Title: Windscreen wiper drive mechanisms
Inventor: SIMPSON WILLIAM EDWARD
IPC: B60S1/18
Filed: 1962-10-09
Abstract: 978,840. Windscreen wiper drive mechanisms. GENERAL MOTORS Ltd. Sept. 26, 1963 [Oct. 9, 1962], No. 38106/62. Heading A4F. The drive mechanism for a windscreen wiper comprises a crank mounted on the rotary drive shaft 1 for transverse movement relative thereto on stopping the wiping action, whereby the effective throw of the crank is increased to move the wiper blade assembly to a parked position off the screen. Crank arms 4 and 7 are held together by the shaft 1 which extends through a slot 3 in arm 4 and is screwed to arm 7, and attached to arm 4 a pawl 12 having a tooth 14 which abuts a shoulder 17 on arm 7 and is secured to the opposite side of arm 7 by spring means 15 to prevent relative sliding movement between the two crank arms. The wiper blade assembly is attached through linkage means to crank pin 5 which extends through slot 6 in arm 7. In operation when the wiping action is to be stopped a detent 20 moves to a position shown in dotted lines in Fig. 3 and as the crank rotates pushes pawl 12 out of latching engagement with arm 7 so that as cam surface 19 on the crank arm 4 moves over the detent this arm moves relative to arm 7 so that the pin 5 is at the open end of slot 6 i.e. the radial distance of the crank pin from the rotary drive shaft 1 is increased whereby the effective throw of the crank is increased and the upper blades move off the windscreen into a parked position.

Title: Apparatus for transporting punched cards and similar data carriers
IPC: G06K13/103
Filed: 1962-10-09
Abstract: 944,196. Feeding sheets. SIEMENS & HALSKE A.G. Oct. 9, 1962 [Oct.16, 1961], No. 38130/62. Heading B6B.  The apparatus claimed in Specification 941,218 is modified in that the slot 5 between the front plate V1 of the magazine for a stack V of information-carrying cards, and the base thereof, can be adjusted automatically to prevent two successive cards being fed out simultaneously until the first of these has been fed out of the stack by a predetermined amount. This arrangement prevents the two lowermost cards of a new stack being fed out of the stack to the feed rollers 2 whilst superpositioned. The plate V1 is raised and lowered by an electromagnet E controlled by a photo-electric cell F and light source L, and until the light ray is interrupted by the presence of a card passing to the rollers 2, the plate VI is in the lower position to permit only the lowermost card to pass through the slot S. Immediately the card breaks the light ray, the plate V1 is lifted to permit two cards to pass through, and continuous feed of the successive cards in staggered relationship commences. The card-separator roller 1 is spaced from the trailing edge of the lowest card by a distance of one quarter of a card length, and the distance between the roller 1 and rollers 2 is, equal to one card length, and the light ray is interrupted to cause the slot S to be widened to permit simultaneous passage of two cards, when one third of a card projects through the slot S. The second set of feed rollers 3 rotatate at higher peripheral speeds than the rollers 2, the latter rotate faster than the roller 1, and all the rollers have the same diameter. The photo-electric device F, L could be replaced by a mechanical device directly actuated by the cards.

Title: Medical ventilator including a fail-safe system
Inventor: SMYTHE G E
IPC: A61M16/00
Filed: 1971-08-19
Abstract: 1293479 Respiratory appliances PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Aug 1971 38980/71 Heading A5T In a time cycled medical ventilator, driving gas is supplied from a source DG via an energised solenoid operated valve S1, to a port 1 of a pneumatically operated driving cylinder D.C.1 thus forcing the piston downwards to contract bellows B1 and B2 and expel therefrom a volume of respiratory gas. At the same time solenoid DS1 is de-energised to allow inspiratory valve I.V. to open so allowing the respiratory gas to pass at a rate determined via a flow rate controller F.R.C. to the patient via a non-return valve N.R.V.2 and gas is vented from the non-driving chamber of the driving cylinder to atmosphere via de-energised solenoid operated valve S2. When inspiration of respiratory gas is complete the solenoid of valve S.1 is de-energised and the solenoid of valve S.2 energised, so that driving gas is fed to port 2 of the driving cylinder, and vented to atmosphere via port 1 and valve S.1, the bellows being thus expanded to draw in respiratory gas via inlet RG and non-return valve N.R.V.1. Inspiratory valve I.V. is closed by energisation of solenoid D.S.1 and expiratory valve E.V. opened by de-energisation of solenoid D.S.2. A pressure relief valve comprises a valve member V.M., a valve seat V.S., and a weight W disposed on a lever arm L.A. pivoted at P. to limit the maximum pressure in the inspiration gas passage. A detecting means is arranged to open the relief valve to allow the patient to breathe if the driving gas supply fails, and comprises a variable capacity gas reservoir G.R. which is charged with driving gas via non-return valve N.R.V. 4 or N.R.V. 5, and vented to atmosphere via flow restrictor F.R. at a rate slower than the rate at which driving gas can be fed to the reservoir, so that if the driving gas supply fails the piston rod of the reservoir rises to engage the lever arm of the relief valve and opens it, but in normal operation the piston rod never reaches this height.

