Patent GB-840823-A (GB)
Abstract: 840,823. Calculating machines. SIEMAG FEINMECHANISCHE WERKE G.m.b.H. May 17, 1957 [May 22, 1956], No. 15779/57. Addition to 799,065. Class 106 (1). In the arrangement of the parent Specification in which differentially-movable actuating racks or the like of a calculating-machine position sliding contacts for the electrical transmission of a number set up, digit-by-digit, to a typewriter, and in which the sliding contacts co-operate with a detent which retains them in set positions while the actuating racks are restored, the detent is controlled by cam means during the calculating machine, cycle so as to become effective some time after the racks have reached their differential positions. In this way errors due to temporary over-running of the sliding contacts are avoided. The rack 1 advances a rod 2 carrying the contacts 8, 9 which respectively engage digit contact strips 5 and a corresponding denominational contact-rod 7. The rod 2 also carries a pawl 10 and all of these pawls co-operate with a detent plate 12 apertured to receive the pawls in accordance with their digital positions and adjustably secured to an arm 13. Early in the advance of the racks 1, a lever 19 is cammed to the dottedline position and its ear 22 rocks a lever 25 which depresses the arm 13 so that the detent plate 12 is ineffective. Just before the racks 1 are returned, the lever 19 is restored and a spring 27 restores the arm 13 so that the detent 12 engages the pawls 10 and so maintains the rods 2 and the associated contacts in their differential positions.
Patent GB-2139932-A (GB)
Title: Metal casting
Inventor: WARD RICHARD
IPC: B22D15/04
Filed: 1984-05-04
Abstract: Castings are produced by sandwiching a central mould part (10) between two outer mould parts (36, 38) at a pouring station (35). The central mould part (10) is then transferred from between the outer mould parts (36, 38) knocked out, cooled, dried and subsequently re-located between the outer mould parts in a vacant, relatively cool, and dry condition for the production of a further casting. In one embodiment a plurality of central mould parts are transferred sequentially from the outer mould parts to a knock-out station (45), a quenching station (50) and a drying station (70) before being returned to the central mould parts. Other features of disclosure are: (a) a central mould part (Figure 4, not shown) shaped such as to reduce welding on where the molten metal first strikes the mould bottom; and with a specially-shaped filling opening to reduce wear and welding on; (b) hot working equipment placed near the knock-out station to utilise residual heat of the castings; (c) forming a hole in a casting during its shaping in the mould; (d) making two mirror-image artefacts by shearing into halves a single casting formed in an appropriately-shaped mould. <IMAGE>

Title: Method for the production of a metal patterning mask
Inventor: MARTIN DR BRIAN
IPC: G03F7/30
Filed: 1984-10-08
Abstract: A negative photoresist is developed by a multiple puddle method, the concentration of the aqueous alkali developer being of a lower concentration than the minimum required to reduce the adhesion of the resist to the underlying substrate. The steps of: forming a puddle of developer on the resist, allowing a period for development to take place and washing the developer away, are repeated until the upper part at the photoresist overhangs the lower part at the edges exposed to the developer. The resist/substrate is then coated with metal (e.g. Al) and the unwanted metal overlaying the remaining resist material may be lifted off by immersion in a fuming nitric acid solvent.

Title: A humidity measurement or control instrument
Inventor: DADACHANJI FALI MINOCHER
IPC: G01N27/12
Filed: 1985-03-25
Abstract: An instrument for use in humidity measurement and control, comprises two identical electrically resistive humidity sensors (10A, 10B), the sensors (10A, 10B) being disposed in physical proximity to one another, but with one of the sensors (10B) being kept in a sealed housing A at a predetermined set humidity and the other (10A) being exposed to the environment of which the humidity is to be measured. The humidity in housing A is kept at a predetermined set humidity by mounting within housing A a piece B of absorbent material impregnated with a saturated solution of salt or salts, body B being separated from the sensor 100 by a vapour phase permeable membrane C. A signal is derived from the sensors 10A, 10B, corresponding to the difference between the measured humidity and the set humidity, whereby the measured humidity may be determined as the algebraic sum of the predetermined set humidity and the difference. <IMAGE>

Title: Process for the isolation of fermentation products
Inventor: HINCHLIFFE EDWARD
IPC: C12N15/00
Filed: 1986-04-22
Abstract: The invention provides a process for the production of ethanol and a protein or peptide which is heterologous to yeast which comprises fermenting an aqueous carbohydrate-containing medium with an industrial yeast strain which has been genetically modified to be capable of expressing a heterologous protein or peptide, under conditions such that the yeast multiplies but no expression of the said heterologous protein or peptide takes place, recovering the ethanol so-formed, inducing expression of the said protein or peptide by the yeast, and obtaining the said heterologous protein or peptide therefrom. The process may be applied to the industrial production of alcoholic beverages such as beer or distilled alcohol. The yeast inevitably obtained as a by-product in the process has improved value because it provides a source of the heterologous protein or peptide. Heterologous protein and peptides which may be produced by the new process include enzymes such as beta-lactamase, beta-glucanase and beta-galactosidase and proteins of therapeutic value such as human serum albumin.

Filed: 1988-03-09
Abstract: A device for separating two orthogonally polarised modes in a waveguide comprises two openings 5, 6 in the wall of the waveguide 1 spaced apart along the length of the waveguide, first means such as a row of rods 2, between the openings to transmit one plane of polarisation E2 and to reflect the orthogonal plane E1 into a transverse waveguide 7, and second means beyond the openings, which may consist of a conductor 3 at 45 degrees and a short circuit 4, for retro- reflecting the transmitted plane of polarisation E2 and for rotating its plane of polarisation through 90 degrees into the plane E1, in order that it may be deflected into transverse waveguide 8. The device may be used as the feed of a reflector antenna, one of the branches 7, 8 being used for transmitted radiation and the other for received radiation, and the device presents minimum blockage of the reflector, because both branches 7, 8 present their narrower dimension to the incoming radiation. <IMAGE>
