Title: Improvements in a universal joint
IPC: F16C11/06
Filed: 1934-03-22
Abstract: 424,805. Universal joints. THOMPSON PRODUCTS, Inc., 2196, Clarkwood Road, Cleveland, Ohio, U.S.A. March 22, 1934, No. 9044. Convention date, Aug. 10, 1933. [Class 65 (ii)] In a universal joint comprising a stud freely rotatable on its own axis and universally tiltable with respect to a housing, the stud bears in a seating member which bears in the housing, and the two sets of bearing surfaces converge in the same general direction and are urged in that direction by spring means, one set of bearing surfaces accommodating universal tilting movement of the stud in the housing while the other set accommodates rotary movement of the 'stud about its own axis. In the form shown, the stud 7, fixed in a member 33, has a frustoconical surface bearing in a member 14 which has a part-spherical outer surface bearing in a housing 5 screwed and clamped on the end of a rod 9. The bearing surfaces are pressed together by a spring 26 forcing a button 27 against the bottom of the member 14, in which a suitable bearing recess is formed ; the spring bears at its other end against a plate 24 closing the housing, and serves both to take up wear and to urge the stud 7 towards a position at right angles to the rod 9. A grub screw (not shown) in the housing engaging a vertical groove in the member 14, or equivalent means, is preferably provided to prevent rotation of this member about the axis of the stud, so that the bearing surfaces between the member 14 and the housing take only tilting movement of the stud, while rotation of the stud on its own axis is taken only by the bearing surface of the stud itself in the member 14. The upper end of the housing is closed by a washer 31 pressed down by a spring 32 bearing against the underside of the member 33 and thus assisting the spring 26 in pressing the bearing surfaces together. In a modification, the end of the stud is formed as a ball, the bearing member 14 having a part-spherical inner surface and a frusto-conical outer bearing surface ; in this form the set-screw is carried by the member 14 and engages a groove in the ball, and the spring 26 bears directly against the bottom of the ball. Either form of joint allows the frictional resistance to rotation of the stud to be determined independently of the resistance to tilting, by altering the angle of the conical bearing surfaces to vary the effective pressure thereon, that on the spherical surfaces being unaffected.

Title: Photocomposer motor speed control
IPC: B41B27/28
Filed: 1975-03-06
Abstract: 1498723 Automatic control of photocomposing ADDRESSOGRAPH-MULTIGRAPH CORP 6 March 1975 [3 July 1974] 9444/75 Heading G3N A photo-composing machine has a rotating disc bearing characters which are optically projected on to a sensitive surface. The speed of a motor which rotates the disc is regulated in accordance with-the point size selected for each character in order to optimize exposure time. As shown in Fig. 1, an opaque disc 10 carries transparent characters which may be projected by a lamp 12 through a lens system 14 on to a photosensitive sheet 15. In operation, the disc 10 is continuously rotated by a DC motor 11, supplied over a transistor switch 42. The speed of the disc is varied according to the point size of the character to be printed, since a slow speed produces a better exposure for a large character. This information is contained in a program register 36 which sets the ratio of a divide counter 34 receiving pulses from a master clock 30 and divider 32. The output of the counter 34 forms a motor speed reference signal which is compared in a shift register 18 with the frequency of pulses derived by an optical sensor 26 from a strobe track on the disc 10. The register is shifted in opposite directions by the two inputs, and an output signal 40 dependent on the state of an intermediate flip-flop produces impulses at a frequency which regulates the speed of the motor 11 to a valve determined by the register 36.

Patent GB-1584845-A (GB)
Title: Disinfectant concentrates
IPC: A01N59/10
Filed: 1978-03-10
Abstract: The invention relates to disinfectant concentrates for the beverages industry which contain a combination of nitric acid, hydrofluoric acid and water. Substances which are employed as disinfectants for destroying germs found in the pipes, tanks and apparatus of the beverages industry due to contaminant residues are chlorine-releasing substances, quaternary ammonium compounds, iodophores and peracetic acid in an equilibrium with hydrogen peroxide. The disadvantages of these compositions are that they are malodorous, bulky, foaming or have a limited spectrum of germicidal action. Nitric acid on its own is unimportant as a disinfectant since it is aggressive in character. Hydrofluoric acid has germicidal properties, but has not been employed due to its toxicity and corrosiveness. In a combination of hydrofluoric acid with nitric acid, lower concentrations suffice to kill the yeasts and bacteria when allowed to act over a short period. Nitric acid on its own only kills bacteria but is ineffective against yeasts. Hydrofluoric acid at low concentrations is ineffective against most bacteria. The combination of nitric acid and hydrofluoric acid is active against all bacteria found in the beverages industry and has a synergistically increased activity against yeasts.

Title: Improvements in dials
IPC: H03J1/04
Filed: 1925-04-14
Abstract: 234,068. British Thomson-Houston Co., Ltd., (Assignees of Langley, R. H.). May 17, 1924, [Convention date]. Diads and scales; index hands and pointers; indicating particular readings.-Relates to dial and pointer devices for indicating a number of desired angular positions of a rotatable spindle. The invention is particularly adapted for use on wireless receiving apparatus, to provide a convenient means for noting the various positions in which condensers &c. should be set for tuning-in different stations. A number of pointers of different lengths are attached to the rotatable spindle, which is surrounded bv a dial having a number of circles concentric with the spindle; each circle has a radius equal to the length of one or more of the pointers, and any particular setting can be noted by marking the position of any one of the pointers on the corresponding circle or arc over which it moves. The Figure shows the application to a condenser in which the spindle can be rotated through 180 only. A paper &c. dial 4 is removably secured over the ordinary fixed dial 3, bv means of a resilient split ring 16 and a screwed-on ring 18. On the end of the spindle 14 is attached a four-armed pointer 5; the longer pair of arms 6, 8 may be equal, and extend to a circle 11, whilst the shorter arms 7, 9 may both be substantially equal to the radius of a circle 10. The upper half of the circle 11 may be graduated in degrees, as shown. When the set in which the apparatus is used is tuned to receive a particular station, the angular setting is recorded (together with the call-sign of the station) bv a mark on the dial opposite any one of the pointer arms. In the application to a receiver of the superheterodyne type, the aerial tuner is provided with a paper dial having an arbitrary scale and the dial for the oscillator tuning means is calibrated by experiment to correspond with the readings on the other dial.
