Title: Improvements in and relating to the processes for the enzymatic degreasing of bones
IPC: C11B1/02
Filed: 1968-10-18
Abstract: 1,242,105. Enzymatic degreasing of bones. SOC. D'ETUDES ET D'APPLICATIONS BIOCHIMIQUES, and COMPAGNIE DES GELATINES FRANCAISES. 18 Oct., 1968 [20 Oct., 1967], No. 49616/68. Heading C5D. A process for the enzymatic degreasing of bones containing 15 to about 35% by weight of lipoids comprises subjecting the bones to the action of a lipase in the presence of a soluble calcium salt at a pH of 5-8 in aqueous solution and at a temperature of 20-45 C. The lipases may be of animal, vegetable or microbial origin a preferred lipase being R.a.D and the process is preferably carried out for a period of 3-20 hours. The bones may be subjected to a pretreatment with hot water to remove part of the lipoids adhering to the bones whilst it is preferable to use bones in a finely divided state. The preferred calcium salt is calcium chloride and this, as also is the lipase, suitably used in an amount between 0À2 and 10 gms. per kilo of bones. During the process the reaction media may be gently stirred. After treatment the enzymatic solution is separated from the bones and the treated bones washed with water suitably at a pH of 7-8À5. The lipasic solution may be recycled and the treatment repeated.

Title: Preparation of antibiotics
IPC: B01J31/00
Filed: 1971-10-27
Abstract: 1355578 Derivatives of antibiotics SF-837 and SF-837A, MEIJI SEIKA KAISHA Ltd 27 Oct 1971 [27 Oct 1970] 50014/71 Heading C2A Novel isomers of antibiotics SF-837 and SF-837A 2  are produced by subjecting the said antibiotics to treatment with aqueous acid at a pH from 1 to 5 for a sufficient time to cause allylic rearrangement thereof and recovering the rearrangement product from the reaction mixture. The isomers are believed to have the general formula wherein for the isomer of SF-837, R 2  is -COCH 2 CH 3  and for that of SF-837 A 2 , R 2  is -COCH 2 CH 2 CH 3 , R 1  being -COCH 2 CH 3  in each case. The preparative process is effected by dissolving the parent antibiotic in aqueous acid which may contain up to about 50% of watermiscible solvent (e.g. ethanol, acetone, dioxan or tetrahydrofuran), preferably at a pH from 2 to 3À5. The allylic rearrangement takes place over a period dependent upon the pH and temperature, suitable temperatures being between 10 and 80 C., preferably 15 to 50 C., a typical rearrangement process being conducted at pH 3À0 and 50 C. for 4 hours. The products consist of the desired isomer and unchanged parent antibiotic, e.g. in a ratio of 4 : 6 under favourable conditions, together with a variable amount of decomposition (hydrolysis) products. The acids used include hydrochloric, phosphoric, hydroiodic, hydrobromic, sulphuric, acetic, monochloro-, trichloro- and trifluoro-acetic, propionic, tartaric, oxalic, malonic, maleic, citric, p-toluenesulphonic and methane-sulphonic acids. The desired isomer may be recovered by bringing the reaction mixture to neutral or alkaline pH, extracting with a waterimmiscible solvent (e.g. ethyl acetate, chloroform or ether), evaporating the extract to dryness and washing the dry product with a little benzene to remove the parent antibiotics. The residue of isomer may then be recrystallized, e.g. from acetone. The novel isomers have activity against Grampositive bacteria and may be used in pharmaceutical compositions with a suitable carrier for topical, parenteral or oral administration.

Abstract: 1488439 Liquid-ring vacuum pumps GENERAL SIGNAL CORP 11 Dec 1975 [27 Dec 1974] 50807/75 Heading F1C A single-stage or multi-stage liquid-ring vacuum pump 12 evacuates gas from a chamber 11 and delivers it, together with entrained liquid from the liquid-ring, to a separator 30, from which the separated gas is withdrawn by an auxiliary vacuum means such as a vacuum pump 66, the separated liquid being returned to the liquid-ring pump via, it may be, a pump 56. A heat exchanger 52 may be provided upstream or downstream of the pump 56 for cooling the returned liquid. A check-valve 59 may be provided to bypass the pump 56 when the liquid flow exceeds the capacity of the pump. The liquid used may be one having a low vapour pressure, such as polyglycol, phosphate esters, synthetic esters, oil or kerosene. This fact, together with the fact that the vacuum exerted by the vacuum pump 66 removes dissolved air from the liquid and therefore reduces the amount of air which can come out of solution from the liquidring within the liquid-ring pump, allows the liquidring pump to operate down to a low pressure of À02 Torr. A connection to atmosphere via a checkvalve 74 allows the separated gas to pass to atmosphere if a shut-off valve 68 is closed or if, as when the liquid-ring pump 12 commences operation, gas is removed from the chamber 11 at a greater rate than can be handled by the auxiliary vacuum pump 66.

