Title: Improvements in and relating to devices for regulating the action of brakes
IPC: B60T8/24
Filed: 1939-02-27
Abstract: 525,721. Vehicle brakes. BRIAND, H. Feb. 27, 1939, No. 6407. Convention date, March 2, 1938. Addition to 460,476 [Class 103 (i)] The brake oi the parent Specification is modified by the provision of a plurality of operating members one for each brake and a plurality of cams, one between each operating member and the central control member and operated by the vehicle steering mechanism. Each of the four wheel brakes of a vehicle is operated by one of a series of parallel hydraulic cylinders such as 41 which are operated by levers such as 44a operated by the brake pedal with the intermediary of cams in the form of wedge members such as 53a adapted to be moved by eccentrics such as 51a adapted to be turned by a connection to the steering mechanism so as to withdraw the wedges or thrust them further between the brake operating means. The eccentrics associated with the two rear wheel brakes are larger than those associated with the front wheel brakes. The diameters of the eccentrics passing through the axis of the spindle are all at equal angles to the vertical when the steering is central, but the inclination of the diameters corresponding to the right hand brakes is opposite to that of the left hand brakes so that there is a greater braking action with the brakes on the inner side of a curve.

Title: Improvements in or relating to a process for preparing ª:ª-dichlorpropionates
IPC: C07C69/653
Filed: 1953-03-10
Abstract: a  : b -Dichloropropionic esters of monohydric alcohols are prepared by reacting chlorine with acrylic acid esters of monohydric alcohols in the presence of a minor proportion of an N-substituted aliphatic carboxylic amide.  The amount of amide present must be at least 1/2 per cent by weight of the acrylic ester but need not exceed 10 per cent.  Preferred amides have the general formula <FORM:0730328/IV (b)/1> where R is hydrogen or an aliphatic hydrocarbon group of not more than 8 carbon atoms and R1 and R11 are hydrogen or hydrocarbon groups having not more than 12 carbon atoms, at least one of the terms R1 and R11 representing such a group, or R1 and R11 may together form a saturated divalent chain forming a heterocycle with the nitrogen atom.  Numerous of such amides are mentioned including N-methyl formamide, morpholine formamide, aceto-piperidide, N-butyl acetamide, N-methyl acrylamide, N : N-diethylhexamide, N - methyl - N - phenyl acetamide, N : N-dimethadipamide and N : N : N1 : N1-tetramethylsuccinamide.  The chlorination is generally effected at about 20-50 DEG  C.; inert solvents such as chlorinated solvents or alcohols, e.g. glycerol and ethylene glycol may be present.  The acrylate esters for the chlorination include alkyl, alkenyl, aralkyl, cycloalkyl and terpenyl acrylates and those containing inert substituents in the alcohol residue such as methoxyethyl, ethoxyethyl, dimethylaminoethyl, tetrahydrofurfuryl and ethylthioethyl groups and numerous compounds are mentioned. Examples describe the chlorination to the corresponding a  : b  - dichloropropionates of methyl-, ethyl-, tert. - butyl-, cyclohexyl-, benzyl-, n-octyl-, dodecyl- and octadecylacrylates. In examples 1 and 12, the resulting methyl- and tert.-butyl-a  : b -dichloropropionates are treated with aqueous alkali to form the esters of a -chloroacrylic acid.  Comparative tests are given showing the lower yields obtained when methanol or formamide replaces the N-substituted amide in the reaction.

