Title: Stabilizing sera
IPC: C07K16/00
Filed: 1959-06-08
Abstract: Stable non-toxic derivatives of sera obtained from animals which have been immunised by injecting into them a cell suspension or cell extract of human embryonic tissues, e.g. in accordance with the processes claimed in Specification 763,752, are obtained by reacting the sera as such or in aqueous solution with a beta lactone of formula  <FORM:0872122/VI/1> wherein R1 and R2 are hydrogen or alkyl, especially C1 to C6 alkyl and in particular betapropiolactone, or an alkylene oxide such as ethylene oxide and propylene oxide. The excess reactant is removed by treatment with a water-insoluble organic solvent such as benzene.  The reaction takes place at - 10 DEG  C. to 25 DEG  C.  The product is lyophilized and dissolved in normal saline to produce a solution for injection.  The serum derivatives may also be incorporated into cosmetics, especially creams and lotions.

Filed: 1971-06-08
Abstract: 1356660 Positioning apparatus INFORMATION STORAGE SYSTEMS Inc 8 June 1971 [8 June 1970] 19510/71 Heading G4H A servo mechanism for positioning, for example, the read write heads of a disc data store, intermittently switches the servo drive between a first state with a deadband in the transmission drive signal, and a second state without the deadband. A counter 19 receives from registers 16, 17 the difference between the present and desired positions of read/write heads 10 and feeds a D/A converter 20 to give an error signal for driving linear motor 14. The error signal is modified in summer 21 according to the speed and direction of movement of the heads, and amplified in amplifier 22, which is switchable between a deadband and a non-deadband condition. Oscillator 30 supplies a signal to amplifier 22 to periodically switch it between the two states so that the head 10 is positioned more quickly than it would be under deadband conditions while hunting and oscillation are still avoided.

Title: Improvements in or relating to the production of formaldehyde
IPC: C07C45/33
Filed: 1949-07-29
Abstract: Formaldehyde is produced by the oxidation of methane using oxides of nitrogen as catalyst by passing methane mixed with air and/or oxygen and with the catalyst through a heated reaction zone maintained at a pressure below atmospheric, and then separating formaldehyde from the gases leaving the reaction zone.  The pressure may be between 0.05 and 0.9 atmospheres.  A 38-40 per cent solution of formaldehyde in water may be obtained by scrubbing the gases leaving the reaction zone with water either at the reaction pressure or at atmospheric pressure. Paraformaldehyde can be obtained directly by chilling the product gases to, for example, 0 DEG C.  In the examples mixtures of methane, oxygen and oxides of nitrogen are passed into a heated reaction zone at various temperatures and at various pressures below atmospheric pressure to give formaldehyde.
