Title: Improvements in and relating to remote control systems
IPC: G08C19/12
Filed: 1953-08-04
Abstract: 732,320. Electric control systems. GENERAL ELECTRIC CO. Aug. 4, 1953 [Aug. 1, 1952], No. 21486/53. Class 40 (1). Three control functions are effected by transmitting respectively electric oscillations (a) at a frequency f1, (b) at a frequency f2 and (c) at a frequency recurrently varying from f1 to f2 at a recurrence frequency less than f1 or f2. At the receiver, the control frequency f1  may be used, e.g. to cause a prime mover to deliver more power, f2 to reduce the power of the prime mover, and the varying control signal to preclude actuation of either of the other two controls.  Transmitter. In the lower position of a single pole-control switch 18 a relay 8 is held energized to short circuit, as shown, the input terminals 2, 3 of a transmitter 1 which is thereby caused to generate oscillations at a frequency f2. In the upper position of the switch the relay 8 is held de-energized by a low resistance 21 connected in parallel therewith. The input terminals 2, 3 of transmitter 1 are thereby open circuited causing oscillations at frequency f1 to be generated thereby. With the switch 18 in its central position the relay 8 self-interrupts, at a frequency determined by a capacitor 16, periodically to short and open circuit the input terminals 1, 2 whereby the transmitter frequency varies in step between f1 and f2. The output of transmitter 1 is transmitted over a carrier current channel la or by radio. Receiver. A discriminator 22, e.g. as disclosed in Specification 648,278, [Group XL (c)], develops any output of positive polarity across series connected load resistors 24, 25 when frequency f1 is received, a negative output when frequency f2 is received, and an alternating output at the " recurrence " frequency where a frequency modulated wave varying between the frequencies f1, f2 is received. When a control signal at frequency f1 is received, the positive signal potential at point 58 causes the associated tetrode 28 to conduct, energize a relay 48 to effect the desired control over contacts 51, 52 and at the same time preclude tetrode 33 from operating. When a control signal at frequency f2 is received tetrode 33 conducts, effects the desired control over relay 53 and contacts 52, 56, and effectively blocks tetrode 28. When the control signal received recurrently varies between f1 and f2, the alternating output at 57-58 is rectified at 41, 44, such that the rectified voltages appearing across capacitors 42, 45 reduce the potentials of the grids positively to block both tetrodes 28, 33 and so preclude operation of either relay 26 or 27.

Filed: 1935-07-29
Abstract: 454,685. Snap-action switches. HOBART MANUFACTURING CO., Troy, Ohio, U.S.A.- (Assignees of Meeker, D. A.) July 29, 1935, No. 21524. Convention date, Aug. 13, 1934. [Class 38 (v)] [See also Group II] A motor switch 76 cannot be switched on by means of a lever 71 until the dial 30 of a coffee mill has been moved into a position to select a particular grade of coffee and cannot be switched off by a spring 80 until the dial has been returned to its "off " position. The switch 76 is connected by a link 75 to a hook 73 mounted on a shaft 70, the hook being provided with a pawl 77 limited in its movement by a pin-andslot 78 and controlled by a spring 79. When the dial 30 is in the " off " position the bar 86 engages a projection on the back of the disc and the pawl 77 rests on the bent end 87 of the bar so that the lever 71 cannot be raised to operate the switch. When the dial is turned to select a grade of coffee, the bar 86 moves into a recess and the end 87 clears the pawl 77 to permit switch lever 71 to be raised and retained in that position by the hook 73 engaging the end 87 of the bar. When the coffee has been ground the dial is turned to the " off " position, the bar 86 is pushed back by the projection and the end 87 clears the hook 73 to permit the spring 80 to return the switch to its " off " position. A single motor may drive two mills each having a switch operating gear connected to the switch by a slotted link. A finger on the shaft 70 may also trip a tumbler switch of an indicator.

Title: Improvements in or relating to molds for casting metals
IPC: B22D15/02
Filed: 1928-08-21
Abstract: 325,553. White, A. E., (Aluminium, Ltd.). Aug. 21, 1928. Cores; moulds; clamping moulds.-Permanent moulds for casting metals having melting points as high as or higher than aluminium and its alloys are particularly designed to avoid warping due to unequal expansion of the moulds during use. A metal mould for casting pistons comprises a base 40, Figs. 1 and 2, having a central aperture 43 to receive a removable circular pilot 42 secured by screws 45. The top of the pilot is flush with the top of the base except for the central portion 46 which forms the bottom of the casting cavity. The pilot is interchangeable with others for producing pistons of different size and shape and may be made of hardened steel, while the base is of cast iron. The mould halves 48 are thin, flat and substantially rectangular, are of approximately uniform thickness and have raised portions 60 formed on their outer sides extending from the upper to the lower edges thereof, these portions 60 containing the casting cavity 47 which is confined to the lower portion of the mould in proximity to the base. The mould halves are pivoted by hinges 49 on a pin 51 which engages a slightly enlarged hole 52 in the base to allow movement of the mould halves thereon. The mould is clamped by an arm 53 rotatable on a stud 54 and having pivoted thereto a lever 55 whose end 56 engages an inclined wear plate 57 secured to the mould half. A guide 58 locates the arm 53 in the locked position. The bottom surfaces of the mould halves are recessed to engage the projection 46 on the pilot and the walls 59 and 60 are recessed to provide a casting cavity 47, riser cavities 61 and a gate cavity 62. Above the cavity 47 a recess 63 receives semi-circular bushes 64 which clamp the main core sections together and position them. The main core comprises a central section 66a and two side sections 66<b> having flanges 66<c> seating on top of the bushes 64. Additional cores 67 for producing the wrist pin bosses in the piston are supported in, bushes 68 secured to the mould by screws passing through their flanges. The mould halves are relieved on their contacting surfaces at 72 so as to make contact over a horizontal length slightly greater than the length of the cavities 47, 61 and 62 and for a short distance only between the cavity 61 and the hinge pin in order to reduce the distortion of the mould during casting. The outer surfaces of the mould halves are plane surfaces free from outstanding webs &c. to allow of their being cast in permanent moulds in order to reduce their porosity. The slight additional thickness of the raised portions 60 allows different sized casting cavities to be formed in mould halves of standard size and the base 40 may also be of standard size and used with pilots 42 of different shapes. The invention may also be applied to a mould in which the halves are clamped instead of being hinged together.