Title: Improvements in or relating to the preparation of concentrated edible products from invertebrates
IPC: A23J3/34
Filed: 1941-05-28
Abstract: 549,613. Vitamins. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). May 28, 1941, No. 6861. [Class 2 (iii)] [Also in Group VI] Concentrated edible products are obtained from material containing proteolytic ferments and originating in, or obtained from, invertebrates, such as mussels, oysters, shrimps &c. by treatment of the finely divided material with acid so that the liquid of the paste has a pH value between 1 and 4, digesting under the influence of the ferments by heating at 37‹-40‹C. until a dialysable solution is produced, sterilizing as by heating to 100‹C. for a short period, removing the undigested residue as by filtering, centrifuging &c. and-evaporating the solution to dryness, preferably at a reduced pressure and below 50‹C. A vacuum or spray drier may be employed. The solution may be subjected to dialysis, and the pH value raised to between 6 and 8, before evaporation. Shrimps may be prepared for treatment by pressing the flesh out of the shell by means of a pair of inclined rubber, or resiliently-mounted metal, rollers, or may be comminuted with the shells and calcium chloride removed by dialysis through a collodion membrane. Crustaceans may be crushed by rough tools or ground, e.g. in a hammer mill, and the flesh separated from the crushed or ground shells by methods based upon the different specific weights. Fatty matter may be extracted before, during or after digestion for the preparation of provitamin D. In the first case, extraction may be effected by a solvent, e.g. ethyl acetate, which is not deleterious to the ferments and is partly miscible with water. The flesh paste may be dried by atomisation before extraction or may be separated from liquid as by centrifuging, dried, subjected to fat extraction and mixed again with liquid. Alternatively, water and fat may be removed from the comminuted flesh by different solvents or both by means of acetone. In the second case, petroleum ether vapour may be blown upwardly into the liquid and drawn off at the top. The proportion of albumen digested decreases, and the proportion of provitamin decomposed increases, as the pH value during digestion decreases. Specifications 378,399 and 471,994 are referred to.
Patent GB-820160-A (GB)
Title: Hydrocarbon separation process employing molecular sieve adsorbents
IPC: C07C7/13
Filed: 1958-03-04
Abstract: In the separation of hydrocarbons using a molecular sieve adsorbent the hydrocarbon mixture is contacted with the sieve for a period of time less than 4 minutes and sufficient only to attain 75-90 per cent of maximum adsorption of the selectively adsorbed hydrocarbons and the adsorbed hydrocarbons are desorbed, preferably immediately.  The separation of normal paraffins from other hydrocarbons may be effected with 4-6   sieves at 200-400 DEG  F. and a pressure close to the liquefaction pressure.  Desorption is preferably effected under conditions whereby the content of adsorbed hydrocarbon is reduced e.g. by raising the temperature and/or reducing the pressure preferably below 50 mm. Hg., with or without the aid of a purge gas. The sieves may be employed in fixed beds or in a moving or fluidized bed.  The feed is preferably first dried and purified by passage over a 4   sieve or silica gel.  In one embodiment using fixed beds, three zones are employed, one being desorbed while the feed passes through the other two in series, the first of which is put next on to desorption when 75% to 90% adsorption is attained, i.e. when the effluent from this first zone contains 75-90% of the normal content of the adsorbed hydrocarbons, and the feed being then passed through the second of these zones and then through the one previously being desorbed.  When using fixed beds desorption and adsorption are performed at the same temperature to avoid time spent in heating and cooling.  Moving or fluidized bed operations are preferred since in such cases adsorption and desorption performed in separate vessels need not be effected isothermally. Adsorption may be effected in concurrent or countercurrent flow. Desorption may be effected in such cases at 600-800 DEG  F. maintained by heating coils, by a moving bed of heated shot particles or by recycling a stream of hot desorbate. Flow rates of feed and sieve to the adsorption zone to obtain 75-90% adsorption are determined in a pilot run.  A stream of sieves may also be taken from the desorption zone to a regenerator, regeneration being accomplished by burning or steam stripping.

