrical nozzle, Fig. 6 (not shown), having a plurality of apertures in a transverse wall. The sodium bicarbonate may be previously dissolved in the douche liquid and then only a one compartment envelope used.

Title: Data transmission apparatus
IPC: H04L12/54
Filed: 1963-10-07
Abstract: 1,029,938. Telegraphy. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 7, 1963 [Oct. 15, 1962], No. 39368/63. Heading H4P. An apparatus for connection between a line and a processor is used (1) to receive characters in synchronous or start-stop serial code and pass them in parallel synchronous code to the processor, or (2) to receive from the processor parallel synchronous or start-stop signals and pass them to line in serial form. These four modes of operation all use a shift register and include means for storing a signal indicating the length of the character currently being operated on. A control word derived from a memory provides an 11-bit word, a 4-bit word used for pre-setting a counter, a 4-bit word indicating the character length, and a 2-bit tag word which determines the mode of operation. Mode 1, synchronous serial data from line 5. The control word sets counter 3 and the 12 stages of shift register 1 to zero. The tag word is fed to register 19, whereby mode signals SR = 0, YS = 1 are derived. The character length is set on register 2 as a binary number and fed to matrix 24 which gives an output on one of 11 leads, whereby one of the entry gates 7 is enacted. The received serial data therefore passes through this gate to the corresponding stage of shift register 1, a bit being transferred at each time t1. At t2 the bits in register 1 are shifted to the right. At t3, counter 3 steps by one. This operation continues until, when the first bit received has reached stage R1, counter 3 shows the same count as does register 2, whereupon comparator 4 pulses. Thus, at t 4, gate 44 enables exit gates 8. Certain of these gates 8 are masked, however, by an arrangement of AND gates 25 and OR gates 26, so that the only gates passing bits in parallel from register 1 to the processor correspond in number to the character length. The comparator output resets counter 3 to zero so that the next character can be received. Mode 2, start-stop serial data from line 5. The various registers are set as described for mode 1. Now, when the first-recieved bit, the Start bit, reaches stage R1 the Stop bit will be in register 58. When these two bits are detected by unit 14 a pulse is given on SS so that, at t3, the Start bit is shifted out of register 1 and is lost. At t4, all the exit gates 8 (the masking gates being inoperative) pass the contents of register 1 to the processor in parallel. Mode 3, parallel synchronous data from the processor received on line 6, and Mode 4, parallel Start-Stop data from the processor. The operation is substantially similar in both modes. As in modes 1 and 2, the control word sets the various registers. At times t1, the bits of the word in the register 1 are read out serially to line, and when comparator 4 pulses a character is passed via gates 9 at t4, in parallel form, to register 1. This character is then read out, as before, from stage R1 of the register, bits being shifted down the register at times t2.

Emitter followers EF1, EF2 provide the requisite level shifting for connection of logic circuits in cascade. Any changes in the base to emitter voltages of emitter followers EF1, EF2 due to temperature variations is compensated by corresponding base to emitter voltage change of transistor T4 in the supply circuit.

A field effect device with two or more stable states consists of a ferroelectric body having a semi-conductive part constituting the current path between a pair of electrodes and an insulating part adjacent thereto provided with a gate electrode. A preferred embodiment is made from a monocrystal of insulating barium titanate or other perovskite by reducing it throughout to N-type conductivity by a prolonged heating at 600-900 C. in hydrogen and then reconverting the surface layer 6, Fig. 13, to insulating form by a brief oxidation in air. Spaced apertures 8 are then formed in the layer by etching in phosphoric acid through a mask. Ohmic contacts 12, 14 are formed in the apertures by depositing magnesium, covering it with gold, and then sintering in nitrogen. Oppositely disposed aluminium gate electrodes 16, 30 are formed by evaporation. The device exhibits 3 or 4 resistive states according to whether the gate electrodes are of the same or different sizes. One of the gates may be omitted to provide a two stable state device. An alternative way of making such a device is to convert the surface of an insulating body to semi-conductivity by reduction, grind away the surface except on one face, and then provide appropriately positioned electrodes.

Abstract: 1478707 Fat component of a soft dairy spread NEW ZEALAND DAIRY RESEARCH INSTITUTE 25 Sept 1974 [27 Sept 1973] 41760/74 Heading C5C The fat component of a soft dairy spread is produced by a process comprising the steps of fractionating a milkfat or a milkfat-containing substance into three fractions: (1) a fraction in which substantially all the milkfat is solid at 20‹ C. melting increasingly at higher temperatures; (2) a fraction in which substantially all the milkfat is solid at 0‹ C. and liquid at 20‹ C.; and (3) a fraction in which substantially all the milkfat is melted at 0‹ C.; and blending fractions (1) and (3) in proportions such that the ratio of liquid fat content to solid fat content of a soft dairy spread including such fat content remains substantially constant over a temperature range of 5‹ to 22‹ C. The preferred form of fractionation is solvent fractionation, e.g. liquid extraction, leaching or solvent crystallization. Suitable solvents are propan-2-ol, acetone, ethyl acetate, hexane and petroleum derivatives. The soft dairy spread may comprise a fraction of milkfat which is substantially solid at 20‹ C. melting increasingly at higher temperatures, blended with a further fraction of milkfat which is substantially liquid at 0‹ C. so that the ratio of liquid fat component to solid fat component remains substantially constant over a temperature range of 5‹ to 22‹ C. and mixed with water, salt and solids-not fat. The soft dairy spread may be prepared by taking the fat component in which the weight ratio of fraction (1) to fraction (3) is about 1 : 3, adding water, salt and solids-not fat, and mixing.
