Title: Improvements in or relating to a pulsator device for milking machines
IPC: A01J5/12
Filed: 1971-08-05
Abstract: 1299036 Pulsator for milking machines W KRAUT [trading as BIZERBA-WERKE WILHELM KRAUT KG] 5 Aug 1971 [14 Aug 1970] 36843/71 Heading AIM In a pulsator for a milking machine, a milk collecting chamber 29 is hermetically separated from a control device. The device comprises a slide valve 8 connected to, and reciprocated by, a flexible diaphragm 9 separating chambers 11, 12 which are alternately at elevated and reduced pressures. Hoses 2, 3 are continuously connected to high and low pressure sources respectively, hoses 4, 5 being connected to a milking cup. In operation, when the valve 8 is in its upper position hoses 2, 4 are connected and high pressure is supplied, via passage 22, to valve 28 closing milk collecting duct 6. The chamber 29 has a permanent restricted connection to the atmosphere via passages 41, 42, 43. In the lower position of the valve 8, as shown, hoses 3, 4 are connected, the valve 28 rising due to a reduced pressure in passage 22. This partial vacuum prevails in the duct 6 since air only slowly leaks into the chamber 29 due to the small size of passages 41, 43. Thus milk is drawn up the hose 5 into duct 6. In. a modification, the passage connecting the chamber 29 to the atmosphere is closable by a valve separate from but which may be controlled by the control device. An air filter may be included and upstream of the filter may be a pressure source to compensate for any pressure loss.

Filed: 1975-09-12
Abstract: 1525612 Radiography THOMPSON-C S F 12 Sept 1975 [13 Sept 1974] 37689/75 Heading H4F The invention relates to a television system for a computed tomography system in which a crosssection of a body is to be displayed in a pattern of opacities to radiation related to elements of a notional matrix overlying the cross-section, and the television system is capable of displaying those elements with opacities lying within an adjustable range centred on a selectable value to be displayed distinctly from all other areas, e.g. with different contrast and/or colour. For example, Fig. 9 shows a computed tomography signal processing system comprising a data store 4, a computer 9 and a digital-to-analogue converter 12 which applies a modulating voltage to the control grid of a c.r.t. 31. The opacity range and central value are applied to register 14 and comparators 131 and 132 determine whether a signal value from store 4 lies within or outside the range. If it is not within the range, gate 40 is blocked and inverters 41, 44 and gates 34, 39 apply a voltage V, to the anode 32 of the c.r.t. such as to give a green display with a contrast determined from a register 11. If the signal lies within the specified range, however, anode voltage V 2  is applied by gate 35 so as to give a red display, the contrast value then being that from register 45 because gate 46 is activated. In monochrome displays, the areas outside the range of interest can be displayed as all white or all black.

Title: Pneumatic square wave generator
IPC: F15C3/04
Filed: 1971-08-11
Abstract: 1330073 Fluid regulation J C ECKARDT AG 11 Aug 1971 [28 Aug 1970] 37730/71 Heading G3H In a square wave generator, Fig. 3 (not shown), the differential pressure amplifier 1 comprises two spring bellows separated by a base plate 2, the bellows and plate defining opposed chambers 3 and 4. Chamber 3 is fed from the amplifier output A via an adjustable resistor 8 and a time delay element Tf; chamber 4 is loaded by a constant pressure source Ko connected to a pressure divider 10, 11, the other side of which divider is connected to the amplifier output A. Additionally this amplifier includes an air supply source Pz leading to a choke valve 6 which connects to a nozzle 5 and to an amplifier 7, this nozzle being controllable by the plate 2 and amplifier 7 being arranged to provide the output A of the differential amplifier 1. With the pressure differential across chambers 4 and 3 being such that nozzle 5 is closed, the generator output is the amplifier output A as derived from air source Pz. Upon the differential being reduced consequent to the elapse of a time factor, the plate 2 lifts off of nozzle 5 and so the generator output becomes equal to the atmospheric input of nozzle 5. A modified form of differential pressure amplifier is depicted in Fig.2 (not shown), such amplifier forming the subject matter of Specification 1277148.