Title: Improvements in or relating to oscilloscope operating circuits
Inventor: BATES THOMAS
IPC: H03K5/08
Filed: 1968-02-13
Abstract: 1,246,472. Transistor sawtooth generators. MARCONI INSTRUMENTS Ltd. 2 Dec., 1968 [13 Feb., 1968]. No. 6911/68. Heading H3T. A time-base is triggered by an electronic switch such as a bi-stable (8, Fig. 2, not shown) when the switch senses the attainment of a predetermined magnitude ("ON", Fig. 6, not shown), by a signal derived (at 7) from an input signal to be displayed on an oscilloscope, the derived signal having been made symmetrical about a chosen reference level (Earth, Fig. 6) irrespective of the mean value of the input signal. The switch is reset by a magnitude of the derived signal equal and opposite to the said predetermined amplitude ("OFF", Fig. 6) to prepare it for the next sweep. In one circuit for changing the level of the input signal, the latter is applied (1, 1, Fig. 5, not shown) to a peak-topeak detector circuit comprising a capacitor 11 and a diode 9 in series, from the junction of which a second diode (10), oppositely poled with respect to the input signal, is connected through a capacitor (12) and across the first diode (9); across the second capacitor (12) is connected a pair of equal series resistors from whose junction a voltage representing half the peak-to-peak amplitude is obtained. This is connected to a capacitor (17) to define a reference level, and the input signal (at 1, 1) is applied through a further capacitor (15) to the output terminal (20) which is connected also to the anode of another diode (16) whose cathode is  connected to the reference level capacitor (17); the diode (16) has a resistor (18) across it. The output signal (at 20) is thus negative-going from a reference level of half its peak-to-peak value. and is thus symmetrical about Earth (Fig. 6, not shown). In a second embodiment, Fig. 7, a long-tailed pair 23, 24 receives the input signal from an emitter follower 22, the output being taken from a tunnel diode 21 connected to the collector of transistor 21 and constituting the bi-stable switch which triggers the time base. The transistor 24 has a collector resistor 25 and a pair of peak detector diodes 26, 27 oppositely connected to equal series resistors 28, 29 with capacitors across them. The junction of these resistors is held at a reference level such as +15 v., and the voltage appearing at the junction of a further pair of equal resistors 31, 32 varies from this reference level if the rectified voltages of diodes 26 27 differ. The varying voltage is applied to an emitter follower 33 from whose emitter load a reference voltage for the base of the transistor 24 is taken. This reference voltage is thus varied as the mean level of the input signal varies, and the tunnel diode operating conditions are maintained unchanged so that it triggers from one state to the other at predetermined levels of the input signal as determined by the reference level of 15 v., which is the mean value of the two switching levels required.

Title: An arrangement for shooting from shipborne gun carriages
IPC: F41G5/22
Filed: 1959-02-27
Abstract: 898,087. Sights. PHILIPS GLOEILAMPENFABRIEKEN N.V. Feb. 27, 1959 [March 4, 1958], No. 6912/59. Class 92. Relates to a sighting arrangement for correct aiming independent of the rolling and pitching of a ship when firing off projectiles, e.g. those with low delivery speeds such as depth charges, from shipborne gun carriages. According to the invention in addition to a device which supplies the gun laying means with deck-tilt angles in relation to a horizontally-stabilized co-ordinate system and which actuates the laying means so as to eliminate the influence of the deck-tilt, a speed indicator is provided to indicate the speed components of the gun carriage in the directions of the three co-ordinate axes, these components actuating the laying means to obtain a compensation for the speed increase or decrease of the projectile at firing caused by the motions of the gun carriage in vertical and lateral directions. An altimeter is also provided which actuates the laying means to compensate for the influence of the change of height of the gun carriage during rolling and pitching on the impact point or range of th projectile. Three accelerometers (not shown) are arranged in direct connection with the gun carriage and generate voltage components a N , a O , a Z  proportional to the accelerations along the three co-ordinate axes to which the gun carriage is subjected during rolling and pitching. These voltage components are fed to integrator devices I N , I O , I Z1  which give output voltages V N  V O  V Z  proportional to the corresponding speed components. These are fed to the laying means. A voltage H proportional to the variations of the height level of the gun carriage is obtained by the integration of the component V Z  in the integration device I Z2  and this value H is also fed to the laying means. The average values of the voltage components V N , V O , and H must coincide with the corresponding speed components V eN , V which are valid for the ship and with the height level H of the gun carriage above sea level when rolling and pitching is zero. Voltage comparing members S 1 , S 2 , S 3  are therefore provided which compare the voltages V N , V O , and H with the voltages V eN , V eO  and H and which at the occurrence of differences generate voltages which are supplied to the integrator devices I N , I O , I Z1  so that the differences tend to be counterbalanced.