Title: Solid state radar
Inventor: BULMAN PETER JOSEPH
IPC: H01L47/00
Filed: 1967-08-25
Abstract: 1,234,764. Pulse radar; Gunn-effect circuits. NATIONAL RESEARCH DEVELOPMENT CORP. 23 Aug., 1968 [25 Aug., 1967], No. 39181/67. Headings H3T and H4D. A radar includes a solid-state microwave source (e.g. a Gunn diode), a power supply and means 11 for applying the power supply to the microwave source for a short duration (e.g. 10 nanoseconds). Diode 1 is in a cavity 3 at the end of a waveguide 5, the cavity being turned by a short circuit 7. One terminal of the diode is connected via R.F. by-pass 9 to an avalanche transistor switch 11, one end of which is connected to an end of an open-circuited delay line 13 charged from a source 17. If T is the delay in line 13, the diode is extinguished after time 2T. A shorter pulse can be achieved by using a higher charge than that required to make the diode avalanche, Fig. 2 (not shown), i.e. the diode quenches itself in a shorter time than 2T. In a further embodiment a source (29, Fig. 3) feeds microwave power into the transmitter cavity (21) before the driving pulse applied, this improves pulse-to-pulse informity of amplitude in the output.

Title: Improvements relating to Field Effect Transistors
Inventor: STATZ HORST F
IPC: H01L29/78
Filed: 1968-08-16
Abstract: 1,181,330. Field-effect transistors. INTERNATIONAL BUSINESS MACHINES CORP. 16 Aug., 1968 [25 Aug., 1967], No. 39219/68. Heading H1K. Field-effect transistors are made in high resistivity gallium arsenide substrates, the channels being formed by heating the substrates in vacuo until a thin N-type surface layer is formed. It is believed that the N-type layer is formed by out-diffusion of chromium to leave uncompensated donors. Formation of the layer is influenced by the presence of a silica coating; with thick silica the layer is not formed. Embodiments described are Schottkygate-FET, JUGFET and IGFET. Channel limiting may be achieved by P-type diffusion, by mesa-etching, or by leaving a thick silica ring during manufacture so that a zone of the original high resistivity material terminates the channel. The silica used may contain phosphorus pentoxide. The oxide may be removed in the gate area of an IGFET and replaced by silicon nitride. Ohmic contact materials for the GaAs are Au-Te, Ag-Te and Sn. Schottky barrier materials are Au, Cr, Ni and Mo. Isolation rings and junction gates may be formed by Zn diffusion (from an arsenide source). Ohmic contents to P-type zones use Au-Mg or Ag-Mg. Mesa-etching uses warm dilute NaOCl.

Title: Method of shoe making
IPC: A43D25/053
Filed: 1965-09-20
Abstract: A method of making a shoe includes the steps of moulding the back part of a shoe upper to the shape of the last upon which it is to be lasted, adhesively attaching the lasting margin at the back part to the insole so that the tip of the upper and insole coincide, mounting the assembled upper and insole on a last without tacking the insole or upper to the last, adhesively lasting the toe portion and then adhesively lasting the side portions.  As described the back part of the upper is moulded in a back part moulding machine having a heel form, an articulated three-part female mould which is pressed against the heel form, and wipers which wipe the lasting margin over an adhesive coated insole.  The insole is positioned on the heel form by two pins on the heel form which engage holes in the insole.  The assembled upper and insole is then positioned on the last by pins on the last engaging the holes in the insole.  The upper is then lasted in a conventional toe lasting machine and is then transferred to a progressive side lasting machine.

Abstract: 1477833 Data processing; counting apparatus NATIONAL RESEARCH DEVELOPMENT CORP 14 Aug 1974 [24 Aug 1973] 40266/73 Heading G4D In a data processing apparatus similar to that described in Specification 1,401,009, in which two binary signals are compared by feeding one to the data input of a stepping register, recording a count in an individual counter each time the state of a stage of the register is the same as the other signal and causing the counter which first reaches a predetermined count to generate a signal, the stepping register is divided into a plurality of groups of stages, each group being clocked at a lower rate than the preceding group. In a practical embodiment (Fig. 3, not shown) there are three groups of stages, the first group clock input is directly connected to the clock generator while the second is connected via a divide by two circuit and the third is derived from the second by a further divide by two. Since the flow rate measured by the apparatus is inversely proportional to the delay it is possible with the above arrangement to achieve the same accuracy over a range of flow rates using a smaller register.
