Abstract: 1427468 Vehicle safety devices MOTOROLA Inc 25 Jan 1974 [15 Feb 1973] 03678/74 Heading B7H [Also in Divisions H3-H5] In a protective arrangement for a car, if the driver is first seated and then fastens the safety belt a relay 536 is operated to start the car, but if the seat-belt is fastened first a warning buzzer 537 is sounded and the car will not start. An input is applied to terminal 503 to indicate if the driver has his weight on the seat, and terminal 529 receives an input indicative whether the seat belt is fastened; in both cases the signal comprises earthing of the corresponding terminal. If the order is correct, circuit 505 causes a "1" to be stored in flip-flop 520, but if incorrect a "0" is stored instead: the state of the flip-flop is detected at the output of emitter-followers 522 by circuit 530. In the case of a correct sequence, output transistor 532 is turned on to operate starting relay 536, but an incorrect sequence turns on transistor 534 instead, to operate buzzer 537. Transistors 532, 534 are protected against transient overvoltages on supply line 538 by means of a circuit comprising Zener diode 545, resistors 546, 547, 548 and transistors 549, 550 (see Divisions H3-H5).

Title: Improvements relating to fans
IPC: F24H3/04
Filed: 1959-11-16
Abstract: 943,767. Transverse-flow and centrifugal fans. FIRTH CLEVELAND Ltd. Nov. 16, 1959 [Nov. 17, 1958; April 15, 1959; April 27, 1959], No. 4340/63. Divided out of 942,537. Heading F1C. A fan comprises a cylindrical bladed rotor which defines an interior space and has an opening at one end, the arrangement being such that on rotation of the rotor air flows into the interior space both through the path of the rotating blades and also through the opening, and flows from the interior space out through the path of the rotating blades, an end portion of the rotor adjacent the opening operating as a centrifugal fan and a portion of the rotor not adjacent the opening operating as a transverseflow fan. In the fan shown, two impellers 11, 12 are carried by the shaft of an electric motor 9 located between them. Each impeller is closed at its end adjacent the motor and open at the other end. Air is drawn into the open end of each impeller through an opening 4A or 5A in the side of the casing 1 and is discharged by the impeller into discharge duct 19, whereby the impeller acts as a centrifugal impeller at its end remote from the motor 9. Air also enters the casing 1 through slots 21a and flows above a partition 16 towards the impellers. It then flows twice through the blading of each impeller, first radially inwards to the centre of the impeller and then radially outwards into the discharge duct 19, whereby each impeller acts as a transverse-flow impeller over the region not adjacent the open end of the impeller. A guide wall 22 extends from the partition 16 to form with each impeller a gap 23 which diminishes in the direction of rotation. An electric heater 28 extends across the discharge duct 19. The air discharged from the fan induces a secondary flow through a nozzle 31. The casing 1 is formed from two interlocking unitary moulded parts 6, 7. Specifications 876,611 and 943,768 are referred to.

Abstract: 635,391. Surgical knives. STEELE, W. E. Feb. 16, 1948, No. 4428. Convention date, June 4, 1946. [Class 81 (ii)] [Also in Group XXIII] The detachable blade of a scalpel has a centrally placed aperture which engages over a headed pin projecting laterally from the handle and the handle has restraining means engaging the butt end of the blade to prevent sideways or lengthwise movement thereof. In one form the blade 1, having a cutting edge 10, has a rectangular slot which, when set transversely to the handle, passes over the correspondingly shaped head of a pin 21 attached to an extension 20 of the handle 2. The blade is then turned about the pin until its end 12 rides up a chamfered surface 24 and snaps into a recess 22. The face of the handle extension against which the blade rests is slightly concave, so that the blade is maintained bent and so urged into the recess and, at the same time, positively pressed outwards against the head of the pin. The handle extension 20 is made narrower than the handle itself, over the greater part of its length, to enable the blade to be gripped when it is to be renewed. Other shapes of pin and slot may be employed, and attachment of the blade may be done by longitudinal instead of rotational movement.

Title: Improvements in and relating to the manufacture of vitaminous products
Filed: 1929-02-09
Abstract: 305,929. Helholt, K. Feb. 11, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Medicines for internal use.-Vitamins are transferred from an oil such as cod liver oil to another oil by adding to the first a quantity, which may be small, of an unsaponifiable, edible, and non-volatile oil, for example, pure paraffin or other hydrocarbon oil having the same boiling point as paraffin, the purpose of which is both to protect the vitamins and to extract them from the soap formed during subsequent saponification. The saponification is carried out in known manner, preferably in a nitrogen atmosphere, with a base such as potassium hydroxide, forming an almost dry soap, and a suitable solvent such as acetone is added to extract the added paraffin or other unsaponifiable oil together with the vitamins which it now contains. The oil. for example, earth nut oil, to which it is desired to transfer the vitamins may be added at this stage to the extract, which is then subjected to a further treatment during which the greater part of the solvent is separated without distillation. This may be done by adding distilled water, in which case practically all the acetone separates in one layer, together with the glycerine which was formed during the saponification. The other layer contains most of the vitamins originally present transferred to the second oil, as well as the added unsaponifiable oil, which may be allowed to remain in the final product. A short steam-distillation at a low temperature is desirable in order to remove the last traces of acetone. The product is used in the manufacture of medicines. An example is given.