Abstract: 1481817 Temperature responsive actuators GOULD Inc 27 Nov 1974 [27 Nov 1973]  51413/74 Heading G1D [Also in Division H1] A de-energizing system for a thermal actuator 10 of the type having a variable volume chamber and a piston movably positioned in the chamber, the piston being moved by pressure exerted by a thermally expansible material in the chamber, comprises as support, means for movably supporting an actuator 10 relative to the support, means for selectively coupling an actuator 10 to an energy  source, and means responsive to an overload condition of an actuator 10 when supported to de-energize the same, said means being responsive to movement of actuator 10 relative to the support upon overloading and also being operatively coupled to said selective coupling means. As described, the actuator 10 is slidably mounted within a casing 30, a spring 50 biasing the actuator, in normal operation, against end stop 53. If an externally applied load 33 or the output force of the actuator 10 exceeds the pre-load force of the spring 50, the actuator 10 moves relative to the casing 30, a pin 41 mounted on the actuator body 11 breaking the connection between contacts 42, 43 and thereby breaking the heating circuit to the actuator heater. The resultant cooling of the actuator causes retraction of the piston 26 to allow spring 50 to force the actuator casing 11 against end stop 53, the heating circuit then closing. Normal operation will then resume unless the condition causing overload has not been removed in which case the circuit will be broken once more, the cycle continuing until the overload condition is rectified. The actuator 10 is of the piston cylinder type. In a prior art actuator described, the thermally expansible material within the variable volume chamber may be an azeotropic mixture of at least two liquids having different melting points, a metal hydride, or other expandable material e.g. an oil, wax or alcohol.

Title: Timing circuit apparatus

Filed: 1966-04-16
Abstract: 1,140,357. Timing circuits. E. W. BLISS CO. 16 April, 1966 [16 April, 1965], No. 52047/65. Heading H3T. [Also in Division H2] In a timing circuit of the type wherein an electronic device discharges a capacitor when the voltage on the latter has risen to a predetermined value, the bias on the control electrode of the device consists of a cyclically varying direct voltage so that the moment of firing depends on the phase and frequency of the cyclic component. In the circuit of Fig. 1, initially S1 is closed with S2 open, so that relay CR1 is not energized; contacts CR1-1 and CR1-2 are open while CR1-3 is closed. The timing capacitor 14 is then shorted by diode 40 and resistor 38 and the circuit does not operate. To start the cycle S2 is closed to energize CR1 and open contacts CR1-3 allowing capacitor 14 to charge from the A.C. supply rectified by diodes 26, 28, 30, 32. At the same time contacts CR1-1 close and energize the load 42 through normally closed contacts CR2-1. The unijunction transistor has its base B2 supplied from the rectified A.C. through diode 34 and capacitor 36, the latter being of low value so that a ripple voltage of twice the supply frequency is present, preferably to the extent of 5% or more of the steady voltage. When the voltage on capacitor 14 reaches a predetermined value, the unijunction will conduct and raise the gate potential of SCR 44 to fire it. Relay CR2-C is then energized to open contacts CR2-1 and disconnect the load 42 from the supply. Switch S2 is then opened (by an operator or by an electronically responsive device) to restore the initial conditions ready for the next cycle, contacts CR1-2 opening to stop current through the SCR. The presence of the ripple voltage on base B2 of the unijunction improves the accuracy of timing by tying the point of firing to a particular point in the cycle of ripple frequency and making it less dependent on the magnitude of the supply voltage. The accuracy can be further improved by omitting capacitor 35 (and optionally diode 17) so that a ripple is also present on capacitor 14 charging voltage. This will lead the ripple voltage on base B2 so that at the point of firing the voltages on base and emitter of the unijunction will be approaching one another. The accuracy can also be improved by increasing the frequency of the supply voltage. Other timing circuits A2 &c. with different loads can be supplied from the same ripple source. The unijunction may be replaced by a thyratron or neon tube. The circuit may be used for controlling the timing of a bottlefilling mechanism or of a stitching machine.