Title: Improvements in or relating to meth ods and compositions for permanent waving of hair
Filed: 1954-12-31
Abstract: A method of fixing waves in hair, after the disulphide linkages present in the hair keratin have been split to mercaptan groups by treatment with solutions of sulphites, mercaptans and the like, comprises treating the hair with a solution or emulsion containing a compound having at least one non-aromatic carbon-carbon unsaturation, which reacts additively with the split disulphide linkages.  The unsaturated linkage may be olefinic or acetylenic.  The unsaturated compounds are preferably used in water in concentrations of 0.5-7.5 per cent or more, but generally 2-4 per cent, and contain preferably at least one hydrophilic group so as to ensure solubility at these concentrations.  This group may be a carbonyl group (as in carboxylic acids and their salts, ketones, aldehydes, quinones, lactones, amides, imides and esters), or a nitrile, hydroxyl, or sulphonic acid group.  It is prefered, however, to use those compounds containing an unsaturated linkage conjugated with a carbonyl group.  Maleic acid, fumaric acid, crotonaldehyde, methylene bisacrylamide, and 1, 2-naphthoquinone-4-sulphonic acid are the preferred compounds, but a list of other suitable compounds is given.  If desired, the solution may also contain those oxidizing agents conventionally used for fixing waves, such as peroxides, perborates, bromates or hypochlorites, in concentrations of about 0.1-1.0 per cent.

A development of the variable-frequency/ variable-repetition rate, pulse radar of Specification 994,757 is described wherein, to overcome the fault of said prior art that interference of the transmitted frequency is received and displayed, said interference is integrated 16 to trigger a monostable circuit 17 when a threshold is reached, whereby an AND gate 18 allows into a memory 19 the output of the local oscillator frequency control means 11 such that the frequency of the interference is on record and may be used to detect, by comparator circuit 20 fed from means 11, when the transmission frequency is again at the interference frequency to then produce a signal inhibiting, by means of gate 21, the display of the interference on PPI display 15. The comparator circuit 20 may comprise two balanced transistors T1, T2 having a common emitter resistance and the signals to be compared applied to respective bases. Equal collector diodes are connected to a switching pulse-forming device. Assuming the voltage at the base of T1 is highest, this transistor will conduct and, due to the common emitter resistance, transistor T2 will cut off. The collector of T2 will be at positive bias potential and this will be applied via a diode device 22. Only when the two applied voltages are equal, and each transistor conducts simultaneously, does the potential applied to device 22 fall below that of the positive bias, producing the switching pulse.

Abstract: 1,163,101. Digital control systems. SAAB AB. 30 Aug., 1966 [6 Sept., 1965], No. 38564/66. Heading G4H. In a control system, e.g. for a machine tool, pulses generated by a unit 7 (Fig. 2) as the work table moves, are compared in a counter 3 with the required position of the table, pulses received after the driving motor has received a stop signal being counted and if a predetermined number of such pulses are received an alarm signal is given. The motor 5 is controlled during normal working conditions by a voltage from a voltage divider 13. When the table nears its required position a contact 16 is moved under the control of the counter 3 so that the motor 5 is driven more slowly at a speed determined by the setting of a uniselector 15 until a further contact 17 is operated when the required position of the table has been reached. The uniselector 15 is controlled in accordance with the position of a uniselector 11, the setting of which determines the amount by which the table may overshoot the required position before an alarm signal is generated by the member 12. In a modification, the motor 5 is driven at a constant speed, but the speed at which the table moves is determined by a gear-box having magnetic clutches controlled by uniselector. In a further embodiment (Fig. 4), the counter 3 has a plurality of outputs 25 sequentially energized as the table nears its required position, one of the outputs controlling a contact 27 via selection means 26 so that the table is driven at a slower speed.
