IPC: G05D3/14
Filed: 1948-01-06
Abstract: 671,355. Electric control systems. ROLLS-ROYCE, Ltd. Feb. 4, 1949. [Jan. 6, 1948] No. 441/48. Class 40 (i). [Also in Group XXXV] An electrically operated control system comprises a displacement sensitive means initiating the operation of an electric motor to displace an actuator element, which unbalances two normallv balanced electromagnetic fields to produce movement of an armature driving a follower element operative to rebalance the .electromagnetic fields, and to drive means for applying a counter displacement to the initiating displacement sensitive means whereby the operation of the electric motor is terminated and the movement of a controlled mechanism driven thereby is limited to an extent determined by the initial displacement. In an application to the positional control of aircraft radiator flaps by the coolant temperature, a thermometric bulb 42 immersed in the coolant contains an expansible liquid connected to a bellows 44 whose expansion or contraction with temperature is transmitted through a pushrod 45 to a spring-loaded lever 46, which rocks about an abutment 50 bearing on a shoulder 51 of the pushrod, and is pivoted at 47 to a lever 48 having a fixed pivot 49. Displacement of the lever 46 engages the contact 56 with either of the contacts 57a or 57b to energize the relay winding 58a or 58b to energize one or other of the field windings of the reversible D.C. actuator motor 30, which opens or closes the flaps 20 in accordance with temperature variations from normal. The flap displacement is operatively coupled. to differentially vary the master resistances 24, 25 in series with the fields 26a, 26b of a reversible D.C. motor 26 so that the motor runs in accordance with the field unbalance to vary the follow-up resistances until the fields are rebalanced, and drive the cam 41 through reduction. gearing to rock the lever 48 about its pivot 49 and thus rock the lever 46 about its abutment 50 to counteract the displacement of the contact 56 due to the expansion of the thermometric liquid, and stop the flap actuating motor at the required point. The field circuits of motor 30 may include flap limit switches 61, and the motor 26 is replaceable by a polarised relay controlling a separate reversible motor driving the cam and follow-up resistances. The provisional specification refers to systems wherein the initial displacement for radiator flap control is produced by a hand lever, and wherein the thermometric device differentially varies a pair of master resistances to unbalance the fields of a first motor, which deflects a moving contact between two fixed contacts to control the direction of rotation of a second motor to displace the radiator flaps, and thus vary the follow-up resistances to rebalance the fields of the first motor, and arrest the motor movement.

IPC: A61K8/00
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To obtain a hair tonic cosmetic stable over time by its pH adjustment. SOLUTION: This hair tonic cosmetic is obtained by removing pilocarpine from the extract from the leaves of pilocarpus, a kind of rutaceous plant (e.g. pilocarpus jaborandi, pilocarpus microphyllus), and adjusting the pH level of the resultant extract to >=2 but <7. The amount of the active ingredient of this cosmetic to be formulated is pref. 0.005-10wt.% (in terms of dry weight) based on the whole amount of the cosmetic. The pH adjuster to be used is e.g. an alkaline substance such as an alkali (alkaline earth) metal hydroxide. The extraction is preferably carried out at 10-100 deg.C for one hour to 10 days by use of 5-100 pts.wt. of a solvent (e.g. water, ethanol) per pt.wt. of the dry leaves.  Besides, it is preferable that this cosmetic be formulated with a germicide such as benzoic or salicylic acid because of possible decline in its antimicrobial potency depending on its pH level.
