Abstract: 1507341 Simultaneously spraying liquid materials RANSBURG CORP 18 March 1975 [8 April 1974] 11316/75 Headings B2E and B2L In spray - depositing a two - component material, one liquid is sprayed by a first gun and charged by an electrostatic field established between a high potential electrode and a substrate at low potential, and a second liquid is sprayed by a second gun, there being an electric field between said electrode and said second spray such that said second spray is oppositely charged to aid first and attracted thereto, the mixture retaining a net charge which causes it to be attracted to said substrate by said first-mentioned electrostatic field. The apparatus may be used for depositing a curable resin, e.g. a cobalt naphthenate promoted polyester, which is sprayed through guns 15 charged by supply 29 to a high potential, e.g. 60KV, toward an earthed substrate 12; a catalyst, e.g. methyl ethyl ketone peroxide is sprayed in smaller amount (1/20 that of the resin) through a gun 16 which is earthed. The catalyst spray is thus attracted to the resin spray, but does not neutralise the field so that the mixture is attracted to the substrate. A cutter 26 may cut and triboeleotrically charge glass fibre 27 so that this also is electrostatically attracted into the spray and onto the substrate. Spray gun constructions are described.

Abstract: 1492165 APC systems INTERNATIONAL BUSINESS MACHINES CORP 24 March 1976 [25 April 1975] 11806/76 Heading H3A A synchronization arrangement for adjusting the phase of clock signals defining the sampling instants of a received digital data i.e. a modulated carrier fc comprises a controlled oscillator 14 for producing the clock signals and a control circuit 15 including (see Fig. 3) a first filter 16 for extracting from the received signal an upper sideband component of phase # 1  and frequency fc + 1/2T, where 1/T is the data rate, a second filter 18 for extracting a lower sideband component of phase # 2  and frequency fc-1/2T, a circuit 17, 19, 20 for producing from the two components a signal representing # 2 -# 1  for controlling the clock signals. The oscillator may be a quartz oscillator providing a squared output and applied to a set of dividers whose division ratio is varied by the error control signal produced by circuit 15 so that the clock sampling instants at 4 correspond to specific instants in the received data and associated with particular sideband information. The sampled data may be applied via an A/D converter 6 or direct to the control circuit 15. The filters 16, 18 may be narrow-band recursive digital filters (Figs. 4, 8, not shown). The filtered outputs are multiplied at 17 and low pass filtered at 19 and applied via a circuit 20 to obtain a sinusoidal function of the phase error. The need for a low-pass filter may be obviated by employing filters 16, 18 which produce quadrature outputs (Figs. 6, 9, not shown). A second order feed-back loop (Fig. 7, not shown) provides better frequency drift correction. For synchronizing the receiver and transmitter clocks, an initialization sequence may be transmitted before the data and the receiver may be modified (Fig. 9, not shown) to selectively respond to the sequence and the following data. Further sync information may be sent at regular intervals before and after each data transmission.

Title: Landing selector apparatus
Inventor: VOIGT HERBERT FREDRICK
IPC: B66B1/16
Filed: 1969-03-06
Abstract: 1,204,993. Lift control systems. OTIS ELEVATOR CO. 6 March, 1969, No. 11987/69. Heading B8L. [Also in Divisions G1 and H2] In a system for causing a lift car to stop accurately at a selected landing, in which the distance between the car and the landing is detected by primary (coarse) and secondary (fine) means, the secondary means comprises a circular potentiometer whose track is less than 360 degrees and whose slider makes one complete revolution as the car travels between successive landings. The system operates as follows: when the car 10 is running its position in the shaft is represented by the voltage on the slider BRI of a multi-turn potentiometer P1, one end of which is earthed through contacts KH1. This voltage is applied through contacts KH3 to a summing amplifier ADSUM, the other input to which is a negative voltage representing the stopping distance of the car at the speed at which it is travelling, and is provided by thecharge on a capacitor QA which is limited by the voltage from a tachogenerator 17 applied through a network VCL which biases the speed signal by a voltage equivalent to a distance of fifteen feet. The output of ADSUM thus represents the point at which the car can stop at any instant and this is compared in turn with voltages from fixed potentiometers IRE3 &c. representing the position of respective landings. When coincidence occurs a logic 1 signal is sent over corresponding line 1C, 2C or TC to a logic circuit (Figs. 2 and 3, not shown) which contains information of the next required stop. At the appropriate point in the travel, therefore, the stopping sequence is initiated, and this comprises the opening of contacts KH1 and KH3 and the closing of the appropriate one of contacts 1K1, 2K1 or TK1 so that potentiometer P1 is now connected as a bridge with the appropriate one of fixed potentiometer 1RE1 etc.; their sliders are set so that the voltage on slider BR1 now represents the distance between the car and its required stopping point. This constitutes the primary means, and the voltage from BR1 is applied to a " high-speed function generator " HSFG which effects slowing of the drive motor 14 in unspecified manner. At a point determined by the logic circuits the control is transferred to a low-speed function generator LSFG whose input comprises the " secondary means " and consists of a bridge composed of either rotary potentiometer PA or PB and the appropriate one of fixed potentiometers 1RE2, 2RE2 or TRE3. The sliders of PA and PB are driven together through a gearbox GB2 so that they make one revolution between landings and they are spaced so that one is on its track while the other is traversing the unusable portion. The car is finally stopped when this bridge is in balance.
